Since these initial studies, several others have directly implicated YAP, TAZ, or TEADs in metastasis of numerous cancer types, including melanoma [118], lung cancer [119,120,121], breast cancer [86,122,123,124,125,126,127,128], cholangiocarcinoma [82,129], gastric cancer [130,131,132,133], ovarian cancer [134], colorectal cancer [135,136,137], and oral squamous cell carcinoma [101]. This evidence concerns the gene WWTR1 and breast carcinoma.
