The antitumor effect of calycosin has been widely studied, but the targets of calycosin against glioblastomas are still unclear. In this study we focused on revealing c-Met as a potential target of calycosin suppressing glioblastomas. In this study, suppressed-cell proliferation and cell invasion together with induced-cell apoptosis appeared in calycosin-treated U251 and U87 cells. Under treatment of calycosin, the mRNA expression levels of Dtk, c-Met, Lyn and PYK2 were observed in U87 cells. Meanwhile a western blot assay showed that c-Met together with matrix metalloproteinases-9 (MMP9) and phosphorylation of the serine/threonine kinase AKT (p-AKT) was significantly down-regulated by calycosin. Furthermore, overexpressed c-Met in U87 enhanced the expression level of MMP9 and p-AKT and also improved cell invasion. Additionally, the expression levels of c-Met, MMP9 and p-AKT were inhibited by calycosin in c-Met overexpressed cells. However, an AKT inhibitor (LY294002) only effected on MMP9 and p-AKT, not on c-Met. These data collectively indicated that calycosin possibility targeting on c-Met and exert an anti-tumor role via MMP9 and AKT.
