Humanin is a 24-amino acid mitochondrial-derived peptide (MDP) encoded by a small open reading frame within the mitochondrial 16S ribosomal RNA gene (MT-RNR2). First discovered in 2001 as a neuroprotective factor, humanin belongs to the novel class of mitochondria-derived peptides and represents the first peptide identified to be encoded by mitochondrial DNA. The peptide can be translated both in the mitochondrial matrix (producing a 21-amino acid variant) and the cytosol (producing the full 24-amino acid peptide), with both forms being biologically active. Humanin functions as a signaling molecule with cytoprotective and antiapoptotic properties, exerting beneficial effects across multiple organ systems including the brain, heart, skeletal muscle, and vascular tissues. Research has demonstrated humanin's role as a regulator of both lifespan and healthspan, with levels naturally declining with age and in various disease states including Alzheimer's disease, diabetes, and cardiovascular disorders. The peptide exerts its effects through multiple mechanisms including binding to cell surface receptors (FPRL1/2 and trimeric CNTFR-α/gp130/WSX-1 complex), intracellular protein interactions (BAX, IGFBP3), and modulation of key signaling pathways (STAT3, AMPK, ERK1/2). The highly potent S14G-humanin analog (HNG) shows 1000-fold greater biological activity than native humanin. While extensive preclinical evidence supports humanin's therapeutic potential for age-related diseases, neurodegenerative disorders, metabolic dysfunction, and cardiovascular conditions, the peptide remains investigational with no completed human clinical trials for therapeutic applications. Humanin is not approved by the FDA or other regulatory agencies for clinical use.
