AXL and esophageal adenocarcinoma: The clonogenic survival assay demonstrated enhanced sensitization to radiation by BAY1143572 in esophageal adenocarcinoma cells with stable overexpression of Axl (FLO-1 Axl and SKGT4 Axl) compared to negative control cells (FLO-1 RFP and SKGT4 RFP) OE33 at 4, 6 or 8 Gy (Figure 7B).
