A mitochondria-derived peptide encoded in the mitochondrial 12S rRNA, studied for its roles in metabolic regulation, insulin sensitivity, and longevity.
UNLABELLED: Polycystic ovary syndrome (PCOS) is characterized by insulin resistance and metabolic dysfunction. Mitochondrial-derived peptides (MDPs), including MOTS-c, regulate glucose homeostasis and skeletal muscle metabolism. Whether MOTS-c expres…
INTRODUCTION: Mitochondrial open reading frame of the 12S rRNA type-c (MOTS-c), a 16-amino acid mitochondrial-derived peptide, regulates cellular metabolism through AMPK and mTOR signaling and exerts protective effects across multiple endocrine tissu…
INTRODUCTION: MOTS-c (mitochondrial open reading frame of the 12S rRNA type-c) is a mitochondrial-derived peptide and regulator of metabolic homeostasis. Although its role in glucose and lipid metabolism is emerging, changes in circulating MOTS-c wit…
Prolonged exposure to high altitude (HA) results in a range of systemic changes, some of which, specifically for the heart, particularly cardiac changes, remain difficult to reverse after returning to low altitude. Cardiac de-acclimatization after HA…
Glucocorticoids, such as dexamethasone (DEXA), are effective therapeutics but cause severe muscle wasting. Mitochondrial-derived peptides (MDPs) are promising countermeasures, but their effectiveness is largely unexplored. We tested the hypothesis th…
BACKGROUND: This study investigated the effects of dietary graviola (Annona muricata L.) oil extract (GOE) (supplemented at 200, 400, and 600 mg/kg) on the growth performance and circadian rhythm profiles of adipokine, cardiac, and mitochondrial func…
Sarcopenia, a progressive skeletal muscle disorder marked by loss of mass and function, presents growing societal challenges due to limited therapeutic options. Here, we identify mitochondrial dysfunction and oxidative stress as central drivers of sa…
Mitochondria-derived peptides (MDPs) are bioactive molecules encoded by small open reading frames within mitochondrial DNA (mtDNA). Humanin, the first MDP to be discovered, functions as a cytoprotective factor, protecting cells from stress-induced ap…
Hepatocellular carcinoma (HCC), the most common primary liver cancer, is characterized by late diagnosis, limited treatment efficacy, and a highly immunosuppressive tumour microenvironment. Chronic liver injury, fibrosis, and inflammation are central…
The mitochondrial-derived peptide MOTS-c regulates metabolic and cellular stress responses, but its dose-response profile and direct cardioprotective mechanisms in myocardial ischemia-reperfusion injury (MIRI) remain undefined. This proof-of-concept…
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction and repetitive behaviors, with currently limited therapeutic options. Oxidative stress is suggested as significant in ASD pathophysiology, ma…
Myocardial fibrosis stands as a defining pathological characteristic in type 2 diabetes. Aerobic exercise curbs the overproduction of type I/III collagen and boosts matrix metalloproteinases, thereby improving outcomes related to fibrosis in the hear…
OBJECTIVE: Acetaminophen (APAP)-induced liver injury (AILI) is a leading cause of acute liver failure worldwide, but effective therapeutic strategies are still lacking. MOTS-c, a mitochondrial-derived peptide, has demonstrated hepatoprotective proper…
Oxidative stress play key roles in the pathogenesis of bronchopulmonary dysplasia (BPD). MOTS-c is a mitochondria-derived peptide containing 16 amino acids that is reported to be involved in the treatment of oxidative stress-related diseases. However…
Vascular aging profoundly affects the onset of cardiovascular diseases in the elderly, mostly as a result of mitochondrial dysfunction. This review examines the protective roles of mitochondrial- derived peptides such as humanin, MOTS-c, and small hu…
BACKGROUND: Sepsis-associated encephalopathy (SAE) is a serious complication of sepsis, increasing short-term and long-term mortality. It involves neuroinflammation, neuronal damage, and blood-brain barrier (BBB) disruption. MOTS-c, a mitochondrion-d…
Mitochondrial-derived microproteins (MDPs) translate mitochondrial stress into cellular decisions that shape aging, metabolism, cancer biology, and neurodegeneration. Humanin, MOTS-c, SHLPs, and the recently identified SHMOOSE act through distinct in…
Mitochondrial-derived peptides are a small class of regulatory peptides encoded by short open reading frames in mitochondrial DNA. One such peptide, mitochondrial open reading frame of the 12S rRNA-c (MOTS-c), has been shown to exert numerous benefic…
As bioactive microproteins, mitochondrial-derived microproteins (MDPs) are encoded within the small open reading frames of mitochondrial DNA. MDPs have been shown to be altered in a number of disease states and have mitochondrial, nuclear, and extrac…
Mitochondrial function is critical for spermatogenesis and male fertility. MOTS-c, a mitochondrially encoded regulatory peptide, has recently been reported to effectively protect testicular spermatogenesis in mice, but its specific role and mechanism…
