目的:探讨细胞色素P4501A1(CYP1A1)酶的基因多态与肾癌易感性的关系。方法:采用病例对照设计,以175名肾癌患者为病例组,200名未患任何肿瘤的健康人为对照组。应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术,检测CYP1A1基因A4889G(M2)、C4887A(M4)的多态性。 结果:病例组M2、M4各基因型分布与对照组相比无统计学差异。携带M2/M2基因型者与肾癌的发生呈正相关(OR=2.225,95%CI:1.134~4.365,P=0.020)。结论:CYP1A1基因M2/M2基因型可能是肾癌的遗传危险因素。 |

Abstract: |
Objective:To evaluate the relationship between the polymorphism of CYP1A1 gene and the genetic susceptibility to renal cancer.Methods: A case-control study was conducted in 175 renal cancer patients and 200 healthy control subjects to investigate the role of CYP1A1 gene A4889G(M2) and C4887A(M4) polymorphisms in renal cancer.PCR-RFLP was used to identify the genotypes of polymorphism.Results: The frequencies of A4889G and C4887A genotypes were not significantly different between RCC cases and healthy controls.M2/M2 genotype was positively correlated with the incidence of renal cancer (OR=2.225 \[95%CI=1.134-4.365,P=0.020\]).Conclusion: M2/M2 genotype of CYP1A1 gene may be a risk factor for renal cancer. |
