摘要: 目的: 从中国皖南尖吻蝮蛇(Agkistrodon acutus) 蛇毒中提取蛇毒金属蛋白酶x(snake venom metalloproteinases, SVMP-x) 并观察其体外抗癌活性。方法: 尖吻蝮蛇粗毒冻干粉溶解并经过离子交换和凝胶过滤后纯化后得到SVMP-x 组分,CCK-8 比色法测定该组分对体外培养的肿瘤细胞的细胞毒作用。结果: 从中国皖南尖吻蝮蛇毒中分离出一种单一组分(SVMP-x), SVMP-x 呈剂量依赖性抑制体外培养的人胃癌细胞株(SGC7901) 、结肠癌细胞株(SW480) 、神经母细胞瘤细胞株(SHSY5Y)、肝癌细胞株(HepG2) 及小鼠黑色素瘤细胞株(B16) 的增殖, 并且对SGC7901 及B16 的抑制作用强于5-氟脲嘧啶(5-FU), 对SGC7901 的抑制作用呈剂量-时间依赖关系。结论: 从尖吻蝮蛇粗毒冻干粉中成功提取出抗肿瘤组分SVMP-x, 该组分对体外培养的肿瘤细胞有明显的抑制作用。

Abstract: AIM: To purify snake venom metalloproteinase x (SVMP-x) from Agkistrodon acutus Venom and investigate its anticancer activity in vitro.METHODS: The SVMP-x was separated from Agkistrodon acutus Venom by ion exchange using DEAE-Sepharose FF and SP-Sepharose FF and further purified by gel filtration through sephadex G75 columns.Different origins of tumor cell lines were cultured with different concentrations of SVMP-x.Vehicle and 5-FU were used as negative and positive control respectively.The in vitro anticancer activity of SVMP-x was determined by CCK-8 assay.RESULTS: SVMP-x was purified from Agkistrodon acutus Venom.CCK-8 assay demonstrated that SVMP-x inhibited the proliferation of SGC7901, SW480, SH-SY5Y and B16 in a dose-dependent manner.The inhibition rates of SVMP-x to SGC7901 and B16 were significantly higher than that of 5-FU positive control.SVMP-x inhibited the proliferation of SGC7901 in a time-and dose-dependent manner.CONCLUSION: An anticancer component SVMP-x is successfully purified from Agkistrodon acutus Venom and SVMP-x inhibits the proliferation of a variety of tumor cell lines in vitro.
