Introduction: Insulin resistance is a main characteristic of polycystic ovary syndrome (PCOS) and contributes to the increased risk of type 2 diabetes and cardiovascular disease. It is thought that in PCOS there is an alteration in the insulin signaling pathway. An important kinase in this pathway is the phosphatidylinositol 3 kinase (PI3K), the activity of which has been found to be decreased in PCOS. Based on this observation we investigated whether a single nucleotide polym...

Introduction: Klotho has an important role in insulin signaling and the development of ageing-like phenotypes in mice. Recently, the G-395A polymorphism in the promoter region of the human klotho gene has been reported to affect promoter function. It has been also shown to be an independent genetic risk factor for atherosclerotic cardiovascular disease. The aim of this study was to examine the possible role of this polymorphism in the metabolic syndrome....

Background of study: Twin studies have shown that age at menarche may be subject to hereditary influences but the specific determinants are unknown. Estrogens are known to have an important role in menarche. Since aromatase is responsible enzyme for the conversion of androgens to estrogens, the aromatase (CYP19) gene could be a candidate gene for the regulation of menarche. The aim of this study was to investigate the possible association of the CYP19(TTTA)n poly...
