    The RNA Helicase Dhx15 Mediates Wnt-Induced Antimicrobial Protein Expression in Paneth Cells

    Scientists investigated the in vivo role of DEAD-box Helicase 15 (Dhx15) in intestinal antibacterial responses by generating mice that were intestinal epithelial cell-specific deficient for Dhx15.

    Three-Dimensional Interactions between Enhancers and Promoters during Intestinal Differentiation Depend upon HNF4

    Researchers applied chromosome conformation capture combined with chromatin immunoprecipitation and sequencing to measure enhancer-promoter interactions in progenitor and differentiated cells of the intestinal epithelium.

    Cdk5rap3 Is Essential for Intestinal Paneth Cell Development and Maintenance

    Paneth cell-specific knockout of Cdk5rap3 caused partial loss of Paneth cells, while inducible acute deletion of Cdk5rap3 resulted in disassembly of the rough endoplasmic reticulum and abnormal zymogen granules in the mature Paneth cells, as well as loss of Paneth cells.

    RNA Binding Protein PUM1 Promotes Colon Cancer Cell Proliferation and Migration

    Investigators found that pumilio-1 (PUM1) mRNA expression was high in primary and metastatic colon cancer cell lines when compared to the normal colon cell line.

    Abstract

    The Inhibitory Effect of Human DEFA5 in Growth of Gastric Cancer by Targeting BMI‐1

    α‐Defensin 5 (DEFA5) directly bound with BMI‐1, which subsequently decreased its binding at the CDKN2a locus and upregulated the expression of two cyclin‐dependent kinase inhibitors, p16 and p19.

    Abstract

    Mutational Inactivation of Apc in the Intestinal Epithelia Compromises Cellular Organisation

    Using in vivo and organoid models of intestinal epithelial tumorigenesis, scientists found that Wnt pathway activity controls intestinal epithelial villi and crypt structure, morphological features lost upon adenomatous polyposis coli inactivation.

    New Insights and Enhanced Human Norovirus Cultivation in Human Intestinal Enteroids

    Human intestinal stem cell-derived enteroids did not support virus replication from every human norovirus-positive stool sample, which led the authors to test and optimize new medium conditions, identify characteristics of stool samples that allow replication, and evaluate consistency of replication over time.

    Surfactant Protein A Reduces TLR4 and Inflammatory Cytokine mRNA Levels in Neonatal Mouse Ileum

    Surfactant protein A reduced expression of toll-like receptor 4 (TLR4) and proinflammatory cytokines in normal human intestinal epithelial cells.

    Farnesyl Dimethyl Chromanol Targets Colon Cancer Stem Cells and Prevents Colorectal Cancer Metastasis

    Investigators provided the first demonstration that farnesyl dimethyl chromanol inhibited colon cancer stem cell viability, survival, self-renewal, pluripotent transcription factors expression, organoids formation, and Wnt/β-catenin signalling, as evidenced by comparisons with vehicle-treated controls.
