WWTR1 and hepatocellular carcinoma: To further elaborate on the role of YAP and TAZ in supporting cell viability upon Sorafenib treatment of Sorafenib‐resistant HCC cells, we further employed the Promega Celltiter GloTM assay which confirmed the conclusion that YAP/TAZ promotes Sorafenib resistance via blocking ferroptosis in YAP/TAZhigh cells (Appendix Fig S1J and K).
