摘要:

目的:研究新疆维吾尔族女性乳腺癌的发生与人类白细胞抗原(HLA) DRB1等位基因多态性的关系,探讨乳腺癌的遗传易感性。方法:分别收集维吾尔族女性乳腺癌患者和健康人外周血标本196和230例,提取细胞基因组DNA,采用序列特异性引物聚合酶链反应(PCR- SSP)和毛细管电泳测序(CE)的方法进行HLA-DRB1基因多态性鉴定。结果:乳腺癌患者外周血DNA的HLA-DRB1*01多态性频率显著高于健康对照(χ2=10.180,OR=4.550,P<0.05),HLA-DRB1*16多态性低于对照(χ2=4.792,OR=0.492,P<0.05),而其他位点多态性两组间的差异无统计学意义(P>0.05)。结论:维吾尔族女性乳腺癌的发生可能与HLA-DRB1等位基因多态性存在密切关系,对于揭示乳腺癌发病机制及临床诊断提供了客观依据。

Abstract:

OBJECTIVE: To investigate the association of human leukocyte antigen(HLA) DRB1 gene polymorphisms with genetic susceptibility to breast cancer in Uyghur women. METHODS:Genomic DNA was isolated from peripheral blood of 196 patients with breast cancer and 230 healthy Uyghur women, HLA-DRB1 typing was performed by means of polymerase chain reaction-sequence-specific priming (PCR-SSP) and capillary electrophoresis sequencing (CE) method. RESULTS:The frequency of HLA-DRB1*01 genotype in breast cancer was significantly higher than in the control group (χ2=10.180, OR=4.550, P<0.05), while the frequency of HLA-DRB1*16 genotype was significantly lower than in the control group (χ2=4.792, OR=0.492, P<0.05). The frequencies of other HLA-DRB1 alleles did not show statistical significance between the two groups. CONCLUSION:Breast carcinogenesis in Uyghur women was closely associated with the allele polymorphisms of HLA-DRB1, which provides objective evidence for elucidating the molecular mechanism and clinical diagnosis for breast cancer.
