(Submitter supplied) To determine whether the intestine-restricted transcription factor (TF) CDX2 functionally interacts with the endoderm-wide TF HNF4A, we crossed tissue-specific conditional Cdx2 and Hnf4a knockout mice to generate compound mutant mice. We used RNA-sequencing to profile gene expression changes in compound mutant mice compared to control mice. The compound mutant mice had a significantly worse phenotype than either single mutant, and gene expression was significantly perturbed in compound mutants compared to control mice.

(Submitter supplied) Although hepatocyte-nuclear-factor-1α (Hnf1α) is crucial for pancreas and liver functions, it is believed to play a limited functional role for intestinal epithelial functions. The aim of this study was to assess the consequences of abrogating Hnf1α on the maintenance of adult small intestinal epithelial functions. Methodology/Principal Findings An Hnf1α knockout mouse model was used. Assessment of histological abnormalities, crypt epithelial cell proliferation, epithelial barrier, glucose transport and signalling pathways were measured in these animals. more...

(Submitter supplied) GATA6 is a transcription factor involved in the differentiation of intestinal epithelial cells into differentiated absorptive epithelial cells.

(Submitter supplied) Stomach and intestinal adult epithelia harbor stem cells that are responsible for their continuous regeneration. Stomach and intestinal stem cells differ in their differentiation program and in the gene repertoire that they express. We show that single adult Lgr5-positive stem cells, isolated from 3D cultured small intestinal organoids, require Cdx2 to maintain their intestinal identity and are converted cell-autonomously into stomach-pyloric stem cells in the absence of this transcription factor.

(Submitter supplied) Genes encoding transcription factors function as hubs in gene regulatory networks because they encode DNA-binding proteins, which bind to promoters that carry their binding sites. In the present work we have studied gene regulatory networks defined by genes with transcripts belonging to different mRNA abundance classes in the small intestinal epithelial cell. The focus is the rewiring that occurs in transcription factor hubs in these networks during the differentiation of the small intestinal epithelial cell while it migrates along the crypt-villus axis and during its development from a fetal endodermal cell to a mature adult villus epithelial cell. more...

(Submitter supplied) To define target genes of the intestine-restricted transcription factor (TF) CDX2 in intestinal stem cells, we performed chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq). We used RNA-sequencing to profile gene expression changes during cell differentiation from mouse intestinal stem cells to mature villus cells, as well as genes perturbed in intestinal stem cells upon loss of Cdx2. more...

(Submitter supplied) Important lineage regulators, such as the intestinal lineage regulator CDX2, can function over the timespan of intestinal development. The consequences of CDX2 knockout in the embryo versus in the adult are quite distinct. The data below provide a rationale for these divergent transcription factor functions in distinct developmental contexts, with unique binding patterns of CDX2 observed via ChIP-seq and unique gene regulatory targets defined via RNA-seq. more...

(Submitter supplied) Cell differentiation requires epigenetic modulation of tissue-specific genes and activities of master transcriptional regulators, which are recognized for their dominant control over cellular programs. Using novel epigenomic methods, we characterized enhancer elements specifically modified in differentiating intestinal epithelial cells and found enrichment of transcription factor-binding motifs corresponding to CDX2, a master regulator of the intestine. more...

(Submitter supplied) We conditionally inactivated mouse Cdx2, a dominant regulator of intestinal development, and mapped its genome occupancy in adult intestinal villi. Although homeotic transformation, observed in Cdx2-null embryos, was absent in mutant adults, gene expression and cell morphology were vitally compromised. Lethality was accelerated in mice lacking both Cdx2 and its homolog Cdx1, with exaggeration of defects in crypt cell replication and enterocyte differentiation. more...

(Submitter supplied) This is the first report to document circadian rhythmicity of specific microRNAs in rat jejunum. Our data provide a link between the anti-proliferative microRNA miR-16 and the intestinal proliferation rhythm and point to miR-16 as an important regulator of proliferation in jejunal crypts. This function may be essential to match proliferation and absorptive capacity with nutrient availability.

(Submitter supplied) Abstract: The intestinal epithelium is replaced weekly by non-quiescent stem cells with kinetics that rely on a rapid loss of stemness and choice for secretory or absorptive lineage differentiation. To determine how the cellular transcriptome and proteome changes during these transitions, we developed a new cell sorting method to purify stem cells, secretory and absorptive progenitor cells, and mature, differentiated cells. more...
