To investigate the different effects of salvianolic acid and notoginseng triterpenes on proliferation, angiogenesis and expression of vascular endothelial growth factor in EA-hy926 cells in vitro.
EA-hy926 cells were cultured in vitro. Salvianolic acid and notoginseng triterpenes at concentrations of 0.4, 0.8 and 1.2 mg·L(-1) were used to culture EA-hy926 cells. EA-hy926 cells in a blank control group were grown in culture solution only. Viability of cells was assessed by CCK-8, and after treated for 12 h, capillary-like structures were examined. After 24 h culture, the expression of VEGF was detected by real-time PCR.
Salvianolic acid at 0.4, 0.8 mg·L(-1), the same as notoginseng triterpenes, increased VEGF content in EA-hy926 cells. Expression of VEGF protein in the salvianolic acid at 1.2 mg·L(-1) group, was up-regulated as compared with notoginseng triterpenes group (P < 0.05).
Salvianolic acid and notoginseng triterpenes can promote EA-hy926 cell proliferation, angiogenesis and expression of VEGF protein. This analysis also provided evidence that salvianolic acid had the better effects as compared with notoginseng triterpenes.
研究丹酚酸和三七总皂苷对体外 EA-hy926 细胞增殖、血管生成及血管内皮生长因子表达的影响。
体外培养 EA-hy926 细胞,分别用浓度为 0.4、0.8、1.2mg·L(-1)的丹酚酸和三七总皂苷培养 EA-hy926 细胞,空白对照组仅用培养液培养 EA-hy926 细胞。用 CCK-8 法检测细胞活力,作用 12 h 后观察毛细血管样结构,培养 24 h 后用实时 PCR 法检测 VEGF 的表达。
丹酚酸 0.4、0.8mg·L(-1)组与三七总皂苷组一样,均能增加 EA-hy926 细胞中 VEGF 的含量。1.2mg·L(-1)丹酚酸组 VEGF 蛋白表达较三七总皂苷组上调(P<0.05)。
丹酚酸和三七总皂苷均可促进 EA-hy926 细胞增殖、血管生成及 VEGF 蛋白表达,且丹酚酸的作用优于三七总皂苷。
