BACKGROUND The Transforming growth factor-β1 (TGFβ1) 869C/T polymorphism was associated with radiation pneumonitis (RP) susceptibility. However, the results remained controversial. Thus, a meta-analysis was conducted. METHODS Relevant studies were systematically searched by using the NCBI, Medline, Web of Science and Embase databases. Summary odds ratios (ORs) and corresponding 95% confidence...

OBJECTIVE The study aimed to investigate the association between polymorphism of I-FABP gene and coronary heart disease (CHD). METHODS 225 patients with CHD were randomly recruited into the case group, and 196 healthy elderly volunteers were recruited from Medical Examination Center of our hospital as control. General clinical data were collected and plasma TC, TG, LDL-C, HDL-C levels were me...

BACKGROUND Nitric oxide (NO) is a mediator of immunity to malaria, and genetic polymorphisms in the promoter of the inducible NO synthase gene (NOS2) could modulate production of NO. We postulated that NOS2 promoter polymorphisms would affect resistance to severe malaria. METHODS We assessed genomic DNA from healthy children and from those diagnosed with malaria from Tanzania (n=47 and n=138,...

Several studies have investigated the correlation between adiponectin gene rs22411766 T>G polymorphism and ischemic stroke risk. However, the results were not conclusive with each other. Therefore, to overcome this obstacle, we performed this meta-analysis to further explicate the adiponectin gene rs22411766 T>G polymorphism and ischemic stroke susceptibility. Case-control or cohort studies foc...

The diacylglycerol acyltransferase 1 gene (DGAT1) was identified as a strong candidate gene affecting mutton quality traits in sheep. Single nucleotide polymorphism creates a single base mutation (C to T) in AGCT site of endonuclease AluI. DGAT1 is one of the candidate genes to improve carcass characteristics in feedlot animals. In order to study area T487C in exon 17 of the DGAT1 polymorphism,...

BACKGROUND The cluster of differentiation antigen 14 (CD14) gene-159C/T polymorphism has been implied to be associated with coronary artery disease (CAD) susceptibility. However, the separate studies results are still conflicting between each other. OBJECTIVE AND METHODS To investigate the relationship between CD14 gene-159C/T polymorphism and CAD, a meta-analysis including 4467 subjects from...

Investigation of the mechanisms of phenotypic realization of allelic polymorphism of the eNOS gene has shown that the level of eNOS mRNA and activity of this enzyme in platelets depends from genotype. We identified a T(-786)-->C polymorphism in the promoter region, a variable number of tandem repeats (4a/4b) in intron 4 and the G(894)-->T polymorphism in exon 7 of the eNOS gene in isolated huma...

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...
