【 摘 要 】

Objective: Multi-drug resistance gene 1 (ABCB1) is closely related to bowel diseases. Therefore, our study was aimed to evaluate the correlation between ABCB1 polymorphisms (C1236T and C3435T) and ulcerative colitis (UC) susceptibility. Methods: A total of 61 UC patients and 64 healthy people participated in the study. Genotyping was conducted with the method of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). χ2 test was used to evaluate the association of ABCB1 gene polymorphisms (C1236T and C3435T) and UC susceptibility. Results: For ABCB1 C1236T polymorphism, the frequencies of CC genotype and C allele were found higher in the cases than those in the controls (CC: 36.1% vs. 20.3%; C: 58.2% vs. 41.4%), which indicated that the CC genotype and C allele might increase the risk for UC (OR = 3.39, 95% CI = 1.28-8.97; OR = 1.97, 95% CI = 1.19-3.26). However, there were no statistical differences in the genotype or allele distribution of ABCB1 C3435T between the case and control group. Conclusion: The CC genotype and C allele of ABCB1 C1236T polymorphisms are significantly associated with UC susceptibility, so we conclude that ABCB1 C1236T polymorphisms might serve as genetic-susceptibility factors for UC. While, no remarkable relationship is observed between ABCB1 C3435T polymorphisms and UC.
