TEAD4 and triple-negative breast carcinoma: As the most activated YAP/TAZ/TEAD4-bound chromatin regions are located within enhancers [29], we used an in silico approach to interrogate enhancers in chromatin immunoprecipitation sequencing (ChIPseq) data of YAP, TEAD4, and TAZ in MDA-MB-231, a triple-negative breast cancer cell line with known high YAP activity [29].
