A mitochondria-derived peptide encoded in the mitochondrial 12S rRNA, studied for its roles in metabolic regulation, insulin sensitivity, and longevity.
BACKGROUND: MOTS-c is known as mitochondrial open reading frame (ORF) of the twelve S c, produced by a small ORF-encoded peptides (SEPs) in mitochondrial 12S rRNA region. There is growing evidence that MOTS-c has a strong relationship with the expres…
Sodium-glucose cotransporter 2 (SGLT2) inhibitors produce cardioprotective effects on heart failure (HF), even in the absence of diabetes. However, the underlying mechanisms of this cardioprotective effect remain unexplored. The purpose of this study…
Adrenal tumors, such as adrenocortical carcinoma (ACC), adrenocortical adenoma (ACA), and pheochromocytoma (PCC) are complex diseases with unclear causes and treatments. Mitochondria and mitochondrial-derived peptides (MDPs) are crucial for cancer ce…
Radiation-induced lung injury (RILI) is a prevalent complication of thoracic tumor radiotherapy and accidental radiation exposure. Pyrroloquinoline quinone (PQQ), a novel vitamin B, plays a crucial role in delaying aging, antioxidation, anti-inflamma…
An impairment of plasma membrane repair has been implicated in various diseases such as muscular dystrophy and ischemia/reperfusion injury. MOTS-c, a short peptide encoded by mitochondria, has been shown to pass through the plasma membrane into the b…
Skeletal muscle hypertrophy is generally associated with a fast-to-slow phenotypic adaptation in both human and rodent models. Paradoxically, this phenotypic shift is not paralleled by a concomitant increase in mitochondrial content and aerobic marke…
Mitochondrial-nuclear communication plays a vital role in maintaining cellular homeostasis. MOTS-c, a short peptide derived from the 12S rRNA of mitochondrial DNA, has been suggested as a retrograde mitochondrial signal. Although recent clinical stud…
An East Asian-specific 1382A>C polymorphism in the mitochondrial open reading frame of the 12S rRNA type-c results in an amino acid substitution from Lys (K) to Gln (Q) at the 14th amino acid residue. This study investigated the association between m…
The mitochondrial DNA (mtDNA) can trigger immune responses and directly entrap pathogens, but it is not known to encode for active immune factors. The immune system is traditionally thought to be exclusively nuclear-encoded. Here, we report the ident…
MOTS-c is a mitochondrial microprotein that improves metabolism. Here, we demonstrate CK2 is a direct and functional target of MOTS-c. MOTS-c directly binds to CK2 and activates it in cell-free systems. MOTS-c administration to mice prevented skeleta…
Chronic low-grade inflammation is a characteristic of diabetes, which often culminates in cardiovascular events including myocardial damage, thereby increasing the risk of debilitating cardiac complications. The mitochondria-derived peptide MOTS-c re…
BACKGROUND: The objective of this study was to evaluate the levels of Vascular Peroxidase 1 (VPO1), humanin, and MOTS-c in relation to miR-200c expression in untreated preeclamptic pregnancies, and to compare these findings with endoglin levels. METH…
Acute lung injury (ALI) is a life-threatening complication of cardiac surgery that has a high rate of morbidity and mortality. Epithelial ferroptosis is believed to be involved in the pathogenesis of ALI. MOTS-c has been reported to play a role in re…
OBJECTIVES: Mitochondrial open-reading-frame of the twelve S rRNA-c (MOTS-c) is a mitochondrial derived peptide which has beneficial effects on muscle metabolism, insulin sensitivity, weight regulation, and bone mineral density. This study aims to in…
MOTS-c, a recently discovered mitochondrial-derived peptide, plays an important role in many physiological and pathological functionsadenosine monophosphate-activated protein kinase (AMPK) activation. Numerous studies have demonstrated that AMPK is a…
People with sedentary lifestyles engage in minimal or no physical activity. A sedentary lifestyle promotes dysregulation of cellular redox balance, diminishes mitochondrial function, and increases NADPH oxidase activity. These changes collectively in…
Unloading of slow-twitch muscles results in increased muscle fatigue and the mechanisms of this effect are poorly studied. We aimed to analyze the role of high-energy phosphates accumulation during the first week of rat hindlimb suspension plays in a…
MOTS-c, a mitochondrial-derived peptide (MDP), is an essential regulatory mediator of cell protection and energy metabolism and is involved in the development of specific diseases. Recent studies have revealed that MOTS-c promotes osteoblast prolifer…
PURPOSE: The increasing prevalence of obesity in children and its associated risk with cardiovascular diseases demand more discovery of the novel biomarkers for developing new treatment options for this complex disease. This study aimed to investigat…
