Genome-wide identification of Foxf2 transcriptional target genes in tongue development

ABSTRACT: 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.

Genome-wide analysis of gene expression changes in mouse tongue squamous cell carcinomas induced by 4-nitroquinoline 1-oxide (4-NQO)

Project description:We hypothesized that the expression of many genes are dysregulated during oral cancer carcinogenesis. We examined genome-wide transcript levels in normal mouse tongues and the tongue squamous cell carcinomas induced by 4-NQO. The results will provide important information for the diagnosis, prevention, and treatment of human oral cancers, including tongue cancer. Total RNA obtained from normal tongues (not treated with 4-NQO) and tongue squamous cell carcinomas induced by 4-NQO.

siRNA profiling of human primary prostate stromal cells knocked down for FOXF2

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. Experiment Overall Design: In each experiment, we compared gene expression of PrSC cells treated with FOXF2 siRNA versus PrSC cells treated with negative control siRNA, in a total of 6 affymetrix arrays. 190 differentially expressed genes were selected (ratio negative control siRNA/siRNA â¥ 2log |0.8| as average in all arrays).

RNA Microarray data from embryonic mouse brains wt vs foxf2 mutant

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.

Differential expression of microRNAs between oral squamous cell carcinoma and healthy control tongues

Project description:In order to identify aberrantly expressed microRNAs in oral squamous cell carcinomas (OSCCs), we have employed microRNA microarray profile using healthy tongue samples as control. All seventeen human OSCCs and three normal tongue tissues were collected from the Tissue Bank at the Moffitt Cancer Center and approved by the University of Florida institutional review board. Majority (15 out of 17) of the OSCCs were derived from tongue cancers. The tumor samples contained greater than 80% of cancerous cells, confirmed by microscopic examination by a head and neck pathologist. The normal tongues were taken from a non-cancerous region. Tissues were snap-frozen and stored at -80M-BM-0C until further use. Total RNAs were isolated from human tissues using mirVana miRNA Isolation kit (Ambion/Applied Biosystems, Austin, TX) according to the manufacturerM-bM-^@M-^Ys instruction. NanoDropM-BM-. ND-100 spectrophotometer (Thermo Scientific, Wilmington, DE) was used to quantify the isolated RNA. The Agilent 2100 Bioanalyzer from the Interdisciplinary Center for Biotechnology Research at the University of Florida was used to detect the size distribution of total RNA and to determine the quality as well. Expression of microRNAs from this signature was quantified in the same RNA samples by real-time PCR, confirming the expression pattern. Human tissues of oral squamous cell carcinoma and healthy normal tongues were used for microRNA microarray profile to identify aberrantly expressed microRNAs in oral squamous cell carcinomas.

Genome-wide identification of Foxf2 transcriptional target genes in 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 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.

Stromal FOXF2 suppresses prostate cancer progression and metastasis by enhancing antitumor immunity

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.
