Study record
MOTS-c promotes muscle differentiation in vitro
García-Benlloch S, Revert-Ros F, Blesa JR et al. · Peptides · 2022
What this study reported
Reported that wild-type MOTS-c increased myotube formation in human LHCN-M2 and murine C2C12 muscle progenitor cells, while a Y8F mutant peptide did not. Reported that wild-type MOTS-c, but not the mutant, limited the interleukin-6-induced reduction in nuclear myogenin staining and blocked interleukin-6-induced STAT3 transcriptional activity, and identified a putative SH2-binding motif in the YIFY region in silico.
Limitations
Two immortalised myoblast lines only, with no primary cells or in vivo confirmation; the SH2-binding motif is predicted in silico and binding is not demonstrated structurally; differentiation endpoints are morphological and reporter-based.

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.
