A Novel YAP1 Inhibitor Targets CSC-Enriched Radiation-Resistant Cells and Exerts Strong Antitumor Activity in Esophageal Adenocarcinoma.

ABSTRACT: Mounting evidence suggests that the Hippo coactivator Yes-associated protein 1 (YAP1) is a major mediator of cancer stem cell (CSC) properties, tumor progression, and therapy resistance as well as often a terminal node of many oncogenic pathways. Thus, targeting YAP1 may be a novel therapeutic strategy for many types of tumors with high YAP1 expression, including esophageal adenocarcinoma. However, effective YAP1 inhibitors are currently lacking. Here, we identify a small molecule (CA3) that not only has remarkable inhibitory activity on YAP1/Tead transcriptional activity but also demonstrates strong inhibitory effects on esophageal adenocarcinoma cell growth especially on YAP1 high-expressing esophageal adenocarcinoma cells both in vitro and in vivo Remarkably, radiation-res
