ABSTRACT
AIM:
Bladder cancer is the sixth most common cancer worldwide and its incidence is particularly high in many developed regions including southwestern Taiwan. However, the genetic contribution to the etiology of bladder cancer is not well-understood. The aim of this study was to evaluate the association of the enhancer of zeste homolog 2 (EZH2) genotypes with Taiwan bladder cancer risk. MATERIALS ANDMETHODS:
Three polymorphic variants of EZH2 were analyzed regarding their association with bladder cancer risk, and three hundred and seventy-five patients with bladder cancer and same number of age- and gender-matched healthy controls recruited were genotyped by the PCR-RFLP method.RESULTS:
Among the three polymorphic sites examined, the genotypes of EZH2 rs887569 (C to T), but not rs41277434 (A to C) or rs3757441 (T to C), were positively associated with bladder cancer risk (p for trend =0.0146). Individuals with the EZH2 rs887569 TT genotypes were associated with decreased cancer risk than those with wild-type CC genotype. The stratified analyses showed that EZH2 rs887569 TT genotypes had protective effects on non-smokers but obviously not on smokers.CONCLUSION:
Our findings provide evidence that the T allele of EZH2 rs887569 may be associated with the lower risk of bladder cancer development, especially among non-smokers.Palavras-chave
