Expression Profiling Identifies Novel Gene Targets and Functions for Pdx1 in the Duodenum of Mature Mice

Project description:Transcription factor pancreatic and duodenal homeobox 1 (Pdx1) plays an essential role in the pancreas to regulate its development and maintain proper islet function. However, less is known about the function of Pdx1 in the small intestine. We aim to investigate the role of Pdx1 in mature proximal small intestine by profiling the expression of genes differentially regulated in response to Pdx1 inactivation restricted to the intestinal epithelium in mice. Pdx1 was conditionally inactivated in the intestinal epithelium of Pdx1flox/flox;VilCre mice, by crossing mutant mice homozygous for loxP site-flanked Pdx1 alleles with transgenic mice expressing Cre recombinase under the control of the mouse villin 1 gene promoter. Total RNA was isolated from the first five centimeters of the small intestine from adult Pdx1flox/flox;VilCre and littermate control mice. Microarray analysis was performed to investigate genome-wide transcriptional profiles in the proximal small intestine.

Metabolites in contents of small intestine in wild type and DAOG181R/G181R mice

Project description:To investigate if DAO regulates metabolites in intestinal lumen, we compared metabolites in contents of small intestine in wild type and DAOG181R/G181R mice. All mice have C57BL/6 background and 8 weeks of age.

Intestinal crypt stem and transit cell proliferation and villus cell migration in mice lacking Klf9

Project description:Krüppel-like factor 9 (Klf9), a zinc-finger transcription factor, is implicated in the control of cell proliferation, cell differentiation and cell fate in brain and uterus. Using Klf9 null mutant mice, we have investigated the involvement of Klf9 in small intestine crypt-villus cell renewal and lineage determination. We report the predominant expression of Klf9 gene in small intestine smooth muscle (muscularis externa). Jejunums null for Klf9 have shorter villi, reduced crypt stem/transit cell proliferation, and altered lineage determination as indicated by decreased and increased numbers of Goblet and Paneth cells, respectively. A stimulatory role for Klf9 in villus cell migration was demonstrated by BrdU labeling. Results suggest that Klf9 controls the elaboration, from small intestine smooth muscle, of molecular mediator(s) of crypt cell proliferation and lineage determination, and of villus cell migration.

Global gene expression profile of small intestine from wild-type and NKCC1 (SLC12A2)-knockout mice.

Project description:The objective of this study was to identify changes in gene expression levels between wild-type and NKCC1-knockout small intestine. 6 wild-type and 6 NKCC1-knockout small intestine RNA samples were compared. Total RNA was collected from both male and female 8-week old wild-type and NKCC1-null mice on an inbred FVB\N background. All comparisons were done between wild-type and NHE4-null samples from age- and gender-matched mice.

Experiment Overall Design: Total RNA was extracted in parallel from the jejunums of five WT and five Klf9-/- male mice (PND 30) using TRIzol reagent (Invitrogen, Carlsbad, CA). Conversion of each RNA preparation to corresponding fragmented cRNA. Fifteen ug of each cRNA was hybridized for 16 hours to an Affymetrix mouse 430A GeneChip. Ten GeneChips (each corresponding to a single animal) were hybridized, washed and scanned in parallel. Following the wash, signal amplification, and signal detection steps, GeneChips were scanned (Agilent GeneArray laser scanner) and the resultant images quantified using Affymetrix MAS 5.0 software.

RNA-Seq analysis of mouse small intestine enteroendocrine cells

Project description:We generated knock-in mice expressing GFP under the control of the endogenous GIP (Glucose-dependent Insulinotropic Polypeptide) promoter that enable the isolation of a purified population of small intestine K cells. Using RNA-Seq, we comprehensively characterized the transcriptomes of GIP-GFP cells as well as the entire enteroendocrine lineage derived from Neurogenin3 (Ngn3)-expressing progenitors. We interrogated the whole transcriptome of FACS-isolated small intestine GIPGFP cells using high-throughput mRNA sequencing. We also obtained the global gene expression patterns of the entire enteroendocrine cell lineage as well as the non-enteroendocrine cell population, comprising enterocytes, goblet cells and Paneth cells. To achieve this, small intestine epithelial cells from male mice resulting from the breeding of Neurogenin3 (Ngn3)-Cre mice with ROSA26-LoxP-STOP-LoxP-tomato indicator mice were isolated based on Tomato fluorescence and negative staining for CD45. Due to the small cell numbers, we constructed each of the three RNA-Seq libraries (GIPGFP, Ngn3TOMATO, and Ngn3-) using a pool of equal amounts of individual RNA samples without RNA amplification.
