Study record
MOTS-c primes adrenal cortex metabolism without directly driving steroidogenesis
Blatkiewicz M, Kaminski K, Sobalska-Kwapis M et al. · Folia Histochem Cytobiol · 2026
What this study reported
Reported that administered MOTS-c did not alter classical steroidogenic genes or circulating corticosterone and aldosterone in male rats, while RNA sequencing identified 39 differentially expressed adrenal genes, including higher P2ry4 and Apoc4 and lower Bag3, Smurf2, Slc25a30 and Pex11a. Gene set enrichment indicated lower cAMP response, mitophagy and histone deacetylation signals with higher proliferation signals in rat adrenal tissue.
Limitations
Small single-sex rat sample with a short observation window; transcriptomic findings are descriptive and not functionally validated; no stimulated (ACTH or stress) condition tested.

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.
