miR-181b overexpression inhibits glioma growth in vivo by targeting SP1. a Representative bioluminescence images of mice bearing U87 cells transfected with miR-NC, miR-181b or miR-181b plus SP1 on the days indicated (n = 10 each group). b Bioluminescence was quantified in tumors from three groups. c Kaplan–Meier survival curve of mice from three groups. d The expression of SP1, Glut1 and PKM2 were examined by Immunohistochemical staining of sections from a glioma xenograft model in mice. Scale bar = 50 μm. e The expression of SP1 were measured by Western blot in NHA, GBM cell lines, normal brain tissues (N) and tumors (T). f The expression of SP1 were examined by Immunohistochemical staining of sections from clinical normal brain tissues (NBT) and GBM samples. Scale bar = 50 μm. g SP1 expression was analyzed using TCGA data sets. h Kaplan–Meier survival curve of GBM patients with high or low SP1 levels according to TCGA data sets
