Project description:100 pM of recombinant TGF-β1 protein was used to stimulate the TEAD4-expressing HCCLM3 stable cells or the vector-expressing control cells for different time periods (0 / 4 / 12 h). Then cells were harvested for total RNA extraction and RNA-Seq analysis. Genes whose transcriptional responsiveness to TGF-β1 was attenuated by TEAD4 were underscored.

Project description:Collagen triple helix repeat containing 1 (CTHRC1) has been found to be up-regulated in many human solid tumors. In this study, we investigated the changes of gene expression by comparing CTHRC1-siRNA and Scramble-siRNA control in hepatocellular carcinoma cell line HCCLM3, which has high expression levels of CTHRC1. Differential gene expression was assessed by Affymetrix microarray experiments for 2 samples: CTHRC1-siRNA-treated HCCLM3 cells and Scramble-siRNA-treated HCCLM3 cells.

Project description:We established GFP/CCDC137-APOBEC1 transfected HCCLM3 cells.Then doxycycline was added to induce the expression of GFP/CCDC137-APOBEC1.We then performed gene expression profiling analysis using RNA obtained from GFP/CCDC137-APOBEC1 overexpressing HCCLM3 cells with or without doxycycline treatment.

Project description:The TEAD (1-4) transcription factors comprise the conserved TEA/ATTS DNA binding domain recognising the MCAT element in the promoters of muscle-specific genes. Despite extensive genetic analysis, the function of TEAD factors in muscle differentiation has proved elusive due to redundancy amongst the family members. Expression of the TEA/ATTS DNA binding domain that acts a dominant negative repressor of TEAD factors in C2C12 myoblasts inhibits their differentiation, while selective shRNA knockdown of TEAD4 results in abnormal differentiation characterised by the formation of shortened myotubes. Chromatin immunoprecipitation coupled to array hybridisation (ChIP-chip) shows that TEAD4 occupies 867 promoters including those of myogenic miRNAs. We show that TEAD factors cooperate with MYOD1 to directly induce Myogenin, CDKN1A and Caveolin 3 expression to promote myoblast differentiation and fusion. RNA-seq identifies a novel set of TEAD4 target genes encoding muscle structural and regulatory proteins and those required for the unfolded protein response. In contrast, TEAD4 represses expression of the growth factor CTGF and Cyclin D1 to promote differentiation. Together these results show that TEAD factor activity is essential for C2C12 cell differentiation and define a novel and nonredundant role for TEAD4 in regulating the unfolded protein response. C2C12 cells were infected with retrotiviral vector expressing Flag-HA-Tagged TEAD4 or with empty control vector and selected in the continouos presence of puromycin. Infected cell populations were then differentiated for 5 days in DMEM medium with 2% horse serum and fixed in 0.4% formaldehyde.

Project description:We have identified TEAD4 as a key prognosis factor in colorectal cancer. To elucidate the potentail mechanism and function of TEAD4 in colorectal caner, we generated two stable cell lines expressing different shRNA targeting TEAD4 in the mesenchymal-like LoVo cells and the differential genes were detected by microarray.

Project description:In the preimplantation mouse embryo TEAD4 is critical to establishing the trophectoderm (TE)-specific transcriptional program and segregating TE from the inner cell mass (ICM). However, TEAD4 is expressed both in the TE and the ICM. Thus, differential function of TEAD4 rather than expression itself regulates specification of the first two cell lineages. We used ChIP-seq to define genome-wide TEAD4 target genes and asked how transcription of TEAD4 target genes is specifically maintained in the TE. Our analyses revealed an evolutionarily conserved mechanism, in which lack of nuclear localization of TEAD4 impairs the TE-specific transcriptional program in inner blastomeres, thereby allowing their maturation towards the ICM lineage. Restoration of TEAD4 nuclear localization maintains the TE-specific transcriptional program in the inner blastomeres and prevents segregation of the TE and ICM lineages and blastocyst formation. We propose that altered subcellular localization of TEAD4 in blastomeres dictates first mammalian cell fate specification.

Project description:To access oncogenic roles of TEAD4 in gastric cancer, TEAD4-regulated genes were investigated using a SNU216 cell line in which TEAD4 expression was knockdown by shRNA. To compare control to TEAD4 knockdown cell, total RNA was extracted from two cell lines generated by non-silencing shRNA control and TEAD4 knockdown.

Project description:Analysis of primary bovine aortic endothelial cells treated for 24 hours with TGF-beta 1 5 ng/ml. TGF-beta 1 has been shown to induce endothelial-to-mesenchymal transition (EndoMT) and to be implicated in differentiation of endothelial cells into smooth muscle-like cells as occurred in vascular neointimal formation. Primary aortic endothelial cells seeded on 10 mm diameter plates were incubated with TGF-beta 1 (5 ng/ml) for 24 hours or left under basal conditions. Triplicates from three different cultures.
