TWIST1 direct targets during embryonic stem cell differentiation

Project description:Twist1 encodes a basic helix-loop-helix (bHLH) transcription factor and is a key regulator of craniofacial development. Mutations of TWIST1 gene in human are associated with Saethre-Chotzen syndrome (SCS), a developmental disorder characterized by facial and skull malformations, which are phenocopied by Twist1-null heterozygous mice. Mechanisms that dictate the tissue-specificity of Twist1 in regulating distinct transcriptional targets in different craniofacial cell types remain to be determined. Our work using mass-spectrometry and co-expression analysis in cell lines and embryonic head tissues has revealed that the most prevalent forms of TWIST1 were homodimers and heterodimers with E-proteins (TCF3,TCF4 and TCF12). RNA-seq analysis of embryoid bodies expressing tethered TWIST-E-protein dimers, and ChIP-seq profiling of TWIST1 genome-wide binding sites revealed mechanisms of TWIST1 functional regulation. This study highlighted the pleiotropic roles of TWIST1 dimers in development and revealed a potential molecular mechanism underpinning Twist1-related developmental defects of craniofacial tissues.

TWIST1 direct targets during embryonic stem cell differentiation [ChIP-seq]

Project description:To understand TWIST1 function in early neural development, we analyzed genome-wide binding sites of TWIST1 in mouse embryonic stem cells (mESC) induced for neurogenic differentiation by chromatin immunoprecipitation, followed by high-throughput sequencing

Identification of TWIST1 transcriptional targets in the cranial mesoderm [E8_5]

Project description:TWIST1, a basic helix-loop-helix transcription factor is essential for the development of cranial mesoderm and cranial neural crest-derived craniofacial structures. Our previous work showed that, in the absence of TWIST1, some cells within the cranial mesoderm adopt an abnormal epithelial configuration. Here, we show by transcriptome analysis that loss of TWIST1 in the cranial mesoderm is accompanied by a reduction in the expression of genes that are associated with cell-extracellular matrix interactions and the acquisition of mesenchymal characteristics. By comparing the transcriptional profiles of cranial mesoderm-specific Twist1 loss-of-function mutant and control mouse embryos, we identified a set of genes that are both TWIST1-dependent and predominantly expressed in the mesoderm. By ChIP-seq in a cell line model of a TWIST1-dependent mesenchymal state, we identified, among the downstream genes, three direct transcriptional targets of TWIST1: Ddr2, Pcolce and Tgfbi. Our findings show that the mesenchymal properties of the cranial mesoderm is likely to be regulated by a network of TWIST1 targets genes that influence the extracellular matrix and cell-matrix interactions, and collectively they are required for the morphogenesis of the craniofacial structures.

Effect of Twist-box mutation on gene expression induced by Twist1 overexpression

Project description:Twist1 is a transcription factor that induces EMT and drives metastasis in prostate cancer. We examined global gene expression in Myc-CaP mouse prostate cancer cells following overexpression of Twist1 and the Twist1 mutants F191G, AQA, and DQD. 15 total samples were analysed, with 3 replicates of 5 groups: Twist1-WT, Twist1-AQA, Twist1-DQD, Twist1-F191G, and vector control. We performed the comparisons: WT > VEC, F191G > VEC. Samples were normalized by Twist1 expression in addition to normal
