Description
MOTS-c (Met-Arg-Trp-Glu-Met-Ile-Gln-Lys-Val-Gly-Gln-Tyr-Gln-Leu-Glu-Gln) is a 16-amino acid peptide encoded by the mitochondrial genome. Unlike nuclear-encoded peptides, MOTS-c directly influences cellular energy regulation and stress adaptation, playing a critical role in metabolic health and longevity research.
Mechanism of Action
-
Activates AMP-activated protein kinase (AMPK) and PGC-1α pathways
-
Promotes fatty acid oxidation and improves glucose utilization
-
Enhances mitochondrial biogenesis and cellular energy efficiency
-
Supports resistance to metabolic and oxidative stress, making it valuable for longevity studies
Dosage Guidelines (Research Use)
-
General Dose: 5–10 mg per injection
-
Frequency: 2–3 times per week
-
Cycle Length: Commonly 4 weeks, followed by a break period
-
Important Note: Emerging data suggest MOTS-c may have limited stability (~10 minutes) post-reconstitution, warranting careful handling during experiments
