BACKGROUND Metabolic syndrome (MetS) is a serious public health problem. It is an important risk factor of cardiovascular disease in developed countries. Adipose tissue considered as an organ that releases a variety of molecules referred to adipocytokines such as leptin. Polymorphism of their related genes may play an important role in development of MetS. The aim of this study was to determine...

One of the five possible mechanisms of leptin resistance in human obesity is the defect in the leptin receptor (Ob-R). Evidence has accumulated that leptin-binding activity in human serum is related to a soluble form of the leptin receptor, and restriction of energy intake resulted a decrease in circulating leptin levels. Aim of this study is to examine the difference of serum soluble leptin re...

polymorphisms in the β subunit of the high affinity receptor for ige (fcεriβ) and interferon-γ (ifn-γ) genes may influence the risk of asthma. however, the results in asian population are still debatable. we performed a meta-analysis to ascertain the association between the fcεriβ e237g, fcεriβ -109c/t, and ifn-γ 874t/a polymorphisms and asthma in an asian population. databases including pubmed...

background and objective: host genetic factors such as cytokine gene polymorphisms as well as helicobacter pylori (h. pylori) infection have been found to be associated with gastric cancer risk . interleukin 1 is a pro-inflammatory cytokine involved in h. pylori-induced gastric inflammation. therefore, we analyzed the association between il-1β and il-1-rn polymorphisms and gastric cancer in per...

BACKGROUND Human obesity is due to a complex interaction among environmental, behavioral, developmental and genetic factors, including the interaction of leptin (LEP) and leptin receptor (LEPR). Several LEPR mutations and polymorphisms have been described in patients with early onset severe obesity and hyperphagic eating behavior; however, some contradictory findings have also been reported. In...

CONTEXT Complications of atherosclerosis are the leading cause of morbidity and mortality in industrialized societies. Obesity has emerged as an independent risk factor for complications of atherosclerotic vascular disease. Leptin, a hormone produced by the adipocyte, increases with obesity and appears to modulate energy balance and food intake. In addition, other actions of leptin have been pr...

OBJECTIVE Obesity is a complex heterogeneous disease that is caused by genes, environmental factors, and the interaction between the two. The leptin (LEP) and leptin receptor (LEPR) genes have been evaluated for polymorphisms that could potentially be related to the pathophysiology of obesity and its complications. The aim of this study was to investigate the role of LEP G2548A and LEPR 668A/G ...

objective(s):the aim of the study was to investigate the relationship between insulin resistance (ir) and leptin (lep) gene polymorphisms in peritoneal dialysis (pd) patients. materials and methods: from july 1, 2011 to august 1, 2011, patients who received chronic pd were chosen and divided into three groups (dm, high homr-ir, and low homr-ir). two pcr products of lep were sequenced and aligne...
