Myeloid Cell-Restricted Insulin Receptor Deficiency Protects Against Obesity-Induced Inflammation and Systemic Insulin Resistance
A major component of obesity-related insulin resistance is the establishment of a chronic inflammatory state with invasion of white adipose tissue by mononuclear cells. This results in the release of pro-inflammatory cytokines, which in turn leads to insulin resistance in target tissues such as skeletal muscle and liver. To determine the role of insulin action in macrophages and monocytes in ob...
متن کاملHSP72 protects against obesity-induced insulin resistance.
Patients with type 2 diabetes have reduced gene expression of heat shock protein (HSP) 72, which correlates with reduced insulin sensitivity. Heat therapy, which activates HSP72, improves clinical parameters in these patients. Activation of several inflammatory signaling proteins such as c-jun amino terminal kinase (JNK), inhibitor of kappaB kinase, and tumor necrosis factor-alpha, can induce i...
متن کاملSmad3 Deficiency in Mice Protects Against Insulin Resistance and Obesity Induced by a High-Fat Diet
OBJECTIVE Obesity and associated pathologies are major global health problems. Transforming growth factor-β/Smad3 signaling has been implicated in various metabolic processes, including adipogenesis, insulin expression, and pancreatic β-cell function. However, the systemic effects of Smad3 deficiency on adiposity and insulin resistance in vivo remain elusive. This study investigated the effects...
متن کاملAdipose-Specific Deficiency of Fumarate Hydratase in Mice Protects Against Obesity, Hepatic Steatosis, and Insulin Resistance
Obesity and type 2 diabetes are associated with impaired mitochondrial function in adipose tissue. To study the effects of primary deficiency of mitochondrial energy metabolism in fat, we generated mice with adipose-specific deficiency of fumarate hydratase (FH), an integral Krebs cycle enzyme (AFHKO mice). AFHKO mice have severe ultrastructural abnormalities of mitochondria, ATP depletion in w...
متن کاملAdenylyl Cyclase Type 5 Deficiency Protects Against Diet-Induced Obesity and Insulin Resistance
Adenylyl cyclase type 5 knockout (AC5KO) mice have increased longevity and share a similar phenotype with calorie-restricted wild-type (WT) mice. To determine the in vivo metabolic properties of AC5 deficiency, we compared the effects of standard diet (SD) and high-fat diet (HFD) on obesity, energy balance, glucose regulation, and insulin sensitivity. AC5KO mice on SD had reduced body weight an...
