KCNJ11 as well as UCP2 genes are involved via modulation of ATP concentration in pancreatic beta-cells in control of insulin secretion. The aim of study was to compare genotypic distribution of E23K (KCNJ11) and G-866A (UCP2) polymorphisms between diabetics, their offspring and controls and to study the possible association of these polymorphisms with biochemical and anthropometric parameters.The study entered 302 diabetics, 165 offspring, 241 controls. ...

Introduction: The SNP rs7578597 (Thr1187Ala) of THADA gene was identified in GWA studies as a novel type 2 diabetes risk locus. Nevertheless, subsequent studies of this SNP effect have been inconclusive. In some studies, rs7578597 has been associated with insulin secretion but no significant correlation with type 2 diabetes has been reported. Product of THADA gene is considered to be involved in apoptosis. Whether rs7578597 affects insulin secretion throught the apoptosis of p...

The polycystic ovary syndrome (PCOS) is associated with features of the insulin resistance syndrome and altered glucose homeostasis. Factors that play an important role in these processes are still emerging. Adipokines and pro-inflammatory cytokines may be involved in development of insulin resistance in PCOS. The purpose of this study was to determine if a relationship exists between adiponectin, resistin, leptin, interleukin (IL) 4, IL6, IL10, tumor necrosis factor α (T...

SHBG (sex hormone-binding globulin) is a transport protein specific for dihydrotestosterone, testosterone and estradiol. The missense mutation in exon 8 (GAC→AAC) causing the amino acid exchange D327N correlates accordingly to literature data with higher SHBG levels.We studied the possible association of this polymorphism with polycystic ovary syndrome (PCOS) and its influence on anthropometric and biochemical parameters in 247 PCOS patients in com...

The A-3826G gene polymorphism of the uncoupling protein 1 (UCP1) causes the lower expression of UCP1 in visceral fat and reduced energy expenditure. Peroxisome proliferator activated receptor gamma 2 (PPARG2) plays a role in the regulation of the adipocyte differentiation and energy balance. The Pro12Ala polymorphism is associated with better insulin sensitivity. We compare the genotypic distribution of these polymorphisms in PCOS and controls and study their possible associat...
