摘要 目的探讨辣椒素(CAP)对人胆管癌(CCA)细胞系RBE增殖及凋亡的影响。方法体外培养的RBE细胞采用0、50、100、150、200μmol/L的CAP及200μmol/L的CAP处理0、24、48、72 h,用MTT方法和流式细胞仪检测RBE细胞增殖和凋亡能力的变化,采用Western印迹方法检测RBE细胞中磷脂酶C(PLC)-γ1信号通路的磷酸化活化情况。采用PLC-γ1信号通路抑制剂U71322阻断RBE细胞中PLC-γ1信号通路后,再以CAP处理RBE细胞,MTT方法和流式细胞仪检测RBE细胞增殖和凋亡能力的变化情况。结果与0μmol/L CAP处理组相比,50、100、150、200μmol/L的CAP可显著抑制RBE细胞的增殖能力(P<0.01),并增加RBE细胞的凋亡水平(P<0.01),且这种作用具有剂量依赖性。Western印迹结果显示,CAP显著活化RBE细胞中的PLC-γ1信号通路,且随着CAP处理浓度的升高,PLC-γ1信号通路活化水平逐渐升高。U71322阻断RBE细胞中的PLC-γ1信号通路后,CAP抑制RBE细胞的增殖能力显著降低(P<0.01)。结论通过活化PLC-γ1信号通路,CAP可抑制RBE细胞的增殖能力,并促进RBE细胞凋亡。
