MOTS-c in sepsis-induced cardiomyopathy: Mechanisms and translational potential.
Editor's note
An unusually disciplined review: the authors explicitly separate findings generated in sepsis-induced cardiomyopathy models from those extrapolated from other cardiovascular and metabolic settings, which is precisely the distinction most MOTS-c writing blurs. Their conclusion is that MOTS-c is plausible but insufficiently validated here, and they flag biomarker specificity and biodistribution under septic conditions as open problems. No human data, no dosing, no efficacy claim. Worth logging for readers following MOTS-c as a mitochondrial-stress signal rather than as anything clinically actionable.
Plain-language abstract
This review asks whether MOTS-c, a small protein encoded inside mitochondrial DNA, has any role in the heart dysfunction that accompanies sepsis. MOTS-c is known to act on AMPK-linked energy metabolism, antioxidant responses and blood-vessel lining function, all of which are disturbed in septic hearts. The authors are direct that almost none of the evidence comes from sepsis models specifically, and that pharmacokinetics in sepsis are unknown.
