What is the Meaning of Mitochondrial-Derived Peptides?

Mitochondrial-Derived Peptides (MDPs) are a recently discovered class of short, biologically active peptides translated from small open reading frames within the mitochondrial genome. These molecules, such as Humanin and MOTS-c, function as novel signaling molecules that regulate cellular metabolism, apoptosis, and stress response pathways. MDPs represent a direct link between mitochondrial function, a key driver of cellular aging, and systemic hormonal and metabolic health. Their discovery has opened new avenues for therapeutic interventions targeting cellular vitality and longevity.

What is the Origin of Mitochondrial-Derived Peptides?

The discovery of MDPs is a relatively recent advancement in molecular biology, challenging the long-held view that the mitochondrial genome primarily encodes components for the electron transport chain. The first MDP, Humanin, was identified in the early 2000s, followed by others, including MOTS-c, which highlighted the signaling role of the mitochondria. This area of research integrates genetics, endocrinology, and aging biology.

What is the Mechanism of Mitochondrial-Derived Peptides?

MDPs function primarily as inter-organelle and intercellular signaling molecules that promote metabolic flexibility and cytoprotection. MOTS-c, for example, acts in the cytoplasm to promote glucose uptake and improve insulin sensitivity, mimicking the effects of exercise. Humanin protects cells from apoptosis and oxidative stress, acting as a survival factor. These peptides modulate key metabolic and stress pathways, essentially communicating the energetic status of the cell to the rest of the body.
