a Heatmap revealed that the expression of FoxM1 and ADAM17 were correlated with that of EGFR in glioblastoma samples from TCGA database. b, c The effects of FoxM1 on EGFR/AKT/GSK3β signaling pathway in glioma cells were investigated by western blot. d The key components of EGFR/AKT/GSK3β signaling were detected after knocking down FoxM1 and overexpressing ADAM17 by western blot in U251MG and U87MG cells. e The effects of FoxM1 upregulation and ADAM17 knockdown on EGFR/AKT/GSK3β signaling pathway were confirmed by western blot in SW1783 and LN229 cells. f U87MG cells were treated with TAPI-2(ADAM17 inhibitor), and then indicated proteins were measured by western blot. g After transfected with sh-ADAM17, U87MG cells were treated with CHX (0, 2, 4, 6 h) and then western blot was used to determine the expression of FoxM1. h FoxM1 levels were measured in MEF GSK3β+/+ and GSK3β−/− cells with CHX (0, 2, 4, 6 h) . i The effects of ADAM17 downregulation on FoxM1 expression in MEF GSK3β+/+ and GSK3β−/− cells. j The levels of indicated proteins were detected by western blot in U87MG-sh-ADAM17 cells treated with CHX and LiCl (0, 2, 4, 6 h)
