Such modulation can be employed for a variety of healthcare related applications, including but not limited to increasing the health and / or lifespan of a subject. BACKGROUND
[0005] Aging is a natural process that involves morphological and functional changes in cellular and extracellular components leading to a progressive decline in most biological functions. The process of aging is influenced by a variety of factors, including genetics, lifestyle, and aspects of the environment. The decline of cellular function due to aging causes a gradual loss of physiological functions and increased susceptibility to a host of diseases, including cardiovascular diseases, cancer, neurodegenerative disorders, Type II diabetes, and infectious and non-infectious diseases, which negatively affect the quality of human life.

In the figures, each identical or nearly identical component illustrated is typically represented by a single numeral. For purposes of clarity, not every component is labeled in every figure, nor is every component of each embodiment of the invention shown where illustration is not necessary to allow those of ordinary skill in the art to understand the invention.
[0021] FIG.1A and 1B. A) is a bar graph showing the effect of various drug treatment (T1-T11) on aging human organoids. Normal, human bronchial epithelial cells were used to generate the organoids for each of FIGS 1-4. The first bar in each sample represents the total number of organoids. The second bar represents the number of regenerated organoids produced after treatment. B) presents a table of the drug treatment compositions used in the experiment
[0022] FIG. 2. Shows images of organoids, and the chemical induction of regeneration in the aging organoid tissue. Fifteen new organoids were regenerated in the drug treatment group, while none were regenerated in the control group. Organoids typically exhibit senescence around day 40.

Without treatment, the cell population typically experiences 15 population doublings before senescence, and exhibits a doubling time of 24-48 hours. Senescence is typically reached in about 20-30 days. Vmem Sensitive FLIM Dye – BeRST: longer lifetimes = depolarization; shorter lifetimes = hyperpolarization.
[0028] FIG. 8. Aging keratinocytes increasingly depolarize. Variability is the highest (day 17 and 20) prior to most depolarized state (day 27). Without wishing to be bound by theory, this may be a senescence transition period. Variability is lower on day 40 than on day 11.
[0029] FIG.9. Provides graphs showing that ouabain treatment causes depolarization except on day 27, where the cells are already at their most depolarized state. Variability is consistent with the date shown in FIG 8. Graphs represent day 11, 15, 17, 20, 27 and 40. The top graphs indicate Vmem fold change. The bottom graphs show variance.
[0030] FIG. 10. Provides results of K-mean cluster analysis which shows moderate clustering, and that neighboring cells appear to have more similar Vmem than distant cells. Images and data represent results from day 11, day 17, day 34 and day 40. On each image, the x-axis is labeled “Centroid_X”, each y-axis is labeled “Centroid_Y”, and each axis includes values of 0, 100, 200, 300, 400, and 500.
[0031] FIG.11. Bioelectricity in cells and non-neural cell groups. (A) Highly adaptable cells such as embryonic, stem, and cancer cells tend to have a relatively depolarized state, whereas mature and fully differentiated cells are hyperpolarized (data from
[0020] ). (B) The process of developmental bioelectricity involves ion channel proteins on cell surfaces, which contol the movement of ions and establish a resting potential (Vmem) across the membrane. This cell Vmem can also be communicatedAtty. Dkt. No.166118.01474 to other cells through electric synapses, or gap junctions. The resulting interactions between cell voltages lead to stable distributions of Vmem across tissues, as seen in the frog embryo face, where they determine the placement and number of craniofacial organs like eyes and mouth. These gradients can be manipulated using interventions that target ion channels, gap junctions, and small molecular signals like neurotransmitters.
[0032] FIG. 12A and 12B. A) Morphoceuticals discovery for aging. One possible approach to altering the bioelectrical patterns associated with diseases involves utilizing transcriptomic databases to identify potential ion channel targets within a particular tissue. This information can then be utilized as an input into a bioelectrical model to simulate the resulting bioelectrical pattern after intervention, which can be further analyzed to determine candidate drugs capable of moving the current bioelectrical state towards the desired pattern.

B) HCN2 expression during aging in different tissue (GTex data sorted by descending ‘beginning minus’ end absolute value); the heatmap of genetic expression is sorted by age (X axis, 20-70 years) and by tissue (Y-axis).
[0034] FIG. 14A and 14B. A) Illustrative image showing voltage imaging of intestinal tissue harvested from Drosophila melanogaster. Intestinal tissue was harvested from control flies (young and old) and flies (young and old) engineered to overexpress HCN2 in intestinal tissue. The bioelectric pattern in the harvested tissue was analyzed by voltage imaging. B) Bioelectric sharpness (Moran’s I) in young control flies, old control flies, young HCN2-overexpressing flies, and old HCN2- overexpressing flies. In control flies, sharpness was reduced in older flies, as compared to younger flies (P-value: 0.01).

[0045] As used herein, the terms “treat,” “treating,” “treatment” and the like refer to administration of a therapy which results in the slowing, alleviation, arrest, or reversal of one or more symptoms of a disease or condition of a subject in need of such treatment. A treated subject need not be fully “cured,” the disease or condition or symptom need not be fully arrested or alleviated to be considered “treated”. Any reduction, or any decrease in advance, of a sign or symptom exhibited by the subject is considered “treated”.
[0046] As used herein, the “administration” of an agent or drug to a subject includes any route of introducing or delivering to a subject a compound to perform its intended function. Administration can be carried out by any suitable route, including orally, intranasally, parenterally (intravenously, intramuscularly, intraperitoneally, or subcutaneously), rectally, or topically. Administration includes self-administration and the administration by another. It is also to be appreciated that the various modes of treatment or prevention of medical conditions as described are intended to mean “substantial’, which includes total but also less than total treatment or prevention, and wherein some biologically or medically relevant result is achieved. The language “provided to” or “administered to” are used interchangeably herein.
[0047] As used herein, the term “effective amount” or “pharmaceutically effective amount’ or “therapeutically effective amount of a composition, is a quantity sufficient to achieve a desiredAtty. Dkt. No.166118.01474 therapeutic and / or prophylactic effect, e.g., an amount which results in the prevention of, or a decrease in, the symptoms associated with a disease that is being treated. The amount of a composition of the invention administered to the subject will depend on the type and severity of the disease and on the characteristics of the individual, such as general health, age, sex, body weight and tolerance to drugs. It will also depend on the degree, severity and type of disease. In some embodiments, an effective amount is an amount sufficient to modulate bioelectric signaling and / or bioelectric pattern.

[0050] The term “cognitive function” is used to describe an endeavor or process by a patient or subject that involves thought or knowing. The diverse functions of the association cortices of the parietal, temporal and frontal lobes, which account for approximately 75% of all human brain tissue, are responsible for much of the information processing that goes on between sensory input and motor output. The diverse functions of the association cortices are often referred to as cognition, which literally means the process by which we come to know the world. Selectively attending to a particular stimulus, recognizing and identifying these relevant stimulus features and planning and experiencing the response are some of the processes or abilities mediated by the human brain which are related toAtty. Dkt. No.166118.01474 cognition. Compounds, compositions, and methods of treatment the present disclosure may be used to enhance cognition or reduce impairment of cognitive function. Methods of testing and documenting cognitive function in a subject are well-known in the art and include, without limitation, assessments of memory, problem solving / cognitive flexibility, and / or reaction time, such as the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Mini-Cog, Alzheimer's Disease Assessment Scale - Cognitive (ADAS-Cog), Trail Making Test (TMT), and the Rey Auditory Verbal Learning Test (RAVLT). By evaluating cognition in a subject over time, impairment or improvement of cognitive function can be determined.

[0052] As used herein “Vmem” refers to membrane potential and relates to the voltage of one cell.
[0053] As used herein, “bioelectric pattern” refers to the spatial distribution of Vmem across many cells and relates to a multicellular phenomenon.
[0054] As used herein, “modulating bioelectric signaling” or “modulating a bioelectric pattern” referrers to altering Vmem by altering the membrane potential of multiple cells. Membrane potential can be modulated toward depolarization, polarization, or hyperpolarization. Modulation of the bioelectric signals results in modulation of a bioelectric pattern of multiple cells, such as in culture, in a tissue, in a cell collective, in an organ, or in an organism.
[0055] As used herein, the term “cell collective” refers to a group of cells capable of interacting to exhibit coordinated behavior and / or action.
[0056] Bioelectric Patterns, Disease, and Aging
[0057] Reference is made to Pio-Lopez and Levin (Aging as a morphostasis defect: a developmental bioelectricity perspective. doi.org / 10.31219 / osf.io / wkhx4, June 9, 2023), which is incorporated herein by reference in its entirety.
[0058] Maintaining order at the tissue level is crucial throughout the lifespan, as failure can lead to diseases such as cancer and an accumulation of molecular and cellular disorders. The most consistentAtty. Dkt. No.166118.01474 and pervasive result of these failures is aging, which is characterized by the progressive loss of function and decline in the ability to maintain anatomical homeostasis and reproduce. This leads to organ malfunction, diseases, and ultimately death. The traditional understanding of aging is that it is caused by accumulation of molecular and cellular damage resulting from energy metabolism and mitochondrial function, and that cell growth and lifespan are limited by replicative senescence due to shortening of telomeres.
[0059] Strategies to delay and potentially reverse the aging process have recently been explored and include blood factors, metabolic manipulations, senolytics, and cellular reprogramming. Methods and compositions are disclosed herein, which underlie, are intertwined with, or dovetail with each of the above explored strategies. The disclosed methods and compositions may be useful not only to alleviate many of the impacts of aging on quality of life, but also to treat and alleviate numerous disease and disorders common in the aging human population, such as cancer and cognitive impairment.
[0060] Bioelectric controls, such as voltage-sensitive channels, implement feedback loops that can break spatial symmetry and negative feedback for robustness. In addition, gap junctions (electrochemical synapses) enable bioelectric signals to be sent between cells in response to voltage and other ionic parameters, allowing for tissue-level feedback loops that respond to changes in large- scale patterns. These characteristics facilitate the precise orientation, scaling, and shaping of organs during embryogenesis, regeneration, and remodeling, through dynamic long-range coordination and anatomical decision-making. Specifically, it has been argued that these methods work because evolution exploits bioelectrical interfaces endogenously for modular control of anatomical homeostasis and repair processes. Using molecular-genetic and pharmacological techniques, researchers have been able to manipulate the distribution of voltage gradients to effect alternative anatomical structure / location during development, increase regeneration after injury, and cancer suppression. They have been able to induce the growth of entire organs from different types of tissue, change the direction of primary body axes, initiate regeneration of tails and limbs in non-regenerative conditions, alter the shape of regenerating heads in planaria to resemble those of different species, and convert oncogene-induced tumors into normal tissue. A variety of tools from behavioral and cognitive neuroscience have been harnessed for the control of tissue-level and organ-level information, which enables pushing much of the complexity onto the system itself via simple triggers. This top-down methodology for controlling anatomy opens promising avenues for therapeutic approaches to rejuvenation and the diseases of aging if we take the view that aging is a defect of morphostasis - a gradual drift from effective maintenance of anatomical homeostasis.Atty.

[0061] Developmental bioelectricity refers to signaling among non-excitable cells mediated by endogenous electricfields and differences in resting potential. These electric states arise due to specific ion channels and pump proteins, which uphold voltage gradients across the cell membrane. Such gradients elicit various cellular responses, including transcriptional and epigenetic responses (see FIG. 11B). Ion channels are selectively permeable; they differentiate between the electrical charge and size of ions, allowing movement of specific ions, such as K+, Na+, Ca2+, or Cl−, in one direction through their pore. Theflow of ions across membranes and the resulting changes in the bioelectrical pattern play a crucial role in many cellular processes, including muscle contraction, nerve signaling, secretion, tissue growth, cell proliferation and apoptosis. Ion channels play a critical role in the control systems of embryonic development and have been linked to several channelopathies of embryonic embryogenesis, which are disorders caused by mutations in ion channel genes. These conditions have been well-studied in various animal models such as fruitflies, zebrafish, mice, frogs, and human patients, implicating several ion channels, such as the potassium channel Kir2.1, and gap junctions (connexins). This research has helped to better understand the underlying mechanisms of these disorders and the role of ion channels in normal embryonic development. In addition, dysregulation of ionic gradients can contribute to age-related declines in physiological function and dysfunction of ion channels is often linked to organ failure during aging. Because of their central role, bioelectric signals are a popular target for induction of organ formation and regeneration.
[0062] Together, the voltage states induced by the action of channels, pumps, and gap junctions create a network of bioelectrical activity throughout the tissue, which ultimately triggers changes in gene expression and cell behavior (migration, differentiation, shape change, proliferation, apoptosis, etc.) that lead to specific morphogenetic outcomes. This bioelectric code translates patterns of voltage into information about organ size, shape, and positioning through mechanisms such as neurotransmitter gating, calcium signaling, and voltage-sensitive phosphatases. Analogous to the way electrical neural networks of the brain control muscle movement for behavioral goals, the ancient bioelectric networks of the body control cell activities to achieve morphogenetic outcomes, by storing and implementing gradually changing anatomical patterns.
[0063] Bioelectric control of single-cell function and differentiation
[0064] The state of Vmem in a cell and its neighbors is crucial in regulating cell behavior, along with other modes of signaling (see FIG. 11A). Usually, quiescent and differentiated cells exhibit strong polarization, while embryonic, stem, and tumor cells tend to be depolarized. However, many cells, much like neurons, have several Vmem values, with a unique set of voltage domains over their surface. Although the functional significance of voltage microdomains is yet to be determined, VmemAtty. Dkt. No.166118.01474 regulation is being employed in bioengineering to control cell connectivity differentiation, and wound healing.
[0065] Changes in Vmem are involved in controlling differentiation and proliferation in various cell types, including human mesenchymal stem cells, cardiomyocytes, iPSCs, vascular muscle, embryonic stem cells, myoblasts, as well as in neurotransmitter specification in the developing nervous system and heart. This implication of Vmem in migration, differentiation and proliferation is well- established. Crucially, the key role of bioelectricity extends far beyond the single cell state and underlies its control of large-scale order in regeneration, developmental defects, and disorders such as cancer.
[0066] Bioelectric control of large-scale anatomy
[0067] The dynamics of bioelectric signaling within the body play a crucial role in regulating diverse processes including wound healing, the formation of neural circuits, eye development, facial patterning, brain and tail size, and the determination of left-right and anterior-posterior body axis.
[0068] Manipulation of bioelectrical patterns has emerged as a promising approach for controlling morphogenesis and advancing regenerative medicine, especially because it offers the potential of using a high-level interface where simple signals can serve as triggers of complex, downstream self- limiting cascades that do not have to be micromanaged by the bioengineer. These interventions can be implemented at various levels, such as using electrotaxis to control cell movement in wound healing or by manipulating ion channels using different types of drugs known as morphoceuticals to establish specific bioelectric prepatterns for organogenesis or appendage induction. (See FIG.12).
[0069] Studies have demonstrated that malformations caused by mutations and teratogens can be reversed by enforcing the correct voltage maps using drugs, optogenetics, or channel misexpression. Additionally, profound defects in brain structure and function caused by teratogens can be reversed by restoring normal endogenous voltage pre-patterns in Xenopus.
[0070] Bioelectric signaling has also been found to be a viable method for inducing the regrowth of entire body parts. Studies on rats have demonstrated that limb regeneration can be enhanced through the use of bioelectric signals. Additionally, in a frog model of tail regeneration, complete regrowth of muscle, spinal cord, blood vessels, and skin has been observed subsequent to one-hour treatment with an ionophore, which induces a pro-regenerative state in the wound and does not need to be maintained during the subsequent regeneration process.
[0071] These bioelectrical networks in the tissues store the target morphology and coordinate cellular activity across distances. Because a cell’s bioelectric state is influenced by prior experiences, extracellular signaling, and signals from neighboring cells, these post-translational events areAtty. Dkt. No.166118.01474 invisible to traditional omics approaches. While complicating modeling and experimentation, this historicity property offers a unique target for biomedicine: reprogrammability.
[0072] Characteristics of aging cells with respect to Vmem
[0073] The inventors have previously shown that reinforcing the sharp bioelectric prepatterns resolves a variety of birth defects in frog embryos. The inventors hypothesize that resistance of the body to aging (small-scale morphogenesis that needs to happen throughout lifespan to resist progressive degradation) also requires a sharp bioelectric prepattern. The inventors hypothesize that if the prepattern is sharpened in the same way as was done for frog embryos, other organisms could exhibit longer healthspan, as well as resistance to carcinogens, teratogens, and the normal wear-and- tear of life.
[0074] Thus, the inventors propose to use genetic (DNA, RNA) or chemical (small molecule drugs) openers of ion channels, and in particular, a channel called HCN2, which due to its voltage-sensitive nature is a context-sensitive enhancer of bioelectric differences - a sharpen filter for bioelectric prepatterns. The inventors propose to use HCN2 proteins from different species (or functional variants or fragments thereof), to enhance healthspan, lifespan, and overall resistance to anything that undermines the target morphology of the body.
[0075] As shown in FIGS 7-10, aging human cells experience a change of Vmem, exhibit greater range of Vmem variance, and lose responsivity to stimuli. Regarding spatial dynamics, neighboring cells exhibit similar Vmem as compared to distant cells, and thus exhibit a clustering effect. As shown in the figures, aging cells undergo depolarization, and likely exhibit the greatest variance in Vmem when undergoing senescence. While both the youngest and oldest cells are able to respond to ouabain treatment as exhibited by depolarization, cell that are at their most depolarized state show no response.
[0076] Hyperpolarization Activated Cyclic Nucleotide Gated Potassium and Sodium Channels
[0077] Research has shown that developmental defects in the brain caused by mutations in key neurogenesis genes, such as Notch, can be rescued by the overexpression or activation of native HCN2 (hyperpolarization-activated cyclic nucleotide-gated) channels. As voltage-regulated ion channels, HCN2 channels are sensitive to their context, increasing hyperpolarization in slightly polarized cells but having no effect on depolarized cells, thus functioning as ”contrast enhancers” that sharpen weakened differences in Vmem across compartment boundaries, similar to how a sharpenfilter emphasizes order in a fuzzy image. In these studies, application of the HCN2 opener drugs was systemic, without the need to precisely control the spatial properties of delivery.
[0078] Hyperpolarization-activated cyclic nucleotide-modulated (HCN) ion channels generate electrical rhythmicity in both specialized neuron and cardiomyocytes by evoking the pacemakerAtty. Dkt. No.166118.01474 current Ih (If, Iq). The primary activating stimulus for HCN channels is hyperpolarization of the plasma membrane, as proceeding in the repolarization phase of the action potential. In addition to this primary stimulus, sympathetic activity enhances the activation of HCN channels by the second messenger cAMP, binding to the channels. The resulting increase of the pacemaker current by cAMP binding evokes an acceleration of electrical rhythmicity. Four types of HCN channels have been described: HCN1, HCN2, HCN3, and HCN4. Of these, HCN2 and HCN4 are the main types expressed in heart. The presence of both hHCN2 and hHCN4 mRNAs in cardiac tissues raises the possibility that the two channels may form heteromeric complexes in vivo. HCN2 is primarily expressed in platelets, the frontal cortex, the spinal cord, and the retina. Increased expression of HCN2 has been reported in NSC Lung Cancer NCI-H460.

[0080] In animal models, HCN2-deficient animals can be easily distinguished from their wild-type littermates because they are hypoactive and show a wide-based, ataxic gait. Electroencephalogram recordings coupled with video analyses clearly demonstrated that mutants suffer from absence epilepsy and sinus node dysfunction. Deletion of HCN2 in mice results in a cardiac phenotype. Mutants exhibit sinus arrhythmia characterized by varying RR intervals but otherwise unchanged electrocardiogram (ECG) parameters (PQ-, QRS-, QT-intervals). The same arrhythmia occurs in mice with cardiomyocyte-specific deletion of HCN2, ruling out the possibility that the phenotype has its origin in neuronal defects. Surprisingly, the deletion of HCN2 has no effect on heart rate. Mutant mice are neither bradycardic at rest nor have any impairment in speeding up heart rate during exercise or after administration of β-adrenergic agonists. These results indicate that HCN2 is not required for modulating basal as well as stimulated heart rate. In contrast, deletion of HCN4 in mice results in embryonic death. A separate study reported that HCN2 channels are a key determinant of myelin sheath length in the CNS. Reduction of HCN2 function via pharmacological blockade or generation of transgenic mice with two independent oligodendrocyte-specific HCN2 knock-out strategies reduced myelin sheath length. Researchers also reported that the lack of HCN2 facilitates the spontaneous occurrence of oscillatory activity in thalamocortical synaptic networks.

[0084] The Inventors evaluated HCN2 expression during aging, in different human tissue. Data is shown in the heatmaps provided in FIG. 13A-B. Tissues evaluated included brain (cerebellum, caudate (basal ganglia), hippocampus, putamen (basal ganglia), substantia nigra, cerebellar hemisphere, hypothalamus, nucleus accumbens (basal ganglia), cortex, anterior cingulate cortex (BA24), spinal cord (cervical c-1), amygdala, and frontal cortex (BA9)), heart (left ventricle and atrial appendage), skin (sun exposed (lower leg), and not sun exposed (suprapubic)), testis, esophagus (muscularis, and mucosa), pituitary, adrenal gland, colon (sigmoid), and transformed fibroblast cells. Age of the tissue evaluated ranged from 20-70 years.
[0085] The effect of HCN2 overexpression was tested in model organism Drosophila melanogaster (Example 1). In female individuals overexpressing the HCN2 protein, greater mean longevity was exhibited (FIG.5). Only 50% of the wild-type females were alive after 50 days, while more than 80% of the HCN2 overexpressing females were alive at the same time point. More than 75% of the HCN2 overexpressing females were alive at 57 days as compared to less than 50% of the wild-type females. However, overexpression in male fruit flies had no apparent effect (FIG 6). The effect of intestinal tissue-specific HCN2 overexpression was also assessed in Drosophila melanogaster (Example 2;Atty. Dkt. No.166118.01474 FIGS. 14A and 14B). In control flies, sharpness was reduced in older flies, as compared to younger flies (P-value: 0.01). Sharpness in old HCN2-overexpressing flies was increased, as compared to both old control flies (P-value: 0.0008) and young HCN2-overexpressing flies (P-value: 0.01).
[0086] The effect of ion channel openers was also tested on human organoid tissue with respect to anti-aging. As shown in FIGS. 1-4, gabapentin, lamotrigine, and compositions comprising these compounds elicited organoid regeneration as opposed to senescence. Treatment resulted in regeneration of young healthy organoids from old, decaying organoids.

[0164] All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
[0165] Preferred aspects of this invention are described herein, including the best mode known to the inventors for carrying out the invention. Variations of those preferred aspects may become apparent to those of ordinary skill in the art upon reading the foregoing description. The inventors expect a person having ordinary skill in the art to employ such variations as appropriate, and the inventors intend for the invention to be practiced otherwise than as specifically described herein. Accordingly, this invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.
[0166] The following examples are illustrative and should not be interpreted to limit the scope of the claimed subject matter. EXAMPLES Example 1: Effect of HCN2 overexpression on lifespan
[0167] The effect of HCN2 overexpression on aging was tested in model organism Drosophila melanogaster. Flies were engineered to systemically overexpress HCN2, and fly lifespan was measured. In female individuals overexpressing the HCN2 protein, greater mean longevity was exhibited (FIG.5). Only 50% of the wild-type females were alive after 50 days, while more than 80% of the HCN2 overexpressing females were alive at the same time point. More than 75% of the HCN2 overexpressing females were alive at 57 days as compared to less than 50% of the wild-type females. However, overexpression in male fruit flies had no apparent effect (FIG 6). Example 2: Effect of HCN2 overexpression on bioelectric pattern
[0168] The effect of tissue-specific HCN2 overexpression was also assessed in Drosophila melanogaster, using flies engineered to overexpress HCN2 in intestinal tissue (FIGS.14A and 14B). Intestinal tissue was removed from young and old flies and analyzed by voltage imaging to calculate a measure of bioelectric sharpness (Moran’s I). In control flies, the Moran’s I was significantly lower in the tissue harvested from old flies as compared to young flies (P-value: 0.01), indicating a disruption / blurring of bioelectric patterns. Interestingly, the old HCN2-overexpressing fliesAtty. Dkt. No.166118.01474 demonstrated a restoration in bioelectric sharpness (P-value: 0.008 vs. old control flies). Additionally, the bioelectric sharpness in old HCN2-overexpressing flies was significantly higher than that in young HCN2-overexpressing flies (P-value: 0.01). Without wishing to be bound by a particular theory, this finding suggests that HCN2 expression may have a varied effect on bioelectric sharpness at different stages of an organism’s lifespan. Example 3: Creation of Tissue Specific, Drug Inducible Expression of HCN2 in Transgenic Mice that will be Crossed to Existing Transgenic Mice
[0169] To create a transgenic mouse with tissue specific, drug inducible expression of HCN2, CRISPR mice with floxed HCN2 and CRISPR / Cas9 gene editing will be generated. This mouse will be mated with tissue-specific Cre transgene mice with a mutation Estrogen receptor (ER) that binds to Tamoxifen. The progeny of the mated mice will carry the Cre transgene along with unactivated HCN2. Cre expression will be induced by Tamoxifen binding to mutated ER, resulting in removal of a stop codon and expression of HCN2 in the organ of interest (e.g., liver, brain, or ovaries). Mice with tissue-specific Cre are commercially available (e.g., Charles River).
[0170] Induction of tissue-specific expression will occur once treated with Tamoxifen, allowing for observation of the effects of HCN2 at various aging stages, from young pups to older mice that more closely reflect old age. Assessment will include, (1) induction of HCN2 expression at about 6 months, to observe the effect on older mice, (2) induction immediately after birth to assess the impact on young mice, and (3) induction of organ-specific expression in one mouse, followed by surgical removal of the HCN2-expressing organ for transplantation into a second mouse. The HCN2 transgenic mice will also be mated with mice used in models of aging, obesity, Alzheimer’s, Parkinson’s, and / or diabetes.
