Netrin-1 promoted the expression of the oncogene c-Myc. (a) Immunoblotting analyses of the expression of selected oncogenes in U251 and U87MG cells after stimulation with recombinant human netrin-1. (b) Quantification of c-Myc, cyclin D1, p27, cdk2 and cyclin E expression using Gel-Pro Analyzer 4 software. (c) c-Myc expression was detected by real-time PCR in U251 and U87MG cells in the absence or presence of netrin-1. (d) Western blotting analyses of c-Myc in U251 cells that were infected with lentivirus expressing shCtrl or shNetrin-1. GAPDH was used as the loading control. (e) c-Myc expression was detected by real-time PCR in U251 cells that were infected by lentivirus expressing shCtrl or shNetrin-1. (f) Representative images of c-Myc staining in U251-derived tumor sections. Boxed areas in the top row defined regions shown at a higher magnification in the bottom row. Scale bar: 50 µm. (g) Relative expression of c-Myc in U251-derived tumors. The mean IOD of c-Myc was calculated using Image-Pro Plus.
