A mitochondria-derived peptide encoded in the mitochondrial 12S rRNA, studied for its roles in metabolic regulation, insulin sensitivity, and longevity.
INTRODUCTION: Vascular calcification (VC) is a complex, regulated process involved in many disease entities. So far, there are no treatments to reverse it. Exploring novel strategies to prevent VC is important and necessary for VC-related disease int…
Cellular stress response is coordinated through the communication between mitochondria and the nucleus. However, whereas mitochondria are regulated by nuclear-encoded proteins, the nucleus was considered ungoverned by mitochondrial-encoded factors. W…
Cold exposure stress causes hypothermia, cognitive impairment, liver injury, and cardiovascular diseases, thereby increasing morbidity and mortality. Paradoxically, cold acclimation is believed to confer metabolic improvement to allow individuals to…
BACKGROUND: Q fever fatigue syndrome (QFS) is a well-documented state of prolonged fatigue following around 20% of acute Q fever infections. It has been hypothesized that low grade inflammation plays a role in its aetiology. In this study, we aimed t…
OBJECTIVE: To investigate whether MOTS-c can regulate the synthesis of type I collagen in osteoblasts by regulating TGF-β/SMAD pathway, thereby improving osteoporosis. MATERIALS AND METHODS: Viability of hFOB1.19 cells treated with MOTS-c was detecte…
OBJECTIVE: Polycystic ovarian syndrome (PCOS) is a heterogeneous endocrine disorder associated with mitochondrial dysfunction and insulin resistance (IR). MOTS-c, a mitochondrial peptide, promotes insulin sensitivity (IS) through activating AKT and A…
MOTS-c, as a mitochondria derived peptide, exerts benefits for insulin resistance in HFD mice and against various stresses in an AMPK dependent way. Here, in the D-galactose chronic injection models, exogenous MOTS-c was given to determine its direct…
The postmenopausal state is associated with an increased risk of metabolic disorder including reduced energy expenditure and weight gain, leading to higher cardiovascular and cancer risks among other diseases. Mitochondrial-derived peptide (MOTS-c) i…
Mitochondria are ancient organelles that emerged from the endosymbiosis of free-living proto-bacteria. They still retain a semi-autonomous genetic system with a small genome. Mitochondrial DNA (mtDNA) codes for 13 essential proteins for the productio…
RATIONALE: The mitochondrial open reading frame of 12S rRNA type-c (MOTS-c) peptide was recently discovered and described to control metabolic homeostasis through AMPK activation along with AICAR accumulation. Consequently, it appears advisable to mo…
Besides their well-known function in cellular bioenergetics, the role of mitochondria in signaling regulation of cells homeostasis and survival has been uncovered during the past few decades. Possessing an independent genome and a unique genetic code…
Mitochondria-derived peptides (MDPs) are a series of peptides encoded by mitochondrial DNA, and have similar functions to mitochondria. At present there are three types of MDPs that have been found, including Humanin, MOTS-c and SHLP1-6. They are new…
Mitochondrial dysfunction is implicated in the pathogenesis of Type 2 diabetes (T2D) and the development of diabetes related complications such as cardiovascular disease and stroke. Mitochondria produce several small polypeptides that may influence m…
MOTS-c is an exercise mimetic and improves insulin sensitivity in aged and diet-induced obese mice. Although plasma markers are good markers for the metabolic condition, whether MOTS-c changes plasma markers in diet-induced obese mice has not been ex…
The Mitochondrial-derived peptide MOTS-c has recently been reported as a 16-amino acid peptide regulating metabolism and homeostasis in different cells. However, its effects on immune cells and bone metabolism are rarely reported. Here we demonstrate…
Mitochondria are increasingly being recognized as information hubs that sense cellular changes and transmit messages to other cellular components, such as the nucleus, the endoplasmic reticulum (ER), the Golgi apparatus, and lysosomes. Nonetheless, t…
Advanced chronic kidney disease (CKD) is characterized by a premature aging phenotype of multifactorial origin. Mitochondrial dysfunction is prevalent in CKD and has been proposed as a major contributor to poor muscle function. Although the mitochond…
OBJECTIVE: To elucidate the function of MOTS-c in accelerating bone fracture healing by inducing BMSCs differentiation into osteoblasts, as well as its potential mechanism. MATERIALS AND METHODS: Primary BMSCs were extracted from rats and induced for…
Mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) is a mitochondrial-derived peptide that attenuates weight gain and hyperinsulinemia when administered to high fat-fed mice. MOTS-c is therefore a potential regulator of metabolic homeostasis…
