Expression of EMT regulatory factors and signaling pathway after NF treatment in GBM cells. a After NF treatment (0–150 μM, 48 h), Slug was decreased in a dose-dependent manner. *P < 0.05, **P < 0.01 vs. control group (0 μM NF). b Immunofluorescence assay (scale bar: 200 μm) of Slug after NF treatment (30 μM, 48 h) in U87MG and U251 cells. c Western blot assay of main protein expression of signaling pathways after NF treatment (0–150 μM, 48 h). **P < 0.01 vs. control group (0 μM NF)
