Project description:The tongue is a specialized muscular organ that performs multiple essential functions including mastication, deglutition, oral sensation, oral cleansing, airway maintenance and vocalization. In this study, we show Foxf1/Foxf2 serves as key mediators of hedgehog signaling in regulating myoblast migration, differentiation, and intrinsic tongue muscle organization. We took advantage of the Foxf2FLAG mice which carries 3xFLAG epitope-tagged endogenous Foxf2 protein and characterized genome-wide Foxf2 binding sites in the developing tongues using chromatin immunoprecipitation and genome sequencing (ChIP-seq). Further analyses demonstrate that Foxf1/2 transcription factors directly control the expression of Hgf, Tgfb2, and Tgfb3, to regulate tongue myogenesis.

Project description:Cleft palate is among the most common structural birth defects in humans. Previous studies have shown that mutations in FOXF2 are associated with cleft palate in humans and mice and that Foxf2 acts in a Shh-Foxf-Fgf18-Shh molecular network controlling palatal shelf growth. In this study, we generated mice carrying 3xFLAG epitope-tagged endogenous Foxf2 protein using the CRISPR/Cas9-mediated genome editing technology and characterized genome-wide Foxf2 binding sites in the developing palatal shelves using chromatin immunoprecipitation and genome sequencing (ChIP-seq). By combined analysis of ChIP-seq and RNA-seq datasets we identified a large list of Foxf2 target genes. Further analyses demonstrate that Foxf2 directly regulate expression of several genes encoding ECM or ECM modifiers during palate development. Moreover, our ChIP-seq and RNA-seq datasets provide an excellent resource for comprehensive understanding of the molecular network controlling palate development.

Project description:Cleft palate is among the most common structural birth defects in humans. Previous studies have shown that mutations in FOXF2 are associated with cleft palate in humans and mice and that Foxf2 acts in a Shh-Foxf-Fgf18-Shh molecular network controlling palatal shelf growth. In this study, we combined RNA-seq and ChIP-seq approaches to identify direct transcriptional target genes mediating Foxf2 function in palate development in mice. Of 155 genes that exhibited Foxf2-dependent expression in the developing palatal mesenchyme, 88 contained or were located next to Foxf2-binding sites. Through in situ hybridization analyses, we demonstrate that expression of many of these target genes, including multiple genes encoding transcription factors and several encoding extracellular matrix-modifying proteins, were specifically upregulated in the posterior region of palatal shelves in Foxf2-/- mouse embryos. Foxf2 occupancy at many of these putative target loci, including Fgf18, in the developing palatal tissues was verified by ChIP-polymerase chain reaction analyses. One of the Foxf2 target genes, Chst2, encodes a carbohydrate sulfotransferase integral to glycosaminoglycan sulfation. Correlating with ectopic Chst2 expression, Foxf2-/- embryos a exhibited region-specific increase in sulfated keratan sulfate and a concomitant reduction in chondroitin sulfate accumulation in the posterior palatal mesenchyme. However, expression of the core protein of versican, a major chondroitin sulfate proteoglycan important in palatal shelf morphogenesis, was increased, whereas expression of collagen I was reduced in the corresponding region of the palatal mesenchyme. These results indicate that, in addition to regulating palatal shelf growth through the Fgf18-Shh signaling network, Foxf2 controls palatal shelf morphogenesis through regulating expression of multiple transcription factors as well as through directly controlling the synthesis and processing of extracellular matrix components in the palatal mesenchyme. Our ChIP-seq and RNA-seq data sets provide an excellent resource for comprehensive understanding of the molecular network controlling palate development.

Project description:This genome-wide gene expression studies are aimed at deciphering whether FOXF2 transcriptional activity and specificity are compromised in FOXF2-expressing breast cancer cells (MDA-MB-231) compared with FOXF2-expressing normal breast epithelial cells (MCF10A).

Project description:To identify the genes and pathways regulated by FOXF2, we investigated potential FOXF2 gene targets by microarray analyses of primary prostate stromal cells (PrSC) in which FOXF2 was knocked down by siRNA. 190 differentially expressed genes were selected, of which 104 genes were more highly expressed in PrSC cells treated with FOXF2 siRNA and 86 were more highly expressed in PRSC cells treated with negative control siRNA.

Project description:Brain of the foxf2 mutant mouse embryo shows microvascular aneurysm, underdeveloped blood brain barrier and also significant defects in the tissue integrity. Foxf2 expresses in the pericytes of the brain and seem to play an important role in proper development of the BBB. Brains of E18.5 wt and foxf2 mutant mouse embryos dissected and RNA extracted from the brains using Sigma mammalian total RNA extraction kit. The RNA then been sent to th core facility for hybridization.

Project description:We performed single cell RNA-Seq of FACS-isolated CD45+ leukocytes and Lin-CD24- prostate stromal cells from Col1a2-TRAMP(Control) group and Col1a2-Foxf2-TRAMP group. Unsupervised clustering analysis on integrated single-cell datasets revealed an increased CD8+ T cell frequency and activity and a decreased Macrophage and MDSC activity in the Col1a2-Foxf2-TRAMP mice. The analysis in TRAMP mice revealed two major subpopulations that represented the myofibroblastic CAF (myCAF) and inflammatory CAF (iCAF). The percentage of myCAF increased by 15% in the Col1a2-Foxf2-TRAMP mice, suggesting that Foxf2 induced a shift toward the myCAF phenotype. On the other hand, the overall CAF gene signature score defined by the average expression of 30 CAF-associated genes on a single cell level was slightly but significantly reduced in the Col1a2-Foxf2-TRAMP mice.

Project description:Purpose: The purpose of this study is to compare the transcriptome expression profiles of E13.5 Foxf2-/-;Osr2RFP/+ and control palatal mesenchyme by using RNA-seq analysis. Methods: Foxf2+/- female mice were crossed with Foxf2+/-;Osr2RFP/+ male mice.The embryos were harvested at E13.5. The pair of palatal shelves were dissected from each Osr2-RFP+ embryo. The RFP+ palatal mesenchyme cells were isolated by using fluorescence-activated cell sorting (FACS). RNA-seq analysis was carried out using the FACS-isolated palatal mesenchyme from Foxf2-/-;Osr2RFP/+, Foxf2+/-;Osr2RFP/+ and Osr2RFP/+embryos, respectively.
