Figure Lengend Snippet: In vitro evaluation of sequential dosing of SN38 and/or eltanexor in CRC cell lines (HCT8, HCT116, LS1034, and HCT15). (A) Dosing strategies for in vitro viability assay. Cells were incubated with SN38 [10 nM] for the first 24 hours. Cells were then washed with PBS and incubated with eltanexor [100 nM] for an additional 48 hours. (B) Cell viability % measured by CellTiter Glo 2.0 and (C) heatmaps of the 4 CRC cell lines treated sequentially with SN38 [0 - 30 nM] followed by eltanexor [0 -100 μM]. Bliss synergy score was analyzed using SynergyFinder.

Figure Lengend Snippet: Immunocytochemistry in HCT8 and HCT 116 cell lines. Cells were first treated with SN38 (10 nM) in time series (0 hr, 2 hr, 4 hr, and 6 hr). Cells were washed with PBS and then treated with eltanexor (1 uM) for 48 hours. Cells were fixed and then stained with p53 and p21 for cell cycle arrest or stained with P-H2A.X for double stained DNA breaks.
