BACKGROUND Aldosterone synthase (CYP11B2) T-344C gene polymorphism was found to be correlated with atrial fibrillation (AF) risk. However, the results of individual studies remain conflicting. OBJECTIVE AND METHODS A meta-analysis including 2,758 subjects from six individual studies was performed to explore the correlation between CYP11B2 T-344C gene polymorphisms and AF. The pooled odds rati...

BACKGROUND Matrix metalloproteinase (MMP)-9 is excessively expressed in frail region of atherosclerotic plaque and released in circulation following plaque rupture. High MMP-9 level associated with severity of occluded thrombus and subsequent myocardial infarction. MMP-9 (-1562C>T) polymorphism associated with acute myocardial infarction, however conflicting data present regarding impact of MMP...

Background: The transforming growth factor-β1 (TGF-β1) gene -509C/T polymorphism has been suggested to be associated with increased coronary artery disease (CAD) risk. However, the individual studies results are still inconsistent. Objective and methods: To investigate the relationship between TGF-β1 gene -509C/T polymorphism and CAD, a meta-analysis involving 11,701 participants from 8 individ...

PURPOSE Studies investigating the associations between aldose reductase (ALR) genetic polymorphisms and diabetic retinopathy (DR) have reported controversial results. Therefore, to shed light on these inconclusive findings, we performed this meta-analysis to clarify the effects of ALR C(-106)T polymorphism on DR risk. METHODS Relevant studies were selected through an extensive search of PubMe...

Numerous studies have investigated the risk of cancer associated with the polymorphism of p21 3' UTR (rs1059234 C > T), but results have been inconsistent. We performed this meta-analysis to drive a more precise estimation of the association between this polymorphism and risk of cancer. A comprehensive search was conducted to identify all case-control studies of the rs1059234 C > T polymorphism...

background:  multiple  sclerosis  (ms) is a  chronic inflammatory  demyelinating  and  neurodegenerative disease  of central  nervous  system  with unknown  causes. etiology of ms involves  both  genetic  and  environment factors.  the  interleukin  7   receptor   (il7r)   gene   is  a promising candidate  for ms, because its involvement in the autoimmunity, regulation of the t-cell homeostasis...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a type of hereditary stroke and dementia. More than 90% of patients with CADASIL have mutations in the Notch3 gene. All mutations either create or destroy a cysteine residue in the epidermal growth factor-like repeats. In addition, five polymorphisms, which lead to amino acid substitutions, h...

OBJECTIVE A novel T-77C polymorphism in the promoter region of the DNA repair gene X-ray cross-complementing group 1 (XRCC1) may modulate its transcription to increase the risk of lung cancer. Here, we attempt to clarify: (i) whether the XRCC1 T-77C polymorphism was associated with lung cancer risk in Taiwanese and (ii) whether this polymorphism could act as a prognostic indicator to predict th...
