c-raf-1反义寡核苷酸转染对人卵巢癌SKOV3细胞增殖的抑制作用

目的：探讨c-raf-1基因反义寡核苷酸转染对人卵巢癌SKOV，细胞增殖的抑制作用及其分子机制。方法：实验分3组：正常对照组、c-raf-1正义治疗组、c-raf-1反义治疗组。脂质体转染后不同时间分别进行MTT试验、集落形成试验、荧光显微镜检测、蛋白质荧光强度测定，以观察不同条件处理后各组细胞的增殖、凋亡、蛋白质表达有无差别。结果：反义治疗组与正义治疗组比较：转染72h OD值分别0．272与1．307（P〈0．05）；克隆形成率分别为30．6％与75．0％（P〈0．05）；凋亡率分别为19．7％与9．2％（P〈0．05），同时明显地下调P74蛋白质的表达水平（P〈0．05）。结论：c-raf-1反义寡核苷酸对人卵巢癌SKOV，细胞的增殖有明显的抑制作用。

Inhibitory effects of c-raf-1 antisense oligodeoxynucleotides transfaction on proliferation of the human ovarian carcinoma SKOV3 cell lines

Objective: To investigate the effects and the mechanisms of c-raf-1 genes antisense oligodeoxynucleotides(ASODN) transfection in inhibiting the human ovarian carcinoma SKOV3 cell lines.Methods: There were 3 groups in our study: normal control group,c-raf-1 sense oligodeoxynucleotides(SODN) experimental group,and c-raf-1 antisense experimental group.at the different time points after liposome-mediated transfection,the cell proliferation,apoptosis,protein expressing level were observed by MTT assay,flow cytometry,fluorescent microscope and cloning test.Results: In the ASODN experimental group and SODN group,the OD-value were 0.272 and 1.307 respectively(P<0.05) 72h after transfection;the cloning efficiency were 30.6% and 75.0% respectively(P<0.05);the apoptosis rate were 19.7% and 9.2% respectively(P<0.05) and the level of P74 protein was decreased statistically in c-raf-1 ASODN group.Conclusions: The proliferation of the human ovarian carcinoma SKOV3 cell lines can be inhibited by the c-raf-1 ASODN.
