Association between tumor necrosis factor-alpha gene rs1800629 (-308G/A) and rs361525 (-238G > A) polymorphisms and prostate cancer risk in an Iranian cohort.

Association between tumor necrosis factor-alpha gene rs1800629 (-308G/A) and rs361525 (-238G > A) polymorphisms and prostate cancer risk in an Iranian cohort

 
BACKGROUND:
Prostate cancer (PCa) as the first men's common cancer in the world and the third cancer in Iranian men is a heterogeneous disorder which sometimes several biopsies are needed for its diagnosis.
 
OBJECTIVES:
The aim of current study is finding new biomarkers in order to diagnose of PCa at the earliest possible stage. Hence, the relationship between rs1800629 and rs361525 polymorphisms of TNF-α gene with PCa was investigated.
 
MATERIALS AND METHODS:
Blood DNA samples were collected from 100 patients with PCa, 110 with BPH, and 110 controls. Collected samples were examined using PCR-RFLP and Tetra-ARMS-PCR techniques to detect the desired polymorphisms.
 
RESULTS:
The frequency of rs1800629 genotypes in smokers was significantly different from non-smokers with PCa (p= 0.001). Logistic regression analysis results showed that GA heterozygotes in comparison to GG homozygotes had higher risk of developing Benign Prostatic Hyperplasia (BPH) or prostate cancer. However, no significant correlation was considered between the risk of PCa and the TNF-α gene polymorphisms (rs1800629 and rs361525).
 
CONCLUSIONS:
Although, the achieved results of this investigation demonstrated that the two examined genetic variants do not seem to be suitable markers for early diagnosis of prostate cancer in this pilot study; however increased risk for the disease is shown in GA heterozygotes and smokers which is indicative of some epigenetic factors influence on prostate cancer etiology.
