Project description:Cardiac fibroblasts (CFs) are the primary cells tasked with depositing and remodeling collagen and significantly associated with heart failure (HF). TEAD1 has been shown to be essential for heart development and homeostasis. However, endogenous fibroblast TEAD1 in cardiac remodeling remains incompletely understood. Transcriptomic analyses revealed consistently upregulated cardiac TEAD1 expression in mice 4 weeks after transverse aortic constriction (TAC) and Ang-II infusion. Further investigation revealed that CFs were the primary cell type expressing elevated TEAD1 levels in response to pressure overload. Conditional TEAD1 knockout was achieved by crossing TEAD1-floxed mice with CFs- and myofibroblasts-specific Cre mice. Echocardiographic and histological analyses demonstrated that CFs- and myofibroblasts-specific TEAD1 deficiency and treatment with TEAD1 inhibitor, VT103, ameliorated TAC-induced cardiac remodeling. Mechanistically, RNA-seq analysis identified Wnt4 as a novel TEAD1 target. TEAD1 has been shown to promote the fibroblast-to-myofibroblast transition through the Wnt signalling pathway, and genetic Wnt4 knockdown inhibited the pro-transformation phenotype in CFs with TEAD1 overexpression. Furthermore, co-immunoprecipitation combined with mass spectrometry, chromatin immunoprecipitation, and luciferase assays demonstrated interaction between TEAD1 and BET protein BRD4, leading to the binding and activation of the Wnt4 promoter. In conclusion, TEAD1 is an essential regulator of the pro-fibrotic CFs phenotype associated with pathological cardiac remodeling via the BRD4/Wnt4 signalling pathway.

Project description:TEA domain transcription factor 1 (TEAD1), a Hippo pathway transcription factor important in cellular homeostasis and development, is increasingly implicated in cancer biology. Here, we reveal a novel role for TEAD1 in organizing nuclear condensates, independent of active transcription. Using high-resolution imaging, ChIP-seq, RNA-seq and proximity-based proteomics, we demonstrate that in patient-derived renal cell carcinoma cells, TEAD1 forms micron-sized foci by binding to the heterochromatic pericentromeric regions using its DNA-binding domain. These TEAD1 foci do not mediate transcription but instead serve as depots for excess TEAD1. This contrasts with TEAD1 organization in other genomic regions of both RCC and normal kidney cells, where TEAD1 associates with markers of active transcription. Our findings provide a mechanistic framework for TEAD1’s dual regulatory roles, offering new insights into its contribution to transcriptional dysregulation and tumor progression.

Project description:Cardiac fibroblasts (CFs) are the primary cells tasked with extracellar matrix reorganization and significantly associated with heart failure (HF). Previous studies have shown that TEAD1 deficiency deteriorated heart development and homeostasis. However, the role of TEAD1 in fibroblasts during cardiac remodeling was still undiscovered. Our study demonstrated that TEAD1 was upregulated predominently in cardiac fibroblasts in mice 4 weeks after transverse aortic constriction (TAC) and Ang-II infusion. Echocardiographic and histological analyses demonstrated that CFs- and myofibroblasts-specific TEAD1 deficiency ameliorated TAC-induced cardiac remodeling and treatment with TEAD1 inhibitor, VT103, mimiced this phenotypic effect. Mechanistically, RNA-seq analysis , ChIP-Seq analysis identified TEAD1 promotes the fibroblast-to-myofibroblast transition through the Wnt signalling pathway. In conclusion, TEAD1 is an essential regulator of the pro-fibrotic CFs phenotype associated with pathological cardiac remodeling via the BRD4/Wnt4 signalling pathway.

Project description:Human cytomegalovirus (HCMV) infects up to 80% of the world’s population and is linked to serious morbidity in immunocompromised individuals and newborns. Here, using multiple genome-scale assays and computational approaches, we show that HCMV infection leads to widespread changes in chromatin accessibility and chromatin looping, with hundreds of thousands of human genomic regions affected 48 hours after infection. Integrative analyses reveal that HCMV infection perturbs the Hippo signaling pathway by drastically diminishing TEA domain transcription factor 1 (TEAD1) activity. Chromatin immunoprecipitation experiments confirm extensive concordant loss of TEAD1 binding and H3K27ac active histone marks upon infection. TEAD transcription factors are direct effectors of the Hippo signaling pathway, and our data support a position for TEAD1 at the top of a hierarchy involving key developmental pathways with differential expression subsequent to HMCV infection. Known gene targets of TEAD1, including Cellular Communication Network Factor 1 (CCN1) and Thrombospondin 1 (THBS1), are significantly downregulated with HCMV infection, reflecting diminished TEAD1-mediated activity. HCMV infection reduces TEAD1 binding through four distinct mechanisms: closing of TEAD1-bound chromatin, reduction of Yes1 associated transcriptional regulator (YAP1) and phosphorylated YAP (pYAP1) levels, reduction of TEAD1 transcript and protein levels, and alteration of TEAD1 exon-6 usage. Collectively, these comprehensive genome-scale analyses reveal novel mechanisms induced by HCMV infection.

Project description:The vestigial like family proteins (VGLL) are thought to regulate transcription by interacting with the TEA domain transcription factors (TEAD), the primary mediators of the Hippo pathway. However, the functional regulation of VGLL proteins remains poorly characterized. Here, we explored the molecular mechanism of two VGLL2 and TEAD1 fusion proteins generated by recurrent translocations in spindle cell rhabdomyosarcoma. We demonstrated that, compared to VGLL2 and TEAD1 alone, VGLL2-NCOA2 and TEAD1-NCOA2 act as strong transcriptional activators of TEAD-mediated transcription. Although VGLL2-NCOA2 and Yes1 associated transcriptional regulator (YAP) control overlapping transcriptional programs and chromatin landscapes, the downstream transcription induced by the fusion proteins does not require YAP and WW domain containing transcription regulator 1 (TAZ). Furthermore, VGLL2-NCOA2 and TEAD1-NCOA2 fusions engage distinct epigenetic regulation by recruiting E1A binding protein p300 (p300) to drive TEAD-dependent transcription. We showed that small molecule p300 inhibition can suppress VGLL2-NCOA2 and TEAD1-NCOA2-induced oncogenic transformation both in vitro and in vivo. Overall, our data reveal a tumorigenic mechanism of VGLL and TEAD fusion proteins that is related to the Hippo pathway but independent of YAP/TAZ, suggesting potential therapeutic strategies for tumors carrying VGLL, TEAD, or nuclear receptor coactivator (NCOA) gene rearrangements.
