Association of VNTR polymorphism of tumor necrosis factor receptor 2 (TNFRSF1B) with pulmonary tuberculosis
نویسندگان
چکیده
This study was designed to find out the impact of the variable number of tandem repeats (VNTR) of the tumor necrosis factor receptor 2 (TNFRSF1B) on pulmonary tuberculosis (PTB) risk in an Iranian population. This case-control study was done on 159 PTB patients and 158 healthy subjects. Bi-allelic TNFRSF1B VNTR was genotyped by polymerase chain reaction. Logistic regression analysis revealed no significant association between TNFRSF1B VNTR and PTB risk (P>0.05). Our findings proposed that TNFRSF1B VNTR polymorphism is unlikely to confer susceptibility to PTB.

Pulmonary tuberculosis, is a granulomatous disease of the lungs that caused by Mycobaterium tuberculosis. A number of genes have been identified in studies of diverse origins to be important in tuberculosis. Out of which the tumor necrosis factor α (TNF-α) gene has been identified to plays a major role in the initial and long-term control of tuberculosis. In this study, the TNF-α gene at -238, ...
متن کاملTUMOR NECROSIS FACTOR ALPHA (TNF-a)
Tumor necrosis factor alpha (TNF, TNFSF2) is an important multifunctional cytokine that regulates inflammation, host defense, immune responses, and apoptosis. TNF exists as a membrane-bound 26kDa, type II integral membrane protein, and a 17kDa soluble homotrimeric TNF that is generated via proteolytic cleavage by TNF-a converting enzyme (TACE, ADAM17). Both the membrane-bound and soluble forms ...
متن کاملEvaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...

BACKGROUND The interaction of tumor necrosis factor-α (TNF-α) with its receptors: TNFRSF1A and TNFRSF1B is critical for the promotion of tumor growth, invasion and metastasis. To better understand the roles of single nucleotide polymorphisms (SNPs) in the TNF-α, TNFRSF1A and TNFRSF1B genes in the development of breast cancer, we explored the associations between SNPs in these three genes and br...
