Provenance
- Bibliographic fields retrieved from PubMed E-utilities efetch (title, journal, date, authors, DOI) on 2026-11-11.
- Annotated from the published abstract.
- Editorial review: approved (2026-11-11).
- Classification follows the site methodology; the record describes the study, not what MOTS-c does in people.
