Relapsed tumors retain KRAS* pathway suppression (Figure 5J) and a subset harbor genomic amplification of the Hippo pathway transcriptional coactivator, YAP1 (Kapoor et al., 2014), which we have confirmed in 3 of 7 ‘Escaper’ tumor cells lines (Figure 5J; cell lines denoted as EY1-3). The gene discussed is YAP1; the disease is neoplasm.
