    IRF3
    Prevents Colorectal Tumorigenesis via Inhibiting the Nuclear Translocation of β-Catenin

    Genetic ablation of IRF3 profoundly promoted the proliferation of intestinal epithelial cells via aberrantly activating Wnt signaling.

    HMGB1
    Released from GSDME-Mediated Pyroptotic Epithelial Cells Participates in the Tumorigenesis of Colitis-Associated Colorectal Cancer through the ERK1/2 Pathway

    In vitro experiments demonstrated that high-mobility group box protein 1 (HMGB1) induced proliferation and proliferating cell nuclear antigen expression in CT26 colon cancer cells through the ERK1/2 pathway.

    Loss
    of Interleukin-17 Receptor D Promotes Chronic Inflammation-Associated Tumorigenesis

    Investigators showed that genetic disruption of interleukin-17 receptor D (Il17rd) led to the increased formation of spontaneous tumors in multiple tissues of aging mice. Loss of IL-17RD also promoted tumor development in a model of colitis-associated colorectal cancer, associated with an exacerbated inflammatory response.

    Abstract

    Synthetic
    Lethality between MyD88 Loss and Mutations in Wnt/β-Catenin Pathway in Intestinal Tumor Epithelial Cells

    The authors clarified the mechanisms by which epithelial MyD88 contributes to intestinal tumor formation and addressed whether MyD88 can be a therapeutic target of colorectal cancer.

    Abstract

    Exosomal
    miR-590-3p Derived from Cancer-Associated Fibroblasts Confers Radioresistance in Colorectal Cancer

    High expression of miR-590-3p and low expression of CLCA4 was found in both colorectal cancer (CRC) tissues and cell lines. CLCA4 was indicated as a target gene of miR-590-3p. CAF-derived exosomes were extracted and co-cultured with CRC cells which were then exposed to radiation.

    LncRNA
    NEAT1 Remodels Chromatin to Promote the 5-Fu Resistance by Maintaining Colorectal Cancer Stemness

    The authors observed that lncRNA NEAT1 was associated with 5-fluorouracil (5-Fu) resistance in colorectal cancer. They showed that NEAT1 promoted 5-Fu resistance in colorectal cells.

    SHP2
    Regulates the Development of Intestinal Epithelium by Modifying OSTERIX+ Crypt Stem Cell Self‐Renewal and Proliferation

    OSTERIX, an OB‐specific zinc finger‐containing transcription factor was for the first time found to be expressed in gastrointestinal crypt cells, and SHP2 expression in the crypt Osx+ cells was critical for self‐renewal and proliferation.

    Mesenchymal
    Stroma/Stem‐Like Cells of GARP Knockdown Inhibits Cell Proliferation and Invasion of Mouse Colon Cancer Cells (MC38) through Exosomes

    The authors explored the therapy role of mesenchymal stroma/stem‐like cell‐derived exosomes targeting glycoprotein A repetition predominant (GARP) in mouse colon cancer cell MC38.

    Increase
    in Epithelial Permeability and Cell Metabolism by High Mobility Group Box 1, Inflammatory Cytokines and TPEN in Caco-2 Cells as a Novel Model of Inflammatory Bowel Disease

    Caco-2 cells in 2D culture and 2.5D Matrigel culture were pretreated with transforming growth factor-β type 1 receptor kinase inhibitor EW-7197, epidermal growth factor receptor kinase inhibitor AG-1478 and a TNFα antibody before treatment with HMGB1 and inflammatory cytokines.

    The Roles and Functions of Paneth Cells in Crohn’s Disease: A Critical Review

    Paneth cells are located at the base of small intestinal crypts and secrete the α‐defensins, human α‐defensin 5 and human α‐defensin 6 in response to bacterial, cholinergic and other stimuli.

    Light Chain Kinase Regulates Intestinal Permeability of Mucosal Homeostasis in Crohn’s Disease

    Researchers investigated the potential role of intestinal permeability in Crohn’s disease pathogenesis. Intestinal permeability is usually mediated by cytoskeleton and intercellular junctions.
