- Different research models test different aspects of MOTS-c's insulin-sensitizing capacity. The table below compares the three most common experimental designs used in published studies.
- Diet-Induced Obesity (DIO)
- 60% high-fat diet for 8–16 weeks
- 10–15 mg/kg daily
- 50–65% improvement in ITT glucose clearance
- AMPK activation overrides lipid-induced insulin resistance in muscle
- Modeling obesity-related metabolic syndrome
- Aged Mouse Model
- Natural aging (18–24 months old)
- 15–20 mg/kg daily
- 40–55% restoration of glucose tolerance vs young controls
- Restores age-related decline in mitochondrial MOTS-c expression
- Studying age-related metabolic decline and sarcopenia
- Genetic Obesity (ob/ob)
- Leptin deficiency mutation
- 20–30 mg/kg daily
- 35–45% improvement despite ongoing hyperphagia
- Insulin sensitization occurs independent of leptin signaling
- Testing MOTS-c in severe metabolic dysfunction where other interventions fail
- The DIO model is the most widely used because it mimics human metabolic syndrome progression. Gradual onset, diet-driven, reversible with intervention. The aged mouse model is gaining traction because it addresses a clinical reality: insulin resistance worsens with age even in the absence of obesity, and MOTS-c is one of the few interventions shown to reverse this. The ob/ob model is the stress test. If MOTS-c works here, where leptin signaling is completely absent and hyperphagia is uncontrolled, the mechanism must be robust and independent of traditional appetite-regulating pathways.
