OBJECTIVE: There is a need for a simple and accurate method for the assessment of cardiovascular risk in polycystic ovary syndrome (PCOS). Lipid accumulation product (LAP) is based on the assessment of waist circumference and serum triglycerides that yield an estimation of lipid overaccumulation. We aimed to determine whether LAP is associated with metabolic syndrome (MetS) in Caucasian women with...
Polycystic ovary syndrome (PCOS) is associated with an altered plasma lipid profile and increased risk for cardiovascular diseases. We hypothesized that molecular mechanisms underlying cardiac pathology in PCOS involve changes in expression and subcellular localization of several key proteins involved in cardiac lipid transport and metabolism, such as fatty acid transporter CD36, lipin 1, peroxisome...
OBJECTIVE: Most women with PCOS have increased adrenal androgen production, enhanced peripheral metabolism of Cortisol and elevation in urinary excretion of its metabolites. Increased Cortisol clearance in PCOS is followed by a compensatory overdrive of the hypothalamic-pituitary-adrenocortical (HPA) axis. We hypothesized that oral contraceptives containing ethinylestradiol and drospirenone (EE-DRSP)...
OBJECTIVE: In order to gain deeper insight into molecular mechanisms underlying oxidative stress (OS) and its relation to insulin resistance and hyperandrogenemia, plasma markers of OS and antioxidant glutathione-peroxidase (GPX) activity were studied in non-obese polycystic ovary syndrome (PCOS) women via the oral glucose tolerance test (OGTT) and hyperinsulinemic euglycemic clamp. DESIGN: In 36...
It is supposed that women with polycystic ovary syndrome (PCOS) are prone to develop cardiovascular disease as a consequence of multiple risk factors that are mostly related to the state of insulin resistance and consequent hyperinsulinemia. In the present study, we evaluated insulin signaling and glucose transporters (GLUT) in cardiac cells of dihydrotestosterone (DHT) treated female rats as an animal...
