摘要: |
p53基因突变是肿瘤发生中的多发事件,导入野生型p53基因能抑制肿瘤细胞的生长。通过腺病毒载体介导,将野生型p53基因转导到人肺腺癌细胞系(GLC-82)中,证实对肺腺癌细胞生长具有明显的抑制作用,抑制率达61%。对GLC-82细胞系裸鼠皮下移植瘤进行治疗实验结果表明,p53能抑制肿瘤细胞体内的生长。流式细胞计数及DNA片段化分析显示,p53基因的转导能诱导肺腺癌细胞发生凋亡。研究结果提示,腺病毒能介导p53基因对肿瘤进行治疗,并可作为肿瘤外科手术、化疗、放疗外的又一治疗方法 |

Abstract: |
In our research,the wild-type p53 gene was transferred into human lung adenocarcinoma cell line(GLC-82)and reduced the growth of GLC-82 cells in vivo and in vitr(the inhibiting rate:6 1% and 42%).The other results demonstrated that adenovirus-mediated tran sfer and espression of the wild-type p53 in GLC-82 lacking ghe p53 g ene resulted in GLC-82 cells apoptosis which was indicated by FCM and DNA fragment analysis.These results can offer yome scientific evidence s for use of the wild-type. p53 gene to tumor gene therapy. |
