Research-use context: This article is provided for laboratory research and educational purposes only. It is not medical, therapeutic, diagnostic, veterinary, dosing or human-use guidance.
A defined tetrapeptide
Epitalon, also written Epithalon, is the tetrapeptide Ala-Glu-Asp-Gly (AEDG). Its compact sequence makes exact molecular definition important when reviewing research material and literature.
Cellular and telomere-associated research
Experimental literature has examined Epitalon in models involving gene regulation, telomerase activity and telomere biology. Recent cell-line research reported changes in telomere length associated with telomerase upregulation or alternative lengthening mechanisms.
Interpretation requires restraint
Cell-line and preclinical observations are not equivalent to demonstrated human outcomes. VOREVIA presents this literature as research context rather than therapeutic or longevity guidance.
