Mitochondrial-Derived Peptide MOTS-c Attenuates Vascular Calcification and Secondary Myocardial Remodeling via Adenosine Monophosphate-Activated Protein Kinase Signaling Pathway

Wei M, Gan L, Liu Z et al. · Cardiorenal Med · 2020

AnimalMOTS-c administeredEvidence tier C

What this study reported

In rats with vitamin D3 plus nicotine-induced vascular calcification, MOTS-c treatment was associated with reduced calcification. Phosphorylated AMPK increased and AT-1 and ET-B receptor expression decreased after MOTS-c treatment.

Limitations

Males only in a single chemically induced model; group sizes not reported; AMPK involvement is correlative, with no inhibitor experiment described.

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.
