    Activation of FXR and Inhibition of EZH2 Synergistically Inhibit Colorectal Cancer through Cooperatively Accelerating FXR Nuclear Location and Upregulating CDX2 Expression

    Scientists found that the expression of farnesoid X receptor (FXR) was negatively correlated with enhancer of zeste homolog 2 (EZH2) in colon cancer tissues.

    Exosomal miR-146a-5p and miR-155-5p Promote CXCL12/CXCR7-Induced Metastasis of Colorectal Cancer by Crosstalk with Cancer-Associated Fibroblasts

    The authors found a significant positive correlation between C-X-C motif chemokine receptor 7 (CXCR7) expression and cancer-associated fibroblast activation markers in colonic tissues from clinical specimens and in villinCXCR7 transgenic mice.

    HECTD3 Promotes Gastric Cancer Progression by Mediating the Polyubiquitination of c-MYC

    Scientists discovered that HECTD3 was abnormally activated in gastric cancer, and the clinical prognosis database suggested that HECTD3 was strongly expressed in gastric cancer.

    Abstract

    SNORD1C Maintains Stemness and 5-FU Resistance by Activation of Wnt Signaling Pathway in Colorectal Cancer

    Investigators suggested that SNORD1C functioned via the Wnt/β-catenin pathway to enhance cancer cell stemness in colorectal cancer and could be a predictive biomarker for the prognosis ad aggressiveness of this malignancy.

    Baicalin Regulates Autophagy to Interfere with Small Intestinal Acute Graft-versus-Host Disease

    Investigators established a mouse model of acute graft-versus-host disease (aGVHD) to verify whether baicalin could protect the small intestinal mucosal barrier by regulating abnormal autophagy and interfering with intestinal aGVHD.

    Cold Exposure Induces Intestinal Barrier Damage and Endoplasmic Reticulum Stress in the Colon via the SIRT1/Nrf2 Signaling Pathway

    Scientists found that cold exposure damaged the morphology and structure of the colon, destroyed the tight junctions of the colonic epithelial tissue, and promoted inflammation of the colon.

    The Gut Microbial Metabolite Formate Exacerbates Colorectal Cancer Progression

    Researchers showed that formate, a metabolite produced by colorectal cancer (CRC)-associated bacterium Fusobacterium nucleatum, promoted CRC development and that microbiome-derived formate drove CRC tumor invasion by triggering aryl hydrocarbon receptor signaling while increasing cancer stemness.

    Impacts and Mechanisms of Metabolic Reprogramming of Tumor Microenvironment for Immunotherapy in Gastric Cancer

    The authors discuss how metabolic reprogramming of gastric cancer (GC) cells and immune cells involved in GC immune responses modulate anti-tumor immune responses, as well as the effects of gastrointestinal flora in tumor microenvironment and GC.

    Modulation of Radiation-Induced Intestinal Injury by Radioprotective Agents: A Cellular and Molecular Perspectives

    Investigators highlight the cellular and molecular interruptions of the gastrointestinal (GI) system due to acute and chronic GI radiation injury, the role of radioprotectors in signaling cascade modulations in GI epithelium and the involvement of intestinal stem cells markers in radioprotection.
