Because the functional apoptosis-initiating protein, cytochrome C (CytC) is rapidly cleared from the circulation (t1/2 (half-life): 4 minutes), it cannot be used for in vivo therapy. We report herein on a hitherto unreported strategy for delivering exogenous CytC as a potential and safe antiobesity
BACKGROUND
Obesity represents a heterogeneous group of disorders associated with broad spectrum of metabolic and endocrine abnormalities. The metabolic changes in obesity may also concern the efficacy of mitochondrial system of energy provision. The aim of our study was to analyse activities of
Non-alcoholic fatty liver disease, characterized by hepatocyte apoptosis, is distinct in fatty liver and non-alcoholic steatohepatitis, the more severe form. Apoptotic cell death is caspase-dependent and associated with mitochondrial membrane depolarization and cytochrome c release. Adhering to the
Peptides that target tissue for an apoptotic death have potential as therapeutics in a variety of disease conditions. The class of peptides described herein enters the cell through a specific receptor-mediated interaction. Once inside the cell, the peptide migrates toward the mitochondria, where the
Obesity is an independent risk factor for chronic kidney disease. Recently, urinary mitochondrial DNA (mtDNA) has been used as a surrogate marker of mitochondrial damage in various kidney diseases. However, there are no data regarding its use in patients with obesity or the change in Reduced skeletal muscle mitochondrial content and fatty acid oxidation are associated with obesity and insulin resistance. Although the exact mechanisms remain elusive, this may result from impaired mitochondrial biogenesis or reductions in the mitochondrial reticulum network. Therefore, the purpose
OBJECTIVE
To determine whether reducing free fatty acids (FFAs) concentration has a protective effect on cardiac structure and function in high-fat-diet-induced obese rat.
METHODS
Sprague-Dawley rats were randomly divided into normal control, obesity and fenofibrate group. After 8 or 16 weeks, the
Dietary supplementation with melinjo (Gnetum gnemon L.) seed extract (MSE) has been proposed as an anti-obesity strategy. However, it remains unclear how MSE modulates energy balance. We tested the hypothesis that dietary MSE reduces energy intake and/or increases physical activity and metabolic
BACKGROUND
Obesity-related fatty liver disease is linked to mitochondrial dysfunction and oxidative stress. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) regulates mitochondrial function and is a transcriptor of multiple genes that produce antioxidants. Because Roux-en-Y gastric bypass (RYGB)
BACKGROUND
We investigated a subject with an isolated cytochrome c oxidase (COX) deficiency presenting with an unusual phenotype characterised by neuropathy, exercise intolerance, obesity, and short stature.
RESULTS
Blue-native polyacrylamide gel electrophoresis (BN-PAGE) analysis showed an almost
A high-fat diet induces obesity in mice, leading to insulin resistance, decreased mitochondrial function, and increased apoptosis in the hippocampus, which eventually result in memory loss. The present study investigated the effect of physical exercise on memory, hippocampal mitochondrial function,
This study tested the hypothesis that exendin-4 protects against critical limb ischemia (CLI) in obese mice undergoing hypoxic stress (H). B6 mice were categorized into aged-matched control (C)-H (group 1-A), obesity (induced by high-fat diet) (O)-H (group 1-B), C-H-CLI (group 2-A), O-H-CLI (group
BACKGROUND
nocturnal sustained hypoxia during sleeping time has been reported in severe obesity, but no information regarding the cardiac molecular mechanism in the coexistence of nocturnal sustained hypoxia and obesity is available. This study evaluates whether the coexistence of nocturnal
OBJECTIVE
We tested the hypothesis that obesity reduced circulating number of endothelial progenitor cells (EPCs), angiogenic ability, and blood flow in ischemic tissue that could be reversed after obesity control.
METHODS
8-week-old C57BL/6J mice (n=27) were equally divided into group 1 (fed with
Mitochondrial apoptosis and apoptotic signaling modulations by aerobic training were studied in cardiac and skeletal muscles of obese Zucker rats (OZR), a rodent model of metabolic syndrome. Comparisons were made between left ventricle, soleus, and gastrocnemius muscles from OZR (n = 16) and
