AR expression in tumor tissue samples. Western blot analysis by sequential probing with an antibody against AR or GAPDH in high-grade glioma samples and normal brain (NB). The western blot figure is composed of three gels. Protein fold change (Y-axis) of each tumor sample compared with that of NB was calculated using band densitometry analysis with ImageJ software, after normalization to GAPDH (lower panel).
