Humanin, a naturally occurring micro-peptide, stands out for being encoded within mitochondrial DNA—an exclusive genetic segment present solely within mitochondria. Its primary function involves serving as a cytoprotective agent, safeguarding cells against apoptosis (programmed cell death) by disrupting the typical functions of the Bcl2-associated X protein (Bax). Variants of humanin have been identified across various mammals, exhibiting a high degree of conservation among different species[1]. Scientific investigations emphasize the significance of humanin in shielding neurons, cardiac tissue, muscle cells, the eye’s retina, and the endothelial lining of blood vessels.
