Epithalon: Telomerase Activation Research Guide

Epithalon (also Epitalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly (AEDG), developed from pineal gland extract research. It has become one of the most studied anti-aging peptides. Molecular Formula: C₁₄H₂₂N₄O₉ Molecular Weight: 390.35 Da A 2003 study demonstrated that Epithalon reactivates telomerase in telomerase-negative human fetal fibroblasts, leading to: - Approximately 33% telomere elongation - Extended cell proliferation beyond the Hayflick limit - Upregulation of hTERT (human telomerase reverse transcriptase) - Telomeres are protective DNA caps (TTAGGG repeats) at chromosome ends - They shorten with each cell division, leading to cellular senescence - Telomerase is normally silenced in adult somatic cells but active in stem cells Molecular studies show Epithalon: - Preferentially binds H1.3 and H1.6 histones - Remodels chromatin structure to restore "youthful" gene expression patterns - Activates ribosomal genes and neuronal differentiation markers Research in primate models shows: - Restoration of melatonin production in aged subjects - Normalization of circadian rhythms (melatonin and cortisol) - Potential sleep architecture improvements Epithalon increases: - Superoxide dismutase (SOD) - Glutathione peroxidase - Glutathione-S-transferase - Reduces oxidative stress and chromosome aberrations | Model | Observation | |-------|------------| | Mice (SHR strain) | 12-13% maximum lifespan increase | | Rodents | Extended lifespan under constant illumination | | Drosophila | Increased lifespan | | Rhesus monkeys | Restored circadian hormone rhythms | Long-term observational studies have examined: - Telomere length changes in elderly populations - Visual function in retinal conditions - Cardiovascular outcomes in coronary patients Epithalon affects 5 of the 12 recognized hallmarks of aging: 1. Telomere attrition → telomerase activation 2. Epigenetic alterations → chromatin remodeling 3. Oxidative stress → antioxidant enzyme upregulation 4. Immune dysregulation → T-cell modulation 5. Circadian disruption → pineal gland activation Note: This compound is for research purposes only.
