Figure 4.
The effect of AXL inhibitor plus WIN55212-2 treatment on cell cycle arrest and apoptosis in HCT-8 cells. HCT-8 cells were treated with TP-0903 (30 nM or 100 nM) alone or in combination with 5 μM of WIN55212-2 for 24 h or 48 h and subjected to flow cytometry to determine cell cycle arrest (A) and apoptosis (B). (C) The percentages of the cells in G0/1, G2/M and S phases are shown in the histogram. (D) The percentages of live cells, early-stage apoptosis, late-stage apoptosis and necrotic cells are shown on the quadrants. Data are expressed as the mean ± SD from three independent experiments. ** p < 0.01 indicate a significant difference (TP-0903/WIN treat alone vs. Combination therapy).
