    Inflammation Promotes Resistance to Immune Checkpoint Inhibitors in High Microsatellite Instability Colorectal Cancer

    The authors demonstrated that in patients with microsatellite high-instability colorectal cancer and a local inflammatory condition, the primary tumor progressed but its liver metastasis regressed upon Pembrolizumab treatment.

    Small Noncoding Vault RNA2-1 Disrupts Gut Epithelial Barrier Function via Interaction with HuR

    Researchers identified vtRNA2-1 as a novel regulator of the intestinal barrier via interaction with RNA-binding protein HuR.

    ARD1 Stabilizes NRF2 through Direct Interaction and Promotes Colon Cancer Progression

    ARD1 was found to possibly potentiate the oncogenic function of NRF2 in human colon cancer by stabilizing the transcription factor.

    Abstract

    m6A-Modified circFNDC3B Inhibits Colorectal Cancer Stemness and Metastasis via RNF41-Dependent ASB6 Degradation

    Scientists demonstrated that YTHDC1 facilitated cytoplasmic export of m6A-modified circFNDC3B, thereby suppressing stem-like and metastatic properties of colorectal cells.

    Ciclopirox Drives Growth Arrest and Autophagic Cell Death through STAT3 in Gastric Cancer Cells

    Researchers found that ciclopirox dramatically suppressed gastric cancer xenograft growth in vitro via inhibiting proliferation and stimulating autophagic cell death rather than apoptosis.

    Differential Involvement of LUBAC-Mediated Linear Ubiquitination in Intestinal Epithelial Cells and Macrophages during Intestinal Inflammation

    Scientists used two experimental mouse models of inflammatory bowel diseases to examine the role of linear ubiquitination in intestinal epithelial cells and macrophages during intestinal inflammation.
    [Journal of Pathology]

    Abstract

    Nanoparticle-Mediated PRDX2 Inhibition for Specific Targeting of CHK2-Null Colorectal Cancer

    Investigators targeted the synthetic lethal interaction between PRDX2 and CHK2 in colorectal cancer cells using N-Carbamoyl alanine-loaded chitosan nanoparticles to selectively inhibit the CHK2-null HCT116 cells.

    Knockdown of Membrane-Bound Complement Regulatory Proteins Suppresses Colon Cancer Growth in Mice through Inducing Tumor Cell Apoptosis

    Membrane-bound complement regulatory proteins (mCRPs) expression in human colon cancer cells were upregulated by STAT3/STAT6/p38 MAPK signaling and mCRPs knockdown reduced colon cancer growth in mice through inducing tumor cell apoptosis.

    Abstract

    Gastric Cancer Stem Cell-Derived Exosomes Promoted Tobacco Smoke-Triggered Development of Gastric Cancer by Inducing the Expression of Circ670

    Scientists provided a new insight into tobacco smoke promoting the progression of gastric cancer, demonstrating that tobacco smoke-induced exosomes promoted the spheroidizing ability, stemness genes expression, and epithelial-mesenchymal transition process of gastric cancer stem cells.
