宫颈癌p53外显子7突变与HPV感染的关系

Relationship between p53 (exon 7) mutation and HPV infection in human cervical cancers

  • 摘要: 目的 探讨p5 3外显子 7突变与HPV1 6、1 8型感染在宫颈癌发生中的作用及相互关系。方法 采用聚合酶链反应 (PCR)、单链构象多态性 (SSCP)、限制性酶解片段长度多态性 (RFLP)分析等方法对 49例宫颈癌组织石蜡包埋标本中p5 3外显子 7的突变与HPV1 6、1 8型感染进行了检测。结果 p5 3外显子 7的突变率 1 0 .2 0 %, HPV DNA阳性率 87.76%, 二者差异显著 (χ2 =5 5 .90 1, P <0 .0 0 1 ), 突变位点多见于密码子 2 2 9(1 /5 )、2 47(2 /5 )、2 49(1 /5 ) ;HPV1 6 DNA阳性率 87.76%显著高于HPV1 8 DNA阳性率 3 8.78%(χ2 =2 3 .2 2 7,P <0 .0 0 1 ) ;p5 3外显子 7突变与HPV感染可共存于同一标本中。结论 宫颈癌p5 3外显子7突变热点是密码子 2 2 9、2 47、2 49;少数宫颈癌是由于 p5 3外显子 7突变或 p5 3外显子 7突变与高危HPV感染相互作用所致, 大多数宫颈癌是由于高危HPV感染尤其是HPV1 6感染所致

     

    Abstract: Objective To investigate the relationship between p53 (exon 7) mutations and human papillomavirus (HPV) 16?18 infections in human cervical cancer. Methods p53 (exon 7) mutations and HPV16?18 infections were examined by polymerase chain reaction (PCR) and single strand conformation polymorphism (SSCP) and restriction fragment length polymorphism(RFLP) analysis in the 49 cervical cancers. Results Significant difference (χ 2 =55.901, P <0.001) between p53 (exon7) mutations 5/49 (10.20%) and HPV in...
