    Combining Ferroptosis Induction with MDSC Blockade Renders Primary Tumors and Metastases in Liver Sensitive to Immune Checkpoint Blockade

    Glutathione peroxidase 4 was genetically altered in murine models for hepatocellular carcinoma and colorectal cancer (CRC) to analyze the effect of ferroptosis on tumor cells and the immune tumor microenvironment. Subcutaneously grown CRC organoids were utilized.

    Autophagy Controls Mucus Secretion from Intestinal Goblet Cells by Alleviating ER Stress

    Scientists found that constitutive activation of autophagy in mice via Beclin 1 enabled the production of a thicker and less penetrable mucus layer by reducing endoplasmic reticulum (ER) stress.

    TRIM40 Is a Pathogenic Driver of Inflammatory Bowel Disease Subverting Intestinal Barrier Integrity

    Researchers showed that a subset of patients with inflammatory bowel disease exhibited substantially higher levels of tripartite motif-containing protein 40 (TRIM40), a gene that is hardly detectable in healthy individuals.

    Muc2-Dependent Microbial Colonization of the Jejunal Mucus Layer is Diet Sensitive and Confers Local Resistance to Enteric Pathogen Infection

    Investigators demonstrated that mice fed with a Western-style diet suffered regiospecific failure of the mucus barrier in the small intestinal jejunum caused by diet-induced mucus aggregation.

    RRP15 Deficiency Induces Ribosome Stress to Inhibit Colorectal Cancer Proliferation and Metastasis via LZTS2-Mediated β-Catenin Suppression

    Scientists found that RRP15, a nucleolar protein critical for ribosome biogenesis and checkpoint control, was frequently upregulated in primary colorectal cancers (CRCs), and higher RRP15 expression positively correlated with TNM stage and poor survival of CRC patients.

    MiR-7-5p/KLF4 Signaling Inhibits Stemness and Radioresistance in Colorectal Cancer

    Investigators established two radioresistant colorectal cancer (CRC) cell lines, HCT116-R and RKO-R, using fractionated irradiation to explore the role of cancer stem cells in regulating resistance to radiotherapy in colorectal cancer.

    Spindle Function and Wnt Pathway Inhibition by PBX1 to Suppress Tumor Progression via Downregulating DCDC2 in Colorectal Cancer

    Researchers revealed the anti-tumor function of pre-B-cell leukemia transcription factor 1 (PBX1) in colorectal cancer and the underlying molecular mechanism.

    Targeting BAP1 with Small Compound Inhibitor for Colon Cancer Treatment

    Scientists showed that BRCA1-associated protein-1 (BAP1) was upregulated in colon cancer cells and tissues and that BAP1 depletion reduced colon cancer cell proliferation and tumor growth.

    The Genetics of Non-Monogenic IBD

    The authors provide an overview of the current knowledge about the genetics of non-monogenic inflammatory bowel disease (IBD) and how it differs from the monogenic forms and future perspectives.
