receptor (FGFR) oncogenic signaling pathways in cholangiocarcinoma (CCA). Yes-
associated protein (YAP) nuclear localization and up-regulation of canonical target genes
was observed in CCA cell lines and a patient-derived xenograft (PDX). Expression of
FGFR1,-2, and-4 was identified in human CCA cell lines, driven, in part, by YAP coactivation
of TBX5. In turn, FGFR signaling in a cell line with minimal basal YAP expression induced its …
