YAP1 and breast cancer: It has been documented that the YAP/TAZ–TEAD pathway is critical for cancer cell motility and metastasis in many types of cancers including breast cancer (Lamar et al, 2012; Warren et al, 2018; Zanconato et al, 2016b), however, the specific YAP/TAZ targets involved in cancer cell motility are not well-established.
