What the research says

Aggregated from the cited literature below. We summarize sources — we don't author claims.

Humanin is described as a mitochondrial-derived peptide encoded by mitochondrial DNA (mtDNA). Research has investigated humanin as a cytoprotective polypeptide involved in cellular stress responses and apoptosis-related regulation, and it has been discussed in contexts including metabolic regulation, cardiovascular disorders, cancer/degenerative diseases, and reproductive/testicular functions. (PMIDs: 33130077, 32680738, 30582721, 34534645)

Mechanism (as reported)

A review reported that humanin inhibits mitochondrial complex 1 activity and limits oxidative stress in cells. (PMID: 32680738) Additional review(s) characterized humanin as a cytoprotective peptide regulating signaling mechanisms such as JAK/STAT pathways and interactions involving the BCL-2 family, with reported effects across multiple cell types under stress/apoptosis conditions. (PMIDs: 33130077, 30582721)
