MOTS-C

MOTS-c and Fat Metabolism Estrogen research in mice models suggests that the availability of the hormone at low levels may increase fat mass and dysfunction of normal adipose tissues. The introduction of MOTS-c in these mice models appeared to increase the prevalence of brown fat and reduce the accumulation of adipose tissue. The peptide, to an extent, may block the adipose dysfunction and inflammation that follows insulin resistance.

Researchers suggest that a fraction of MOTS-c’s potential action on fat metabolism is mediated via AMP-activated protein kinase (AMPK) pathway activation. The AMPK pathway is activated when cellular energy levels are low, which spurs glucose and fatty acid uptake by cells for metabolism. MOTS-c may act directly on the methionine folate cycle, increasingAICARlevels and AMPK activation. Scientific records in mice studies indicate that in laboratory models of obesity, the peptide is a potentially vital regulator of monoacylglycerol, dicarboxylate, and sphingolipid metabolism. By reducing the activity of these pathways and enhancing beta-oxidation, the peptide may halt fat accumulation. Most of these actions appear to be due to the action of the peptide in the nucleus.[2]The dysregulation of fat metabolism in mitochondria may possibly cause a lack of fat oxidation, resulting in increased levels of fat circulation as insulin levels increase to flush out lipids from the bloodstream. In addition, there is enhanced deposition of fat and a change in homeostasis through increased insulin levels.[3]The scientists also note that“The implications of plasma MOTS-c for metabolic homeostasis deserve future examination.”

MOTS-c and Cardiovascular FunctionA higher risk of endothelial cell dysfunction was reported in research models of coronary angiography. Endothelial cells line the inner wall of blood vessels and are considered vital in regulating blood clotting, blood pressure, and plaque function. Scientific studies report that the peptide does not appear to alter the responsiveness of blood vessels directly; rather it may possibly sharpen endothelial cells to the signaling actions of other molecules like acetylcholine.[8]Introducing the peptide in mice appeared to improve endothelial, microvascular, and epicardial blood vessel functions. Research records indicate that MDPs alongside the MOTS-c, may function to stave off inflammation and stress in cardiomyocytes. It is assumed that a down-regulation of MDP may cause a risk of the development of cardiovascular diseases. MOTS-c may be vital in reperfusion injury and endothelial functions. The mechanisms by which MOTS-c might exert these actions may involve the activation of AMPK which might theoretically enhance endothelial nitric oxide synthase (eNOS) activity. This activity is considered to be crucial for endothelial-dependent vasodilation. Additionally, MOTS-c might modulate inflammatory pathways, potentially reducing endothelial inflammation, which is a hallmark of endothelial dysfunction.
