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…
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…
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…
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…
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…
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…
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…
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…
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…
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…
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have transformed metabolic and aesthetic medicine, yet their potential influence on botulinum toxin type A (BoNT-A) pharmacodynamics remains unexplored. Using the AesthetiSIM™ microsimulation plat…
A sensitive and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the quantification of tirzepatide, a dual agonist of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1…
Tirzepatide is the first dual long-acting glucose-dependent insulinotropic polypeptide receptor and glucagon-like peptide-1 receptor agonist indicated for the treatment of type 2 diabetes in adults, for reducing excess body weight and maintaining lon…
The anorectic peptide-based obesity management medications (OMM) have dominated the treatment of obesity over the last decade. This review analyses the evidence that has laid the ground for the three most frequently used drugs (liraglutide, semagluti…
AIMS: In SURMOUNT-5, tirzepatide led to greater body weight (BW) reduction versus semaglutide in adults with obesity without T2D. Health-related quality of life (HRQoL) with tirzepatide versus semaglutide in SURMOUNT-5 was evaluated. MATERIALS AND ME…
OBJECTIVE: This post hoc analysis of SURMOUNT trials assessed the association of baseline physical function (PF) with obesity-related complications (ORCs), efficacy measures, and PF. The mechanism of tirzepatide-led improvements in PF was evaluated.…
BACKGROUND: The comparative gastrointestinal safety across glucagon-like peptide-1 receptor agonists and tirzepatide is still unclear. OBJECTIVE: To compare the risk for severe gastrointestinal adverse events across dulaglutide, subcutaneous semaglut…
OBJECTIVE: To investigate the impact of estrogen deficiency on metabolic dysfunction-associated steatotic liver disease progression and evaluate the therapeutic potential of tirzepatide (Tzp), a dual glucose-dependent insulinotropic polypeptide/gluca…
