Project description:To assess the effects of quantitative TWIST1 dosage changes on chromatin accessibility in hESC-derived cranial neural crest cells, we performed genome editing of the H9 hESC lines to tag TWIST1 with FKBPV36 and V5, Upon differentiating edited hESC to cranial neural crest cells using an established protocol, addition of differing concentrations of the degrader molecule dTAGV-1 results in different TWIST1 concentrations, as measured by V5 intracellular staining and flow cytometry. We then profiled chromatin accessibility in each of these TWIST1 concentrations

Project description:To assess the effects of quantitative SOX9 dosage changes on gene expression in hESC-derived cranial neural crest cells, we performed genome editing of the H9 hESC lines to tag SOX9 with FKBPV36, V5, and mNeonGreen. Upon differentiating edited hESC to cranial neural crest cells using an established protocol, addition of differing concentrations of the degrader molecule dTAGV-1 results in different SOX9 concentrations, as measured by flow cytometry. We then profiled gene expression profiling in each of these SOX9 concentrations

Project description:To assess the effects of SOX9 depletion on active chromatin marks in hESC-derived cranial neural crest cells, we performed genome editing of the H9 hESC lines to tag SOX9 with FKBPV36, V5, and mNeonGreen. Upon differentiating edited hESC to cranial neural crest cells using an established protocol, addition of the degrader molecule dTAGV-1 results in SOX9 depletion. We then profiled the active chromatin mark H3K27ac by ChIP-Seq in undepleted CNCCs or CNCCs in which SOX9 was depleted for 3h or 24h. We also titrated SOX9 to four distinct levels with dTAGV-1 and assessed SOX9 binding by V5 ChIP-seq, as well as TWIST1 and TFAP2A binding by ChIP-seq.

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. Cranial neural crest and cranial mesoderm cells were isolated by flow sorting of GFP reporter-labelled cells collected from heads of E9.5 mouse embryos. Three replicates were independently isolated and hybridized to Illumina mouse WG v 2.0 chips

Upon differentiating edited hESC to cranial neural crest cells using an established protocol, addition of the degrader molecule dTAGV-1 results in SOX9 depletion. We then profiled transcription by metabolic labeling of RNA (SLAM-Seq) in undepleted CNCCs or CNCCs in which SOX9 was depleted for 3h or 24h

Chromatin extracts were subject to chromatin immunoprecipitation with anti TWIST1 monoclonal antibody (ChIP-seq). Input chromatin, not subject to ChIP was used as the negative control. Two independent replicate experiments were performed. Purified, immunoprecipitated DNA was sequenced at Australian Genome Research facility.

For microarray analysis of CM-CKO embryos, embryo heads of four genotypes were collected at E8.5 (5-7 somites) and E9.5 (18- 20 somites): CM-CKO (Twist1flox/del; Mesp1Cre/+), CM-Het (Twist1flox/wt; Mesp1Cre/+), Het (Twist1flox/del; Mesp1+/+) and Control (Twist1flox/wt; Mesp1+/+). Sample sizes for E8.5 embryos were as follows: Control, n=4 CM-CKO, n=4; Het, n=3; CM-Hets, n=3).

RNA was extracted using the RNeasy Micro kit (Qiagen) and samples sent to the Australian Genome Research Foundation for labelling and hybridization.
