    TOP STORY

    Targeting SOX13 Inhibits Assembly of Respiratory Chain Supercomplexes to Overcome Ferroptosis Resistance in Gastric Cancer

    Investigators showed that SOX13 boosted protein remodeling of electron transport chain complexes by directly transactivating SCAF1. This led to increased supercomplex assembly, mitochondrial respiration, mitochondrial energetics and chemo- and immune-resistance.

    Reduction of Specific Enterocytes from Loss of Intestinal LGR4 Improves Lipid Metabolism in Mice

    Scientists reported that deficiency of Lgr4 in intestinal epithelium decreased the proportion of enterocytes selective for long-chain fatty acid absorption, leading to reduction in lipid absorption and subsequent improvement in lipid and glucose metabolism.

    Development and Interpretation of a Pathomics-Driven Ensemble Model for Predicting the Response to Immunotherapy in Gastric Cancer

    Researchers developed and validated a pathomics-driven ensemble model for predicting the response to immune checkpoint inhibitors in gastric cancer, using H&E-stained whole slide images.

    Abstract

    RAF1 Facilitates KIT Signaling and Serves as a Potential Treatment Target for Gastrointestinal Stromal Tumor

    Investigators reported that inhibition of RAF1 suppressed the activation of both wild-type KIT and primary KIT mutations in gastrointestinal stromal tumor, with primary KIT mutations showing greater sensitivity.

    Abstract

    NUP43 Promotes PD-L1/nPD-L1/PD-L1 Feedback Loop via TM4SF1/JAK/STAT3 Pathway in Colorectal Cancer Progression and Metastatsis

    Scientists reported that the oncogenic factor nucleoporin 43 (NUP43) impacted the process of programmed cell death-ligand 1 (PD-L1) nuclear translocation by regulating the expression level of the PD-L1 chaperone protein Importin 5.

    RUNX1-Induced Upregulation of PTGS2 Enhances Cell Growth, Migration and Invasion in Colorectal Cancer Cells

    Researchers explored the upstream transcription factors responsible for elevating prostaglandin-endoperoxide synthase 2 (PTGS2) expression in coloretal cancer (CRC) cells. PTGS2 silencing repressed cell growth, migration and invasion in CRC cells.

    Navigating the Complexities of Drug Development for Inflammatory Bowel Disease

    The authors review current challenge in inflammatory bowel disease drug discovery, and examine how advances in machine learning and tissue engineering could be used at the preclinical stage where attrition rates are high.

    UZ Brussel-VUB Receive €2.5M for Research into Pioneering Cancer Treatment Technique

    The Vrije Universiteit Brussel (VUB) has been awarded a €2.5 million grant to further research FLASH radiation. This new technique means that a cancer patient needs to be treated with radiation only once, instead of dozens of time. The research will first be offered to people with skin cancer, rectal cancer and sarcomas.
