    摘要: 目的:观察以RNA干扰技术沉默ID-1表达对人肝癌细胞HepG2裸鼠皮下移植瘤生长的抑制作用,探讨抑制ID-1表达对肝癌可能存在的抑癌作用。方法:向BALB/C-nu系雄性裸鼠皮下注射HepG2细胞建立裸鼠荷瘤模型,成瘤后随机将裸鼠分为空白组、转染对照组和siRNA-ID-1处理组,在第1、4、7、10和13 d分别注射等量的生理盐水、control-siRNA和甲基化的siRNA-ID-1。每周测量肿瘤体积,绘制肿瘤生长曲线。于第28 d处死裸鼠,取肿瘤组织行常规HE染色。结果:siRNA-ID-1处理组裸鼠肿瘤体积较空白组和转染对照组的体积小(P Objective: To investigate the inhibition effects of RNA interference targeting ID-1(si-RNA-ID-1) on the growth of Hepatocellular Carcinoma(HCC) in nude mice and the potential mechanism of ID-1 inthe development of HCC. Methods: HCC xenografts were developed by injecting HepG2 cells into BALB/C-nu nude mice. The tumor- bearing mice were randomly divided into 3 groups, including blank control group, control-siRNA group and siRNA-ID- 1 group. Each group was treated by isovolumetric normal saline, control-siRNA or siRNA-ID-1 on day 1, 4, 7, 10 and 13, respectively. The growth curves of HCC xenografts were made by the tumor sizes, which were measured per week. The nude mice were executed on day 28. The tumor tissue was prepared for the HE staining. Results: The tumor sizes in siRNA-ID-1 group were significantly smaller than that in control groups (P The results implied that ID-1 might be a potential target for the therapeutic strategy of HCC.
