Introduction: A common polymorphism 4G/5G in the promoter region of the Plasminogen activator inhibitor-1 (PAI-1) gene has been reported to influence the expression levels of PAI-1. According to the evidence, progression of breast cancer can be associated with elevated levels of PAI-1, it seems that evaluation of a possible correlation between the polymorphism and clinical status of breast canc...

Introduction: Infertility is described as the inability to get pregnant after one year of unprotected intercourse. About half of infertility cases are because of male factors. Idiopathic azoospermia or severe oligozoospermia caused by genetic alterations is a significant part of male infertility. A key step of spermatogenesis is crossover events during meiotic reciprocal recombination. MLH3 pro...

Introduction: Leptin, the obese (ob) gene product, is a cytokine-like hormone secreted mainly from adipose tissue acting on a receptor site in the hypothalamus to inhibit food intake and stimulate energy expenditure. A G-2548G polymorphism in the leptin gene promoter has a strong influence on leptin gene expression and adipose tissue secretion. The aim of this study was to examine the associati...
