Project description:Regulation of organ size is important for development and tissue homeostasis. In Drosophila, Hippo signaling controls organ size by regulating the activity of a TEAD transcription factor, Scalloped, through modulation of its coactivator protein Yki. The role of mammalian Tead proteins in growth regulation, however, remains unknown. Here we examined the role of mouse Tead proteins in growth regulation. In NIH3T3 cells, cell density and Hippo signaling regulated the activity of Tead proteins by modulating nuclear localization of a Yki homologue, Yap, and the resulting change in Tead activity altered cell proliferation. Tead2-VP16 mimicked Yap overexpression, including increased cell proliferation, reduced cell death, promotion of EMT, lack of cell contact inhibition, and promotion of tumor formation. Growth promoting activities of various Yap mutants correlated with their Tead-coactivator activities. Tead2-VP16 and Yap regulated largely overlapping sets of genes. However, only a few of the Tead/Yapregulated genes in NIH3T3 cells were affected in Tead1-/-;Tead2-/- or Yap-/- embryos. Most of the previously identified Yap-regulated genes were not affected in NIH3T3 cells or mutant mice. In embryos, levels of nuclear Yap and Tead1 varied depending on cell types. Strong nuclear accumulation of Yap and Tead1 were seen in myocardium, correlating with requirements of Tead1 for proliferation. However, their distribution did not always correlate with proliferation. Taken together, mammalian Tead proteins regulate cell proliferation and contact inhibition as a transcriptional mediator of Hippo signaling, but the mechanisms by which Tead/Yap regulate cell proliferation differ depending on cell types, and Tead, Yap and Hippo signaling may play multiple roles in mouse embryos. We used microarrays to know the gene expression profiles regurated by Tead2-VP16, Tead2-EnR, Yap, and cell density in NIH3T3 cells. Keywords: Cell density, genetic modification Tead2-VP16-, Tead2-EnR-, Yap- and control vector-expressing cells were cultured at low or high density for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Cellular changes during an epithelial-mesenchymal transition (EMT) largely rely on global changes in gene expression orchestrated by transcription factors. Tead transcription factors and their co-factors Yap and Taz have been shown to be implicated in EMT, nevertheless, their direct target genes during EMT have remained elusive.We used genome-wide chromatin immunoprecipitation and next generation sequencing to identify diect Tead2 target genes during EMT. Py2T cells (murine breast cancer cell line) were treated with TGFβ for 5 days and subjected to ChIP using an antibody for Tead2 followed by next generation sequencing (Illumina HiSeq 2000; n=2)

Project description:We investigate the dependence of human malignant pleural mesothelioma on a functional YAP1-TEAD transcription factor complex to maintain fully established tumors in vivo. We show that, in a dysfunctional Hippo genetic background, expression of a dominant negative TEAD2 modulates YAP1/TEAD-dependent gene expression and inhibits growth of established tumor xenografts. Our data demonstrate that, in the context of a mutated Hippo pathway, TEAD2 activity is essential to maintain the growth of mesothelioma tumors in vivo, thus validating the concept of inhibiting the activated YAP1/TEAD complex for the treatment of malignant pleural mesothelioma patients.

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.

Project description:Angiogenesis, the process by which endothelial cells (ECs) form new blood vessels from existing ones, is intimately linked to the tissue's metabolic milieu and often occurs at nutrient-deficient sites. However, ECs rely on sufficient metabolic resources to support growth and proliferation. How endothelial nutrient acquisition and usage are regulated is unknown. Here we show that these processes are dictated by YAP/TAZ-TEAD – a transcriptional module whose function is highly responsive to changes in the tissue environment. ECs lacking YAP/TAZ or their transcriptional partners, TEAD1, 2, and 4 fail to divide, resulting in stunted vascular growth in mice. Conversely, activation of TAZ, the more abundant paralogue in ECs, boosts proliferation, leading to vascular hyperplasia. We find that YAP/TAZ promote angiogenesis by fueling nutrient mTORC1 signaling. By orchestrating the transcription of a repertoire of cell-surface transporters, YAP/TAZ-TEAD stimulate the import of amino acids and other essential nutrients, thereby enabling mTORC1 pathway activation. Dissociating mTORC1 from these nutrient inputs – elicited by the loss of Rag GTPases – inhibits mTORC1 activity and prevents YAP/TAZ-dependent vascular growth. These findings define a pivotal role for YAP/TAZ-TEAD in steering endothelial mTORC1 and illustrate the essentiality of coordinated nutrient fluxes in the vasculature.

Project description:YAP1 (Yes-associated protein 1) is transcriptional co-activator that partners with the TEAD family of transcription factors to regulate gene expression. Increased YAP-TEAD activity is strongly implicated in the development, progression, and metastasis of several cancer types including melanoma, but the YAP-TEAD target genes that are responsible for YAP-TEAD-dependent melanoma progression and metastasis are largely unknown. To identify YAP-TEAD regulated genes in metastatic melanoma cells we used RNA-sequencing to compare gene expression in control A375 human melanoma cells to A375 cells expressing mutant forms of YAP with increased transcriptional activity due to the mutation of LATS inhibitory phosphorylation sites (YAPS127A or YAPS127A,S381A). To determine which YAP-dependent gene expression changes are mediated by TEADs we also included a mutant form of YAP that is unable to bind TEADS (YAPS94A,S127A).

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.
