摘 要:目的:分析探讨塔斯品碱衍生物对人肝癌SMMC7721细胞的生长抑制作用,研究其作用机制。方法:采用MTT法测定5种塔斯品碱衍生物对肝癌SMMC7721细胞生长的抑制作用,流式细胞术检测Tas-D1对肝癌SMMC7721细胞周期的影响,ELISA法测定Tas-D1对肝癌SMMC7721细胞EGF和VEGF蛋白的影响,PCR法测定Tas-D1对EGF和VEGF的mRNA水平的影响。结果:塔斯品碱衍生物Tas-D1对SMMC7721细胞生长具有明显的抑制作用,使细胞阻滞在S期,呈现出良好的剂量依赖性。ELISA法和RT-PCR法结果表明Tas-D1对SMMC7721细胞的EGF和VEGF蛋白质的表达和mRNA的表达有一定的抑制作用(P<0.05)。结论:塔斯品碱衍生物Tas-D1能抑制人肝癌SMMC7721细胞的生长,转换细胞周期,初步作用机制主要为Tas-D1抑制SMMC7721细胞EGF和VEGF的表达。Objective:To analyse the inhibition effect of taspine derivatives on human Liver cancer SMMC7721 cell and its mechanism.Methods:The effects of five taspine derivatives on SMMC7721 cell growth were determined by MTT.The flow cytometry was used to determine the cell cycle.The effects of Tas-D1 on the EGF and VEGF in SMMC7721 cell were determined by ELISA.The mRNA level of EGF and VEGF in SMMC7721 cell was determined by RT-PCR.Results:The MTT assay demonstrated that the taspine derivative Tas-D1 significantly inhibited the growth of SMMC7721 cell in a dose-dependent manner.Cell was stopped at S phase by Tas-D1.Tas-D1 inhibited the expression of EGF and VEGF and their mRNA in a dose-dependent manner(P0.05).Conclusions:The taspine derivative Tas-D1 can inhibit the growth of human Liver cancer SMMC7721 cell and change cell cycle,which may be related to the inhibition of EGF and VEGF expression.
