Compound overview
A mitochondrial signal studied in metabolic adaptation.
MOTS-c is a naturally occurring signaling peptide encoded by mitochondrial DNA. Researchers study its role in communication among mitochondria, the nucleus, and metabolic tissues such as skeletal muscle.
Scientific interest centers on how MOTS-c may participate in responses to metabolic stress, exercise, and age-related changes in energy regulation. Its complete role in humans remains under study.
Mechanism under study
Metabolic stress and mitonuclear signaling
During metabolic stress, MOTS-c can move into the nucleus and influence the expression of genes involved in cellular adaptation. Preclinical research links it with energy sensing, metabolic pathways, antioxidant responses, and communication between mitochondrial and nuclear genomes.
Nuclear signaling
During metabolic stress, MOTS-c can accumulate in the nucleus and influence stress-adaptation gene expression.
Mitonuclear communication
Its signaling is being studied as one route through which mitochondrial DNA can influence nuclear programs and whole-cell metabolism.
The complete mechanism—and the significance of these pathways in humans—remains under investigation.
Current research areas
Questions under investigation
- Metabolic homeostasis and insulin sensitivity
- Mitochondrial-to-nuclear communication
- Skeletal-muscle metabolism and exercise response
- Age-related changes in physical capacity
- Cellular stress adaptation and resilience
Evidence summary
Reported research findings
- Metabolic regulation: Animal studies report improvements in glucose regulation and insulin sensitivity.
- Protection against metabolic dysfunction: Mouse studies report protection against diet-induced obesity and age- or diet-related insulin resistance.
- Exercise capacity: Preclinical studies report improved physical performance in young, middle-aged, and older mice.
- Muscle homeostasis: Research examines skeletal-muscle metabolism and adaptation to cellular stress.
- Healthy-aging research: MOTS-c is being studied as a possible regulator of age-related metabolic and physical decline; evidence remains primarily preclinical.
Exercise-related increases in endogenous MOTS-c support its biological relevance and encourage continued study of mitochondrial signaling and externally administered forms.
