- The transcriptional co-activator YAP1 oncogene is the downstream effector of the Hippo pathway, which regulates tissue homeostasis, organ size, regeneration, and tumorigenesis. Multiple cancers are dependent on sustained expression of YAP1 for cell proliferation, survival, and tumorigenesis, but the molecular basis of this oncogene dependency is not well understood. To identify genes that can functionally substitute for YAP1, we performed a genome-scale genetic rescue screen in YAP1-dependent colon cancer cells expressing an inducible YAP1-specific shRNA. We found that the transcription factor PRDM14 rescued cell proliferation and tumorigenesis upon YAP1 suppression in YAP1-dependent cells, xenografts, and colon cancer organoids. YAP1 and PRDM14 individually activated the transcription of calmodulin 2 (CALM2) and a glucose transporter SLC2A1 upon YAP1 suppression, and CALM2 or SLC2A1 expression was required for the rescue of YAP1 suppression. Together, these findings implicate PRDM14-mediated transcriptional upregulation of CALM2 and SLC2A1 as key components of oncogenic YAP1 signaling and dependency. [Display omitted] •PRDM14 substitutes for oncogenic YAP1 in YAP1-dependent colon cancers•PRDM14 activates the transcription of CALM2 and SLC2A1 to rescue YAP1 suppression•PRDM14 is essential for survival of YAP1-dependent colon cancer organoid models•PRDM14 is amplified or overexpressed in a subset of colorectal adenocarcinomas Multiple cancers are dependent on sustained expression of YAP1 for cell proliferation, survival, and tumorigenesis, but whether other genes can functionally substitute for YAP1 is not clear. Here, Kim et al. show that PRDM14-mediated transcriptional upregulation of CALM2 and SLC2A1 allow YAP1-dependent cancers to survive in the absence of YAP1.
