| 摘 要： | 目的:研究宫颈癌肿瘤细胞多药耐药基因1(mdr1)甲基化与宫颈癌新辅助化疗疗效相关性,探索适用于预测临床化疗多药耐药性的敏感指标。方法:采用MassARRY EpiTYPER DNA甲基化分析技术定量分析宫颈鳞癌(n=40)新辅助化疗前后、正常对照组(n=30)中的mdr1基因启动子区15个CpG位点的甲基化状态。结果:新辅助化疗敏感组(n=31)CpG_2、3、4位点甲基化率高于行新辅助化疗耐药组(n=9),差异有统计学意义(p<0.05);与新辅助化疗前组相比,化疗后组CpG_7、CpG_8、CpG_12、13、CpG_18、CpG_19、20、CpG_23、CpG_24位点甲基化率减低,差异有统计学意义(p<0.05);与正常组织(n=30)相比,宫颈癌(n=80)CpG_2、3、4、CpG_5、CpG_6、CpG_7、CpG_8、CpG_9、10、CpG_12、13、CpG_18、CpG_19、20、CpG_22、CpG_23、CpG_24位点甲基化率较低,差异有统计学意义(p<0.05)。结论:宫颈癌mdr1基因甲基化水平高低与宫颈癌NACT疗效有一定相关性。 |
