KCNA1 is upregulated at the Leading Edge A–B the heatmap (A) and histogram (B) of KCNA1–KCNA6 mRNA expression in the Ivy Glioblastoma Atlas Project (C) immunohistochemical staining of GBM tissue in the tumor core and leading edge (the middle and rest scale bar are 500 μm and 100 μm, respectively). D Western blot to detect KCNA1 expression in different cell lines. Data are expressed as standard deviation. E Immunofluorescence assay of KCNA1 and TOMM20 in different cell lines (the scale bar is 50 μm)
