Gene expression profiling of the palate in Erk2 mutant mouse models

ABSTRACT: The overall goal of this project is to investigate the role of Erk2-mediated signaling in regulating the cellular metabolism of cranial neural crest (CNC) cells during palate development. Here, we conducted gene expression profiling of palate tissue from wild type mice as well as those with a neural crest specific conditional inactivation of the Erk2 gene. The latter mice exhibit micrognathia, tongue defects and cleft palate, which is among the most common congenital birth defects and observed in many syndromic conditions.

Gene expression profiling of the palate in Erk2 mutant mouse models

The latter mice exhibit micrognathia, tongue defects and cleft palate, which is among the most common congenital birth defects and observed in many syndromic conditions. To investigate the adverse effects of dysfunctional ERK signaling on the cellular metabolism of palatal mesenchyme during palatogenesis, we analyzed mice with a neural crest cell-specific conditional inactivation of Erk2 (Erk2fl/fl;Wnt1-Cre). We performed microarray analyses of primary mouse embryonic palatal mesenchymal cells of Erk2fl/fl;Wnt1-Cre mutant mice and Erk2fl/fl control mice, collected at embryonic day 13.5 (n=3 per genotype) and E14.5 (n=5 per genotype).

Gene expression profiling of primary mouse embryonic palatal mesenchymal cells in Tgfbr2 mutant mouse models

Project description:The overall goal of this project is to investigate the role of TGF-beta signaling in regulating the cellular metabolism of cranial neural crest (CNC) cells during palate development. Here, we conducted gene expression profiling of primary mouse embryonic palatal mesenchymal (MEPM) cells from wild type mice as well as those with a neural crest specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of cleft palate, which is among the most common congenital birth defects and observed in many syndromic conditions. To investigate the adverse effects of dysfunctional TGF-Beta signaling on the cellular metabolism of palatal mesenchyme during palatogenesis, we analyzed mice with a neural crest cell-specific conditional inactivation of Tgfbr2 (Tgfbr2fl/fl;Wnt1-Cre). We performed microarray analyses of primary mouse embryonic palatal mesenchymal cells of Tgfbr2fl/fl;Wnt1-Cre mutant mice and Tgfbr2fl/fl control mice, collected at embryonic day 13.5 (n=4 per genotype) and cultured with standard media (DMEM with supplements). Cells were collected after 2 passages.

Gene expression profiling of Tgfbr2 mutant mouse models of cleft palate

Project description:The overall goal of this project is to investigate the role of TGF-beta signaling in palate development in order to discover candidate therapeutics for preventing and treating congenital birth defects. Here, we conducted gene expression profiling of embryonic palatal tissue from wild type mice as well as those with a neural crest specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of cleft palate formation. To investigate the mechanism of cleft palate resulting from mutations in TGFBR2, we analyzed neural crest specific conditional inactivation of Tgfbr2 in mice (Tgfbr2fl/fl;Wnt1-Cre). We performed microarray analyses using the palatal tissue of Tgfbr2fl/fl;Wnt1-Cre mice at embryonic day E13.5 (prior to palatal fusion, n=6 per genotype) and E14.5 (during palatal fusion, n=5 per genotype) to examine the genes regulated by Tgf-beta during palate formation.

Multimodal transcriptomic profiling of the embryonic palate enables novel in utero cleft therapy [scRNA-Seq]

Project description:Cleft palate is a common disorder of development resulting from failure of growth, migration, elevation, and osteogenic fusion of embryonic cranial neural crest-derived palatal shelves. Despite progress in recent decades, the molecular pathways involved in this failure are not well understood. Here, we present a multimodal, spatiotemporal transcriptomic profiling of the developing palate through integrated, unbiased single-cell and bulk RNA-sequencing and multiplexed in situ mRNA mapping of osteogenic cell lineages. We then show that loss of Pax9, a critical transcription factor orchestrator of Wnt signaling in palate development, results in increased expression of sclerostin (Sost), a known antagonist of Wnt signaling. Finally, we reveal that a single dose of sclerostin-neutralizing monoclonal antibody restores Wnt signaling and corrects cleft palate defects in utero in Pax9-/- mouse embryos.

Tamoxifen induces cleft palate in mice

Project description:Tamoxifen (TAM), a widely-used drug in treating breast cancer, has been reported to be associated with craniofacial defects including micrognathia and cleft palate in humans. However, the exact effects of TAM on the developing palate remain unclear. In the present study, we conclude that excess TAM exposure causes cleft palate defect in mice by regulating MAPK pathways, which implicates the importance of tightly regulated MAPK signaling in palate development and provides a basis for further exploration of the molecular etiology of cleft palate defects caused by environmental factors.

Single-cell multi-omics decodes regulatory programs during development of mouse secondary palate II

Project description:Perturbations in gene regulation during palatogenesis can lead to cleft palate, which is among the most common congenital birth defects. However, currently there is no comprehensive multiomics map of the developing secondary palate. Here, we perform single-cell multiome sequencing and profile chromatin accessibility and gene expression simultaneously within the same cells (n = 36,154) isolated from mouse secondary palate across embryonic days (E) 12.5, E13.5, E14.0, and E14.5. We construct five trajectories representing continuous differentiation of cranial neural crest-derived multipotent cells into distinct lineages. By linking open chromatin signals to gene expression changes, we characterize the underlying lineage-determining transcription factors. In silico perturbation analysis identifies transcription factors SHOX2 and MEOX2 as important regulators of the development of the anterior and posterior palate, respectively. In conclusion, our study chart epigenetic and transcriptional dynamics in palatogenesis, serving as a valuable resource for further cleft palate research.
