TO THE EDITOR: I read with great interest the paper from the Kim et al on the G-protein beta3 subunit (GNβ3) C825T polymorphism with overlap syndrome of functional dyspepsia (FD) and irritable bowel syndrome (IBS) which demonstrated that no apparent association of the GNβ3 C825T polymorphism with FD, IBS or the overlap of FD and IBS existed. However, a recent study on Korean children showed the...

Single nucleotide polymorphism C825T located within the GNB3 gene has been proposed in the literature as the performance enhancing polymorphism in highly trained athletes. Therefore, the aim of the present study was to verify the hypothesis assuming an association between the C825T polymorphic site and performance of competitive swimmers. The frequencies of C/T alleles and distribution of CC, C...

BACKGROUND/AIMS Guanine nucleotide binding protein (G-protein) beta polypeptide 3 (GNB3) C825T polymorphism alters intracellular signal transduction, which may lead to motor or sensory abnormalities of the gastrointestinal tract. The aim of the present study was to evaluate the association of the GNB3 C825T polymorphism with susceptibility to overlap syndrome of functional dyspepsia (FD) and ir...

PURPOSE The association between GNB3 C825T polymorphism and cancer risk has been investigated. However, results remain inconclusive. In this study we aimed to obtain a more precise estimation of this association. METHODS A meta-analysis of 8 eligible studies including 1,812 cancer cases and 3,731 controls was conducted with odds ratios (ORs) and the corresponding 95% confidence interval (95% ...

Recently a novel C825T polymorphism in the G protein beta3 subunit gene was identified that showed an association with hypertension in a German population; the results of studies in other populations have been inconsistent. To examine the contribution of GNB3 polymorphisms to the development of hypertension in the northern Chinese Han population, we conducted a case-control study consisting of ...

PURPOSE The G-protein β3-subunit gene C825T polymorphism (GNB3-C825T) has been reported to be associated with essential hypertension (EH), but results from previous studies are conflicting. The present study aimed at investigating the association between this polymorphism and risk of EH using a meta-analysis on the published studies. MATERIALS AND METHODS PubMed, Embase, CBM (China Biological...

From epidemiological evidence a high salt diet is a risk factor for gastric cancer, independent of Helicobacter pylori infection, and animal studies have shown that salt promotes carcinogenesis. The G-protein β 3(GNB3) C825T polymorphism has been linked with hypertension, salt sensitivity and multiple diseases. Our aim in this study was to clarify any association of the GNB3 C825T polymorphism ...

Several studies have reported an association between GNβ3 C825T polymorphism and irritable bowel syndrome (IBS). However, the results remain inconclusive and controversial, particularly for the data derived from different ethnicities and IBS subtypes. Therefore, we performed an updated meta-analysis to evaluate this association. All eligible case-control studies that met the search criteria wer...

Acute myocardial infarction is a highly prevalent cardiovascular disease in Taiwan. Among several etiological risk factors, obesity and inflammation are strongly associated with the frequency of hypertension, cardiovascular disease, diabetes, and myocardial infarction. To discriminate obesity- and inflammation-related genes and the onset of acute myocardial infarction (AMI), a case-control stud...
