Abstract:
[摘 要] 目的:探讨1,25-二羟维生素D3 [1,25(OH)2D3]对食管鳞状细胞癌(esophageal squamous cell carcinoma,ESCC)细胞增殖、迁移和细胞周期的影响及其相关机制。方法:用不同浓度1,25(OH)2D3处理ESCC细胞TE-11、KYSE30、TE-1和KYSE510后,用CCK-8法检测细胞的增殖能力。再用浓度分别是0、0.1、0.15、0.2 μmol/L的1,25(OH)2D3处理TE-11和KYSE30细胞,划痕愈合实验、流式细胞术分别检测细胞的迁移能力和细胞周期分布情况,WB法检测细胞中cyclin D1、P27、ERK和p-ERK蛋白的表达水平。结果:1,25(OH)2D3显著抑制TE-11和KYSE30细胞的增殖能力,其抑制程度呈时间依赖性和浓度依赖性。0.1和0.2 μmol/L的1,25(OH)2D3处理48 h后,与空白对照组比较,TE-11和KYSE30细胞的迁移能力均显著降低(P<0.05或P<0.01),处于G0/G1期细胞显著增加(P<0.05或P<0.01),细胞中cyclin D1和p-ERK蛋白水平显著下调、P27蛋白水平明显上调(P<0.05或P<0.01)而ERK蛋白的表达无明显变化。结论:1,25(OH)2D3显著抑制ESCC细胞的增殖和迁移能力并阻滞细胞周期进程,其可能通过调控ERK信号通路而发挥作用。
