摘要 目的:研究O6-甲基鸟嘌呤-DNA甲基转移酶(O6-methylguanine-DNA methyltransferase,MGMT)在肝癌组织中的表达及其与p53的相关性。方法:采用RT-PCR的方法检测40例肝癌组织中MGMT基因的表达水平,并采用免疫组织化学方法检测肝癌组织中p53蛋白的表达。结果:40例肝癌组织中有28例MGMT的表达水平明显低于对照非肝癌组织中,其MGMT mRNA表达的相对量为0.54±0.13,而非肝癌组织组为1.15±0.095。结论:p53蛋白的表达与细胞中MGMT基因的表达有一定的相关性。 Objective :To explore the expression of MGMT in hepatoeellular carcinoma and the relation between the MGMT and p53. Methods: The exprssion level of MGMT were measured by RT - PCR, and then p53 protein was detected by immunohistoehemistry. Results: Total of 28 cases showed lower levels of MGMT gene in hepatoceUular carcinoma group compared with normal liver. Conclusion: There was correlation between p53 and MGMT gene ex- pression.
