摘要: 目的: 研究中华眼镜蛇毒组分 CⅡ(FC Ⅱ NNAV)对多药耐药KBv200 和K562/A02 细胞的抑制 作用。 方法: 应用 MTT 法观察 FC Ⅱ NNAV对 KB、 KBv200、K562 和 K562/A02 细胞的毒性作用, DNA Ladder 和流式细胞仪观察 FC Ⅱ NNAV 体外诱导 K562/A02 凋亡的作用。 结果: FC ⅡNNAV 对 KB 和 耐药KBv200 细胞以及 K562 和耐药 K562/A02 细胞 均有抑制作用, IC50 分别为 0.87 ±0.15 和 1.07 ± 0.08、0.67 ±0.11 和 0.75 ±0.01 μg·ml-1。 DNA Ladder 和流式细胞仪检测FCⅡNNAV 能明显诱导细 胞K562/A02凋亡。 结论: FCⅡNNAV 对敏感细胞 KB、K562及耐药细胞 KBv200、K562/A02 均有较强的 抑制作用,FC ⅡNNAV 能明显诱导耐药 K562/A02 细胞凋亡,这可能是其抗肿瘤多药耐药机制之一。

Abstract: AIM:To investigate the inhibition of frac-tion C Ⅱ from naja naja actra venom(FC ⅡNNAV)on multidrug-resistant tumor cell lines KBv200 and K562 A02.METHODS: Cytotoxicities of FC ⅡNNAV on KB、 KBv200、K562 and K562/A02 cells were measured by MTT assay.And the apoptosis induced by FC ⅡNNAV on K562/A02 cells were observed by DNA Ladder and flow cytometry (FCM).RESULTS: FC ⅡNNAV had the in-hibitory effects on KB 、KBv200、K562 and K562/A02 cells.The IC50 were 0.87 ±0.15、1.07 ±0.08、0.67 ± 0.11 and 0.75±0.01 μg·ml-1, respectively.It was obvi-ous that FC ⅡNNAV could induce cell apoptosis of K562 A02.CONCLUSION: FCⅡNNAV has the inhibitory ef-fect on KB、KBv200、K562 and K562/A02 cells.FC Ⅱ NNAV can induce apoptosis on multidrug-resistant tumor cell, which may be one of mechanisms for circumventing tumor multidrug-resistant.
