Attorney Docket No. 63578-716601OLIGONUCLEOTIDE-MEDIATED KNOCKDOWN OF RENAL OUTER MEDULLARY POTASSIUM CHANNEL (ROMK)CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 697,295 filed on September 20, 2024, the entirety of which is incorporated herein by reference.INCORPORATION BY REFERENCE OF SEQUENCE LISTING

[0002] The present application is being filed along with a Sequence Listing in electronic format. The Sequence Listing is provided as a file entitled 63578-716 601 SL. xml, created September 18, 2025, which is 17,040,705 bytes in size. The information in the electronic format of the Sequence Listing is incorporated herein by reference in its entirety.BACKGROUND

[0003] The renal outer medullary potassium channel (ROMK) is a weak inward rectifying K+ channel with a key role in renal K+ recycling and secretion (Ho et al., Nature, 1993, 362, 31-38; Shuck et al., The Journal of Biological Chemistry, 1994, 269(39), 24261-24270; Lee and Hebert, American Journal of Physiology -Renal Physiology, 1995, 268(6), Fl 124-F1131 ; Lu et al., The Journal of Biological Chemistry, 2002, 277, 37881-37887; and Hebert et al., Physiological Reviews, 2005, 85:319-371). In the thick ascending limb (TAL) of a nephron, ROMK channel activity provides the K+ gradient necessary for Na and Cl reabsorption by the Na+-K+-2C1- (NKCC2) co-transporter. In the distal convoluted tubule (DCT) and cortical collecting duct (CCD), ROMK channels form the major secretory pathway for K+ and as a result, play an important role in K+ homeostasis under physiological conditions (Welling and Ho, American Journal of Physiology -Renal Physiology, 2009, 297(4): F849-F863).

[0004] Inhibition of ROMK channel activity can result in natriuresis, diuresis, and reduced blood pressure. Therefore, ROMK inhibition may offer a novel mechanism of blood pressure regulation and diuresis in patients suffering from hypertension, congestive heart failure or any other edematous disease conditions. Inhibition of ROMK may produce diuretic efficacy that is equivalent to or better than currently available loop diuretics and with potentially lower incidence of hypokalemia. In some instances, inhibition of ROMK may benefit the patients that are resistant to loop diuretics.Attorney Docket No. 63578-716601SUMMARY

[0047] Provided herein are oligonucleotides for inhibiting the expression of ROMK. In some embodiments, the oligonucleotide comprises an antisense strand substantially complementary to a sequence encoding ROMK (e.g., sequence of an RNA produced from KCNJ1). In some embodiments, the antisense strand comprises at least 14 contiguous nucleotides substantiallyAttomey Docket No. 63578-716601 complementary to the sequence of nucleotides encoding ROMK (e.g., RNA produced from KCNJ1), with no more than 4 mismatched nucleotides.

[0048] The term “antisense strand” refers to an oligonucleotide having a nucleotide sequence substantially complementary to a target sequence in a transcript, e.g., an mRNA encoding ROMK such as an RNA produced from the gene KCNJ1. In embodiments wherein the oligonucleotide is an RNAi agent, the term antisense strand may be used interchangeably with the term “guide strand”.

[0049] The term “sense strand” refers to an oligonucleotide having a nucleotide sequence substantially complementary to an antisense strand, e.g., the antisense strand of an RNAi agent herein. The term “sense strand” may be used interchangeably with the term “passenger strand.”

[0050] As used herein, and unless otherwise indicated, the term “complementary,” when used to describe a first nucleotide sequence in relation to a second nucleotide sequence, refers to the ability of an oligonucleotide comprising the first nucleotide sequence to hybridize and form a duplex structure under certain conditions with an oligonucleotide comprising the second nucleotide sequence, as will be understood by the skilled person.

[0051] The terms “complementary,” “completely complementary” and “substantially complementary” herein can be used with respect to the base matching between the antisense strand of an oligonucleotide, e.g., an RNAi agent, and a target sequence, or between the sense strand and the antisense strand of an RNAi agent, as will be understood from the context of their use. Complementary sequences, e.g., between an antisense strand and a target sequence in a target transcript, or between the sense and antisense strand of an siRNA, include base-pairing of the oligonucleotide or polynucleotide comprising a first nucleotide sequence to an oligonucleotide or polynucleotide comprising a second nucleotide sequence over the entire length of one or both nucleotide sequences. Such sequences can be referred to as “completely complementary” with respect to each other when there are 0 mismatched base pairs upon hybridization of the two sequences. However, where a first sequence is referred to as “substantially complementary” with respect to a second sequence herein, the two sequences can be completely complementary, or they can form one or more, but generally not more than 5, 4, 3, 2, or 1 mismatched base pairs upon hybridization for a duplex up to 30 base pairs, while retaining the ability to hybridize under the conditions most relevant to their ultimate application, e.g., inhibition of gene expression via a RNA-induced silencing complex (RISC) pathway. However, where two oligonucleotides are designed to form, upon hybridization, one or more single stranded overhangs, such overhangs shall not be regarded as mismatches with regard to the determination of complementarity. For example, an siRNA comprising one oligonucleotide 21 nucleotides in length and another oligonucleotide 19 nucleotides in length, wherein the longerAttorney Docket No. 63578-716601 oligonucleotide comprises a sequence of 19 nucleotides that is fully complementary to the shorter oligonucleotide, can yet be referred to as “completely complementary” for the purposes described herein.

[0052] “Complementary” sequences, as used herein, can also include, or be formed entirely from, non-Watson-Crick base pairs or base pairs formed from non-natural and modified nucleotides, in so far as the above requirements with respect to their ability to hybridize are fulfilled. Such non-Watson-Crick base pairs include, but are not limited to, G:U Wobble or Hoogsteen base pairing.

[0053] If an RNA sequence is recited using deoxyribonucleotides, any thymidines (“T”s) can be replaced with uridines (“U”s) or uridine analogs to convert the DNA sequence to an RNA sequence.

[0054] In some embodiments, the oligonucleotide comprises an antisense strand comprising at least 14 contiguous nucleotides substantially complementary to a sequence of nucleotides within a transcript encoding ROMK (e.g., RNA produced from KCNJ1). In some embodiments, the antisense strand has no more than 5 mismatched nucleotides to the sequence of nucleotides within the transcript encoding ROMK. In some embodiments, the antisense strand has no more than 4 mismatched nucleotides to the sequence of nucleotides within the transcript encoding ROMK. In some embodiments, the antisense strand has no more than 3 mismatched nucleotides to the sequence of nucleotides within the transcript encoding ROMK. In some embodiments, the antisense strand has no more than 2 mismatched nucleotides to the sequence of nucleotides within the transcript encoding ROMK. In some embodiments, the antisense strand has no more than 1 mismatched nucleotides to the sequence of nucleotides within the transcript encoding ROMK. In some embodiments, the antisense strand is completely complementary to the sequence of nucleotides within the transcript encoding ROMK (e.g., 0 mismatches).

[0063] In some embodiments, the oligonucleotide is an RNAi agent or RNAi trigger for inhibiting expression of ROMK. As used herein, an “RNAi agent” or “RNAi trigger” refers to an oligonucleotide molecule capable of inducing RNA interference (RNAi), which mediates the targeted cleavage of an RNA transcript via an RNA-induced silencing complex (RISC) pathway. The RNAi agents disclosed herein include but are not limited to: short (or small) interfering RNAs (siRNAs), double stranded RNAs (dsRNA), micro RNAs (miRNAs), short hairpin RNAs (shRNA), and dicer substrates (e.g., DsiRNAs).

[0064] In some embodiments, the RNAi agent is a double stranded RNA molecule comprising an antisense strand and a sense strand that are complementary to one another and hybridize to form a duplex or double stranded region. One strand of the RNAi agent, the antisense strand or guide strand, includes a region of complementarity to a target sequence in a nucleic acid encoding ROMK (e.g., RNA produced from KCNJ1). The other strand, the sense strand or passenger strand, includes a region that is complementary to the antisense strand, such that the two strands hybridize and form a duplex structure when combined under suitable conditions. In some embodiments, the double stranded RNA molecule may be formed by base pairing between two separate molecules of RNA (e.g., an antisense strand and a sense strand). In some embodiments, the double stranded RNA molecule is a self-complementary molecule formed by intramolecular base pairing between two separate regions of a single RNA molecule (e.g., an antisense region linked to a sense strand through an unpaired RNA linker forming a loop or hairpin loop).

[0065] Where the two strands are part of a self-complementary molecule, the connecting RNA chain is referred to as a “hairpin loop.” A hairpin loop can comprise at least one unpairedAttorney Docket No. 63578-716601 nucleotide. In some embodiments, the hairpin loop can comprise at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 23 or more unpaired nucleotides or nucleotides not directed to the target site of the dsRNA. In some embodiments, the hairpin loop can be 10 or fewer nucleotides. In some embodiments, the hairpin loop can be 8 or fewer unpaired nucleotides. In some embodiments, the hairpin loop can be 4-10 unpaired nucleotides. In some embodiments, the hairpin loop can be 4-8 nucleotides. In some embodiments, the hairpin loop can contain 1-4 oligoethyne glycols, including ethylene glycol, di ethylene glycol, triethylene glycol, tetraethylene glycol, hexaethylene glycol, or any combination thereof.

[0066] Where the two substantially complementary strands of a double stranded RNA molecule comprise separate RNA molecules, those molecules need not, but can be covalently connected. In certain embodiments, where the two strands are connected covalently by means other than an uninterrupted chain of nucleotides between the 3 ’-end of one strand and the 5 ’-end of the respective other strand forming the duplex structure, the connecting structure is referred to as a “linker” (though it is noted that certain other structures defined elsewhere herein can also be referred to as a “linker”). The RNA strands may have the same or a different number of nucleotides. The maximum number of base pairs is the number of nucleotides in the shortest strand of the double stranded RNA molecule minus any overhangs that are present in the duplex

[0067] In some embodiments, the RNAi agent is an siRNA.

[0068] In some embodiments, the RNAi agent is a shRNA.

[0069] In some embodiments, the RNAi agent is a dicer substrate (e.g., a Dicer- substrate siRNA).

[0070] In some embodiments, the sense and antisense strands of the dsRNA are each independently about 15 to about 30 nucleotides in length, or about 25 to about 30 nucleotides in length, e.g., each strand is independently between 15-29, 15-28, 15-27, 15-26, 15-25, 15-24, 15- 23, 15-22, 15-21, 15-20, 15-19, 15-18, 15-17, 18-30, 18-29, 18-28, 18-27, 18-26, 18-25, 18-24,18-23, 18-22, 18-21, 18-20, 19-30, 19-29, 19-28, 19-27, 19-26, 19-25, 19-24, 19-23, 19-22, 19- 21, 19-20, 20-30, 20-29, 20-28, 20-27, 20-26, 20-25, 20-24,20-23, 20-22, 20-21, 21-30, 21-29, 21-28, 21-27, 21-26, 21-25, 21-24, 21-23, or 21-22 nucleotides in length.

[0071] In some embodiments, the duplex structure is between 15 and 30 base pairs in length, e.g., between, 15-29, 15-28, 15-27, 15-26, 15-25, 15-24, 15-23, 15-22, 15-21, 15-20, 15-19, 15- 18, 15-17, 18-30, 18-29, 18-28, 18-27, 18-26, 18-25, 18-24, 18-23, 18-22, 18-21, 18-20, 19-30,19-29, 19-28, 19-27, 19-26, 19-25, 19-24, 19-23, 19-22, 19-21, 19-20, 20-30, 20-29, 20-28, 20- 27, 20-26, 20-25, 20-24,20-23, 20-22, 20-21, 21-30, 21-29, 21-28, 21-27, 21-26, 21-25, 21- 24, 21-23, or 21-22 base pairs in length.Attorney Docket No. 63578-716601

[0083] In some embodiments, the antisense strand consists of a nucleotide sequence of any one of SEQ ID NOs: 477-952, or any one of SEQ ID NOs: 477-952 or 2065-2219, and the sense strand consists of a nucleotide sequence of any one of SEQ ID NOs: 1-476, or any one of SEQ ID NOs: 1-476 or 1910-2064.

[0084] While a target sequence is generally about 15-30 nucleotides in length, there is wide variation in the suitability of particular sequences in this range for directing cleavage of any given target RNA. Various software packages and knowledge within the art provide guidance for the identification of optimal target sequences for any given gene target, but an empirical approach can also be taken in which a “window” or “mask” of a given size (as a non-limiting example, 21 nucleotides) is literally or figuratively (including, e.g., in silico) placed on the target RNA sequence to identify sequences in the size range that can serve as target sequences. By moving the sequence “window” progressively one nucleotide upstream or downstream of an initial target sequence location, the next potential target sequence can be identified, until the complete set of possible sequences is identified for any given target size selected. This process, coupled with systematic synthesis and testing of the identified sequences (using assays as described herein or as known in the art) to identify those sequences that perform optimally can identify those RNA sequences that, when targeted with an RNAi agent, mediate the best inhibition of a target protein expression (e.g., ROMK) or a target gene expression (e.g., KCNJ1). Thus, while the sequences described herein represent effective target sequences, it is contemplated that further optimization of inhibition efficiency can be achieved by progressively “walking the window” one nucleotide upstream or downstream of the given sequences to identify sequences with equal or better inhibition characteristics.

[0085] It is contemplated that for any sequence identified, e.g., any one of SEQ ID NOs: 1 - 1904, or any one of SEQ ID NOs: 1-1904 or 1910-2552, further optimization could be achieved by systematically either adding or removing nucleotides to generate longer or shorter sequences and testing those sequences generated by walking a window of the longer or shorter size up or down the target RNA from that point. Again, coupling this approach to generating new candidate targets with testing for effectiveness of RNAi agents based on those target sequences in an inhibition assay as known in the art and / or as described herein can lead to further improvements in the efficiency of inhibition. Further still, such optimized sequences can be adjusted by, e.g., the introduction of modified nucleotides as described herein or as known in the art, addition or changes in overhang, or other modifications as known in the art and / or discussed herein toAttorney Docket No. 63578-716601 further optimize the molecule (e.g., increasing serum stability or circulating half-life, increasing thermal stability, enhancing transmembrane delivery, targeting to a particular location or cell type, increasing interaction with silencing pathway enzymes, increasing release from endosomes) as an expression inhibitor.

[0086] An ROMK RNAi agent described herein can contain one or more mismatches to the target sequence. In some embodiment, an ROMK RNAi agent as described herein contains no more than 4 mismatches (e.g., no more than 4, 3, 2, 1, or 0 mismatches to the target sequence). If the antisense strand of the RNAi agent contains mismatches to a target sequence, it may be preferable that the area of mismatch is not located in the center of the region of complementarity. If the antisense strand of the RNAi agent contains mismatches to the target sequence, it may be preferable that the mismatch be restricted to be within the last 5 nucleotides from either the 5’- or 3’-end of the region of complementarity. For example, for a 21 nucleotide RNAi agent, the strand which is complementary to a region of a nucleic acid sequence encoding ROMK (e.g., RNA produced from KCNJ1) generally does not contain any mismatch within the central 11 nucleotides. The methods described herein or methods known in the art can be used to determine whether an RNAi agent containing a mismatch to a target sequence is effective in inhibiting the expression of ROMK. Consideration of the efficacy of RNAi agents with mismatches in inhibiting expression of a target gene is important, especially if the particular region of complementarity in a target gene is known to have polymorphic sequence variation within the population.

[0087] In some embodiments, any one of the RNAi agents described herein can reduce expression levels of ROMK. In some embodiments, reduction in expression levels is assayed using an ROMK reporter construct encoding ROMK. The skilled artisan will appreciate that various approaches to generating a reporter construct for assessing RNAi agent activity may be used in the art, including commercially available kits, e.g., the psiCHECK-2 vector (Promega). In some embodiments, any one of the RNAi agents described herein can reduce expression levels of an ROMK reporter (e.g., a nucleic acid encoding ROMK) when assayed in cultured cells. Any suitable cells known in the art may be used to assess the RNAi agents. In some embodiments, the cultured cells are Hepal-6. In some embodiments, administration of any one of the RNAi agents disclosed herein to a cultured cell results in a reduction in expression level of ROMK. In some embodiments, administration of the RNAi agent results in at least a 55% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least a 60% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least a 65% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least aAttorney Docket No. 63578-71660170% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least a 75% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least an 80% reduction in expression levels of the ROMK reporter. In some embodiments, administration of the RNAi agent results in at least an 85% reduction in expression levels of the ROMK reporter.

[0146] A set of siRNAs were designed to target nucleic acids encoding ROMK such as the RNA produced from KCNJ1 (shown here as SEQ ID NOs: 1905-1909). A detailed list of the unmodified siRNA sense and antisense strand sequences is shown in Table 1 A below (with T representing uracil in the RNA sequences). A detailed list of modified siRNAs is shown in Table IB below. Table 2 provides abbreviations of modified nucleotides used in the nucleic acid sequences herein. Oligonucleotides are chemically synthesized using phosphoramidite approach and after quality control using UV- and mass-spectroscopy, sense and antisense strands were annealed to perform screening

[0147] RPTEC / TERT1 cells are plated at a density of about 5,000 cells / well in 100 uL each of complete DMEM:F12 (10% FBS, with hTERT RPTEC Growth Kit additives) 4 days prior to transfection. Media is changed by replacement with 100 uL fresh complete media. On the day of transfection (4 days after plating), cells are confirmed to be adherent by visual inspection and media is changed to 80 uL of fresh complete media. Transfection is done by dose diluting the siRNA in OptiMEM, then adding an equal volume of OptiMEM and constant RNAiMax (0.3 uL / reaction) to each transfection, final concentration is 10 nM for screening (1 pmol / 100 uL). The transfected cells are incubated at 37°C in an atmosphere of 5% CO2.

[0148] Inhibition of ROMK will be assessed by measuring transcript level in cell lyzates using branched DNA reaction following standard manufacture protocols

[0149] HEK cells are plated at a density of about 5,000 cells / well in 100 uL each of complete RPMI (10% FBS, 20 mM L-glutamine, 10 mM HEPES pH 7.2, 1 mM sodium pyruvate, lx MEM non-essential amino acidswith) 4 days prior to transfection. Media is changed by replacement with 100 uL fresh complete media. On the day of transfection (4 days after plating), cells are confirmed to be adherent by visual inspection and media is changed to 80 uL of freshAttorney Docket No. 63578-716601 complete media. Transfection is done by dose diluting the siRNA in OptiMEM, then adding an equal volume of OptiMEM and constant RNAiMax (0.3 uL / reaction) to each transfection, final concentration is 10 nM for screening (1 pmol / 100 uL). The transfected cells are incubated at 37°C in an atmosphere of 5% CO2. siRNA and psiCHECK2-ROMK plasmid transfection is carried out by adding siRNA duplexes, psiCHECK2-ROMK plasmid, and Lipofectamine 2000 to each well. The psiCHECK2-ROMK plasmid comprises a nucleic acid sequence for expression of the protein ROMK. Opti-MEM media is used to adjust the transfection mix to a final siRNA concentration of 10 nM, 5 nM, 2.5 nM, 1.25 nM, 0.625 nM, 0.3125 nM, 0.1563 nM, 0.0781 nM, 0.0391 nM, or 0.0195 nM.

[0150] 24 hours after transfection, Firefly (transfection control) and Renilla (fused to full-length ROMK luciferase are measured. First, media is removed from cells. Then, Firefly luciferase activity is measured by adding a volume of DUAL-GLO® Fuciferase Reagent equal to the culture medium volume to each well. The mixture is incubated at room temperature for 30 minutes before luminescence (500 nm) is measured to detect the Firefly luciferase signal. Renilla luciferase activity is measured by adding DUAL- GLO® STOP & GLO® Reagent to each well and the plates are incubated for 10-15 minutes before luminescence is again measured to determine the Renilla luciferase signal. The DUAL-GLO® STOP & GLO® Reagent, quenches the firefly luciferase signal and sustains luminescence for the Renilla luciferase reaction. siRNA activity is determined by normalizing the Renilla ROMK signal to the Firefly (control) signal within each well. The magnitude of siRNA activity is then assessed relative to cells that were transfected with the same vector but were not treated with siRNA or were treated with a nontargeting siRNA.Example 2: ROMK siRNA Design and Evaluation

[0151] A set of siRNAs were designed to target nucleic acids encoding ROMK such as the RNA produced from KCNJ1 (shown here as SEQ ID NOs: 1905-1909). A detailed list of the unmodified siRNA sense and antisense strand sequences is shown in Table 1 A below (with T representing uracil in the RNA sequences). A detailed list of modified siRNAs, along with the data for their mRNA activity and IC50, is shown in Table IB below. Table 2 provides abbreviations of modified nucleotides used in the nucleic acid sequences herein. Oligonucleotides were chemically synthesized using phosphoramidite approach and after quality control using UV- and mass-spectroscopy, sense and antisense strands were annealed to perform screening.

[0152] Hepal-6 cells (ATCC, CRL-1830) were maintained by biweekly passing in DMEM GlutaMAX (ThermoFisher, 10569) supplemented with 10% heat-inactivated FBS (Sigma,Attorney Docket No. 63578-716601F4135) (DIO). Hepal-6 cells were purchased and cultured as per the manufacturer's handling guidelines to generate frozen stocks in heat-inactivated FBS supplemented with 10% DMSO. Each aliquot of cells was thawed using a 37 °C water bath for 5 minutes, and cells were transferred and quenched using DIO in 50 mL conical. Cells were then pelleted by centrifuging at 300 x g for 5 minutes, spent media was aspirated, and cell pellet was resuspended to appropriate density and seeded for continuous culture.

[0153] One day prior to transfection, Hepal-6 cells were dissociated using IX TrypLE™ Express Enzyme (ThermoFisher, 12605010) and seeded into solid white 96-well TC plates (ThermoFisher, 136102) at 30,000 cells / well in 100 pL of D10. 96-well plates were stored overnight in a 37 °C, 5% CO2 incubator.

[0154] On the day of transfection, dual transfection of siRNA and plasmid DNA were performed. siRNA and psiCHECK2-ROMK plasmid transfection was carried out by adding siRNA duplexes, psiCHECK2-ROMK plasmid, and Lipofectamine 3000 to each well. The psiCHECK2-ROMK plasmid (Promega, C8021) comprises a nucleic acid sequence for expression of the protein ROMK and Renilla luciferase.

[0155] Before the transfection, individual siRNA at 5 uM were diluted into OptiMEM to make a high dose. 1 :3 Serial dilutions were prepared in 96-well plates for the following doses 3, 1, 3.33X 10’1, 1.11 x 101, 3.70X 10’2, 1.23x l0’2, 4.12xl0’3, 1.37x l0’3, 4.57x l0’4, 1.52x l0’4, 5.08x 10’5, 1.69xl0’5nM. A negative control containing IX phosphate buffered saline (PBS), OptiMEM, and RNAiMax were also prepared following the top dose calculations. Plasmid DNA transduction master mixes were prepared as per manufacturer’s protocol, where a Lipofectamine 3000 mix (L3) was prepared by adding 0.2 pL / well of Lipofectamine 3000 (ThermoFisher, L3000075) to 5 pL / well of OptiMEM media (ThermoFisher, 31985062). The P3000 enhancer reagent master mix (P3) was prepared by adding 100 ng / well of plasmid DNA and P3000 enhancer reagent at 0.2 pL / well to 5 pL / well of OptiMEM media. Subsequently, L3 and P3 master mixes were combined 1 : 1 to make the L3P3 master mix and incubated at room temperature for 25 minutes. During the incubation for L3 and P3, a master mix of Lipofectamine RNAiMax (ThermoFisher, 13778150) at 0.05 pL / well and OptiMEM 30pL / well was created. 30 pL of RNAiMax master mix was added to each diluted siRNA well for a total of 60 pL per preparation well and allowed to incubate at room temperature for 15 minutes.

[0156] Post-25-minute incubation of L3P3, previously plated cells were removed from the incubator. The spent media was aspirated and replaced with 40 pL of fresh warm OptiMEM. 10 pL of L3P3 master mix was then added to each well by multichannel pipetting. Immediately following L3P3 addition and post- 15 -minute incubation, 50 pL of siRNA+RNAiMax mixes were added to the appropriate replicate wells following the plate map. Following additions ofAttorney Docket No. 63578-716601 both L3P3 and siRNA+RNAiMax master mixes, the cell plates were placed into a 37 °C, 5% CO2 incubator.

[0157] 24 hours after transfection, Firefly (transfection control) and Renilla (fused to full-length ROMK) luciferase were measured. First, an appropriate amount of Dual-Glo Luciferase (Promega, El 960) kits containing Luciferase Assay Reagent II (LARII) and Stop-&-Glo (S&G) reagents were thawed and prepared as per manufacturer’s instructions and a IX passive lysis buffer (PLB) (Promega, El 941) was prepared from a 5X stock for 20 pL per well. The plates containing cells were removed from the 37 °C, 5% CO2 incubator, and the spent media was aspirated and 20 pL of IX PLB was added to each well. Plates were then placed on a digital microplate shaker (Corning, CLS67804) at 800 rpm for 15 minutes at room temperature. Postshaking, the lysed cell plates were transferred to +4 °C storage while readouts were captured. Then, Firefly luciferase activity was measured by adding DUAL-GLO® Luciferase Reagent kit (Promega, E1960) containing Luciferase Assay Reagent II (LARII) and STOP & GLO® (S&G) reagents to each well. A Synergy Hl multimode plate reader (Agilent, 8041000N) equipped with dual injectors was used to dispense LARII and S&G, capture and read luminescence. 100 pL of LARII reagent was dispensed per well and the luminescence was captured. Following LARII reagent dispense, 100 pL of S&G was dispensed per well and the second luminescent readout was captured. The DUAL-GLO® STOP & GLO® Reagent works by quenching the firefly luciferase signal and sustaining luminescence for the Renilla luciferase reaction. siRNA activity was determined by normalizing the Renilla ROMK signal to the Firefly (control) signal within each well. The magnitude of siRNA activity was then assessed relative to cells that were transfected with the same vector but were not treated with siRNA or were treated with a nontargeting siRNA.

[0158] Determination of ICso for siRNA: ICso values as shown in Table IB were determined by plotting the percentage of target gene depletion against the logarithm of siRNA concentrations. A sigmoidal dose-response (variable slope) curve was fitted to the data using the Curve Fitting function in GraphPad Prism (version 10.2.3). The ICso value was defined as the siRNA concentration resulting in 50% gene knockdown.Attorney Docket No. 63578-716601
