摘要: 目的:探讨5-氟尿嘧啶(5-Fu)对人结肠癌细胞凋亡及其相关基因表达的影响。方法:Hct/8细胞分为5-Fu组和对照组,通过凋亡细胞数量、形态、基因组DNA片段化及流式细胞仪检测观察5-Fu对人结肠癌细胞凋亡情况的影响,并通过基因芯片测定相关基因改变。结果:吖啶橙染色及基因组DNA电泳显示5-Fu组凋亡细胞数量明显多于对照组(P<0.01);基因芯片检测显示,5-Fu致多种基因表达发生改变,尤其是与DNA损伤修复相关基因出现表达下调。结论:5-Fu具有致人结肠癌细胞凋亡的作用,其原因是由于多种基因表达改变相互作用影响所致,尤其是DNA损伤修复相关基因的改变致不能及时修复受损的基因,最终致癌细胞发生凋亡。

Abstract: To explore the effects of 5-Fu on apoptosis of colon cancer cells (Hct/8) and related gene expressions. Methods Hct/8 were divided into 5-Fu group and control group.The apoptosis of Hct/8 treated by 5-Fu was observed using cell counting, morphology ,DNA segmentation and flow cytometry, and the changes of gene expression was analyzed by microarray chip. Results The number of apoptotic cells was greatly increased in 5-Fu group compared with control group(P<0.01),and further comfirmed by aradine staining and genomic electrophoresis. Microarray chip analysis showed that treatment of 5-Fu on Hct/8 cells resulted in changes of various gene expressions,especially down-regulated of DNA injury-repair related genes. Conclusion 5-Fu could induce the apoptosis of Hct/8 due to interaction of various gene expression changes, particularly DNA injury-repair related genes could not repair the damaged gene in time.
