没食子酸是一种有机酸,也称为 3,4,5-三羟基苯甲酸,对某些癌细胞具有细胞毒性,而不伤害正常细胞。本研究的目的是评估没食子酸是否可以抑制神经胶质瘤细胞的活力、增殖、侵袭并减少神经胶质瘤细胞介导的血管生成。用没食子酸处理 U87 和 U251n 神经胶质瘤细胞以剂量和时间依赖性方式抑制细胞活力。 BrdU 和管形成实验表明,没食子酸分别显着降低了小鼠脑内皮细胞的胶质瘤细胞增殖和管形成。此外,没食子酸在体外可减少 U87 细胞的侵袭。 Western blot 分析显示,在 U87 和 U251n 细胞系中,没食子酸抑制了 ADAM17、p-Akt 和 p-Erk 的表达。这些数据表明,ADAM17 的抑制以及 PI3K/Akt 和 Ras/MAPK 信号通路的下调可能有助于没食子酸诱导的侵袭性降低。没食子酸可能是治疗脑肿瘤的有价值的候选者。
Gallic acid, an organic acid, also known as 3,4,5-trihydroxybenzoic acid, is cytotoxic against certain cancer cells, without harming normal cells. The objective of this study is to evaluate whether gallic acid can inhibit glioma cell viability, proliferation, invasion and reduce glioma cell mediated angiogenesis. Treatment of U87 and U251n glioma cells with gallic acid inhibited cell viability in a dose- and time-dependent manner. BrdU and tube formation assays indicated that gallic acid significantly decreased glioma cell proliferation and tube formation in mouse brain endothelial cells, respectively. In addition, gallic acid decreased U87 cell invasion in vitro. Western blot analysis showed that expression of ADAM17, p-Akt and p-Erk was suppressed by gallic acid in both U87 and U251n cell lines. These data suggest that suppression of ADAM17 and downregulation of PI3K/Akt and Ras/MAPK signaling pathways may contribute to gallic acid-induced decrease of invasiveness. Gallic acid may be a valuable candidate for treatment of brain tumor.
