Lack of association between TNF-alpha promoter polymorphism and prostate carcinoma susceptibility in eastern Croatian population.

A single nuclear polymorphisms (SNPs) in the promoter region of the tumor necrosis factor-alpha (TNF-alpha) gene are involved in regulation of expression levels of TNF-alpha and therefore are associated with oncogenesis of several cancers. Aim of our study was to investigate the effect of G--->A polymorphism at -308 position in the promoter region of the TNF-alpha gene on prostate cancer (CalphaP) susceptibility in a subset of patients from Eastern Croatia. Study population consisted of 240 patients (120 with CalphaP, 120 controls).
