| 摘 要： | 目的 探究氟尿嘧啶（5-FU）对结直肠癌RKO细胞SHP2基因表达的影响。方法 培养对数生长期的人结直肠癌细胞RKO,5-FU处理48 h后,采用免疫荧光和Western免疫印迹观察SHP2的蛋白表达水平;将能够特异性抑制SHP2表达的siRNA（siSHP2）转染RKO细胞,5-FU处理48 h,CCK8测定细胞吸光度（A）值,流式检测细胞凋亡,观察RKO对5-FU的敏感性变化及5-FU诱导细胞凋亡的影响。结果 结直肠癌细胞RKO在5-FU处理48 h后,其细胞核中SHP2的蛋白表达水平明显增高;siSHP2转染后,RKO细胞对5-FU的敏感性降低,且降低了5-FU诱导的细胞凋亡率。结论 5-FU可能通过影响SHP2的表达,促进RKO细胞的凋亡,发挥抑癌作用。

| Abstract: | Objective To investigate the effect of 5-FU on the expression of SHP2 gene in colorectal cancer cells RKO.Methods The human colorectal cancer cell line RKO of logarithmic growth phase was cultured 48 h with 5-FU. The expression of SHP2 was observed by immunofluorescence and Western blotting; siSHP2 which specifically inhibits the expression of SHP2 was transfected into RKO cells and cultured 48 h with 5-FU. The cell absorbance (A) values were measured with CCK8 and apoptosis was determined by flow cytometry. The sensitivity of RKO to 5-FU and the effect of 5-FU on apoptosis of RKO cells were observed.Results The expression of nuclear protein of SHP2 was improved remarkably after colorectal cancer cell RKO was cultured 48 h with 5-FU. The sensitivity of RKO cells to 5-FU and the cell apoptosis rate induced by 5-FU were decreased after siSHP2 transfection. Conclusion 5-FU exerts anti-cancer activity possibly due to its promoting the apoptosis of RKO cells by influencing the expression of SHP2. |
