Introduction

MOTS-C is a 16-amino-acid mitochondrial-derived peptide encoded within mitochondrial DNA. It has attracted research interest because mitochondrial signaling plays a major role in metabolic regulation, cellular stress adaptation, skeletal muscle and aging biology.

Research Areas

Mitochondrial signalingInsulin sensitivityMetabolic homeostasisSkeletal muscleExercise physiologyAging biology

Mechanisms

Research describes MOTS-C involvement in metabolic regulation and cellular stress-response pathways in experimental systems.

Human Evidence

Researchers have detected endogenous MOTS-C in human blood and skeletal muscle, and human exercise studies show that endogenous MOTS-C levels can respond to physical activity. That does not establish the safety or effectiveness of administering synthetic MOTS-C to humans.

Human research is presented for scientific and educational context only. Elev8 Health does not recommend that its products be used for anything other than laboratory research purposes, and does not recommend human or veterinary use of any kind.

Preclinical Evidence

A foundational Cell Metabolism study reported that MOTS-C influenced metabolic homeostasis and insulin sensitivity in experimental models. Mouse research has investigated MOTS-C in diet-induced obesity, age-associated insulin resistance and physical performance.

Limitations

Human research has largely characterized naturally occurring MOTS-C rather than administered MOTS-C. FDA has stated that it has not identified sufficient human exposure information for administered MOTS-C to characterize safety.

Safety & Regulatory

MOTS-C is not FDA approved. FDA compounding materials note insufficient human exposure information for administered MOTS-C.

Conclusion

MOTS-C is a mechanistically compelling research target with strong preclinical metabolic findings and an underdeveloped administered-human evidence base.

The Mitochondrial-Derived Peptide MOTS-c Promotes Metabolic Homeostasis and Reduces Obesity and Insulin Resistance

Cell Metabolism • 2015

Studied

Investigated MOTS-C in metabolic homeostasis and insulin sensitivity.

Findings

MOTS-C regulated metabolic pathways and insulin sensitivity in experimental models and prevented diet- and age-associated metabolic dysfunction in mice.

Limitations

Animal and cellular research; does not establish effects of administered MOTS-C in humans.

Acute Endurance Exercise Stimulates Circulating Levels of Mitochondrial-Derived Peptides in Humans

Human physiology research • 2021

Studied

Measured naturally occurring mitochondrial-derived peptide responses to acute endurance exercise.

Findings

Endogenous MOTS-C levels responded to physical activity in human participants.

Limitations

Investigated naturally occurring MOTS-C responses, not administration of an Elev8 MOTS-C research vial.

Human research is presented for scientific and educational context only. Elev8 Health does not recommend that its products be used for anything other than laboratory research purposes, and does not recommend human or veterinary use of any kind.
