    Impaired Glycosylation of Gastric Mucins Drives Gastric Tumorigenesis and Serves as a Novel Therapeutic Target

    Using a Muc6 knockout mouse model, gastric organoids, and cell lines, the authors proposed that Golgi stress responses and aberrant glycans induced by mucin deletion were important drivers of gastric cancer.

    p53 Promotes Revival Stem Cells in the Regenerating Intestine after Severe Radiation Injury

    Scientists performed single-cell RNA-seq and lineage tracing experiments and demonstrated that transient activation of p53 was required to properly reprogram damaged epithelial cells in response to severe radiation injury to promote tissue regeneration.

    Disruption of Epithelium Integrity by Inflammation-Associated Fibroblasts through Prostaglandin Signaling

    Researchers developed an in vitro model whereby human colon fibroblasts were induced by specific cytokines and recapitulated key features of inflammation-associated fibroblasts in vivo.

    Telomere Dysfunction Alters Intestinal Stem Cell Dynamics to Promote Cancer

    Using an Apc-mutant mouse model, investigators reported that GSK3β inhibition countered the actions of Wnt antagonists on intestinal stem cells, resulting in impaired adenoma formation of telomere dysfunctional Apc-mutant cells.

    AbstractGraphical Abstract

    POLQ Inhibition Attenuates the Stemness and Ferroptosis Resistance in Gastric Cancer Cells via Downregulation of Dihydroorotate Dehydrogenase

    The authors reported that polymerase theta (POLQ), a widely conserved DNA polymerase, positively regulated stem cell-like characteristics of gastric cancer (GC) cells. Knockdown of POLQ suppressed the stemness of GC cells in vitro and in vivo.

    FAM120A Deficiency Improves Resistance to Cisplatin in Gastric Cancer by Promoting Ferroptosis

    Scientists reported that FAM120A was upregulated in gastric cancer (GC) tissues and higher in cisplatin-resistant GC tissues, and its high expression was positively correlated with the poor outcome of GC patients.

    Eunyoung Choi’s Gastric Cancer Research Merits AACR-Debbie’s Dream Funding

    Dr. Eunyoung Choi was an inaugural recipient of an American Association for Cancer Research (AACR)-Debbie’s Dream Foundation Innovation and Discovery Grant. Dr. Choi and her research team seek to evaluate the potential of aberrant fatty acid metabolism as a novel druggable target in gastric cancer.
