Mitochondrial-Derived Signaling
MOTS-c is a 16-amino acid peptide encoded by the mitochondrial genome rather than the nuclear genome. It represents a paradigm shift in how researchers view mitochondria—not just as "powerhouses" but as active signaling hubs for systemic regulation.
AMPK Activation
A primary focus of MOTS-c research is its ability to activate the AMP-activated protein kinase (AMPK) pathway. This signaling pathway is a central regulator of energy metabolism, influencing how cells process glucose and fatty acids.
Links to Aging and Exercise
Studies have explored how MOTS-c levels correlate with exercise and the aging process, with research investigating its potential to mitigate metabolic decline in various age-sensitive experimental models.
