MOTS-c RESEARCH
Exercise-Induced Benefits: Exercise causes MOTS-c levels to go up in humans, and MOTS-c treatment improves physical performance in mice of all ages and regulates skeletal muscle metabolism and gene expression.
Metabolic Homeostasis: MOTS-c treatment in mice prevented age-dependent and high-fat-diet-induced insulin resistance, as well as diet-induced obesity, suggesting mitochondria may actively regulate metabolic homeostasis.
Glucose Metabolism Enhancement: MOTS-c has been shown to improve glucose metabolism in skeletal muscle, indicating benefits for diseases such as diabetes, obesity, and aging.
AMPK Pathway Activation: MOTS-c mainly acts through the Folate-AICAR-AMPK pathway, thereby influencing energy metabolism, insulin resistance, inflammatory response, exercise, aging and aging-related pathologies.
Insulin Sensitivity: MOTS-c has been shown to increase glucose uptake in muscle in response to insulin and may modulate metabolites or signaling pathways to improve insulin sensitivity.
Bone Health Benefits: Recent studies revealed that MOTS-c promotes osteoblast proliferation, differentiation, and mineralization while inhibiting osteoclast production and mediating bone metabolism regulation.
Anti-Aging Properties: The MOTS-c protein has both inhibitory effects (inflammation, age-related disorder, apoptosis) and promotes healthy functioning in brain and other tissues.
Mitochondrial Function: MOTS-c has shown promise as a therapeutic for restoring energy homeostasis and muscle function in metabolic diseases.
Mechanism of Action: MOTS-c works through multiple pathways:
AMPK Pathway Activation: Enhances cellular energy sensing
Promotes fat oxidation and glucose uptake
Improves metabolic flexibility
Supports mitochondrial biogenesis
Mitochondrial Function Enhancement: Improves respiratory chain efficiency
Increases ATP production capacity
Enhances oxidative metabolism
Supports cellular energy homeostasis
Nuclear Translocation: MOTS-c translocates to nucleus during stress
Regulates gene expression related to metabolism
Activates stress-response pathways
Promotes cellular adaptation
Exercise-Mimetic Effects:
Mimics beneficial effects of physical exercise
Enhances muscle function and performance
Improves cardiovascular efficiency
Supports training adaptations
