AI Technical Summary
Current treatments for angina, myocardial infarction, reperfusion injury, ventricular arrhythmias, cardiac pump failure, congestive heart failure, and other cardiac conditions do not effectively address the life-threatening elevations in late sodium current (ILATE) caused by hypoxia-induced SUMOylation of the cardiac sodium channel NaV1.5.
Administering compounds or compositions that modify the NaV1.5 K442 residue to prevent SUMOylation, thereby inhibiting pathologic elevations in intracellular late sodium current (ILATE). This can be achieved using drugs such as subasumstat, TAK-981, or other SUMOylation inhibitors, or through genetic methods like CRISPR to alter the NaV1.5 gene.
The proposed solution effectively suppresses hypoxia-induced SUMOylation of NaV1.5, reducing life-threatening elevations in late sodium current and alleviating symptoms of various cardiac conditions, including angina and myocardial infarction.

[0008] TECHNICAL FIELD
[0009] This invention generally relates to biology and medicine. In alternative embodiments, provided are methods for treating, ameliorating, lessening the symptoms of, or preventing, angina, myocardial infarction, reperfusion injury, a ventricular arrhythmia (VA), cardiac pump failure due to myocardial infarction (MI) (optionally cardiac pump failure due to myocardial infarction (MI) in an early ischemia / reperfusion (I / R) period), congestive heart failure (CHF), hypovolemia, acidosis, hyperkalemia, hypokalemia, a cardiac poisoning or cardiopathology due to a toxin or poisoning, cardiac tamponade, tension pneumothorax, coronary thrombosis, sepsis, shock, pulmonary thrombosis, pulmonary embolism, respiratory decompensation, arrythmia a cardiac event caused by hypoperfusion and / or cardiac arrest, comprising administering to an individual in need thereof comprising suppressing hypoxia-induced SUMOylation of the cardiac sodium channel NaV1.5, a post-translational modification (PTM) that we have shown produces life-threatening elevations in the late Na+ current.
[0010] BACKGROUND
[0011] SUMOylation is a process in which SUMO proteins are covalently attached to specific lysine residues in target proteins, thereby regulating various aspects of protein function. SUMO (Small Ubiquitin-like Modifier) proteins are a family of small proteins that are covalently attached to and detached from other proteins in cells to modify their function. SUMO proteins are similar to ubiquitin and are considered members of the ubiquitin-like protein family. SUMOylation is directed by an enzymatic cascade analogous to that involved in ubiquitination. In contrast to ubiquitin, SUMO is not used to tag proteins for degradation. Mature SUMO is produced when the last four amino acids of the C-terminus have been cleaved off to allow formation of an isopeptide bond between the C-terminal glycine residue of SUMO and an acceptor lysine on the target protein. Human SUMO proteins include SUMO1, SUMO2, SUMO3 and SUMO4.
[0012] SUMO attachment to its target is similar to that of ubiquitin; however, the SUMO precursor has some extra amino acids that need to be removed, therefore a C- terminal peptide is cleaved from the SUMO precursor by a protease (in human these are the SENP proteases) to reveal a di-glycine motif. The obtained SUMO then becomes bound to an El enzyme (SUMO Activating Enzyme 1 (SAE)) which is a heterodimer (subunits SAE1 and SAE2). It is then passed to an E2 enzyme, which is a conjugating enzyme (Ubc9). In some cases, one of a small number of E3 ligating proteins (or enzymes) speeds or makes more specific the conjugation process to select targets.

[0091] The drawings set forth herein are illustrative of exemplary' embodiments provided herein and are not meant to limit the scope of the invention as encompassed by the claims.
[0092] FIG. 1 schematically illustrates SUMO pathway and inhibitors: 1. Maturation; SUMO pro-peptide is cleaved at C-terminus by SENP exposing Gly-Gly; 2. Activation. SUMO-activating enzy me (El) forms a thioester to yield El-GG-SUMO; 3. Conjugation. GG-SUMO is transferred to E2 conjugating enzyme UBC9 (E2-GG- SUMO); 4. Ligation. SUMO is transferred to target Lys (K442 in Nav1.5); for some targets, E3 ligases speed SUMOylation or increase specificity. 5. SENP deSUMOylases remove SUMO from targets. Site of inhibition: TAK-981 via El, 2- DO8 via E2, as described in detail in Example 1, below.
[0093] FIG. 2 schematically illustrates how hypoxia induces NaV1.5 SUMOylation on K442 so channels reopen late in the cardiac AP when normally inactive, raising ILATEto approximately 4% of peak as seen with VA and sudden cardiac death (1), as described in detail in Example 1, below.
[0094] FIG. 3A-C illustrate thatNaV1.5-K442 is required for hypoxic SUMOylation and ILATE: ILATEwas studied at -30 mV, 50 and 100 ms after the peak current and is presented as mean % of the peak. The time course for hypoxic modulation was studied with steps from -100 mV to -30 mV every' 10 s. Single-channel currents were studied in cell-attached mode and elicited every 5 s by a 50-ms depolarizing pulse to - 30 mV from a holding potential of -120 mV. Data were recorded at filter and sampling frequencies of 5 and 50 kHz, respectively, and processed offline using a 1.2- kHz Bessel filter for display. For each cell, sweeps with no channel activity (null) were averaged offline, and subtracted from the data sweeps before analysis:

Stoichiometric (photobleaching) and pixel- by -pixel analysis for subunit density and co-localization were performed and Manders’ coefficients for colocalization assessed post hoc for 3-5 regions per cell; co-localization was defined as the presence of both fluorophores at more than 30% of the maximum fluorescence level recorded in that stack (overlap is represented in images as white pixels). The time course of hypoxic modulation of NaV1.5 ILATEwas studied as in Fig 3:

[0149] FIG. 20 illustrates Table 1 and Table 2 showing data that human NaV1.5 in HEK293T cells with NaVpi, whole cell recording as in Fig 3. Data are mean ± SEM, 4-8 cells per group. TAK-981 was applied at 15 uM and 2-D08 at 20 uM:
[0150] Table 1 shows + / - 10 nM SUMO1 in the pipette after inhibitor pre-treatment for various times; and
[0151] Table 2 shows pre-treatment for 4 h with hypoxia (1.5% O2), as described in detail in Example 1, below.
[0152] FIG. 21A-B illustrates how NaV1.5 is SUMOylated: previously shown using FRET and TIRF microscopy (and functional studies with wild type and Nav1.5- K424Q to ablate SUMOylation by removing the site for attachment) we show here human NaV1.5 channels expressed with NaVpi and HA-tagged SUMO in HEK293 cells subjected to immunoprecipitation (IP) using anti-NaV1.5 (FIG. 21A, left) or anti-SUMOl (FIG. 21 B) antibodies and separation on SDS-PAGE gels. With both IP antibodies, SUMOylation of Nav1.5 is demonstrated by immunoblotting (IB) because SUMO1 and NaV1.5 are co-purified. When HEK293 cells were pre-treated by 15 pM TAK981 for 4 hrs prior to IP, NaV1.5 SUMOylation was decreased indicating its ability to suppress SUMOylation. Demonstrating specificity, IP with non-immune IgG isolated neither SUMO norNaV1.5. WCL, whole cell lysate.
[0153] FIG. 22 illustrates data showing myocardial ischemia and reperfusion (MI / R) leads to SUMOylation of NaV1.5 in vivo that is suppressed by intravenous administration of TAK-981. Protection previously shown using functional studies with wild ty pe and Navl.5-K424Q knock-in mice to ablate SUMOylation (removing the site for attachment), and TAK-981, is supplemented here by showing the effectiveness of TAK-981 in vivo by direct visualization of the channel-SUMO complex isolated from mouse heart. Wild type mice were subjected to MI / R (45-min ligation of the left anterior descending artery followed by 30-min of reperfusion), + / - TAK-981 at 7.5 mg / kg IV at the time of ligation. With MI / R, SUMOylated NaV1.5 was isolated from the free wall (frank infarct) and septum (spared) of heart (red arrow, mouse 17) that was decreased when mice were treated with TAK-981 (red arrow, mouse 12). The results were confirmed in repeat studies on two other pairs of treated and untreated mice.
[0154] FIG. 23A-C illustrate data showing that NaV1.5-K442Q knock-in (KI) mice removes the channel site of SUMOylation and protect mice from MI / R -induced tissue damage. KI mice that cannot be SUMOylated on K424 show less cardiac troponin release 24 hours after MI / R (FIG. 23 A) and less collagen deposition 2 weeks post MI / R (FIG. 23B-C) compared to WT animals. This validates the claim of protection afforded by suppression of SUMOylation.
[0155] FIG. 24A-B illustrate data showing that MI / R-induced late current (NaV1.5 channel ILATE) is suppressed inNaV1.5-K442Q KI mice (that are not SUMOylated) and wild type mice (WT) treated with TAK-981. A significant increase in ILATEis recorded in myocytes isolated from the left ventncular anterior wall of WT mice immediately after MI / R (45 min ischemia and 30 min reperfusion) compared to sham (surgery but no ligation). The increase in ILATEis not seen in KI mice or WT mice treated with TAK-981 given at the time of MI / R. FIG. 24A exhibits representative traces of cells from WT and KI post MI / R or sham, with or without TAK-981 treatment. The statistical analysis of ILAIE in the 5 different groups is summarized in FIG. 24B. This directly proves operation of the proposed mechanism of protection in cells from mouse heart.
[0156] FIG. 25A-E illustrate data showing that NaV1.5-K442Q knock-in (KI) mice are protected from MI / R-induced altered calcium flux and decreased shortening. Validating that suppressing SUMOylation and ILATEdecreases downstream pro- arrhythmic effect of alter calcium flux in vivo. WT and NaV1.5-K442Q KI mice were studied by simultaneous measurement of Ca2+ transients (CaT) using Fura-2 dual- wavelength ratiometric method and sarcomere shortening by IONOPTIX™ detection (lonOptix Co) and fast Fourier transform (FFT) analysis. A significant decrease in sarcomere shortening (FIG. 25A-B) and CaT amplitude (FIG. 25C-D) was observed in WT after MI / R (45 min ischemia and 30 min reperfusion). The changes were abrogated in KI mice (FIG. 25A-D). There is a trend towards a delay in CaT decay in WT after I / R, but the data were not significant (FIG. 25E).

[0158] DETAILED DESCRIPTION
[0159] In alternative embodiments, provided are methods for treating, ameliorating, lessening the symptoms of, or preventing: angina, myocardial infarction, reperfusion injury, a ventricular arrhythmia (VA), cardiac pump failure due to myocardial infarction (MI) (optionally cardiac pump failure due to myocardial infarction (MI) in an early ischemia / reperfusion (I / R) period), congestive heart failure (CHF), hypovolemia, acidosis, hyperkalemia, hypokalemia, a cardiac poisoning or cardiopathology due to a toxin or poisoning, cardiac tamponade, tension pneumothorax, coronary thrombosis, sepsis, shock, pulmonary thrombosis, pulmonary embolism, respiratory decompensation, arrythmia a cardiac event caused by hypoperfusion and / or cardiac arrest, comprising administering to an individual in need thereof comprising suppressing hypoxia-induced SUMOylation of the cardiac sodium channel NaV1.5, a post-translational modification (PTM) that we have shown produces life-threatening elevations in the late Na+ current. We have demonstrated in mice a novel strategy to subdue ventricular arrhythmias (VA) and pump failure due to myocardial infarction (MI) in the early ischemia / reperfusion (I / R) period (events associated with humans’ sudden death). The method suppresses hypoxia-induced SUMOylation of the cardiac sodium channel NaV1.5, a post-translational modification (PTM) that we have shown produces life- threatening elevations in the late Na+ current (ILATE).
[0160] While the invention is not limited by any particular mechanism of action, the rationale for methods as provided herein is five-fold. First, ILATEis associated with death in 25% to 50% of patients with MI and I / R due to arrhythmias including ventricular tachycardia (VT), ventricular fibrillation (VF), and torsade de points (TdP). Second, we have demonstrated that hypoxia produces pathologic levels of ILATEin under 1-min due to SUMOylation of NaV1.5 channels on a single residue, lysine 442 (K442). and that ILATEis eliminated by mutation of the site so it is no longer subject to SUMOylation (NaV1.5-K442Q), or by application of a deSUMOylating enzyme. Third, the preliminary results shown here include a knock- in (KI) mouse strain we created, NaV1.5-K442Q, that ablates NaV1.5 SUMOylation MI. 45-min left anterior descending coronary artery (LAD) ligation, manifest VA, whereas the KI mice show decreased VA and left ventricular (LV) dysfunction compared to the WT mice. Fifth, we show- that tw o SUMO pathway inhibitors, one in phase I / II cancer trials as a transcriptional regulator, suppress Navi.5 SUMOylation, ILATE, VA, and ameliorate LV dysfunction in WT mice subjected to LAD ligation. Based on these findings, inhibiting NaV1.5 SUMOylation is a viable strategy to reduce VA and LV dysfunction in acute and post-acute phases of ML
[0161] Angina and heart attacks come from decreased blood flow' (ischemia) to the heart: the decrease in oxygen delivery (hypoxia) to the heart interferes with normal electric activity and normal pumping blood to the body. The earliest change is excess sodium going into the muscle cells and this is caused by the heart sodium channel (Nav1.5) opening abnormally late in the heartbeat when it is supposed to be closed (late sodium current). We have demonstrated that the late current is produced within a minute of hypoxia because enzymes act to link SUMO protein to the channel on one site (K442) and that no late current develops with hypoxia if the channel linkage site is mutated or the SUMO cannot attach or is cut off the channel. As described herein, we have studied the effects in wild type and knock-in mice and shown physiological effects that demonstrate new therapies to protect humans.
[0162] If the channel has a mutation at the site so it cannot be SUMOylated (K442 is changed) the mice are protected from cardiac rhythm disturbances and pump failure in response to preclinical model for heart attack (occluding the major vessel the feeds the heart, the left anterior descending artery). Moreover, we showed that giving compounds, TAK-981 or 2-D08, that block the enzyme from attaching SUMO to K442 protect wild type mice (TAK-981 has been used in phase I / II drug trials to treat cancer because the SUMO pathway has been known for controlling the expression of genes in the nucleus over days rather than the rapid effects we study of the SUMO enzymes at the cell surface) . Because these findings were generated in an art- accepted animal model for equivalent human cardiopathies, these data demonstrate that humans with angina, heart attack and heart failure can benefit from drug (for example, TAK-981 or 2-D08) or genetic therapies to stop SUMO attachment to the Nav1.5 channel at K442, as this stops the pathological late sodium current.
[0163] In alternative embodiments, treatments as provided herein can be by genetic methods, and can include: viral vectors or protein delivery via nanoparticles to alter the genetic code of NaVl .5 K442 to another residue so it cannot be SUMOylated, for example, by modifying the SCN5A gene or transcripts using CRISPR, prime editing, or other technologies.
[0164] Further, other causes of myocardial ischemia / hypoxia are therefore amenable to improvement via this approach (i.e., drug (for example, TAK-981 or 2-D08) or genetic therapies to stop SUMO attachment to the Navi .5 channel at K442); these include, but are not limited to, hypovolemia, acidosis, hyperkalemia, hypokalemia, cardiopathology due to a toxin, cardiac tamponade, tension pneumothorax, coronary thrombosis, sepsis, shock, pulmonary thrombosis, pulmonary embolism, respiratory decompensation, arrythmia and other causes of cardiac hypoperfusions and cardiac arrest.
[0165] We have showed that:
[0166] - the SUMO pathway can act at the cell surface, modifying ion channels to change their electrical activity.
[0167] - hypoxia regulates the SUMO effect on ion channels first in the CNS channel Navi.2 (for example in stroke), - hypoxia leads to SUMOylation of cardiac Navi .5 explaining late sodium current and the initial events (sodium loading) associated with hypoxia as seen with heart attacks.
[0168] As described herein, we tested the prediction for knock-in mice that changing the K442 site would protect the mice from the negative effects of left anterior descending (LAD) coronary artery occlusion for 45 min (to simulate a heart attack) and that treatment with compounds given as intraperitoneal injection that inhibit SUMOylation would also protect.
[0169] In alternative embodiments, the composition or a drug capable of suppressing hypoxia-induced SUMOylation of the cardiac sodium channel NaV1.5 comprises any compound capable of inhibiting SUMOylation at El (i.e., blocking formation of an El-SUMO intermediate, where El is El enzyme, or SUMO Activating Enzyme 1 (SAE)), E2 (i.e., blocking formation of an E2-SUMO intermediate (where E2 is an E2 conjugating enzyme), E3 (i.e., blocking formation of an E3-SUMO intermediate (E3 is a ligating protein)) or an unidentified site (i.e., blocking formation of any SUMO intermediate), for example, a drug or composition used in methods as provided herein, and to suppress hypoxia-induced SUMOylation of the cardiac sodium channel
[0170] NaV1.5, comprises any one or several of:
[0171] 1. compounds inhibiting SUMO El: 2. compounds inhibiting SUMO E2;
[0172] 3. compounds inhibiting SUMOylation with unknown sites:
[0173] El enzymes activate ubiquitin (Ub) and ubiquitin-like (Ubl) proteins in two steps by carboxy -terminal adenylation and thioester bond formation to a conserv ed catalytic cysteine in the El Cys domain. Ubiquitin (Ub) and ubiquitin-like (Ubl) proteins attached to their target proteins and modulating the activities of those targets in various ways. Three types of evolutionarily conserved enzymes are: El activating enzymes; E2 conjugating enzy mes; and, E3 ligase enzymes, and they act sequentially through parallel yet distinct pathways to conjugate ubiquitin and Ubl proteins, such as SUMO and NEDD8. to their targets. The El enzyme uses the adenosine triphosphate (ATP) and magnesium to adenylate the C -terminal Ub / Ubl glycine, releasing pyrophosphate and resulting in adenosine monophosphate (AMP).

In therapeutic applications, compositions are administered to a subject, e.g., a human in need thereof, in an amount of the agent sufficient to cure, alleviate or partially arrest the clinical manifestations and / or its complications (a“therapeutically effective amount”), for example, of angina, myocardial infarction, reperfusion injury, ventricular arrhythmias (VA), pump failure due to myocardial infarction (MI) in an early ischemia / reperfusion (I / R) period, and / or congestive heart failure (CHF), hypovolemia, acidosis, hyperkalemia, hypokalemia, cardiopathology due to a toxin, cardiac tamponade, tension pneumothorax, coronary thrombosis, sepsis, shock, pulmonary thrombosis, pulmonary embolism, respiratory decompensation, arrythmia and other causes of cardiac hypoperfusions and cardiac arrest..
[0229] The amount of pharmaceutical composition adequate to accomplish this is defined as a "therapeutically effective dose." The dosage schedule and amounts effective for this use, i.e., the “dosing regimen,” will depend upon a variety of factors, including the stage of the disease or condition, the severity of the disease or condition, the general state of the patient's health, the patient’s phy sical status, age and the like. Dosage levels may range from about 0.01 mg per kilogram to about 100 mg per kilogram of body weight. In calculating the dosage regimen for a patient, the mode of administration also is taken into consideration.
[0230] The dosage regimen also takes into consideration pharmacokinetics parameters well known in the art, i.e., the active agents' rate of absorption, bioavailability, metabolism, clearance, and the like (see, e.g., Hidalgo-Aragones (1996) J. Steroid Biochem. Mol. Biol. 58:611-617; Groning (1996) Pharmazie 51:337-341; Fotherby (1996) Contraception 54:59-69; Johnson (1995) J. Pharm. Sci. 84:1144-1146; Rohatagi (1995) Pharmazie 50:610-613; Brophy (1983) Eur. J. Clin. Pharmacol. 24: 103-108; the latest Remington’s, supra). The state of the art allows the clinician to determine the dosage regimen for each individual patient, active agent and disease or condition treated. Guidelines provided for similar compositions used as pharmaceuticals can be used as guidance to determine the dosage regiment, i.e., dose schedule and dosage levels, administered practicing the methods as provided herein are correct and appropriate.
[0231] Chemical synthesis
[0232] In alternative embodiment, methods as provided herein comprise administration of a drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5, which can comprise:
[0233] (a) a compound having the formula: (also called TAK-981), or
[0234] (b) a compound having the formula. (also called 2-D08, or 2’,3’,4'-trihydroxyflavone) or an isomer, deuterated isoform, optical isomer or stereoisomer, a racemate or racemic mixture, an enantiomer, an individual diastereomer or a diastereomeric mixture, an analog, a crystalline product or a crystalline intermediate, a pharmaceutically acceptable salt thereof, a prodrug or a bioisostere of TAK-981 or 2- D08, or 2’, 3 ’,4’ -trihydroxyflavone.
[0235] Any chemical synthesis protocol known in the art can be used to synthesize these compounds, for example, for TAK-981 as described by Langston, et al, J. Med. Chem. 2021, 64, 2501-2520; or. for 2’,3’,4'-trihydroxyflavone, as described by Kirn et al, Bioorg Med Chem Lett. 2014 Feb 15; 24(4): 1094-1097.
[0236] In alternative embodiment, the invention also provides bioisosteres of TAK- 981 or 2-D08. Bioisosteres of the invention are compounds comprising one or more substituent and / or group replacements with a substituent and / or group having substantially similar physical or chemical properties which produce substantially similar biological properties to TAK-981 or 2-D08, or racemer or isomer thereof. In one embodiment, the purpose of exchanging one bioisostere for another is to enhance the desired biological or phy sical properties of a compound without making significant changes in chemical structures.
[0237] For example, in one embodiment, one or more hydrogen atom(s) is replaced with one or more fluorine and / or deuterium atom(s), e.g., at a site of metabolic oxidation; this may prevent metabolism (catabolism) from taking place. Because the fluorine or deuterium atom is similar in size to the hydrogen atom the overall topology of the molecule is not significantly affected, leaving the desired biological activity unaffected. However, with a blocked pathway for metabolism, the TAK-981 or 2-D08 molecule may have a longer half-life or be less toxic, and the like.
[0238] In alternative embodiments, compounds used in methods as provided herein, TAK-981 or 2-D08, or a pharmaceutically acceptable salt or solvate thereof, or optical isomer thereof, or racemic mixture or enantiomer thereof; or, a pharmaceutical composition or formulation comprising TAK-981 or 2-D08, include or comprise their respective bioisosteres. In alternative embodiments, bioisosteres used to practice methods as provided herein comprise one or more substituent and / or group replacements with a substituent and / or group having substantially similar physical or chemical properties which produce substantially similar biological properties to a compound, or stereoisomer, racemer or isomer thereof. In one embodiment, the purpose of exchanging one bioisostere for another is to enhance the desired biological or physical properties of a compound without making significant changes in chemical structures.

In alternative embodiments, the AAV is engineered to increase efficiency in targeting a specific cell type that is non- permissive to a wild type (wt) AAV and / or to improve efficacy in infecting only a cell type of interest. In alternative embodiments, the hybrid AAV is retargeted or engineered as a hybrid serotype by one or more modifications comprising: 1) a transcapsidation, 2) adsorption of a bi-specific antibody to a capsid surface, 3) engineering a mosaic capsid, and / or 4) engineering a chimeric capsid. It is well known in the art how to engineer an adeno-associated virus (AAV) capsid in order to increase efficiency in targeting specific cell types that are non-permissive to wild type (wt) viruses and to improve efficacy in infecting only the cell type of interest; see for example, Wu et al., Mol. Ther. 2006 Sep;14(3):316-27. Epub 2006 Jul 7; Choi, et al., Curr. Gene Ther. 2005 Jun;5(3):299-310.
[0243] For example, in alternative embodiments, serotypes AAV-8, AAV-9, AAV-DJ or AAV-DJ / 8™ (Cell Biolabs, Inc., San Diego, CA), which have increased uptake in brain tissue in vivo, are used to deliver a nucleic acid payload for expression in the CNS. In alternative embodiments, the following serotypes, or variants thereof, are used for targeting a specific tissue:

[0250] CRISPR and Prime Editing gene therapy
[0251] In alternative embodiments, NaV1.5 K442 residue modifying nucleic acids are delivered in vivo or ex vivo or nucleic acids are altered in vivo or ex vivo using a CRISPR system such as CRISPR-Cas9 or any variants of CRISPR-Cas9. and / or a prime editing system (for example, as described in Chen, P.J., Liu, D R. Prime editing for precise and highly versatile genome manipulation. Nat Rev Genet 24, 161-177 (2023)). Similar to CRISPR, prime editing requires the presence of a Cas endonuclease and a single guide (sg) RNA. However, as the premise of prime editing is to edit sequences without generating a double-stranded break, both components are slightly modified. Instead of traditional Cas9, this method utilizes Cas9 nickase — a variant of Cas9 that nicks the DNA rather than generating double-strand breaks — fused to a reverse transcriptase. This Cas9 fusion is referred to as a prime editor (PE).
[0252] In alternative embodiments, prime editing comprises use of materials and processes as described, for example, in U.S. patent application publication nos. US 2023 / 0220374 Al; US2023 / 0357766 Al; and / or U.S patentnos. US 11,840,685 B2, US 11 ,795,452 B2; and / or as described in WO / 2021 / 072328 Al .
[0253] In alternative embodiments, prime editing comprises use of the following components: a prime editing guide RNA (pegRNA), capable of (i) identifying the target nucleotide sequence to be edited, and (ii) encoding new genetic information that replaces the targeted sequence. The pegRNA consists of an extended single guide RNA (sgRNA) containing a primer binding site (PBS) and a reverse transcriptase (RT) template sequence. During genome editing, the primer binding site allows the 3’ end of the nicked DNA strand to hybridize to the pegRNA, while the RT template serves as a template for the synthesis of edited genetic information;
[0254] - a fusion protein consisting of a Cas9 H840A nickase fused to a Moloney Murine Eeukemia Virus (M-MEV) reverse transcriptase;
[0255] Cas9 H840A nickase: the Cas9 enzyme contains two nuclease domains that can cleave DNA sequences, a RuvC domain that cleaves the non-target strand and a HNH domain that cleaves the target strand. The introduction of a H840A substitution in Cas9, through which the 840th amino acid histidine is replaced by an alanine, inactivates the HNH domain. With only the RuvC functioning domain, the catalytically impaired Cas9 introduces a single strand nick, hence the name nickase;
[0256] M-MLV reverse transcriptase: an enzyme that synthesizes DNA from a single-stranded RNA template; and a single guide RNA (sgRNA) that directs the Cas9 H840A nickase portion of the fusion protein to nick the non-edited DNA strand.
[0257] In alternative embodiments, genetic engineering ofNaV1.5 by NaVl.5 residue-modifying nucleic acids is performed in conjunction with administration of a drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5, such as a drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5 as provided herein.
[0258] In alternative embodiment the drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5 is administered first, followed by genetic engineering of NaV1.5 by NaV1.5 residue-modifying nucleic acids (for example, using CRISPR).
[0259] In alternative embodiment the drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV 1.5 is administered together (or, substantially at the same time, or substantially simultaneously) with genetic engineering of NaV1.5 by NaV1.5 residue-modifying nucleic acids (for example, using CRISPR).
[0260] In alternative embodiment the drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5 is administered after genetic engineering of NaV1.5 by NaV1.5 residue-modify ing nucleic acids (for example, using CRISPR).
[0261] In alternative embodiments, NaV1.5 K442 residue modify ing exogenous nucleic acids, Cas9, sgRNA, and associated complexes are delivered into cells such as T cells, and any vehicle for delivery can be used, for example, viral and / or non-viral systems can be used; also, electroporation of DNA, RNA, or ribonucleocomplexes can be sued; or chemical transfection techniques utilizing lipids and peptides (particularly to introduce sgRNAs can be used, optionally also in complex with Cas9 into cells); nanoparticle-based delivery for transfection, and the like can be used.
[0262] In alternative embodiments, lenti virus (LVs), adenovirus (AdV), and adeno- associated virus (AAV) are used to deliver NaV 1.5 residue-modifying nucleic acids; some categories of cells are more difficult to transfect, including stem cells, neurons, and hematopoietic cells, and these require more efficient delivery systems, such as those based on lentivirus (LVs), adenovirus (AdV), and adeno-associated virus (AAV).
[0263] In alternative embodiments, variants of CRISPR-Cas9 are used to allow gene activation or genome editing with an external trigger such as light or small molecules: including photoactivatable CRISPR systems developed by fusing light-responsive protein partners with an activator domain and a dCas9 for gene activation, or by fusing similar light-responsive domains with two constructs of split-Cas9, or by incorporating caged unnatural amino acids into Cas9, or by modifying the guide RNAs with photocleavable complements for genome editing.
[0264] In alternative embodiments, "dead" versions of Cas9 (dCas9) are used to eliminate CRISPR's DNA-cutting ability while preserving its ability to target desirable sequences. Various regulatory factors can be added to dCas9s, enabling turning any gene on or off or adjust its level of activity. Like RNAi, CRISPR interference (CRISPRi) can turn off genes in a reversible fashion by targeting, but not cutting a site. The targeted site is methylated, epigenetically modify ing the gene. This modification inhibits transcription. These precisely placed modifications may then be used to regulate the effects on gene expression (for example, HMGB2) and DNA dynamics after the inhibition of certain genome sequences within DNA.
[0265] In alternative embodiments, CRISPR-Casl3 fused to deaminases is used to direct mRNA editing; for example, Cas7-11, is better suited for therapeutic RNA editing than Casl3, and enables sufficiently targeted cuts.
[0266] In alternative embodiments, any CRISPR system can be used to practice methods as provided herein, for example, as described in US 20220387560 Al, which describes methods of treating and / or correcting ocular disease in vivo using an Adeno-associated virus (AAV) system, where the AAV system employs a nucleic acid encoding a CRISPR-Cas9 system for targeted gene disruption or correction; or US 20220389398 Al that describes using engineered CRISPR / Cas effector enzymes, such as Casl3 (Casl3d, Casl3e, or Casl3f) that maintain guide-sequence-specific endonuclease activity and lack guide-sequence-independent collateral endonuclease activity; or US 2023 0029506 Al, which describes therapeutic applications of the crispr-cas systems and compositions for genome editing; or, US 2020 0340012 Al, which describes a modular CRISPR-Cas9 architecture that allows better delivery, specificity and selectivity of gene editing; or US 8,771,945, which describes CRISPR- Cas systems and methods for altering expression of gene products; or WO 2023 283420 A2 which describes therapeutic gene silencing with crispr-casl3.

[0782] Example 1: Exemplary Methods
[0783] This example demonstrates that methods as provided can be effective for treating, ameliorating, lessening the symptoms of, or preventing: angina, myocardial infarction, reperfusion injury, a ventricular arrhythmia (VA), cardiac pump failure due to my ocardial infarction (MI) (optionally cardiac pump failure due to my ocardial infarction (MI) in an early ischemia / reperfusion (I / R) period), congestive heart failure (CHF), hypovolemia, acidosis, hyperkalemia, hypokalemia, a cardiac poisoning or cardiopathology due to a toxin or poisoning, cardiac tamponade, tension pneumothorax, coronary hrombosis, sepsis, shock, pulmonary thrombosis, pulmonary embolism, respiratory decompensation, arrythmia a cardiac event caused by hypoperfusion and / or cardiac arrest, by administering to an individual in need thereof a drug or composition capable of suppressing hypoxia-induced SUMOylation of a cardiac sodium channel NaV1.5.
[0784] Cardiac ILATEcurrent and arrhythmia. In healthy hearts, ILATEis less than 0.5% of the peak sodium current (iNa) and permeates through a small number of NaV1.5 channels that do not stay closed after inactivation (2). In patients with ischemic and failing heart, ILATEcan increase to 4%-5% of peak INa, a level we and others have also shown in subty pes of cardiac sudden infant death and long QT syndrome (3 -5). Acute hypoxia and ischemia are recognized to increase ILATEin cardiac myocytes (6-8) prior to slower processes like remodeling (18). Excess ILATEis pro-arrhythmic because it prolongs action potential duration (APD), reducing repolarization reserve, increasing susceptibility to after-depolarizations, and causing a predisposition to TdP, a ventricular dysrhythmia that is lethal when sustained, with increases in ILATEabove baseline by as little 2-fold associated with sudden cardiac death (3,5,9-11). These observations motivated studies by our group and others to investigate inhibition of late NaV1.5 re-openings with medications like mexiletine and ranolazine4,8,19 and this proposal to suppress the regulatory event that generates ILATEwith MI, hypoxia- induced SUMOylation of NaVl.5.1 SUMOylation at the PM. Among PTMs that regulate cardiac proteins (i.e., phosphorylation, acetylation, and ubiquitinoylation). Small Ubiquitin-like Modifier (SUMO) protein modification (SUMOylation) at the PM has been little studied. Present in all eukaryotic cells, the SUMO pathway, and its component enzy mes, were first identified to regulate the trafficking, activity, and lifespan of nuclear proteins, now including more than 60 transcription factors, mediating their movement between the cytosol and nucleus to control cell division. DNA repair and cellular metabolism in adaptation to environmental changes.20-22 Therefore, it was unexpected when we demonstrated the direct SUMOylation of Na+ and K+ channels in the PM of nerves and muscles to regulate excitability, showing that SUMOylation of different channel types varies (1,23-28) and that NaV1.2 in the central nervous system (CNS) neurons (28) and NaV1.5 in cardiac myocytesl show little SUMOylation at baseline but are modified within min in response to hypoxia.
[0785] Given the important role of hypoxia-induced increases in ILATEin MI morbidity and mortality, we test the hypothesis that SUMOylation of Nav1.5 channels may offer a new target for therapy. More generally, we propose to elucidate the mechanism of SUMOy lation at the PM since we have shown that SUMOylation can proceed in off-cell membrane patches, supporting the notion that the SUMO enzy me cascade is stably resident on the cytosolic face of the PM, not just at the nucleus and in the cytosol (23-25). Our studies may inform investigations of heart failure and cardiac hypertrophy where the SUMO pathway exercises its classical role in metabolic adaptation to stress (29,30). The studies is relevant to other cardiac ion channels we have shown to be SUMOylated (27) and in the CNS since we have shown SUMOylation of NaV1.2 regulates both backpropagation (31) and deleterious neuronal sodium loading with hypoxia (28).
[0786] SUMOylation of NaV1.5 is a novel therapeutic target for MI; whereas the channel has been targeted by existing medication to suppress ILATE, the drugs have significant side-effects, in some cases exacerbating arrhythmias. Here, we seek to prevent and suppress the pathology before it is fully manifest. Further, SUMOylation of PM targets to regulate excitability in health and disease is a novel strategy. The SUMO pathway has recently been identified as a therapeutic target for heart failure based on its regulation of nuclear events and cellular metabolism. Novel preliminary data. We created a KI mouse that ablates NaV1.5 SUMOylation and have preliminary data to support the hypothesis that suppressing SUMOylation of NaV 1.5 can decrease VA and, unexpectedly, ameliorate cardiac dysfunction. Moreover, we demonstrate that SUMO pathway inhibitor in phase I / II trials can inhibit Nav1.5 SUMOylation and protect WT mice subjected to LAD occlusion, therefore the study is extremely timely. The SUMO pathway and inhibitors
[0787] The SUMO pathway. Our observation that K+ and Na+ channels at the PM are subject to regulation by covalent linkage of SUMOs (1,23,24,26-28,31,34) should, perhaps, have been more readily accepted. Although the majority of vertebrate targets are nuclear transcription factors, SUMO activating, conjugating, and cleavage enzymes were first identified in the yeast X cerevisiae. including deSUMOylases (SENPs) that move near the PM at the neck between mother and daughter cells (35,36). In vertebrates, the pathway has three SUMO isoforms (SUMO -3) of approximately 100 amino acids that covalently linked to the s-amino group of specific intracellular target lysine residues to alter function (Fig 1) (37) SUMO1 is approximately 50% identical to SUMO2 and SUMO3, that differ at only 4 residues. Although SUMOylation is a covalent PTM, it is subject to reversal by SENPs 1-7, which vary in tissue distribution and roles; SENP2 / 3 are most significant to homeostasis in healthy, adult human heart (38).
[0788] SUMO pathway inhibitors. Given the role of the SUMO pathway in cellular metabolism via nuclear transcription factors, El and E2 have been targeted for the treatment of cancer. Among the emerging pharmacopeia, TAK-981, brand name SUBASUMSTAT™, selectively inhibits the El activating enzyme by forming a covalent adduct with SUMO in the catalytic site and has promising activity in preclinical models for lymphomas (2). pancreatic adenocarcinomas (3) and multiple myeloma (4), and has advanced to four phase 1 / 2 clinical trials (NCT03648372, NCT04074330, NCT04381650, and NCT04776018), showing “a manageable safety profile along with preliminary anti-tumor activity” (5,6). 2-D08 is a selective inhibitor of the E2 SUMO conjugase (Ubc9) that prevents transfer of SUMO to the target (7) and has been used to study SUMOylation in preclinical work on genome integrity (8), cancer (9,10), hepatic ischemic reperfusion injury (11), and viral replication (12,13). SUMOylation of ion channels. Since we first reported SUMO regulation of K2P 1 channels in 2005 (23) we have additionally reported SUMOylation of other K+ and Na+ channels at the PM of excitable cells, demonstrating the PTM to increase excitability by decreasing K+ flux or increasing Na+ currents, and deSUMOylation to produce the opposite effects. The SUMOylated channels we have described include K2P1; K2P1 / K2P3 and K2P1 / K2P9 (IKSO); Kv2.1; KCNQ1 / KCNE1 (IKs); NaV1.2; and, NaV1.5; in rat cerebellar granular neurons, cortical pyramidal neurons, neonatal rat cardiac myocytes, human cardiac iPS cells, and on heterologous expression (1, 23, 24. 26-28, 31, 34). SUMOylation of PM proteins has now also been described by other in the CNS,39,40 and pancreas (41).
[0789] Hypoxia-induced SUMOylation of NaV1.2 in central neurons. Seeking natural events in physiology that might regulate SUMOylation, we studied hypoxia because ground squirrels show increased SUMOylation during hibernation when tissue oxygen and glucose levels fall (42). We studied NaV1.2 in rat cerebellar granule neurons because the earliest effects of hypoxia with ischemic stroke on central neurons is an increase in sodium current (INa) and sodium loading (43-45). We observed hypoxia-induced SUMOylation of NaV1.2 channels that increased INa, and that the time-course for SUMOylation of single channels at the PM and changes in INa coincided. Mutation of a single residue (NaV1.2-Lys38) or application of a deSUMOylating enzyme prevented hypoxia-induced SUMOylation (28). The NaV1.2 channels were not SUMOylated at baseline but hypoxia led to rapid linkage of SUMO1 to almost all NaV1.2 channels at the PM, left-shifting the voltage-dependence of activation. Recently, we used CRISPR / Cas9 to create a KI mouse to replace the only SUMO- conjugation site (NaV1.2- Lys38Gln) so the channel no longer responds to hypoxia; we showed that SUMOylation of NaV1.2 in cortical pyramidal neurons exclusively controls persistent sodium current (INaP) and AP backpropagation, thereby playing a prominent role in synaptic integration and plasticity (46).
[0790] Hypoxia-induced SUMOylation of cardiac NaVl.5 and ILATE. Given the importance of hypoxia-induced ILATEin heart disease, we tested the hypothesis that SUMOylation ofNaV1.5 was an underlying mechanism. The confirmaloiy results were publishedl (Fig 2) and are summarized here briefly to rationalize the proposal and demonstrate two of the methods we would apply in this proposal. One salient feature of hypoxia- induced SUMOylation of NaV1.5 is that SUMOylation ofNaV1.5 on K442 is necessary and sufficient to explain hypoxia-induced changes in ILATEas shown by reconstitution of the response in CHO cells using whole-cell and single-channel patch clamp recording (Fig 3). This panel demonstrates an important differentiating aspect of our approach to studying SUMOylation compared to most others: we do not overexpress SUMO or SUMO pathway enzymes for days before cells are studied because these manipulations alter scores of off-target genes and secondary pathways; rather, we study live-cell responses in real-time by applying the regents to excised patches or within cells via the pipette to limit confounding effects. Thus, in Fig 3 wild-type NaV1.5 (WT) or NaV1.5- K.442Q expressed in CHO cells with NaV[31 with normoxic (21% O2) or hypoxic (1.5% O2) solution and 1 nM SUMO (red) or 1 nM SENP1 (blue) is applied via the recording pipette. In the research plan section, the same approach shows that hypoxia also induces native ILATEin hiPS-CMs in a SUMO-dependent manner.
[0791] A second key aspect of hypoxia-induced SUMOylation is that hypoxia recruits one SUMO1 to each NaV1.5 on the cell surface at the same rate as ILATEincreases; this is shown strikingly by imaging the arrival of single SUMO molecules to the PM of live cells in real-time only at sites of single NaV1.5 channels in response to hypoxia using TIRFm (Fig 4). Whole-cell current measurements show that NaV1.5 is SUMOylated in response to hypoxia at the same rate as ILATEdevelops, that SUMO is only attached to K442, as no SUMO is recruited by NaV1.5-K442Q (we also show using macroscopic FRET1), and that SUMO chains do not form, since only single SUMOs link to single WT channels).
[0792] Discovery ofTAK-981 and pharmacology in mice. Elevated levels of SUMO pathway elements are associated with poor outcomes for patients w ith some cancers.47 Agents were therefore developed to suppress SUMOylation as potential drugs. TAK-981 acts by linking covalently to the SUMO activating enzyme (SAE) component of the El enzyme when SUMO is in the catalytic site, a process called substrate-assisted inhibition. Studies ofTAK-981 with various cell types and in mice offered findings to support human trials.48, 49 Thus, treatment of pancreatic tumor cell lines for 4 h decreased SUMO conjugates in the nucleus (where the majority of SUMO conjugates reside) almost completely in a concentration dependent manner and decreased viability of the cancer cells lines; importantly, the same treatment w as well tolerated by normal VH10 fibroblasts.48 In mice, intravenous administration w as notable for decreasing SUMOylation in HCT-116 tumors after a single dose of 50 mg / kg TAK- 981 such that nuclear SUMOylation was eliminated by 4 h with SUMO-adducts measured by mass spectrometry (MS) represented approximately 80% of the El at 2 hours (h) and approximately 100% by 8 h. Of note, the pathway recovered after a single dose between 8 to 24 h in different studies consistent with lysis of the adduct or synthesis of new El. The pharmacokinetic (PK) and pharmacodynamic (PD) studies in rat were similar (where poor oral bioavailability was also demonstrated).
[0793] Conclusion: given the role of ILATEin arrhythmogenesis and our demonstration that SUMOylation of NaV1.5 is a mechanistic basis for hypoxia-induced late re- openings, we conjectured these as viable targets for therapeutic interv ention for MI- associated VA and LV dysfunction. These findings led us to create the NaV1.5- K442Q KI mouse model.
[0794] Prevention of excess ILATEbv SUMOylation inhibitors. Seeking to study SUMO inhibitors in clinically relevant manners, we first applied them in a scenario reflecting a patient with symptoms in whom vascular occlusion has not yet produced significant ischemic hypoxia nor NaV1.5 SUMOylation. Here, we applied the inhibitors for various periods (0 to 4 h) at levels we had screened to avoid toxicity prior a challenge with SUMO or hypoxia. In the first study, we raised intracellular SUMO1 to 10 nM via the recording pipette, a condition that leads to full SUMOylation of NaV1.5 within mins. As expected, we observed mean ILATEto rise from normal to pathological levels, approximately 0.4% to 3.8% (Table 1, see FIG. 20). When cells we pre-treated for 4 h to suppress El ligase function with TAK-981 (15 uM), mean ILATEdecreased to <1%. The time course for 2-D08 (20 uM) inhibition of SUMO conjugase (E2 aka Ubc9) appeared to be like TAK-981 in these preliminary studies; both agents decreased exogenous SUMO-induced ILAIE to approximately 1.5% in 2 h and this suggested that targeting both El and E2 merit study. Next, we sought to assess the inhibitors when NaV1.5 SUMOylation and excess ILATEwas induced by hypoxia (Table 2, see FIG. 20). Again, exposure to 1.5% O2led to an expected increase in ILATEfrom -0.4% to 3.8% and in these preliminary studies 4 h treatment with TAK- 981 (15 uM) or 2-D08 (20 uM) limited ILATEto approximately 2%. Because patients can also present with significant ischemia, a scenario reflecting vascular occlusion, producing NaVl .5 SUMOylation, we sought to develop an assay to study the speed of recovery' after hypoxic challenge on reperfusion. Figures 3 and 4 show that hypoxia-induced ILATEin cells in whole-cell clamp mode remains elevated when cells return to 21% O2for 3 min (the reproducible duration of such experiments being limited to approximately 10 min). We therefore confirmed that 20 min in a 1.5% O2incubator induced ILATEand the cells could be returned to 21% O2and studied for 24 h thereafter, displaying full recovery by 18 h (not shown); this leads us to propose to assess if NaV1.5 channels were deSUMOylated, if new channels were recruited to the cell surface replacing those that were SUMOylated, or both, in HEK293T cells and isolated adult murine cardiomyocytes.
[0795] The N-terminus of SENP2 and its PM location. We have shown that intracellular application of soluble SENPs leads to deSUMOylation of ion channels at the PM, 1,23, 24, 26-28, 31, 34 as have others (54). Furthermore, each of the six encoded SENPs (SENP1-3 and SENP5-7) has been visualized at the nucleus with sub-structure localization determined by their six unique N- termini (55). Thus, consistent with reports by others that the N-terminus of SENP2 mediates association with the endoplasmic reticulum and inner nuclear membranes and its deletion leads to enzyme in the cytosol (56); Fig 5 shows that in our hands WT SENP2 tagged with an mCherry fluorescent protein (SENP2-mCherry) labels the nuclear membrane and a truncation lacking just the N-terminal 18 residues (SENP2-del 18-mCherry) is seen throughout the cytosol (Fig 5), similar to a SENP2 splice variant lacking the first 50 residues (57). This demonstrates an approach we propose to apply to study the six encoded SENPs. Furthermore, we observe the N-terminal 18 residues of SENP2 carries Cysl6 within a motif for S-palmitoylation, a post-translational modification by a palmitic acid via a thioester linkage that mediates protein association with membranes, compart-mentalization in membrane subdomains, trafficking, and stability. Hypoxia-induces excess ILATEand AP prolongation in hiPS-CMs in a SUMO- dependent manner. Validating the utility of the hiPS-CMs for these studies. Fig 6 shows that hypoxia rapidly induces native ILATEin human iPS-CMs in a SUMO- dependent manner. At 21% O2, INa activated rapidly to a mean peak of 40 ± 4 pA / pF at -30 mV in whole-cell mode and then inactivated to produce a normal residual ILATEthat was 0.46% ± 0.1% of peak current. When 02 was lowered to 1.5%, mean peak INa was unchanged (42 ± 3 pA / pF), but ILATEincreased approximately 10-fold to 4.4% (1.85 pA / pF) of peak after 100 s. The magnitude of the changes in ILATEwere like those observed in tissue culture cells (Figs 3 and 4), isolated rat ventricular myocytes6 and human cardiac muscle subjected to hypoxia, approximately 4-5% over 5 -15 min (2, 58). As expected from our studies of cloned NaV1.5, SUMO1 in the pipette induced changes in native INa like those produced by hypoxia: ILATEincreased to 4.2% of peak INa without a change in the peak magnitude. With SUMO in the pipette, changing the bath from 21% to 1.5% O2did not further alter INa peak nor ILATE, supporting the conclusion that hypoxic regulation of INa proceeds via SUMOylation. Further, delivering 1 nM SENP1 into the hiPS-CMs by the pipette fully suppressed the increase in ILATEinduced by hypoxia. Of note, we deliver 1 nM SUMO 1 into cells because that level evokes maximal effects on NaV 1.2 channels in cerebellar granule neurons (CGNs) and three different K+ channels in CGNs, hippocampal neurons, and rat cardiac myocytes (26-28, 34).
[0796] By recording spontaneous APs in current-clamp mode we could show SUMO- dependent, hypoxia-induced increases ILATEled to APD prolongation to levels observed in patients with VA and sudden death (Fig 7). The changes are suppressed by ranolazine, a drug that inhibits NaV1.5 ILATE. Including half of the hypoxia-induced increase in ILATEin hiPS-CMs into the O’Hara- Rudy model for human cardiac action potentials (59) reproduced the observed pro-arrhythmic increase in APD.
[0797] We have shown that hypoxia produces pathologic levels of ILATEdue to SUMOylation of NaV1.5 channels on K4421 and demonstrate here for the first time that SUMO pathway inhibitors of E1 and E2, TAK- 981 and 2-D08, respectively, suppress SUMOylation and ILATEin vitro and VA and LV dysfunction in WT mice subjected to LAD ligation. Here, we assess the kinetics and duration of protection and the time course for recovery with two proven agents and two alternative inhibitors.
[0798] We can use whole-cell patch clamp withNaV1.5 (with NaVβ1) expressed in HEK293T cells to study (a) the dose-dependent kinetics of ILATEonset with hypoxia in absence and presence of TAK-981 and 2-D08 at various concentrations, (b) the dose- dependent kinetics of ILATEresolution with normoxic reperfusion in the absence and presence of TAK-981 and 2-D08 at various concentrations, (c) The dose- dependent kinetics of ILATEonset with hypoxia with two less studied E1 inhibitors, ML-792 and COH000, and further analyses if indicated. Despite their use only in preclinical studies, ML-792 is of interest because it is the most potent El inhibitor identified thus far and inhibits SUMOylation rapidly in vitro (60) and COH000 is reported to be selective with IC50 of 0.2 μM and a delineated molecular mechanism of action (61, 62). These studies are performed as in Figure 3.
[0799] We can first to express NaV1.5 (with NaVβ1) in HEK293T cells to study (a) the kinetics of SUMO forward transport to the PM and colocalization at sites of NaV1.5 in response to hypoxia without and with TAK-981 and 2-D08 using TIRFm, FRET, and Western Blot, (b) To determine the rate of loss of NaV1.5 from the membrane at baseline and after 20 min hypoxia without and with TAK-981 and 2-D08 via surface biotinylation and membrane protein purification with avidin at various times, followed by SDS-PAGE and NaV1.5 visualization with epitopes to polyHisl or 1D4 and HA23; whole-cell INa is measured at the time of purification to estimate the rate of restoration of new, non-biotinylated channels on the surface; (c) the rate of deSUMOylation of PM channels when delivery of new channels to the surface is suppression by cycloheximide (68). (d) Comparative studies of channel turnover can be performed and cardiomyocytes from WT and SCN5AK442Q mice using surface biotinylation / avidin purification and antibodies directed to mNaV1.5 (69, 70).
[0800] We posit that the enzy mes required to activate, mature and conjugate SUMO are present in the PM of Xenopus oocytes, tissue culture cells and neurons (1,23-28) because (1) covalent attachment is required to regulate the channels; (2) pro-SUMO can modify channels in off-cell, inside-out membrane patches and this requires maturation of the pro-protein by a SENP, as well as an El- and E2-like ligase and conjugase activities; (3) although SENPs are synthesized in the cytoplasm, the cytosol diffuses away from inside-out off-cell patches; (4) we used confocal microscopy to visualize GFP-E2 at the PM of Xenopus oocytes (23) and SAE1 , E2 and SUMO1 at the PM of CHO-K1 cells;24 and others have reported that E2 can reach the PM and co-localizes with the dopamine transporter in HEK293T cells (72).
[0801] Using on and off-cell patch recording, FRET, and TIRFm (Figures 3-6 and 1,23-28) we can confirm and expand the findings to quantify surface expression of (a) FP-tagged E1, E2, SUMO1, SUMO2 / 3, and the six encoded SENPs in HEK293T cells using TIRFm and seek evidence for co-localization withNaV1.5. (b) Validate use of commercial antibodies for SUMO pathway proteins for study of native proteins in iPS-CMs and mouse cells, (c) Study the role of the first 18 residues in the PM binding of SENP2 in HEK293T cells using the full-length and truncated SENP2 constructs for TIRF and FRET, (d) Study SENP2 C16S mutation to test our hypothesis that palmitoylation mediates PM binding, (e) Apply palmitoyl-protein thioesterase in the pipette and in inside-out patch membranes to test the hypothesis that SENP2 matures pro-SUMO and leads to the SUMOylation ofNavl.5 in HEK293T cells to uncover mechanism and for potential later use with iPS-CMs Human cardiac myocytes derived from pluripotent stem cells (iPS-CMs) are now widely used to screen for drug-induced alterations in cardiac cellular contractility', electrophysiology, and viability because they recapitulate many of the attributes of cardiac physiology. Thus, we showed hypoxia induces a rapid increase in ILATEand APD in iPS-CMs (Figure 6) to levels associated with human pathology and studying the parameters of electrical function and employing the O’Hara Rudy model for simulations, as described.1 Here, we seek to expand our prior studies to assess the effect of the SUMO inhibitors, SUMO enhancers (overexpression of SUMO + / - E2) and, if indicated palmitoyl-protein thioesterase. Current-clamp can be used to record action potentials in iPS-CMs under normoxia and hypoxia without and with TAK-981 and 2-D08 and the alternative inhibitors, ML-792 and COH000, if indicated. Second, to study intact cells, iPS-CMs genetically encoded with a fluorescent voltage indicator (as described by Chiamvimonvat (73)) can be imaged under the same experimental conditions.
[0802] After covalent attachment of SUMO, regulatory- actions are via non-covalent binding of a conserved hydrophobic groove in SUMO and hydrophobic target residues called the “SUMO interacting motif (SIM)” stabilized by charge-charge interactions (74, 75). SUMO-SIM interactions alter function directly (76, 77) and can also recruit non-SUMOylated proteins bearing SIMs into complexes with SUMOylated targets (78).
[0803] We can (a) test the 6 high-likelihood SIMs in NaV1.5 predicted by two validated tools79,80 by site-directed mutagenesis and functional assessment of ILATE; (b) identify SIM and non-SIM interactions of Navi.5 with SUMO by cross-linking mass spectrometry (XL-MS) using novel agents like Alkyne- A-DSBSO, a strategy method that allow s purification and secondary cleavage to improve MS resolution (81, 82); and (c) use molecular dynamics (MD) simulations to predict energetically important residue-residue interactions (e.g.. mutations alter AAG by > 2 kcal / mol). and confirm them by thermodynamic mutant-cycle analysis to support the structural model of the complex produced with know n structures for SUMO175 and NaV1.5 (83, 84) as we have before for complexes of the Hvl channel with Alb, and Hvl with a designed protein blocker (85, 86).
[0804] Inhibition of Nav1.5 SUMOylation and ILATEcan result in a decrease in AP prolongation, reduction in intracellular Na+ loading, prevention of the subsequent increase in intracellular Ca2+ from Na+ / Ca2+ exchanger activities, leading to a decrease in early and delayed afterdepolarization (EAD and DAD) and adverse LV remodeling post I / R. Therefore, inhibition of NaV1.5 SUMOylation represents a viable strategy to reduce VA and LV dysfunction in acute and post-acute phases of MI. We demonstrated that hypoxia produces pathologic levels of ILATEdue to SUMOylation of NaV1.5 channels on a single residue, lysine 442 (K442), and that ILATEis eliminated by mutation of the site, or by application of a deSUMOylating enzyme (1). We can take advantage of a knock-in (KI) mouse model. NaV1.5- K442Q, that we have generated. Eata demonstrate that ablation of Nav1.5 SUMOylation and hypoxia-induced ILATEresult in a significant decrease of VA and LV dysfunction compared to the WT mice. Moreover, SUMO pathway inhibitors suppress Nav1.5 SUMOylation, ILATE, ventricular arrhythmia (VA), and ameliorate LV dysfunction in WT mice subjected to I / R injury.
[0805] Figs 9-18 and (33, 91-98) support the feasibility of the techniques to quantify the arrhythmia burdens, infarct size, and systolic and diastolic function during the acute, sub-acute (2 weeks) and chronic phase (3 months) after I / R injury. Multidisciplinary techniques include ECG recordings during I / R surgeries, ambulatory ECG, ECHO, in vivo hemodynamic monitoring, histological analyses, single-cell analyses including quantification of local and global Ca2+ concentrations, and patch-clamp analyses. Here, we show the beneficial effects of ablation of SUMOylation site in Nav1.5 as well as SUMO pathway inhibitors, offering preliminary demonstration that VA and pump failure are suppressed.
[0806] NaV1.5-K442Q mice show normal systolic and diastolic function as well as heart rate compared to WT animals as assessed by echocardiography. To create the KI mice, replacing the only SUMO- conjugation site in Navl.5, we used CRISPR / Cas9 and FVB mice, a strain commonly used to study cardiac function (99-102). Briefly, Scn5AK442Q / WT heterozygous mice were generated by Biocytogen (Wakefield, MA) as follows. Two sgRNAs in introns 7 and 10 were designed with a tool from Wellcome Sanger Institute and screened for on-target activity using a Universal CRISPR Activity Assay (UCATM, Biocytogen Pharmaceuticals Co., Ltd). AT7 promoter sequence was added to the Cas9 or sgRNA template by PCR amplification. Different concentrations of donor vector and purified in vitro transcribed Cas9 mRNA and sgRNA were mixed and co-injected into the cytoplasm of one- cell stage FVB fertilized eggs. Injected zygotes were transferred into oviducts of Kunming pseudo- pregnant females to generate FO mice. PCR and sequencing verification of founder pups with the intended mutation were then crossed with wild-type (WT) mice for germline transmission, which was further confirmed by PCR, sequencing, and Southern blot analysis. Each liter is genotyped and cared for according to 1ACUC protocols. We reported an analogous strategy to create SCN2AK38Q mice, demonstrating that single SUMOylation site in NaV1.2 regulates AP backpropagation in cortical neurons playing a prominent role in synaptic integration and plasticity the CNS (46).
[0807] Echocardiography was used to determine the systolic and diastolic function in the WT and NaV1.5-K442Q mice as we have described (33, 93, 95-97). Diastolic function is assessed using the ratio of the blood flow velocities through the mitral valve during early filling (E) and late filling (A), E / A ratio, as well as deceleration time. Fig. 9 shows normal systolic and diastolic function in the KI mice compared to WT littermates. Mice is implanted with ECG transmitters. Longitudinal ambulatory ECG telemetry and echocardiographic recordings is performed every 2 weeks for up to 3 months. There were no significant differences in RR, PR intervals, QRS duration or QTc intervals at baseline between WT and KI mice.
[0808] NaVl .5-K442Q mice show protection from VA and improvement in LV dysfunction compared to WT in response to LAD ligation. To support the central hypothesis, we performed 45-minute ischemia followed by reperfusion (I / R) surgeries in WT and KI mice. Fig IOC and E show a significant decrease in VA burdens in the KI compared to the WT littermates. Moreover, at 2 weeks after I / R surgeries, WT mice show a significant decrease in left ventricular ejection fraction (LVEF) and fractional shortening (FS) compared to sham animals (Fig 11, D-E). In contrast, even though KI mice show a significant decrease in LVEF and FS compared to sham, the left ventricular function is better preserved compared to WT animals post 1 / R. To further confirm the findings, we perform hemodynamic monitoring as we have previously described (33, 98) at 2 weeks to assess changes in LV pressure, volume, developed pressure (dP / dt), end- systolic and end-diastolic volumes (Fig 12). Our exciting preliminary data show a significant preservation in cardiac function in KI mice compared to WT animals (Fig. 11).
[0809] SUMO pathway inhibitors suppress VA and improve pump function in WT mice in response to LAD ligation. Two different SUMO pathway inhibitors were used (TAK-981, an El enzyme inhibitor and 2- D08, an E2 enzyme inhibitor). WT mice were injected (IP) with either vehicle (DMSO) or TAK-981 (7.5 mg / kg, resulting in the blood level of 160 pM acutely), or 2-D08 (10 mg / kg, resulting in the blood level of 460 μM acutely). The dosage were chosen based on prior published studies (48. 49, 103-108). I / R surgeries were performed after the injection. Fig 13 shows a significant decrease in VA burdens in the mice that received SUMO pathway inhibitors during ischemia. There were VAs during reperfusion in all 3 groups of mice, but the numbers of VAs were significantly reduced in the treated mice compared to the vehicle controls (Fig. 13C and E), both during ischemia and reperfusion phases Moreover, the left ventricular function is better preserved compared to WT animals treated with SUMO pathway inhibitors post I / R (Fig. 14).
[0810] To determine VA burdens and LV dysfunction in WT and KI mice as well as SUMO pathway inhibitors after I / R injury, we can directly test the arrhythmia burdens and adverse cardiac remodeling in male and female WT and NaV1.5-K442Q KI mice at 12-16 w eeks during the acute phase, sub-acute (2 weeks), and chronic (3 months) after I / R injury (96, 98, 109) SUMO pathway inhibitors is tested in the WT animals. Multidisciplinary techniques can be used including echocardiography, hemodynamic monitoring, ambulatory ECG recordings, in vivo electrophysiologic studies (EPS), assessment of infarct size and adverse cardiac remodeling. Mice can then be sacrificed for in vitro mechanistic studies.
[0811] Echocardiography can be performed to determine the LVEF, FS, LV wall thickness, dimension and volume. Diastolic function is assessed using mitral inflow and tissue Doppler to quantify E / A ratios and isovolumic relaxation time (IVRT).
[0812] Pressure-volume (PV) analyses. Intact heart hemodynamic analysis can be performed (Millar Instruments) to record chamber volume by impedance and pressure by micromanometry (33, 110). Different parameters is assessed including LV end diastolic pressure (LVEDP). PV loops can be constructed before and during transient reduction of preload to generate specific systolic and diastolic function indexes, LV afterload (indexed by arterial elastance), ejection fraction, contractile function as assessed through load-independent parameters (maximal power index and preload recruitable stroke work), and diastolic function (LV stiffness constant, tau and peak rate of pressure decline) (Fig. 12) as we have described (33).
[0813] Quantification of arrhythmia burdens in homozygous KI mice compared to WT animals. Two complementary techniques are used. Ambulatory ECG Recordings. Implanted ETA-F20™ telemetric transmitters (DSI, St. Paul, MN) is used to obtain continuous lead II ECG recordings on awake mice. Animals are allowed to recover from the telemetry implantation for 7 days before the I / R surgeries. Telemetry recordings are performed over a total of 24-hour period with 30 min of recording for each hour over 2 consecutive days (Fig. 14). Recordings are obtained at exact time of the day and night for all animals to control for diurnal variations. Data is analyzed in a blinded manner using PONEMAH SOFTWARE SYSTEM™ (DSI). Atrial and VA is quantified. VA can include premature ventricular contractions (PVCs), couplets, triplets and non-sustained ventricular tachycardia (NSVT). ECG are analyzed for RR, PR and QTc intervals. The rate-corrected QT interval (QTc) is calculated using modified Bazett's formula (QTc = QT interval (in ms) / (RR / 100)l / 2) (111).
[0814] In vivo electrophysiologic studies (EPS). In vivo EPS are performed as we have described previously to test for arrhythmia inducibility (91, 92). Briefly, standard pacing protocols is used to determine the electrophysiologic parameters, including sinus node recovery time, atrial, AV nodal, and ventricular refractory periods and AV nodal conduction properties. Each animal can undergo an identical pacing and programmed stimulation protocol. To induce atrial and ventricular tachycardia and fibrillation, programmed extra-stimulation techniques and burst pacing is utilized as we have previously described (91, 92) (Fig. 15). Programmed right atrial and right ventricular double and triple extra-stimulation techniques is performed at 100-ms drive cycle length, down to a minimum coupling interval of 10 ms. Right atrial and right ventricular burst pacing is performed as eight 50-ms and four 30-ms cycle length trains repeated several times, up to a maximum 1-min time limit of total stimulation. Reproducibility is defined as greater than one episode of induced atrial or ventricular tachycardia. The exact same programmed stimulation protocols are used in all animals. Infarct size and adverse cardiac remodeling. Infarct size is quantified in different groups of animals as we have described using TTC stain.109 For sub-acute and chronic animals, cardiac sections is stained using antibodies against collagen la, Illa, and V. and fibronectin. Picrosirius Red and wheat germ agglutinin (WGA) stains is used to quantify the amount of collagen (96-98). Flow cytometric analyses is performed as we have described to quantify the degrees of fibrosis and cardiac fibroblast activation (96-98).
[0815] To determine the mechanisms underlying the reduction in VA and LV dysfunction by Navi.5 SUMOylation ablation or SUMO inhibitors, experiments are performed using isolated ventricular myocytes from WT and KI mice during acute, sub-acute and chronic phase. We can use two SUMO- specific inhibitors (TAK-981 and 2-D08) to directly test the effects of the inhibitors on ILATE, AP, global and local Ca2+, EAD, and DAD in WT ventricular myocytes exposed to hypoxia.
[0816] To investigate the mechanistic effects of SUMO inhibitors and ablation of Nav1.5 SUMOylation on cellular arrhythmogenic mechanisms using AP recordings and AP-clamp, we can use AP-clamp as described by (112-115) followed by sequential dissection, using internal and external solutions resembling the physiological ionic milieu. The AP waveform is applied as the command voltage onto the same cell. A specific channel blocker is added to block the current of interest, and the compensation current is recorded. GS-458967, ORM-10962, and nifedipine is used to record ILATE, Na+ / Ca2+ exchanger current (INCX), and E-type Ca2+ current (ICaL). respectively, as we have described. The current of interest is obtained by subtracting the compensation current from the baseline (112-115) AP clamp (Fig. 16) can determine if late Na+ currents (ILate) are altered in 1 / R and if NaV1.5-K442Q KI or SUMO inhibitors rescue those alterations. Complementary experiments are performed using cell-attached single channel recordings as described (116). We can quantify the open probability (Po), open and closed time of the channels (116, 117). APs are recorded using perforated patch-clamp techniques to maintain intracellular milieu as we have described to quantify EAD and DAD (116, 118-122).
[0817] To determine the mechanistic effects of Nav1.5 SUMOylation ablation or SUMO inhibitors on intracellular Ca2+. Ca2+ transients (CaT). Ca2+ sparks, and SR Ca2+ load, two complementary techniques are used to investigate the critical roles of SUMO inhibitor treatment and NaV1.5-K442Q KI on local and global Ca2+ release. IONOPTIX™ sarcomere detection (lonOptix Co) and fast Fourier transform (FFT) method (33, 95, 123) rather than Fluo-4 confocal imaging edge detection are used to measure single cardiomyocyte contraction because the latter may lose precision if the cell's ends move out of the focal plane during contraction. Contraction is measured using a high-speed camera. The sarcomere pattern is used to calculate the sarcomere length using an FFT algorithm. The fractional shortening is calculated as the percentage change in sarcomere length during contraction (Fig. 17). Simultaneous Ca2+ transients (CaT) are studied using Fura-2 dual- wavelength ratiometric method, 123 which yields absolute [Ca2+], Additional analyses of excitation- contraction (EC) coupling are performed including assessment of sarcoplasmic reticulum (SR) Ca2+ load ([Ca]SRT), Ca2+ current (ICa), and Ca2+ sparks using confocal line scan (Fig. 17).
[0818] Multimodal Second Harmonic Generation (SHG) - Two-Photon Fluorescence (TPF) microscopy. We employed SHG microscopy, a non-linear label-free technique, to directly image the sarcomeres based on the unique intrinsic property of the SUMO rod domains to generate a signal at twice the frequency and half the wavelength of the laser beam used to excite the sarcomeres (124). We utilized multimodal SHG-TPF imaging techniques to simultaneously image Ca2+ levels and sarcomere contraction at high spatial and temporal resolutions (Fig. 18) (32, 33). The method has multiple advantages: 1) it images the A-band and is independent of T- tubule morphology which varies in diseased hearts and in different cell types, and 2) it enables simultaneous measurements of microdomain contraction and local Ca2+ levels in live cardiomyocytes. Simultaneous SHG to non-invasively image the sarcomere and TPF to image the Ca2+signal is obtained in ventricular myocytes isolated from KI models (Fig. 18B). The experiments allow us to directly quantify the single sarcomere contraction and relaxation of cardiac myocytes. We can determine if alterations in local and global Ca2+ signaling, sarcomere contraction, and relaxation can be rescued with SUMO inhibitors and in the KI mouse model.
[0819] Statistical analysis: All data is tested for normality by the Shapiro-Wilk test and homogeneity of variances are assessed using Levene’s test (125). Statistical significance is determined using appropriate unpaired two-tailed Student’s t-test, nonparametric tests, one-way analysis of variance (ANOVA) or two-way ANOVA for multiple comparisons with appropriate post hoc analyses. p<0.05 are considered significant.
[0820] Methods
[0821] IV drug administration. Mice are anesthetized with inhaled isoflurane, and 40 pl of drug or drug vehicle is instilled retro-orbitally (IV) using a 27-gauge needle.
[0822] Adult mouse cardiomyocyte isolation. Before the procedure, we record the mouse body weight, strain, sex and date of birth. Heparin (200 pl) are injected intraperitoneal (i.p.) 10 min prior to anesthesia to prevent coagulation of blood in the coronary arteries. The mouse is anesthetized with ketamine and xylazine by i.p. injection (80- 120 / 5-10 mg / kg), secured in the supine position by gently fixing the forepaws and hind paws to a work surface on a surgery tray near the perfusion system. A midline skin incision from mid abdomen to the diaphragm is made and cuts bilaterally to retroflect the thoracic cage to expose the heart. The heart is lifted slightly using fine curved serrated and atraumatic forceps and dissected out of the thoracic cavity. The heart is transferred to a 100 mm dish containing cold perfusion buffer and then connected to the cannula. The heart is perfused with calcium-free perfusion buffer at flow rate of 4 ml / min for 4-5 min until the effluent becomes clear, then we switch to digestion buffer for 3.5-20 min depending on perfusion pressure and collagenase activity. Digestion is stopped when the heart becomes slightly pale and flaccid. Cells are dissociated and calcium reintroduced. Cells are collected and suspended in 5 ml plating medium. We count the total number of myocytes and percentage of rod-shaped myocytes and adjust the concentration of rod-shaped myocytes to 25.000 / ml in a 50 ml tube. Gently suspension with a 10 ml pipette is followed by aspiration of the coating solution, and plating to dishes. Dishes are placed in a CO2 incubator at 37°C for 1-3 h to allow myocyte attachment to about 80%. We gently remove unattached myocytes and cell debris and add new culture medium.
[0823] Ischemia-Reperfusion Model (I / R model): The procedure is performed as described in detail in previous publication (1-3). Ischemia-reperfusion is induced in 10-week-old male Slc26a6- / - (KO) mice and wild-ty pe (WT) littermates. The procedure is performed using aseptic techniques. The fur is removed from the surgical incision sites (Nair) and the skin cleaned with Betadine followed by 70% alcohol 3 times. Surgery is performed on a clean and disinfected lab bench, with sterilized instruments (autoclaved). Mice is placed on a sterilized cloth on a circulating water blanket to maintain body temperature. Surgeons scrub with Betadine, mask and wear sterile gloves. Animals is anesthetized with intraperitoneal ketamine 100 mg / kg and xylazine 5 mg / kg. Intubation is done perorally and mechanical ventilation is started. The procedure is performed as described in detail in previous publication.1 An oblique 8-mm incision is made 2 mm away from the left sternal border in the 4th intercostal space. The chest cavity is then opened. The chest retractor is inserted and opened gently to spread the wound 8-10 mm in width. The heart partially covered by the lung is then visualized. The pericardium is gently picked up with curved and straight forceps, pulled apart, and placed behind the arms of the retractor. The left anterior descending (LAD) coronary artery is then visualized and ligated 1-2 mm below the tip of the left auricle in its normal position, which induces roughly 40-50% ischemia of the LV. Occlusion is confirmed by the change of color of the anterior wall of the LV and is left for a period of 45 minutes after which the occlusion is removed. The retractor is removed, and the lungs are reinflated by shutting oft" the ventilator outflow as previously described. The chest cavity is then closed. The sham-operated mice undergo the same procedure without tying the suture but moving it behind the LAD artery. The chest is closed with 3-0 DEXON™ rib sutures, 5-0 DEXON II™ muscle sutures and buried skin sutures (buried continuous intradermal suture pattern with 4-0 absorbable suture). Negative plural pressure is re-established via a temporary chest tube until spontaneous breathing occurs. A bolus injection of 0.1 mg / kg of buprenorphine SC is given. Recovery (until the animal is ambulatory) includes visual monitoring of the animal for a period of 2-4 hours. Additional postoperative treatment includes supplemental buprenorphine (0.1 mg / kg) every 12 hours as an analgesic (through at least the second day) and a warm environment.
[0824] Electrocardiographic recordings: ECG recordings is performed using BIOAMPLIFIER™ (BMA 831, CWE, Incorporated, Ardmore, PA) as we have previously described4. The intraperitoneal pentobarbital 40 mg / kg is used to maintain anesthesia during recording. The animals are placed on a temperature-controlled warming blanket at 37°C. Four consecutive two-minute epochs of ECG data is obtained from each animal. Signals were low-pass filtered at 0.2 kHz and digitized using DIG1DATA 1200™ (Axon Instrument, CA). A total of 100 beats is analyzed from each animal in a blinded fashion. The Q-T interval is determined manually by placing cursors on the beginning of the QRS and the end of the T wave. The rate- corrected QT interval (QTc) is calculated using modified Bazett's formula as reported by Mitchell et al for mouse models, whereby the RR interval is expressed as a unitless ratio (RR in ms / 100 ms). QTc interval is defined as (QT interval (in ms) / (RR / 100)l / 2) (5).
[0825] Radiotelemetry ECG monitors: Mice are anesthetized with intraperitoneal ketamine 100 mg / kg and xylazine 5 mg / kg, intubated and mechanically ventilated with supplemental oxygen at a respiratory rate of 100 breaths / min and tidal volume of 0.2 ml. The fur is removed from the surgical incision sites (Nair) and the skin cleaned with Betadine followed by 70% alcohol 3 times. Surgery is performed on a clean and disinfected lab bench, with sterilized instruments (autoclaved). Mice is on a sterilized cloth on a circulating w ater blanket to maintain body temperature. Surgeons scrub with Betadine, mask and w ear sterile gloves. A sterile ECG transmitter (Data Sciences International. volume=2.1 cc and weight=3.4 g) is implanted to monitor heart rate. A 10-mm incision is made in the abdomen and the sterile transmitter placed within the peritoneal cavity and is secured to the inside wall of the abdomen with non- absorbable sutures. The two ECG leads is tunneled subcutaneously and tied to right shoulder and xyphoid space caudal to the ribcage. The abdominal muscle is closed with 6-0 Nylon sterile sutures and the skin is closed with 4-0 absorbable sutures (Ethilon). The whole procedure should take about 15-20 minutes. A bolus injection of 0.1 mg / kg of buprenorphine SC is given. Recovery (until the animal is ambulatory) includes visual monitoring of the animal for a period of 2-4 hours. Additional postoperative treatment includes supplemental buprenorphine every 12 hours as an analgesic (through at least the second day) and a warm environment. Post-operative records is kept in the housing room, noting the condition and date of PI inspection. The mice is allowed to recover for at least 7 days, at which point, 24 hour of non- invasive telemetry is recorded. Ischemia-reperfusion or sham surgery is performed and monitoring is continued for up to 6 weeks.
[0826] In vivo Electrophysiologic Studies: In vivo electrophysiologic studies is performed as we have previously described (4). All surgical procedures follow the UC Davis Guidelines for Aseptic Surgical Technique. Intraperitoneal pentobarbital 40 mg / kg is used to maintain anesthesia during surgery which is expected to last -30-45 minutes. A small skin incision of 3-5 mm. is made on the right side of the neck. Right jugular vein is dissected under direct visualization under dissecting microscope and catheter inserted. A special 1.7 French octapolar catheter with an interelectrode spacing of 0.5 mm (CIBER MOUSE EP™, NuMed, Hopkinton, NY) is used via right jugular vein into the right atrium and right ventricle.
[0827] Pacing protocols is performed via the catheter under anesthesia. Standard pacing protocols is used to determine the electrophysiologic parameters, including sinus node recovery time, atrial, AV nodal, and ventricular refractory periods and AV nodal conduction properties. Pacing is performed through the catheter using an external stimulator (Bloom stimulator). Sinus node recovery time is measured between the last paced atrial depolarization and the first sinus return cycle after 15 second of atrial pacing at several pacing cycle lengths (CL).
[0828] AV nodal conduction properties is obtained by atrial and ventricular incremental pacing methods until Wenckebach Periods are defined such as 2: 1 AV block or retrograde ventriculoatrial block. Atrial, AV, and ventricular effective refractor) period (ERP) is analyzed by the extra-stimulus method. Each animal undergoes an identical pacing and programmed stimulation protocol.
[0829] To induce atrial and ventricular tachycardia and fibrillation, programmed extra-stimulation techniques and burst pacing is utilized. Programmed right atrial and right ventricular double and triple extra-stimulus techniques is performed at 150-ms drive cycle length, down to a minimum coupling interval of 10 ms. Right atrial and right ventricular burst pacing is performed as eight 50-ms and four 30-ms cycle length trains episodes repeated several times, up to a maximum 1-min time limit of total stimulation. Carbachol (a muscarinic receptor agonist, 50-100 ng / g i.p.) is administered during the pacing protocol to further assess atrial arrhythmias inducibility as previously described above. For comparison of the inducibility in each animal, programmed extra- stimulus techniques and stimulation duration of atrial and ventricular burst pacing is kept uniformly in all animals. Reproducibility is defined as greater than one episode of induced atrial or ventricular tachycardia. All the animals remain under anesthesia for the catheter placement and the pacing procedures. Noninvasive echocardiographic imaging: Cardiac function in the I / R animals is assessed using noninvasive imaging with echocardiogram in conscious state as we have previously described4. The chest is shaved. The animal is placed in a supine position on a warming blanket (37). The mice are restrained in a 50 ml conical tube with an opening for the nose and chest, this is a standard procedure for imaging mice for this kind of study. The imaging generally lasts for 5 minutes. We can determine the fractional shortening, left ventricular wall thickness, dimension and volume. Diastolic function is assessed using mitral inflow and tissue Doppler imaging (TDI).6 Altered patterns of valve annulus motion can be early indicators of diastolic dysfunction. Hemodynamic Monitoring: Hemodynamic monitoring is performed as previously described using AD instrument. The animals is injected with pentobarbital i.p. (40-80 mg / kg) to achieve surgical anesthesia. Intact heart hemodynamic analysis is performed using a four-electrode PV catheter (Millar Instruments) to record chamber volume by impedance and pressure by micromanometry: 7 Different parameters is assessed including left ventricular (LV) end diastolic pressure (LVEDP). PV loops is constructed before and during transient reduction of preload to generate specific systolic and diastolic function indexes, LV afterload (indexed by arterial elastance), ejection fraction, contractile function as assessed through load-independent parameters (maximal power index and preload recruitable stroke work), and diastolic function (LV stiffness constant, tau and peak rate of pressure decline (dP / dtmin)) (8). All animals are euthanized 3 weeks after the surgery. Intraperitoneal pentobarbital 40- 80 mg / kg is used to achieve surgical anesthesia. The chest is opened via a midline thoracotomy. Exsanguination can occur upon removal of the heart. The animals are expected to develop compensated cardiac hypertrophy at 3 weeks with no clinical detectable sign or symptoms and can develop early decompensated heart failure at 6 w eeks at which time the animals can develop sign and symptoms of heart failure including decreasing appetite, and weight gain.
