Order MOTS-c Mitochondrial Peptide in Denver:
MOTS-c (mitochondrial open reading frame of the 12S rRNA-c) is a 16-amino acid peptide encoded within the mitochondrial genome, discovered in 2015 by researchers at the University of Southern California. Unlike traditional peptides derived from nuclear DNA, MOTS-c represents a novel class of signaling molecules originating directly from the mitochondria, the cell's energy-producing organelles.
What Is MOTS-c and How Does It Work?
MOTS-c functions as a metabolic signaling peptide that influences cellular energy regulation through the AMPK pathway.
The peptide has been shown to:
Activate AMPK signaling: MOTS-c increases phosphorylation of AMPK at Thr172, with studies showing a 2-fold increase in the p-AMPK/AMPK ratio compared to controls. This activation occurs at relatively low doses (10 µM) in cellular models.
Enhance glucose metabolism: The peptide increases glycolysis in HEK293 cells through an AMPK-dependent mechanism. In vivo studies demonstrate that MOTS-c (0.5 mg/kg/day, intraperitoneal) improves glucose clearance in mice fed a normal diet.
Improve mitochondrial bioenergetics: Research indicates MOTS-c treatment enhances intrinsic mitochondrial function through both PGC-1α and AMPK-dependent pathways, without necessarily increasing mitochondrial protein content. This suggests improvements in mitochondrial efficiency rather than simply increased volume.
Reduce oxidative stress: MOTS-c lowers mitochondrial reactive oxygen species (ROS) emission and ROS-related protein damage, indicating substantial alleviation of cellular oxidative stress.
Research Applications of MOTS-c
Metabolic Health and Insulin Resistance
MOTS-c has been studied extensively for its role in metabolic homeostasis. In CD-1 mice, MOTS-c prevents high-fat diet-induced obesity and hyperinsulinemia. It also increases skeletal muscle AMPK activation and GLUT4 expression, which are critical for glucose uptake.
In a type 2 diabetes rat model, MOTS-c (0.5 mg/kg daily for 8 weeks) significantly decreased fasting blood glucose by 35%, reduced HOMA-IR by 40%, and lowered plasma triglycerides and total cholesterol by 25-30% compared to diabetic controls. The peptide also activated myocardial AMPK/Nrf2 antioxidant pathways and reduced mitochondrial damage.
Tissue Repair and Membrane Integrity
Recent research published in Theranostics (2024) revealed that MOTS-c participates in plasma membrane repair by facilitating the translocation of TRIM72 to damaged membranes. The study demonstrated that moderate-intensity exercise increases the interaction between MOTS-c and TRIM72, promoting sarcolemma integrity. Importantly, MOTS-c was shown to preserve heart function and blunt ischemia/reperfusion-induced membrane disruption.
Neuroprotection and Inflammation
In a traumatic brain injury model in mice, MOTS-c (50 mg/kg, intraperitoneal, once daily for 21 days) reduced neurological severity scores by 45% and inhibited the HMGB1/TLR4/NF-kB inflammatory pathway in brain tissue . The peptide also demonstrated anti-nociceptive and anti-inflammatory effects in a formalin-induced paw inflammation model, reducing paw licking time by 60% and suppressing spinal p-ERK/p-JNK/p-P38 and c-fos expression.
Age-Related Macular Degeneration
A 2025 study published in Human Cell explored MOTS-c's therapeutic potential in age-related macular degeneration. The research found that MOTS-c has dose-dependent effects on apoptosis, inflammation, and mitochondrial biogenesis in differentiated retinal pigment epithelial cells. Lower doses (500 nM) demonstrated more significant impacts than higher concentrations (5 µM).
Peptide Purity and Quality Standards
For research applications, peptide purity is critical. Certified analysis of MOTS-c peptides typically shows purity exceeding 95%, with high-quality batches reaching 99.615% purity by HPLC. The molecular weight of MOTS-c (sequence: MRWQEMGYIFYPRKLR) is approximately 2174.60 Da. Mass spectrometry verification confirms the correct molecular identity, with observed masses matching theoretical values (e.g., 2174.55 vs. 2174.60).
