Recent identification of intestinal epithelial stem cell (ISC) markers and development of ISC reporter mice permit visualization and isolation of regenerating ISCs after radiation to define their functional and molecular phenotypes. Previous studies in uninjured intestine of Sox9-EGFP reporter mice demonstrate that ISCs express low levels of Sox9-EGFP (Sox9-EGFP Low), whereas enteroendocrine cells (EEC) express high levels of Sox9-EGFP (Sox9-EGFP High). We hypothesized that Sox9-EGFP Low ISCs wo ...[more]

Characterization of IGF1 effects on the transcriptome of normal and irradiated Sox9-EGFP cell populations

Project description:Transcriptional profiling of intestinal epithelial cells expressing either Negative, Sublow, Low or High levels of the Sox9-EGFP reporter transgene FACS-isolated from jejunum of non-irradiated mice or at 5 days after 14Gy abdominal irradiation. In both groups, mice were treated for 5 consecutive days with either IGF1 or vehicle via mini-pumps (Alzet 1007D, IGF1 at 10mg/ml) implanted subcutaneously immediately following radiation. 4 distinct cell populations FACS-isolated based on levels of expression of the Sox9-EGFP reporter transgene (Sox9-EGFP Negative, Sublow, Low and High cells). 4 conditions: Non-irradiated/vehicle vs Non-irradiated/IGF1 vs Irradiated/vehicle vs Irradiated/IGF1. Biological replicates: 7 independent non-irradiated mice treated with vehicle - 3 independent non-irradiated mice treated for 5 days with IGF1 - 3 independent irradiated mice studied at day 5 post-irradiation treated with vehicle - 3 independent irradiated mice studied at day 5 post-irradiation treated for 5 days with IGF1.

Digit patterning is controlled by a Bmp-Sox9-Wnt Turing network modulated by morphogen gradients

Project description:The goal of this microarray analysis was to see which genes are differentially expressed between Sox9-EGFP positive cells and Sox9-EGFP negative cells in E11.5 mouse limb bud autopods of the reporter Sox9-EGFP knock-in mouse(Nakamura et al 2011). This was done in order to gain insight of the genes that could contribute to the specification of the digits (Sox9 positive cells). Mesenchymal cells were extracted from the mouse (Sox9EGFP knock-in, Nakamura et al . 2011) embryo forelimb autopod at stage E11.5. Sox9EGFP-positive cells were FACS-sorted from Sox9EGFP-negative cells . Each FACS-sorted sample was made from several forelimb autopods (approximately n=10). Three replicates were used for each group of Sox9EGFP-positive cells and Sox9EGFP-negative cells. Extraction of total RNA, labeling and hybridization to the microarray were performed using attached protocols. We identified the genes that were differentially expressed between the two groups.

Expression data of Sox9+ and Ngn3+ mouse pancreas cells at different stages of development

Project description:Genes specific to Sox9+ pancreatic progenitors were identified by comparing the gene expression in embryonic and adult Sox9+ cells. We used microarray analysis to detail the global changes in gene expression as Sox9 positive embryonic pancreatic progenitors differentiatiate into adult ductal cells or the endocrine lineage. GFP positive cells from Sox9-EGFP mouse pancreas were isolated by FACS at different stages of development (e10.5, e15.5, and p23) for RNA extraction and hybridization to Affymetrix microarrays. To obtain populations highly enriched in Sox9 expression, we collected only GFP Hi populations for analysis. To identify gene expression changes specific to the differentiation of progenitors to ductal cells or endocrine cells, we also isolated and analyzed the gene expression profile of GFP negative cells isolated at p23, as well as GFP positive cells isolated from Ngn3-EGFP mouse pancreas at e15.5. These two populations allow the identification of genes whose expression is associated with the newly differentiated endocrine progeny in the embryo (Ngn3-GFP positive) and adult acinar and endocrine cells at p23.

Distinct regulatory programs for Sox9 in transcriptional regulation of the developing mammalian chondrocyte [RNA-seq]

Project description:We compared Sox9-association at chondrocyte targets to a broad catalogue of regulatory indicators of chromatin organization and transcriptional activity to determine Sox9’s direct regulatory actions in normal developing chondrocytes. Sox9-associated regions resolve into two distinct regulatory categories. Class I regions closely associate with transcriptional start sites (TSSs). Their targets reflect general regulators of basal cell activities that Sox9 engages indirectly through a likely association with the basal transcriptional complex. In contrast, Class II regions outside of the local TSS domains highlight evolutionarily conserved, active enhancers directing expression of chondrocyte specific target genes, though DNA binding of Sox9-dimers at target sites with sub-optimal binding affinity. The level of associated chondrocyte gene expression correlates with the number of enhancer modules around the target gene and grouping into super-enhancer clusters. Comparison of Sox9 programs between neural crest and mesoderm-derived chondrocytes points to similar modes of chondrocyte specification in distinct chondrocyte lineages. These data provide the first insight into mammalian Sox family actions at the genome scale in the vivo setting. The resulting enhancer sets provide a key resource for further dissection of the regulatory programs of mammalian chondrogenesis. Incorportation of ChIP-seq data of Sox9 and histone modification marks for chromatin status together with micorarray gene expression profiling in neonatal mice chondrocytes to uncover Sox9 regulatory system.

Whole genome expression analysis of tumor regulatory T cells expressing interleukin-10

Project description:The tumor microenvironment contains high frequencies of inflammatory regulatory T (Treg) cells. These Treg exhibit superior regulatory function compared with those from other environments such as the spleen, partially due to expression of anti-inflammatory interleukin-10. In order to gain insight into the origins and functional roles of different Treg subsets, we used whole genome microarray analysis to characterize tumor IL-10+ and tumor IL-10- Treg subsets obtained from VERT-X reporter mice bearing transplantable tumors, along with total tumor Treg and spleen Treg from FoxP3-EGFP reporter mice. Few genes were found to differ between IL-10+ and IL-10- tumor Treg subsets (29 upregulated, 88 downregulated), suggesting a common origin of each Treg subset. The specific gene expression profile of IL-10+ tumor Treg was associated with the tumor microenvironment and absent from spleen Treg, suggesting it to be driven by components of the inflammatory tumor microenvironment. The IL-10+ tumor Treg gene expression profile displayed upregulation of genes associated with a higher activation state and greater effector function. Pooled MC38 tumor tissue from VERT-X or FoxP3-EGFP reporter mice were used to obtain IL10+ tumor Treg (VERT-X), IL10- tumor Treg (VERT-X) and total tumor Treg (FoxP3-EGFP). Spleens from tumor-free FoxP3-EGFP mice were used for spleen Treg. Three experiments for each population gave a total 12 RNA samples.

Expression data from E10.5 mouse otocyst

Project description:We established a novel EGFP reporter mouse line (named Tg(ETAR-EGFP)14Imeg), which enables the placode-derived inner ear sensory cell lineage to be visualized and monitored. At E10.5, EGFP expression was detected in the ventral and dorsomedial region of the otocyst. Using this reporter line and FACS-array technology, we performed gene expression profiling focused on the regional specificity of the otocyst. We sorted E10.5 otocyst epithelial cells of heterozygous mice into EGFP-positive and EGFP-negative cells for RNA extraction and hybridization on Affymetrix microarrays. We profiled the expression of the genes in FACS-enriched cell population and conducted transcriptome analysis.
