BRM基因多态与食管鳞状细胞癌易感性的关联研究

    Association between single nucleotide polymorphisms in BRM and the susceptibility of esophageal squamous cell carcinoma

    • 摘要: 目的:研究BRM-741位点和BRM-1321位点的插入/缺失多态与中国汉族人群食管鳞状细胞癌(ESCC)易感性的关系。方法:采用病例-对照研究,以聚合酶链反应-聚丙烯酰胺凝胶电泳的方法,分析343例ESCC患者和362名性别、年龄等人口学特征与病例频数匹配的健康对照者的BRM-741以及BRM-1321基因型分布情况。logistic 回归分析BRM基因多态与ESCC易感性的关系。结果:BRM-741多态与ESCC的患病风险无相关性(P>0.05),而BRM-1321多态与ESCC的发生有相关性(P<0.01)。携带BRM-1321插入/插入基因型的个体发生ESCC的风险较携带BRM-1321缺失/缺失基因型者增加了94.0%(OR=1.94,95%CI=1.11~3.38)。与缺失型等位基因比较,插入型等位基因增加了35.0%的ESCC易感性(OR=1.35,95%CI=1.07~1.71)。结论:BRM-1321多态与中国汉族人群ESCC遗传易感性有关,BRM-741基因多态与中国汉族人群ESCC的患病风险无关。

       

      Abstract: Objective: To investigate the association of indel polymorphisms of BRM-741 and BRM-132 with the susceptibility of esophageal squamous cell carcinoma (ESCC) in Chinese Han population. Methods: The genotype distribution of BRM-741and BRM-1321 in 343cases of ESCC and 362 healthy controls whose gender, age and other demographic characteristics were matched with the frequency of the ESCC cases was analyzed in a case-control study by using polymerase chain reaction-polyacrylamide gel electrophoresis method. Logistic regression model was used to evaluate the association between polymorphisms and ESCC susceptibility. Results: There was no significant association between BRM-741 and ESCC(P>0.05). However, there was a significant association between BRM-1321 and ESCC susceptibility(P<0.01). The insertion/insertion genotype was associated with an increased risk of ESCC compared with the deletion/deletion genotype of BRM 1321 (OR=1.94, 95%CI=1.11-3.38). The insertion allel was associated with an increased risk of ESCC compared with the deletion allel of BRM 1321 (OR=1.35, 95%CI=1.07-1.71). Conclusions: The polymorphism in BRM-1321 is associated with ESCC susceptibility, but no significant association is observed between the polymorphism in BRM-741 and ESCC incidence in Chinese Han population.
