Methods： Polymerase chain reaction-restriction fragment length polymorphism （PCR-RFLP） was performed to analyze NQO1 C609T polymorphism from 160 healthy controls and 76 colon cancer patients. Results： Among the colon cancer patients, the incidence of NQOI T allele （53.29%） was significantly higher than it in control group （33.75%, P〈0.001）. The individuals with NQO1 T allele had higher risk [2.239 （95% CI： 1.510-3.321） times] to develop colon cancer than individuals with NQO1 C allele. The incidence of NQO1 （TFI-） （34.21%） in colon cancer patients was higher than that in control group （15.62%, P〈0.001）. Odds ratios （OR） analysis suggested that NQO1 （T/F） and NQOI （T/C） genotype carriers had 3.813 （95% CI： 1.836-7.920） times and 2.080 （1.026-4.219） times risk compared with wild-type NQO1 （C/C） gene carriers in developing colon cancer. Individuals with NQO1 （T/I＇） genotype had 2.541 （95% CI： 0.990-6.552） times, 3.713 （95% CI： 1.542-8.935） times, and 3.471 （95% CI： 1.356-8.886） times risk than individuals with NQOI （T/C） or NQOI （C/C） genotype in well- differentiated, moderately-differentiated, and poorly-differentiated colon cancer patients, respectively. Conclusions： NQO1 gene C609T could be one of risk factors of colon cancer in farmers from western region of Inner Mongolia,展开更多
