asthma is a chronic inflammatory and remodeling disorder of the airways, in which many cells, cellular elements, and cytokines play important roles. the role of tumor necrosis factor- α (tnf-α) in asthma is unclear in pakistani population. the aim of this study was to assess the relationship between tnf-α -308 polymorphism and asthma.polymorphism of tnf-α (g-308-a locus; rs 1800629) in 329 asth...

Objective: Tumour necrosis factor (TNF)-alpha, a prototype proinflammatory cytokine, has been implicated as an important pathogenic mediator in a variety of liver conditions. Some genetic polymorphisms in the human TNF-alpha promoter region, such as the G-A transitions -308 and – 238, have been shown to influence TNF-alpha expression in chronic hepatitis C virus infection. Aim of the work: The ...

PURPOSE TNF-alpha has been suggested to participate in the pathogenesis of exfoliation glaucoma (XFG). The purpose of the present study was to investigate a hypothesized association between two common functional polymorphisms in the promoter region of the TNF-alpha gene (TNF-alpha -308 G>A, rs1800629, and TNF-alpha -238 G>A, rs361525) and the presence of XFG in a Caucasian population. METHODS...

BACKGROUND Genes encoded within the MHC complex on chromosome 6 are thought to play an important role in the pathogenesis of psoriasis. A potential candidate is tumor necrosis factor alpha (TNF-alpha) gene. Psoriasis features an increased activity of the proinflammatory cytokine TNF-alpha in affected lesions. TNF-alpha promoter region contains several polymorphisms, including G/A transition at ...

OBJECTIVES TNF-alpha is a critical cytokine produced by Th1 cells while altered T helper 1 (Th1)-Th2 balance is found crucial for a successful pregnancy. STUDY DESIGN A cohort of 132 Southern Chinese Han RSA patients and 152 controls constituted the subjects of this study. Two functional polymorphisms -308 and -238 of TNF-alpha were studied by association analysis. RESULTS lack of associati...

Tumor necrosis factor (TNF) alpha-308 and interleukin (IL)-10(-1082) have potent inflammatory responses in the process of airway inflammation in asthma. The purpose of this study was to check for association of polymorphisms related to cytokine genes with susceptibility and severity of bronchial asthma in Egyptian children. Blood samples of 69 asthmatic children receiving treatment and follow-u...

Tumour necrosis factor (TNF)-alpha is associated with childhood wheezing. A genetic predisposition to increased TNF-alpha production, influenced by single nucleotide gene polymorphisms, may be important. Frequencies of TNF-alpha-308G/A and lymphotoxin (LT)-alpha+252G/A polymorphisms were compared in 115 asthmatic children, 55 wheezy infants and 156 control school children from the UK. Genotype ...

The aim of the study was to assess chosen factors of genetic susceptibility to DMT1: DRB1, DQB1, and TNF-alpha polymorphisms-308 (G/A) in children with DMT1 and their up-to-now healthy siblings. Then we tested whether the association between TNF-alpha genes and DMT1 is independent of HLA. 87 diabetic children, their 78 siblings, and 85 persons from healthy control group were followed up. The hi...

We present a meta-analysis of independent studies on the potential implication in the occurrence of coronary heart disease (CHD) of the single-nucleotide polymorphism (SNP) at the -308 position of the tumor necrosis factor alpha (TNF-alpha) gene. We use Bayesian analysis to integrate independent data sets and to infer statistically robust measurements of correlation. Bayesian hypothesis testing...
