摘要: 目的: 了解中华眼镜蛇毒活性组分(CCVAF)对人非小细胞肺癌细胞株H1299 VEGF、bFGF 表达的抑制作用。方法: 采用RT-PCR 方法检测H1299细胞中VEGF、bFGF mRNA 表达的变化;利用ELISA检测培养上清中VEGF、bFGF 蛋白的含量。结果: 不同浓度的(2.0、4.0 μg·ml-1) CCVAF 对H1299 bFGFmRNA 水平有降低作用, 其中4.0 μg·ml-1 CCVAF作用7 h 后bFGF mRNA 的表达明显降低, 但对VEGF mRNA 的表达无明显影响。CCVAF 作用H1299 细胞24 h 后, 其细胞上清中VEGF、bFGF 的含量较对照组明显减少(P <0.05), 且呈剂量依赖性。结论: CCVAF 可抑制H1299 细胞bFGF mRNA 和蛋白的表达及VEGF 蛋白的表达。

Abstract: AIM: To study the effect of China cobra venom active factor (CCVAF) on the expression of VEGF and bFGF in human non-small cell lung cancer cell line H1299.METHODS: VEGF and bFGF mRNA level was measured by RT-PCR.VEGF and bFGF protein level in the supernatant was examined by ELISA.RESULTS: The mRNA expression level of bFGF was also reduced after treatment with the CCVAF in dose-dependent manner. Giving the CCVAF 4.0 μg·ml-1 to cell H1299 for 4 hours could notablely decreased the mRNA expression of bFGF while it had no such effect on VEGF mRNA expression level.The content of VEGF, and bFGF in supernatant of H1299 cells were significantly decreased after treatment for 24 hour with CCVAF in dose-dependent manner.There was significant difference compared with control group (P <0.05).CONCLUSION: CCVAF inhibits the expression of VEGF and bFGF in H1299 cells.
