The Rise of Mitochondrial-Derived Peptides

Small open reading frames changed the map

Mitochondrial DNA was long viewed mainly through its classical protein-coding genes. Research has identified short open reading frames that can produce bioactive peptides such as humanin, MOTS-c, and SHLPs.

These peptides participate in stress signaling

Experimental studies link mitochondrial-derived peptides to metabolism, inflammation, apoptosis, oxidative stress, and communication between mitochondria and the nucleus.

MOTS-c is a leading example

MOTS-c has been studied in AMPK-related pathways, folate and purine metabolism, exercise biology, and cellular stress responses. Much of the administration literature remains preclinical.

Endogenous association is not intervention evidence

Measurements of circulating peptide levels in disease populations may reveal biomarkers, but they do not establish what happens when a synthetic peptide is administered.

The field still needs basic answers

Assay standardization, tissue sources, processing, receptors, pharmacokinetics, and human safety remain active research areas.
