芬太尼对食管鳞癌细胞株Eca109增殖及凋亡的影响

摘要

Objective:To investigate the effects of fentanyl on proliferation and apoptosis in esophageal squamous cell carcinoma cell line Eca109. Methods:Eca109 cells cultured to logarithmic phase were randomly treated with dif-ferent dose of fentanyl(0. 5,5,50,500ng/ml). MTT was applied to test the effect on cell proliferation and Annexin-V/PI assay was used to study its effect on apoptosis. Results:MTT test revealed that fentanly had no effect on prolifer-ation at 24h,but inhibited cell proliferation at 48h and 72h in a dose and time department manner. Annexin-V/PI as-say demonstrated that fentanly induced more early and late apoptosis in Eca109 cells with increased drug dose. Con-clusion:Fentanyl inhibited cell proliferation and induced apoptosis in ESCC cell line Eca109.%目的：：探讨不同浓度的芬太尼对食管鳞癌细胞株Eca109增殖和凋亡的影响。方法：选用不同浓度的芬太尼(0.5、5、50、500ng/ml)干预细胞。采用四甲基偶氮唑蓝(MMT)法检测细胞增殖,流式细胞仪Annex-in V/PI 双染色法测定细胞凋亡。结果：各组芬太尼孵育Eca109细胞24h后,对细胞的增殖无明显影响；孵育48h后,与对照组相比,各浓度组均能显著抑制细胞的增殖(P<0.05),且呈浓度和时间依赖性。芬太尼孵育Eca109细胞48h,与对照组相比,各浓度组均能诱导早期凋亡和晚期凋亡,呈浓度依赖性(P<0.05)。结论：芬太尼可抑制食管鳞癌细胞株Eca109的增殖并诱导凋亡。
