Figure 1. GBM cells are resistant to lapatinib but sensitive to CBL0137 and CBL0137 plus lapatinib.
Cells from xenografted GBM patient-derived tumor specimens, or a nonneoplastic brain specimen were treated with the indicated concentrations of lapatinib (Lap) and/or CBL0137 (137). Cell proliferation at the indicated time-points was normalized to the values from Day 0 [*, P<0.05; ***, P<0.001 with two-way ANOVA followed by Bonferroni’s posttest compared to Day 0; all values represent means ± SD].
