HOP in gliomas and gliomaspheres. (a) Expression levels of HOP in control cortical tissues (black bars), fresh glioma samples (blue bars), culture of gliomaspheres (red bars) or U87 cells (green bars). The data are expressed as the relative ratio of HOP expression over that of GAPDH times 105. (b) Mouse HOP tagged with hemagglutinin (HOP-HA) and coupled to Penetratin was added to the medium of gliomaspheres from GBM-6 cells at 1 ÎĽM and the HA staining was developed. Cells are counterstained with Hoechst. Scale bar: 5 ÎĽm.
