摘要: 摘要: 目的 探讨去氧鬼臼毒素对人肺癌 NCI-H358 细胞增殖和体外迁移的影响, 并初步探讨其作用机制。方 法 应用 CCK-8 法、 流式细胞术、 细胞划痕实验和 DCFH-D 法分别检测去氧鬼臼毒素对 NCI-H358 细胞增殖、 周期 分布、 凋亡、 体外迁移能力和细胞内活性氧(ROS)的影响, 并通过 Western blot 检测去氧鬼臼毒素对细胞周期蛋白 (Cyclin) B1、 细胞分裂周期蛋白 25 同源蛋白 (Cdc25c)、 细胞周期蛋白依赖性激酶 (CDK) 1、 半胱氨酸天冬氨酸蛋白酶 (Caspase) -3、 p53 肿瘤蛋白、 B 淋巴细胞瘤 (Bcl) -2 和基质金属蛋白酶 (MMP) 9 的表达水平, 以及细胞外信号调节激 酶(ERK) 1/2、 p38 分裂原激活蛋白激酶(MAPK)和 c-Jun 氨基末端激酶(JNK)的磷酸化水平的影响。结果 去氧鬼 臼毒素能明显抑制肺癌 NCI-H358 细胞的生长, 流式细胞结果显示其能诱导细胞停滞在 G2/M 和 S 期, 诱导细胞凋 亡和细胞 ROS 产生, 同时细胞体外迁移能力也明显下调。Western blot 结果显示, 去氧鬼臼毒素能使 Cyclin B1、 Cdc25c、 CDK1、 Bcl-2 和 MMP9 的蛋白表达明显下调, 而 Caspase-3 和 p53 的表达明显上调, 且 ERK1/2、 p38MAPK 和 JNK 的磷酸化水平明显受到抑制。结论 去氧鬼臼毒素可抑制肺癌 NCI-H358 细胞的增殖和体外迁移, 是一种潜在 的抗肿瘤药物

Abstract: Abstract: Objective To investigate the effects and mechanism of deoxypodophyllotoxin on cell proliferation and mi⁃ gration of human lung cancer NCI-H358 cells in vitro. Methods CCK-8 assay, flow cytometry assay, wound healing assay and DCFH-DA assay were used to detect the effects of deoxypodophyllotoxin on the proliferation, cells cycle, apoptosis, mi⁃ gration and reactive oxygen species (ROS). The protein expressions of Cyclin B1, Cdc25c, CDK1, Caspase-3, p53, Bcl-2, MMP9, ERK1/2, p38MAPK and JNK were measured by Western blot assay, respectively. Results Deoxypodophyllotoxin inhibited cell proliferation and reduced migration in human lung cancer NCI-H358 cells. Flow cytometry analysis showed that treatment with deoxypodophyllotoxin resulted in cell cycle G2/M and S phase arrest, cell apoptosis and ROS production. The result of Western blot assay showed that protein expressions of Cyclin B1, Cdc25c, CDK1, Bcl-2 and MMP9 were down regulated while Caspase-3 and p53 were up-regulated. Moreover, Deoxypodophyllotoxin treatment decreased the phosphory⁃ lated levels of ERK1/2, p38MAPK and JNK obviously. Conclusion Deoxypodophyllotoxin could suppress the proliferation and migration of human lung cancer NCI-H358 cells in vitro, which is a potential anti-tumor drug.
