    CD147 Receptor Is Essential for TFF3-Mediated Signaling Regulating Colorectal Cancer Progression

    Via binding to CD147, TFF3 enhanced CD147-CD44s interaction, resulting in signal transducer and activator of transcription 3 activation and prostaglandin G/H synthase 2 expression, which were indispensable for TFF3-induced colorectal cancer migration, proliferation, and invasion.

    Artificial Intelligence Guided Discovery of a Barrier-Protective Therapy in Inflammatory Bowel Disease

    Investigators used machine-learning to pinpoint a path of continuum states which most effectively predicted disease outcome and was enriched in gene clusters that maintained the integrity of the gut epithelial barrier. Potential for treatment efficacy was confirmed in patient-derived organoids.

    CDK15 Promotes Colorectal Cancer Progression via Phosphorylating PAK4 and Regulating β-Catenin/ MEK-ERK Signaling Pathway

    Knockdown of CDK15 suppressed cell proliferation and anchorage-independent growth of colorectal cancer cells and inhibited tumor growth in cell line-derived xenograft model.

    Abstract

    Telomere Dysfunction Instigates Inflammation in Inflammatory Bowel Disease

    In murine intestinal epithelium with telomere dysfunction, DNA damage-induced activation of ataxia-telangiectasia mutated (ATM) resulted in ATM-mediated phosphorylation and activation of the YAP1 transcriptional coactivator, which in turn up-regulated pro-IL-18, a pivotal immune regulator in IBD pathogenesis.

    Abstract

    CRIP1 Cooperates with BRCA2 to Drive the Nuclear Enrichment of RAD51 and to Facilitate Homologous Repair upon DNA Damage Induced by Chemotherapy

    CRIP1 downregulation caused homologous recombination repair deficiency with concomitant increase in cell sensitivity to cisplatin, epirubicin, and the poly ADP-ribose polymerase inhibitor olaparib in gastric cancer cells.

    PGE2-JNK Signaling Axis Non-Canonically Promotes Gli Activation by Protecting Gli2 from Ubiquitin-Proteasomal Degradation

    Colorectal cancer cells hijacked prostaglandin E2 (PGE2) to non-canonically promote Hedgehog transcriptional factor Gli activity and Gli-dependent proliferation of colorectal cancer cells in a Smo-independent manner.

    Diosmetin Has Therapeutic Efficacy in Colitis Regulating Gut Microbiota, Inflammation, and Oxidative Stress via the Circ-Sirt1/Sirt1 Axis

    Diosmetin administration significantly decreased disease activity index score and ameliorated microscopic colon tissue damage, increased the expression of tight junction proteins, and reduced the secretion of proinflammatory cytokines IL-1β, IL-6, TNF-α, and Cox-2 in colon tissue.

    Abstract

    Integrated Whole Transcriptome and Small RNA Analysis Revealed Multiple Regulatory Networks in Colorectal Cancer

    The authors conducted a computational analysis using Ingenuity Pathway Analysis to identify multiple activated signaling networks in colorectal cancer (CRC), while functional annotation highlighted activation of cell proliferation and migration as the hallmark of CRC.

    Immunomodulatory Role of Parkinson’s Disease 7 in Inflammatory Bowel Disease

    Researchers determined the expression and localization of Parkinson’s disease 7 in the colon biopsies of children with IBD, in the colon of dextran sodium sulphate treated mice, and in HT-29 colonic epithelial cells.

    Persistence of Lgr5+ Colonic Epithelial Stem Cells in Mouse Models of Inflammatory Bowel Disease

    Direct exposure of colonic epithelial organoids to dextran sulfate sodium, oxazolone, or TNBS resulted in increased apoptosis and loss of Lgr5+ cells. Targeted ablation of Lgr5+ cells resulted in severe exacerbation of chronic, antibody-induced IL-10-deficient colitis, but had only modest effects in TNBS-induced colitis.

    LINC01287 Facilitates Proliferation, Migration, Invasion and EMT of Colon Cancer Cells via miR-4500/MAP3K13 Pathway

    The potential functions of long intergenic non-protein coding RNA 1287 (LINC01287) were evaluated by cell viability assay, colony formation assay, soft agar assay, flow cytometry, transwell migration and invasion assay, and tumor xenograft growth in colon cancer cells.

    Overexpression of miR-122 Impairs Intestinal Barrier Function and Aggravates Acute Pancreatitis by Downregulating Occludin Expression

    Scientists studied the mechanism of miR-122 in regulating intestinal barrier function in acute pancreatitis (AP). AP rat model was constructed via intraperitoneal injection of ketamine, and primary intestinal epithelial cells were isolated from rats for in vitro studies.

    Tumor Heterogeneity and Evolutionary Dynamics in Colorectal Cancer

    Recent advances have investigated the ecological and evolutionary processes which transform normal cells into cancer. The authors describe the role which driver mutations play in the Vogelstein model and subsequently demonstrate the evidence which supports a more complex model.

    Interference of Dietary Polyphenols with Potentially Toxic Amino Acid Metabolites Derived from the Colonic Microbiota

    Varying amounts of undigested or partially digested proteins reach the colon where they are metabolized by the microbiota, resulting in the formation of various compounds. In humans, their accumulation is potentially harmful, and it has been proposed that they could be involved in the development of pathologies such as colorectal cancer and ulcerative colitis.
