Redox regulation of insulin sensitivity due to enhanced fatty acid utilization in the mitochondria.

Obesity enhances the risk for the development of type 2 diabetes and cardiovascular disease. Loss in insulin sensitivity and diminished ability of muscle to take up and use glucose are characteristics of type 2 diabetes. Paradoxically, regulatory mechanisms that promote utilization of fatty acids appear to initiate diet-induced insulin insensitivity. In this review, we discuss recent findings i...

Protective effect of metformin on toxicity of butyric acid and arsenic in isolated liver mitochondria and langerhans islets in male mice: an in vitro study

Objective(s): Arsenic, a toxic metal in drinking water and butyric acid (BA) is a free fatty acid found in many foods. These two can induce oxidative stress in some tissues. The present study investigated the protective effect of metformin against toxicity induced by Arsenic (As) and BA in isolated mice liver mitochondria and pancreatic islets. Materials and Methods: In this study, liver mitoch...

The Effects of Simvastatin on Free Fatty Acids Profile in Fructose-fed Insulin Resistant Rats

Backgrounds: Type 2 diabetes mellitus is the most common metabolic disease and free fatty acids, as signaling molecules, can play a crucial role in the development of it. Different free fatty acids, through various cell membrane receptors, induce different effects on metabolic pathways and thereby affect insulin sensitivity. Simvastatin is a cholesterol decreasing drug prescrib...

Enhanced cardiac fatty acid utilization induced by high dietary fat: a potential regulatory role for mitochondrial aconitase

Background Obesity is an independent risk factor for cardiovascular disease and Type 2 diabetes, a condition that enhances the risk for various cardiomyopathies. Obesity is known to induce a state of metabolic inflexibility within the heart characterized by increased mitochondrial reliance on fatty acids for energy production. While the molecular mechanisms are not fully clarified, these change...

Diabetic Encephalopathy Affects Mitochondria and Axonal Transport Proteins

Introduction: Diabetic encephalopathy is described as any cognitive and memory impairments and associated with hippocampal degenerative changes, include neurodegenerative process and decreased number of living cell. Mitochondrial Diabetes (MD) appears fallowing activation of mutant mitochondrial DNA and is combination of diabetes and cognitive deficit. In this research we showed the correlation...
