    Abstract

    USP10/XAB2/ANXA2 Axis Promotes DNA Damage Repair to Enhance Chemoresistance to Oxaliplatin in Colorectal Cancer

    Colorectal cancer cells treated with oxaliplatin exhibited increased ubiquitin-specific protease 10 (USP10) nuclear expression. USP10 bound to XPA binding protein 2 (XAB2) and deubiquitinated XAB2 K48-linked polyubiquitination at K593, thereby stabilizing XAB2 by reducing its degradation.

    KLF6-Mediated Recruitment of the P300 Complex Enhances H3K23su and Cooperatively Upregulates SEMA3C with FOSL2 to Drive 5-FU Resistance in Colon Cancer Cells

    Researchers demonstrated that histone 3 lysine 23 succinylation (H3K23su) was a critical epigenetic determinant of 5-fluorouracil (5-FU) resistance in colon cancer cells, exerting its effects through the modulation of critical genes and transcription factors.

    Transcription Factor ELF-1 Protects against Colitis by Maintaining Intestinal Epithelium Homeostasis

    Scientists demonstrated that E74-like factor 1 (ELF-1) deficiency in mice led to exacerbated DSS-induced colitis, marked by inflammation dominated by neutrophil infiltration and activation of IL-17 signaling pathways in various immune cells, including Th17, ILC3, γδT, and NKT cells.
