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

ABSTRACT: 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.

Single-cell RNA sequencing of human cervical cancer and adjacent normal tissue

Project description:Cervical cancer (CC) is the fourth leading cause of deaths in gynecological malignancies. Although the etiology of CC has been extensively investigated, the exact pathogenesis of CC remains incomplete. Recently, single-cell technologies demonstrated advantages in exploring intra-tumoral diversification among various tumor cells. However, single-cell transcriptome (scRNA-seq) analysis of CC cells and microenvironment has not been conducted. In this study, a total of 6 samples (3 CC and 3 adjacent normal tissues) were examined by scRNA-seq. Here, we performed single-cell RNA sequencing (scRNA-seq) to survey the transcriptomes of 57,669 cells derived from three CC tumors with paired normal adjacent non-tumor (NAT) samples. Single-cell transcriptomics analysis revealed extensive heterogeneity in malignant cells of human CCs, wherein epithelial subpopulation exhibited different genomic and transcriptomic signatures. We also identified cancer-associated fibroblasts (CAF) that may promote tumor progression of CC, and further distinguished inflammatory CAF (iCAF) and myofibroblastic CAF (myCAF). CD8+ T cell diversity revealed both proliferative (MKI67+) and non-cycling exhausted (PDCD1+) subpopulations at the end of the trajectory path. We used the epithelial signature genes derived from scRNA-seq to deconvolute bulk RNA-seq data of CC, identifying four different CC subtypes, namely hypoxia (S-H subtype), proliferation (S-P subtype), differentiation (S-D subtype), and immunoactive (S-I subtype) subtype. Our results lay the foundation for precision prognostic and therapeutic stratification of CC.

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.

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.

RNAseq Analysis of Transcriptome expression profiles in E13.5 Foxf2-/-Osr2RFP/+ and control palatal mesenchymal cells

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.

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

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.
