What this study reported

Reviewed the eight identified mitochondrial-derived peptides, noting that MOTS-c is encoded within the 12S rRNA gene (MT-RNR1) while humanin and the small humanin-like peptides are encoded by the 16S rRNA gene. Summarised reported anti-apoptotic, anti-inflammatory and cardioprotective activities, proposed roles as metabolic sensors linked to mtDNA mutation-associated and age-associated disorders, and discussed reported associations with Alzheimer's disease, cognitive decline, macular degeneration and cataracts.

Limitations

Narrative review chapter with no stated search strategy or quality appraisal; MOTS-c is covered as one of eight peptides rather than as the main subject; discussion of interventions is forward-looking rather than evidence-graded.

Appraisal

Each dimension is recorded separately and never combined into a single score. A study can be well controlled and still tell you little about people.
