摘要: 目的: 探讨蛇葡萄素钠(AMP-Na)单用及其与卡铂(CBP)合用对SPC-A-1人肺腺癌细胞增殖的抑制作用及可能的机制。方法: 采用MTT比色法测定AMP-Na单用及其与CBP合用对SPC-A-1细胞的体外细胞毒活性;用流式细胞仪分析AMP-Na单用及与卡铂合用后对SPC-A-1细胞凋亡的影响。结果: 体外细胞毒实验和流式细胞仪结果表明,AMP-Na 对人肺腺癌SPC-A-1细胞增殖的抑制作用具有明显的量效关系,与CBP联用后凋亡率较卡铂单用明显上升,有协同抑制作用。结论: AMP-Na单用能够显著抑制人肺腺癌SPC-A-1细胞的增殖,与卡铂合用可以增强卡铂的活性,协同抑制SPC-A-1细胞的增殖;AMP-Na可能是通过诱导凋亡而发挥其抗肿瘤作用。

Abstract: AIM: To investigate the cytotoxic effect and mechanism of ampelopsin sodium (AMP-Na) on human lung adenocarcionma cell line SPC-A-1 by alone or combined with carboplatin.METHODS: The inhibitory effects on proliferation of human lung cancer cell line SPC-A-1 were examined by MTT colorimetric assay. Flow cytometry (FCM) was employed to analyze the cell apoptosis.RESULTS: Experimental study on cytotoxicity in vitro showed that AMP-Na decreased the survival rate of SPC-A-1 cells in a concentration-dependent manner. There was a synergistic cytotoxic effect on SPC-A-1 cells treated with AMP-Na combined with carboplatin. The apoptosis rate in group treated with AMP-Na combined with carboplatin was significantly increased as compared with that in group treated with carboplatin alone.CONCLUSION: AMP-Na decreases SPC-A-1 cells survival rate in a concentration dependent manner, and shows significant cytotoxic activity. There is a synergistic cytotoxic effect on SPC-A-1 cells treated with AMP-Na combined with carboplatin. The mechanism of AMP-Na is probably that it can induce SPC-A-1 cells apoptosis.
