摘要 目的:研究钒化钠对食管癌细胞系EC109 Caspase-3激活的影响,探讨钒化钠影响食管癌细胞系EC109细胞生长的机制。方法:以体外培养食管癌细胞系EC109为研究对象,给予0、0.1、1.0、5.0、10.0、50.0、100.0、200.0μmol/L钒化钠,培养1小时后,用Western blot技术检测食管癌细胞系EC109 Caspase-3激活情况。结果:0、0.1、1.0、5.0、10.0μmol/L钒化钠组培养1小时后,各组Caspase-3蛋白激活与对照组比较均无统计学意义;50.0、100.0、200.0μmol/L钒化钠组培养1小时后,各组Caspase-3蛋白表达均升高。结论:高浓度的钒化钠可能激活EC109细胞Caspase-3蛋白。 Objective : To study the effects of sodium orthovanadate on the activation of Caspase-3 in esophageal cancer cell line EC109. Methods: EC109 esophageal cancer cells grown in cell culture were treated with sodium orthovanadate for 1 hour at the dose of 0,0.1,1.0,5.0,10.0,50.0,100.0,200.0μmol/L respectively. Whole cell extracts were harvested and subjected to Western blotting technique to examine the activation of Caspase-3. Results: There are no statistically significant changes for the activation of Caspase -3 after sodium orthovanadate treatment at the dose of 0.1,1.0, 5.0,10.0μmol/L. However, the protein level of Caspase-3 markedly increases after sodium orthovanadate treatment at the dose of 50.0,100.0,200.0 μmol/L. Conclusion: Sodium orthovanadate at high dose may trigger the activation of caspase-3 in EC109 cells,
