Mitochondrial-derived peptides in aging and age-related diseases
Kim SJ, Miller B, Kumagai H et al. · Geroscience · 2021
ReviewSeveralEvidence tier R
What this study reported
Reviewed evidence that levels of mitochondrial-derived peptides, including MOTS-c, decline with age and relate to senescence, chronic inflammation and cognitive decline. Also summarised coding-region variants in MOTS-c and humanin reported to associate with age-related disease.
Limitations
Narrative review without systematic search; much of the cited MOTS-c evidence is preclinical or based on cross-sectional associations.
