Abstract:
Objective To evaluate the relationship between the CCNE1 or RIP2, identified at a single nucleotide poly?morphism, and the risk, clinic stage and pathological grade of bladder cancer. Methods Peripheral venous blood samples were obtained from 176 patients with bladder cancer and 210 controls without cancer. DNA was extracted. Polymerase chain reaction (PCR) method was used to detect CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism. According to the postoper?ative pathological results, patients with bladder cancer were determined the grading and staging. The genotype differences of medium gene and the distribution gene were analyzed and compared in bladder cancer group and control group. The relation?ship of CCNE1 (rs8102137) and RIP2 (rs42490) genotypes and clinical data of patients with bladder cancer was analyzed, and the relationship of them with the genetic susceptibility to bladder cancer was also analyzed. Results The genotype dis?tribution was with good group representative in control group. The frequency of CCNE1(rs8102137) variant allele was signifi?cantly higher in bladder cancer group (40.91%) than that of control group (30.95%,OR=1.54,95%CI:1.02-2.45, P<0.05). The frequency of RIP2 (rs42490) variant allele was significantly higher in bladder cancer group (72.73%) than that of control group (62.38%, OR=1.61, 95%CI:1.04-2.48, P<0.05). There were no significant differences in gene polymorphisms of CC?NE1(rs8102137) and RIP2 (rs42490) between different pathological grades and different clinical stages of bladder cancer. Conclusion The CCNE1 (rs8102137) and RIP2 (rs42490) polymorphism have interaction in occurrence of bladder cancer process. There is higher risk of bladder cancer in individuals carrying mutant alleles than that of individuals carrying wild type.
