Project description:Estrogen and estrogen receptor alpha (ERα) signaling plays an essential role in ERα-positive breast cancer. ERα mainly occupies on distal enhancers within genome and requires the cooperation of additional co-factors to tune the enhancer activity. Through in vivo proximity-dependent labeling technique BioID, we identified YAP1 and TEAD4 protein as novel co-regulators of ERα. YAP and TEAD are nuclear effectors of the Hippo pathway regulating cell proliferation, organ size and tumorigenesis. Their non-canonical function as transcriptional co-regulators for other signals have been reported but remains under investigated. Our ChIP-seq data in both MCF7 and T47D breast cancer cell lines indicated that YAP1 and TEAD4 co-bind to the strongest estrogen-responsive ERα-bound enhancers, and their bindings are augmented upon E2 stimulation. Knockdown of YAP1 or TEAD4 showed a global effect on the induction of E2/ERα target genes as examined by RNA-seq, also on E2-induced oncogenic growth of ER-positive breast cancer cells. We used Global Run-on sequencing (GRO-seq) assays to test the expression of enhancer non-coding RNAs (eRNAs), which are sensitive markers for estrogen-induced enhancer activation. Our results supported our hypothesis that the recruitment YAP/TEAD to ERα-bound enhancers is required for enhancer activation. Further studies revealed that the binding of YAP1 on ERα enhancers is a prerequisite for the recruitment of the enhancer activation machinery component MED1. These findings indicate that ERα collaborates with YAP1 and TEAD4 to activate or maintain its enhancer activity. Our data reveals a non-canonical function of YAP1 and TEAD4, which is independent of their canonical target genes, in regulating cancer growth, highlighting the potential of YAP1 and TEAD4 as actionable drug targets for ERα-positive breast cancer.

Project description:YAP is the principle effector of the Hippo signaling pathway; a key regulator of tissue homeostasis whose dysregulation is linked to cancer development. YAP regulation of gene expression is thought to involve the TEAD transcription factor family. Here we show that YAP and TEAD1 binding always co-occurs and is mediated by single as well as double TEAD1 motifs with a particular 3bp spacer (CATTCCNNNCATTCC). This suggests that YAP activity appears exclusively mediated by TEAD1. Despite being characterized as a promoter-binding factor YAP/TEAD actually binds predominantly to enhancers. Moreover we show that YAP is necessary for activity of the linked gene and proper chromatin state of regulated enhancers. These results establish mode of binding and activation of YAP mediated nuclear response of the Hippo pathway by TEAD1 and provide a comprehensive list and a novel class of direct target genes that are regulated distally and could be exploited for cancer therapeutics. Sequencing of ChIP and input samples for YAP1 and TEAD1 transcription factors and H3K27ac histone modification in SF268 glioblastoma cells and for YAP1 transcription factor in NCI-H2052 mesothelioma cells.

Project description:The genomic regulatory programs that underlie human organogenesis are poorly understood. Human pancreas development, in particular, has pivotal implications for pancreatic regeneration, cancer, and diabetes. We have now created maps of transcripts, active enhancers, and transcription factor networks in pancreatic multipotent progenitors obtained from human embryos, or derived in vitro from human embryonic stem cells. This revealed that artificial progenitors recapitulate salient transcriptional and epigenomic features of their natural counterparts. Using this resource, we show that TEAD1, a transcription factor controlled by Hippo signaling, is a core component of the combinatorial code of pancreatic progenitor enhancers. TEAD thus activates genes encoding regulators of signaling pathways and stage-specific transcription factors that are essential for normal pancreas development. Accordingly, chemical and genetic perturbations of TEAD and its coactivator YAP inhibited expression of known regulators such as FGFR2 and SOX9, and suppressed the proliferation and expansion of mouse and zebrafish pancreatic progenitors. These findings provide a resource of active enhancers and transcripts in human pancreatic multipotent progenitors, and uncover a central role of TEAD and YAP as signal-responsive regulators of the transcriptional program of early pancreas development.

Project description:The prevalent understanding of Hippo signaling is one inhibitory pathway in tumor growth via deactivating the potential of YAP-TEAD transcriptional complex. The aberrant activation of YAP was observed in a series of human malignancies. However, recent studies implicate that in certain cancer types, YAP could be a tumor suppressor. Here, we reported a context-dependent function of YAP in clear cell renal carcinoma (ccRCC). Inhibition of Hippo kinase activity impeded ccRCC tumor growth and NF-κB transcriptional programs. Pharmacological blocking Hippo kinase activity or ectopic activation of YAP suppressed tumor growth in xenograft and PDX models. Mechanism studies revealed that TEAD could synchronize with P65 for NF-κB signaling activation, while YAP disrupted TEAD-NF-κB interactions and dissociated P65 from its target gene promoter, thereby inhibiting NF-κB transcriptional programs and ccRCC tumor growth. Our study identified a novel crosstalk between Hippo and NF-κB pathway, uncovered a non-canonical regulation of Hippo/YAP axis in renal cancer and suggested a novel strategy to ccRCC treatments by YAP activation.

Project description:During placentation, placental cytotrophoblast cells differentiate into syncytiotrophoblast cells and extravillous trophoblast cells. In placenta, the expression of various genes is regulated by the Hippo pathway through the transcriptional coactivator YAP/TAZ-TEAD activity. To examine the effect of YAP/TAZ and/or TEAD on trophoblast differentiation, knockdown experiments were performed. Microarray analysis were performed to identify YAP/TAZ and/or TEAD target genes in human trophoblast.
