目的:探讨全反式维甲酸( ATRA)、5-氟尿嘧啶(5-FU)单独或联合作用对Eca109细胞增殖、迁移和血管内皮生长因子( VEGF)表达的影响。方法:将常规传代的Eca109细胞分为4组:ATRA组5、-FU组、ATRA +5-FU组和对照组,采用MTT法检测各组细胞的增殖情况,通过划痕实验测定各组细胞的迁移能力,采用RT-PCR和免疫细胞化学法分别检测各组细胞VEGF mRNA和蛋白的表达情况。结果:作用24、48和72 h后,ATRA+5-FU组的细胞生长抑制率均高于其他2组(F=234.32、13.605、73.369,P均<0.05);作用24 h后,ATRA +5-FU组的迁移率均低于其他3组(P均<0.001);作用48 h后,ATRA+5-FU组细胞VEGF mRNA和蛋白的相对表达量均低于其他3组(P均<0.05)。结论: ATRA、5-FU均能抑制食管癌细胞的增殖,且联合用药效果更为显著,可能与其抑制肿瘤血管生成有关。

Aim:To discuss effects of all-trans retinoic acid (ATRA), 5-fluorouracil (5-FU) alone or combined on proliferation, migration and VEGF expression of Eca109 cells.Methods:The cultured Eca109 cells were randomly divided into four groups:ATRA group, 5-FU group, ATRA plus 5-FU group, and control group .The cell growth inhibition rate of Eca109 cells was detected by MTT assay .Wound healing assay was used to observe the mobility rate .The mRNA and pro-tein expressions of VEGF in the cells were detected by RT-PCR and SABC method .Results: The cell growth inhibition rate of ATRA plus 5-FU group was higher than those of the other two groups at 24,48 and 72 h after treatment(F=23.432, 13.605, 73.369, P<0.05).The mobility rate of ATRA plus 5-FU group was lower than those of the other three groups at 24 h after treament(P<0.001).The relative expressions of VEGF mRNA and protein of ATRA plus 5-FU group was lower than those of the other three groups (P<0.05).Conclusion: ATRA and 5-FU could inhibit the proliferation of Eca109 cells.ATRA combined with 5-FU shows a synergistic effect on suppressing the proliferation of Eca 109 cells, which may be related to its inhibition of tumor angiogenesis .
