BACKGROUND Hypoxia and nitric oxide (NO) play important roles in the onset and progression of glaucoma. Vascular endothelial growth factor (VEGF) is one of the main factors responsive to hypoxia and NO. In this study, we investigated the association between the BstUI C/T VEGF gene polymorphism and primary open angle glaucoma (POAG). METHODS 60 POAG patients and 78 healthy volunteers were enro...

The t-haplotype is a chromosomal region in Mus musculus characterized by meiotic drive such that heterozygous males transmit t-bearing chromosomes to roughly 90% of their offspring. Most naturally occurring t-haplotypes express a recessive embryonic lethality, preventing fixation of the t-haplotype. Surprisingly, the t-haplotype occurs in nature as a persistent, low-frequency polymorphism. Earl...

Background: Unexplained recurrent spontaneous abortion (URSA) has been suggested being associated with the failure of fetal-maternal immunologic tolerance in which the regulatory T lymphocytes (Tregs) play a crucial role. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is expressed transiently on activated T cells and constitutively on Tregs. CTLA-4 interacts with the B7 cell surface molec...

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...

PURPOSE To investigate whether associations with the nitric oxide synthase gene (NOS3) variants and risk of primary open-angle glaucoma (POAG) depend on female reproductive factors. METHODS Two functional and two tagging single nucleotide polymorphisms (SNPs; T-786C: rs2070744, Glu298Asp: rs1799983, rs7830, and rs3918188) were evaluated in a nested case-control study from the Nurses' Health S...

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...
