Figure 4From: Molecular mechanism of the schedule-dependent synergistic interaction in EGFR-mutant non-small cell lung cancer cell lines treated with paclitaxel and gefitinibEffect of paclitaxel on EGFR phosphorylation. PC-9 and H1650 cells were exposed to 1, 2 and 3 fold IC50 dose paclitaxel for 24 h. A dose-dependent increase in EGFR phosphorylation levels were observed.Back to article page
