摘要:目的  分析子宫内膜癌I型和II型全基因表达谱。方法  利用6张Affymetrix全基因组基因芯片,分析两者之间在表达谱上的差异,结合生物信息分析。结果  许多基因明显在雌激素依赖型子宫内膜癌中高表达,其中,一些基因涉及了雌激素依赖型中雌激素的代谢与转化,另外一些基因可能为雌激素调节基因。CYP2C9参与了雌激素酮硫酸盐转化为16-羟基硫酸盐代谢;DDC能与类固醇受体结合,增强类固醇受体的转录活性。结论  某些基因在雌激素依赖型子宫内膜癌中高表达,为进一步研究此类基因在子宫内膜癌发病过程的作用及预后奠定了基础。

Abstract: Objective To study gene expression profiling in human type I and II endometrial carcinoma. Methods Six Affymetrix human genome genechips were utilized to investigate the differences in gene expression profiles between type I and II endometrial carcinoma with bioinformatic analysis. Results Many genes were highly expressed in estrogen-dependent endometrial carcinoma, and some of them were involved in the metabolism and conversion of estrogen, while some others in estrogen regulation. CYP
2C9, for instance, was involved in the conversion of estrogen sulfate to 16-hydroxy sulfate metabolite, DDC in estrogen-dependent patho
