MOTS-c (12S rRNA-c mitochondrial open reading frame) is a unique endogenous functional polypeptide composed of 16 amino acids, independently encoded by the mammalian mitochondrial genome. Unlike most traditional mitochondrial functional proteins synthesized by nuclear genes, MOTS-c can be transcribed and translated within the mitochondria. As an important intercellular signaling mediator, MOTS-c connects mitochondrial energy metabolism and systemic physiological regulation. MOTS-c is widely distributed in metabolically active tissues, including skeletal muscle, liver, adipose tissue, and vascular tissue, and its endogenous expression level is closely related to the body's metabolic state. Exercise, energy stress, and external environmental stimuli can all significantly upregulate MOTS-c expression, making it a core topic in mitochondrial biology, metabolic homeostasis, and physiological regulatory mechanisms research. MOTS-c exerts its regulatory function by modulating intracellular metabolic signaling cascades. It can effectively regulate intracellular folate and methionine metabolism, increase endogenous AICAR levels, and further activate the AMPK energy-sensing pathway—a core regulatory pathway for cellular energy metabolism. The activated AMPK signaling pathway comprehensively regulates intracellular energy allocation, promotes mitochondrial biosynthesis and renewal, optimizes nutrient absorption and transport, and maintains stable intracellular redox balance. Under metabolic stress, MOTS-c translocates from mitochondria to the nucleus, selectively binding to target gene promoters and regulating the transcription of various metabolism-related genes. This unique regulatory mode helps cells rapidly adapt to energy fluctuations and stabilize intracellular metabolic homeostasis.

In energy metabolism studies, MOTS-c exhibits a stable and reliable regulatory effect on glucose and lipid metabolism balance. It upregulates the expression of glucose transporters in peripheral metabolic tissues, improving cellular glucose uptake and utilization efficiency, thereby preventing abnormal glucose accumulation. In animal models of metabolic disorders induced by a high-fat diet, exogenous MOTS-c supplementation optimizes nutrient distribution in the body, accelerates the catabolism and turnover of free fatty acids, reduces ectopic lipid deposition in cells and tissues, and alleviates metabolic disorders caused by long-term high-nutrient stimulation. Furthermore, it enhances cellular metabolic flexibility, allowing for free switching between glycolysis and oxidative metabolism, effectively improving metabolic rigidity.

MOTS-c is a key research molecule in skeletal muscle physiology. Prolonged lack of exercise and continuous metabolic stress lead to decreased muscle fiber activity, insufficient energy supply, and abnormal lipid infiltration in muscle tissue. Preclinical studies have confirmed that continuous MOTS-c supplementation can optimize the metabolic state of inactive muscle fibers, stabilize muscle tissue structure, and maintain basic physiological functions. As a classic exercise mimic peptide, MOTS-c can alleviate intracellular oxidative stress and metabolic fatigue caused by high-intensity physiological stimulation, regulate protective signaling pathways in muscle cells, and reduce stress-induced metabolic damage to skeletal muscle tissue.

This peptide plays a crucial role in maintaining mitochondrial functional stability. Prolonged oxidative stress and physiological aging lead to mitochondrial structural damage, reduced respiratory chain activity, and insufficient ATP synthesis, ultimately resulting in decreased cellular physiological function. Research data confirms that MOTS-c can promote the generation of new mitochondria, optimize the efficiency of the mitochondrial respiratory chain, clear excess intracellular oxidative metabolites, balance the redox microenvironment, and reduce oxidative damage to cell membranes and organelles. It can stably maintain mitochondrial functional stability.
