| 摘 要： | 目的探讨子宫内膜癌中p16基因状态对端粒酶活性的影响。方法用PCR技术检测癌组织中p16基因的纯合性缺失及第一外显子异常甲基化,用原位杂交法检测端粒酶的表达。结果36例癌组织中,9例发生p16基因缺失,12例发生甲基化,未发现基因缺失与甲基化同时存在的病例;29例内膜癌端粒酶表达阳性,阳性率为80.56%。9例基因缺失标本中均有端粒酶的阳性表达,p16甲基化与否对端粒酶的表达影响无差异,但端粒酶阳性率在p16基因失活组明显高于p16基因未失活组。结论p16基因失活可以导致激活端粒酶端粒,p16基因失活的不同状态端粒酶激活的影响存在差异。

| Abstract: | Objective To study the effect of MTS1/p16 gene deletion and 5 CpG island methylation on the expression of telomerase activity in endometrial carcinoma.Methods The p16 gene deletion and 5’CpG island methylation were determined by PCR technique, The telomerase catalytic protein subunit mRNA was assessed by in situ hibridization method.Results The p16 gene deletion and 5’CpG island methylation rates in endometrial carcinoma were 25.00% (9/36)and 33.33% (12/36) respectively. The telomerse expression rate was 80... |
