Background: Adipose tissue dysfunction occurring in obesity leads to a low grade chronic inflammatory state. Fat tissue from obese individuals has a high infiltration rate of macrophages contributing to the development of obesity-related inflammation. At the cellular level, inflammation can be triggered by the activation (phosphorylation) of NF-κB as well as JNK. On the other hand, palmitic acid (PA) is a saturated fatty acid found elevated in plasma from obese subjects a...

Background: Obesity is strongly associated with a state of chronic low grade systemic inflammation and insulin resistance (IR). IR at the molecular level may be defined as a diminished activation of the metabolic phosphatidylinositol-3-kinase (PI3K)/Akt pathway of insulin. On the other hand, inflammatory response may be activated by NF-κB. Subject with obesity have elevated plasma levels of saturated fatty acids, such as palmitic acid (PA), which triggers insulin and infl...

Context: Insulin resistance is an important component of polycystic ovary syndrome (PCOS). Local cytokine production in adipose tissue increases local insulin resistance. The effect of testosterone on local adipose tissue cytokine production has not been explored thoroughly.Aim: To evaluate cytokine expression in subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from PCOS and control women and evaluate the response to testosterone on th...
