Mitochondrial Peptides
Compounds studied for mitochondrial function, metabolic signaling, and cellular energy regulation in preclinical models
Class Overview
Mitochondrial peptides are a research class centered on compounds that originate from or act upon mitochondrial biology. This class includes MOTS-c, a peptide encoded within the mitochondrial genome, as well as NAD+ and Epithalon, which modulate mitochondrial function through upstream metabolic and epigenetic pathways. Research across this class examines AMPK activation, sirtuin pathway signaling, mitochondrial biogenesis, and the retrograde communication between mitochondria and the nucleus. Published preclinical literature documents these compounds in aging, metabolic, and energy regulation models.
Compounds in This Class
Each compound contributes a distinct mechanism within this research class.
MOTS-c
Role in Class
Mitochondrial-encoded peptide studied for AMPK activation, nuclear translocation under metabolic stress, and metabolic flexibility in rodent models.
NAD+
Role in Class
Coenzyme studied for sirtuin activation, PARP-dependent DNA repair, and mitochondrial biogenesis in aging cell and animal models.
Epithalon
Role in Class
Pineal tetrapeptide studied for telomerase activation and mitochondria-associated longevity signaling in aging preclinical models.
Research Context
The mitochondrial peptide field gained significant momentum following the identification of MOTS-c as a mitochondrial-genome-encoded peptide in 2015 by Lee and colleagues. This discovery established that the mitochondrial genome produces bioactive peptides that function as retrograde signals to the nucleus. Combined with the established NAD+ and sirtuin literature, this class represents one of the most active areas of current longevity and metabolic research. Published studies examine these compounds in the context of aging, exercise physiology, and metabolic disease models.
