In Wnt-activated colon cancer cells, targeting of YES1 with the approved compound dasatinib inhibits tyrosine phosphorylation of YAP and activation of a β-catenin-YAP1-TBX5 transcriptional complex (Rosenbluh et al., 2012), while in mammary cells inhibition of PI3K/PDK1 was able to restrain the binding of PDK1 to SAV1, resulting disinhibition of upstream Hippo signaling, and reduction of YAP activity (Fan et al., 2013). Here, YAP1 is linked to colonic neoplasm.
