A synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, studied for its telomerase-activating, anti-aging, and pineal gland regulatory properties.
Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews|2026|Rahman O, Lee S, Seeds W
Therapeutic peptides are emerging as promising adjuncts in the management of orthopaedic injuries, grounded in their ability to modulate molecular signaling networks central to cellular medicine. By acting on key pathways such as PI3K/Akt, mTOR, MAPK…
