These data confirmed the earlier observations that CNTB1, PDGFRB, and CBL (Fig 3B, blue circles) exhibited higher phosphorylation rates in lysates from GBM tissue, whereas EGFR and INSR (Fig 3B, green circles) exhibited higher levels of phosphorylation in lysates from the matched stem-like cell line. The gene discussed is PDGFRB; the disease is glioblastoma.
