    Corticosteroids Impair Epithelial Regeneration in Immune-Mediated Intestinal Damage

    Investigators reported that corticosteroids directly targeted intestinal epithelium, potentially worsening immune-mediated gastrointestinal damage. Corticosteroids administered to mice in vivo and intestinal organoid cultures ex vivo reduced epithelial proliferation.

    EFHD2 Suppresses Intestinal Inflammation by Blocking Intestinal Epithelial Cell TNFR1 Internalization and Cell Death

    Scientists reported that EF-hand domain-containing protein D2 (EFHD2), highly expressed in normal intestine tissues but decreased in intestinal biopsy samples of ulcerative colitis patients, protected intestinal epithelium from TNF-induced intestinal epithelial cell apoptosis.

    Phosphorylation-Dependent Deubiquitinase OTUD3 Regulates YY1 Stability and Promotes Colorectal Cancer Progression

    Investigators screened for ubiquitin-specific proteases that interacted with yin yang 1 (YY1), and identified ovarian tumor protease family member (OTUD3) as a deubiquitinase for YY1.

    Abstract

    Cold Atmospheric Plasma Stabilizes Mismatch Repair for Effective, Uniform Treatment of Diverse Colorectal Cancer Cell Types

    The authors reported that cold atmospheric plasma treatment induced comparable effects on apoptosis, reactive oxygen species and reactive nitrogen species, as well as the expression of apoptosis-related proteins in both microsatellite instability and microsatellite stability cells.
