Approach: Lab in action. Palette: D, bold color field.

A gloved hand holds a clear petri dish at a slight low angle, close and slightly above eye level, against a saturated tomato-red backdrop. Inside the dish, a thin, translucent layer of pale pink culture medium holds a faint, lacy web of fibroblast cells, with a few small clusters just visible. Hard, clean studio light from the upper left throws a crisp curved shadow of the dish onto the red surface and picks out bright highlights on the rim and the glove's matte white nitrile. In the soft-focus background, a rack of empty microcentrifuge tubes stands out in cool white. One tiny electric green cap on a single tube adds a small accent. The mood is precise and skeptical: a promising result still confined to the dish.

Epitalon je aktivirao telomerazu u ćelijama — ali ne i kod ljudi

BY HELIX WARD · 16. окт 2026.

Mali peptid sastavljen od četiri aminokiselinske jedinice navodno je aktivirao telomerazu, enzim koji većina odraslih ljudskih ćelija drži u tišini, i produžio telomere u ljudskim ćelijama u kulturi. Ovaj rezultat je podstakao hype oko Epitalona i njegove moguće uloge u dugovečnosti, ali eksperiment je izveden na fetalnim fibroblastima, a ne na ljudima. Evo šta studija iz 2003. zaista pokazala, šta izostavlja i kako da je protumačite pre nego što odlučite da ga kupite.
