摘    要:目的研究三氧化二砷(As2O3)对人肺腺癌Anip973细胞内游离[Ca2+]i的影响.方法培养人肺腺癌Anip973细胞,用激光扫描共聚焦显微镜(LSCM)观察As2O3对人肺腺癌Anip973细胞内游离[Ca2+]i的影响;用生长曲线法测药物对肿瘤细胞增殖的影响.结果①LSCM显示As2O3 作用后的人肺腺癌细胞Anip973细胞内[Ca2+]i显著升高(P<0.001).②As2O3 对人肺腺癌细胞株Anip973细胞内[Ca2+]i升高作用具有剂量依赖性.③As2O3 能明显抑制人肺腺癌Anip973细胞的增殖.结论 As2O3 可能是通过升高人肺腺癌细胞内[Ca2+]i 来启动细胞凋亡机制,诱导肺癌细胞凋亡,从而抑制其增殖.

关 键 词:三氧化二砷  细胞内游离钙  激光扫描共聚焦显微镜  生长曲线

Abstract:Objective To explore the effect of arsenic trioxide (As 2O 3) on intracellular free calcium concentration.Methods A single cell [Ca 2+ ]i was measured by laser scanning confocal microscope using Ca 2+ sensitive dye Fluo 3 /AM as a new calcium fluorescent probe; The antiproliferation activities of As 2O 3 on Anip973 cells were evaluated by means of continuous growth curve.Results As 2O 3 could obviously increase the concentration of intracellular free calcium in dose dependent manner.Conclusion The antitumor mechanism of arsenic trioxide may be that it can induce Anip973 cell apoptosis through increasing [Ca 2+ ]i level; As 2O 3 can inhibit the proliferation of Anip973 cells significantly.
Keywords:arsenic trioxide  intracellular free calcium  laser scanning confocal microscope  cell growth curve
