TAZ, YAP/FOSL1,andYAPoverexpression in LNCaP cells at CRPC-AR and
CRPC-SCL peaks. (B) Average percentage of chromatin accessibility changes

(permutation test). (C) Overexpression ofFOSL1in LNCaP cells shows
up-regulation of CRPC-SCL signature genes. (D) Effect of verteporfin on
MSKPCa2 (CRPC-AR) and MSKPCa3 (CRPC-SCL) cell growth. (E) Effect
of T-5224 on MSKPCa2 and MSKPCa3 cell growth. (F) YAP/TAZ activity (sum
of z-scores) is significantly higher in CRPC-SCL patients. ****P <0.0001,
**P < 0.01 (one-tailed Wilcoxon rank-sum test, CRPC-SCL compared
to the other groups). (G) YAP/TAZ activity is negatively correlated with
AR expression across the 266 SU2C patients with Corr =–0.201 and
P <0.001.RESEARCH | RESEARCH ARTICLE
