Epitalon

Molecular Information

Research Summary

Epitalon is derived from the research of Russian scientist Professor Vladimir Khavinson, who studied pineal gland peptides for decades. The peptide has been investigated in cell culture systems for its ability to activate telomerase, the enzyme responsible for maintaining telomere length in dividing cells. In animal models, research has demonstrated effects on lifespan extension, melatonin production, and cellular senescence markers. Epitalon represents a key compound in the study of peptide-mediated telomere biology and aging processes.

Mechanism of Action

Epitalon activates telomerase (the enzyme responsible for adding telomeric repeats to chromosome ends) in human somatic cell cultures. It modulates pineal gland melatonin production in animal models, influences antioxidant enzyme expression, and has demonstrated effects on chromatin condensation and gene expression patterns associated with cellular aging in in-vitro systems.

Published Animal Studies

• [1]Chronic administration in aging rodent models showed significant effects on melatonin production and circadian rhythm normalization (Khavinson et al., 2003)
• [2]Longitudinal studies in mice demonstrated improved physiological biomarkers of aging with chronic administration (Anisimov et al., 2003)
• [3]Rodent studies showed modulation of antioxidant enzyme levels and reduced oxidative damage markers (Khavinson et al., 2006)
• [4]Studies in aging rats demonstrated improved immune function parameters and thymic tissue preservation

In-Vitro Research

• •Human fetal fibroblast cultures demonstrated activation of telomerase and extension of replicative lifespan beyond Hayflick limit (Khavinson et al., 2004)
• •Retinal pigment epithelial cell studies showed telomerase activation and delayed senescence markers
• •Gene expression profiling showed modulation of senescence-associated genes in treated cell cultures
