当归红芪合剂超滤膜提取物对ECV-304细胞血管内皮生长因子mRNA表达的影响

目的探讨当归红芪合剂超滤膜提取物对人脐静脉内皮细胞(ECV-304)血管内皮生长因子(VEGF)mRNA表达的影响。方法以体外培养的ECV-304细胞为模型,采用四氮唑蓝比色法(MTT法)测定细胞增殖,半定量反转录-聚合酶链反应法检测ECV-304细胞VEGFmRNA表达的变化。结果当归红芪合剂超滤膜提取物对ECV-304细胞有促增殖的作用,与对照组比较差异有统计学意义(P0.05);当归红芪合剂超滤膜提取物能够诱导VEGFmRNA的表达,其作用与剂量呈正相关。结论当归红芪合剂超滤膜提取物对ECV-304细胞的促增殖作用机制是通过诱导ECV-304细胞VEGFmRNA表达实现的。

Effects of Ultra-filtration Extract from Angelica Sinensis and Hedysarum Polybotrys's Mixture on VEGF mRNA Expression of ECV-304 Cell

Objective To study the effect of the ultra-filtration extract from Angelica sinensis and Hedysarum polybotrys’s mixture on the VEGF mRNA expression of ECV-304 cell. Method Angelica sinensis and Hedysarum polybotrys’s mixture were refined by ultra-filtration technique. ECV-304 cells were cultured as model, and its proliferation was detected by MTT colorimetry. VEGF mRNA expression was observed by semi-quantitative RT-PCR. Results The ultra-filtration extract from Angelica sinensis and Hedysarum polybotrys’s mixture could markly promote the growth of ECV-304 cells, there was significant difference between experimental and control group （P〈 0.05）. The ultra-filtration extract from Angelica sinensis and Hedysarum polybotrys’s mixture upregulated VEGF mRNA expression with dose-dependent relation. Conclusion The ultra-filtration extract from Angelica sinensis and Hedysarum polybotrys’s mixture can markly promote ECV-304 cell proliferation, which may be related to the expression of VEGF mRNA.
