As a trusted peptide vendor uk and leading EU peptide supplier, we provide researchers across Europe with MOTS-c for sale that delivers exceptional purity, consistency, and documented quality for advanced metabolic and aging studies.
MOTS-c is a 16-amino acid bioactive peptide encoded by a short open reading frame (sORF) within the mitochondrial 12S rRNA region, representing a groundbreaking discovery in mitochondrial biology . Unlike most proteins encoded by nuclear genes, MOTS-c is produced within mitochondria and acts as a mitochondrial-derived signaling peptide (MDSP), establishing a direct communication link between mitochondrial function and systemic metabolic regulation . This peptide has been shown in extensive preclinical research to regulate metabolic homeostasis, stress responses, and cell survival—potentially influencing how cells age and adapt to metabolic stress .
The molecular formula of MOTS-c is C₈₉H₁₃₃N₂₅O₂₃, with a molecular weight of approximately 1953.2 Da. Its amino acid sequence is Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Ser . MOTS-c translation obligatorily occurs in the cytoplasm using the standard genetic code, requiring export of its polyadenylated transcript from mitochondria—a mechanism that highlights the sophisticated communication between mitochondrial and nuclear genomes .
MOTS-c has captured the attention of the scientific community for its remarkable effects on metabolic health. Treatment and overexpression of MOTS-c increase AMP-activated protein kinase (AMPK) activity, offering protection against insulin resistance . Its primary target organ appears to be skeletal muscle, where its cellular actions inhibit the folate cycle and its tethered de novo purine biosynthesis, leading to AMPK activation . MOTS-c treatment in mice prevents age-dependent and high-fat diet-induced insulin resistance, as well as diet-induced obesity .

The Scientific Foundation of MOTS-c Research
Discovery and Mitochondrial Origin
The identification of MOTS-c emerged from an in silico search for potential short open reading frames (sORFs) within the human 12S rRNA region, revealing one consisting of 51 base pairs with a strong Kozak sequence that translates into a 16 amino acid peptide . Multiple peptide sequence alignment across 14 species demonstrates that MOTS-c is highly conserved, especially the first 11 residues, with four residues undergoing positive selection and two undergoing purifying selection, indicating evolutionary pressure to maintain its function .
The mitochondrial origin of MOTS-c has been rigorously confirmed through multiple experimental approaches. Selective depletion of mitochondrial DNA in HeLa cells (HeLa-ρ0) eliminates both 12S rRNA and MOTS-c transcripts, while mitochondrial RNA depletion using actinonin results in time-dependent loss of MOTS-c expression . MOTS-c is detected in various tissues in mice and rats, as well as in circulation in human and rodent plasma . Notably, fasting lowers endogenous expression of MOTS-c in metabolically active and mitochondria-rich tissues (skeletal muscle and testes) while homeostatic tissues (such as brain and heart) show sustained levels .
Mechanism of Action: AMPK Activation and Metabolic Regulation
MOTS-c works by modulating several key pathways crucial for cellular energy balance and stress resilience :
AMPK Pathway Activation: MOTS-c enhances AMP-activated protein kinase (AMPK) activity, which promotes glucose uptake, fatty acid oxidation, and mitochondrial biogenesis . Its cellular actions inhibit the folate cycle and its tethered de novo purine biosynthesis, leading to endogenous accumulation of 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR)—a well-known AMPK activator . This mechanism positions MOTS-c as a central regulator of cellular energy homeostasis.
Insulin Signaling Modulation: MOTS-c improves insulin sensitivity by increasing glucose uptake in skeletal muscle in response to insulin . This enhanced insulin sensitivity translates into better glucose control and energy utilization, making MOTS-c particularly relevant for metabolic research.
Regulation of Oxidative Stress: MOTS-c helps buffer the intracellular environment against oxidative damage—a contributor to both aging and tissue degeneration . It interacts with pathways involving nuclear factor E2-related factor 2 (Nrf2) to defend antioxidant systems .
Cellular Stress Adaptation: The peptide supports cellular adaptation during metabolic stress, such as fasting or intense exercise, by promoting mitochondrial function and metabolic flexibility .
Effects on Plasma Metabolites
Unbiased metabolomics studies have revealed that MOTS-c significantly alters plasma metabolites associated with insulin resistance . Three key pathways are reduced in MOTS-c-treated mice:
-
Sphingolipid Metabolism: Elevated ceramide and sphingosine 1-phosphate (S1P) levels in plasma contribute to insulin resistance and metabolic syndrome . MOTS-c reduces these sphingolipids, which directly inhibit mitochondrial electron transport and suppress beta-oxidation.
-
Monoacylglycerol Metabolism: MOTS-c modulates the activity of angiopoietin-like proteins (ANGPTLs) that regulate lipoprotein lipase activity, influencing fatty acid uptake by tissues .
-
Dicarboxylate Metabolism: Increases in dicarboxylates generally indicate dysfunction of normal mitochondrial and peroxisomal beta-oxidation. MOTS-c’s reduction of these metabolites suggests improved fatty acid oxidation capacity .
These pathways are typically upregulated in obese and type 2 diabetes models, and their reduction by MOTS-c provides mechanistic insight into how the peptide improves insulin sensitivity, reduces body weight, and decreases fatty liver accumulation .
MOTS-c in Metabolic Disease Research
Insulin Resistance and Type 2 Diabetes: A systematic review and meta-analysis of 602 participants demonstrated that circulating MOTS-c levels are significantly reduced in diabetic individuals (SMD = -0.89; 95% CI -1.12 to -0.65; P < 0.05) . MOTS-c levels are correlated with markers of insulin resistance including fasting insulin level, HOMA-IR, and HbA1c . MOTS-c treatment in mice prevented age-dependent and high-fat diet-induced insulin resistance, as well as diet-induced obesity .
Obesity Research: Interestingly, meta-analysis revealed opposite results for MOTS-c changes in obesity versus diabetes. In obese individuals (BMI > 28 kg/m²), MOTS-c levels were significantly increased (SMD = 0.51; 95% CI 0.21 to 0.81; P < 0.05) . This differential regulation suggests that MOTS-c may serve as a compensatory mechanism in obesity that becomes overwhelmed or dysregulated with progression to diabetes. MOTS-c levels are significantly positively correlated with total cholesterol (r = 0.29, 95% CI 0.20 to 0.38) and LDL-c (r = 0.30, 95% CI 0.22 to 0.39) .
Age-Related Metabolic Decline: Observational studies have shown that circulating MOTS-c levels decline with age, which is associated with increased risk of age-related diseases, such as type 2 diabetes and frailty . MOTS-c treatment in mice prevented age-dependent insulin resistance, highlighting its potential for aging research .
MOTS-c in Cardiovascular Research
MOTS-c has emerged as a promising molecule for cardiovascular research, particularly in diabetic cardiomyopathy. In streptozotocin (STZ)-induced type 1 diabetic mouse models, MOTS-c administration for 3 months significantly improved cardiac function :
-
Improved Systolic Function: Left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were significantly improved by MOTS-c administration .
-
Attenuated Cardiac Remodeling: Elevated cardiac chamber dimensions (left ventricular internal diameter at systole and diastole) were attenuated by MOTS-c .
-
Reduced Pathology: MOTS-c attenuated cardiac hypertrophy, fibrosis, and apoptosis in diabetic mouse hearts .
-
Molecular Effects: Significant activation of AMPK (phosphorylation at Thr172) and reduction in myocardial inflammation (tumor necrosis factor-α, Interleukin-1β) were observed .
MOTS-c also regulates the ROS/TXNIP/NLRP3 pathway and repairs myocardial damage by inhibiting the CCN1/ERK1/2/EGR1 pathway in diabetic rats, demonstrating its multi-faceted cardioprotective effects .
MOTS-c in Muscle and Aging Research
Sarcopenia and Muscle Health: Mitochondrial dysfunction is well-established in sarcopenia—the progressive loss of skeletal muscle mass and function with advancing age . MOTS-c, as a mitochondria-derived peptide, targets several underlying causes of sarcopenia :
-
Impaired glucose uptake in muscle
-
Poor mitochondrial energy production
-
Deficient muscle regeneration
-
Increased oxidative stress
In older adults, higher MOTS-c blood levels correlate with better muscle function, strength, and reduced frailty indices . MOTS-c reduces myostatin and muscle atrophy signaling, and some data suggest a link between MOTS-c and muscle adaptation to physical activity .
Exercise Mimetic Properties: MOTS-c is an exercise-induced mitochondrial-encoded regulator of age-dependent physical decline and muscle homeostasis . It is induced in response to exercise and metabolic stress and travels to the nucleus in a retrograde fashion to control gene expression of many stress-responsive and antioxidant-responsive genes . The exercise benefits of MOTS-c have led to its inclusion in the World Anti-Doping Agency (WADA) list of prohibited substances .
MOTS-c in Bone Health Research
MOTS-c suppresses ovariectomy-induced osteoporosis via AMPK activation and improves osteoporosis through the TGF-β/Smad pathway . It suppresses ovariectomy-induced bone loss and regulates adipose homeostasis to prevent metabolic dysfunction . These findings highlight MOTS-c’s relevance for research into age-related bone loss and metabolic bone diseases.
MOTS-c in Adrenal and Endocrine Research
Recent studies have revealed that MOTS-c functions as a metabolic conductor that primes adrenocortical cells for enhanced steroidogenic responsiveness without stimulating basal hormone synthesis . Key findings include:
-
Novel Gene Targets: RNA-seq identified 39 differentially expressed genes, notably upregulation of purinergic receptor P2ry4 (4.3-fold, P < 0.05)—a novel MOTS-c target enhancing calcium signaling .
-
Pathway Modulation: Gene Set Enrichment Analysis revealed inhibition of cAMP response, mitophagy, and histone deacetylation pathways, alongside activation of cell proliferation, indicating metabolic reprogramming without steroidogenic activation .
-
Stress Marker Regulation: Downregulation of stress markers Bag3 and Smurf2, mitochondrial carrier Slc25a30, and peroxisomal factor Pex11a .
These findings reveal a novel preparatory mechanism in adrenal physiology and identify MOTS-c as a potential therapeutic target for HPA axis disorders requiring enhanced adrenal reserve capacity without basal hypercortisolemia .
