    Sirtuin 6 Maintains Epithelial STAT6 Activity to Support Intestinal Tuft Cell Development and Type 2 Immunity

    Researchers reported that intestinal epithelial cell Sirtuin 6 deletion led to impaired tuft cell development and type 2 immunity in response to helminth infection, thereby resulting in compromised worm expulsion.

    The cAMP/PKA/CREB and TGF-β/SMAD4 Pathways Regulate Stemness and Metastatic Potential in Colorectal Cancer Cells

    Investigators revealed the essential roles of ALCAM and PROM1, as well as their upstream regulators, the cAMP/PKA/CREB and TGF-β/SMAD4 pathways, in maintaining the stemness and metastatic potential of colorectal cancer cells.

    Abstract

    MAP7D2 Reduces CD8+ Cytotoxic T Lymphocyte Infiltration through MYH9-HMGB1 Axis in Colorectal Cancer

    Through next generation sequencing, scientists identified microtubule-associated protein 7 domain 2 (MAP7D2) as an exploitable therapeutic maneuver to improve the efficacy of immune checkpoint inhibitors for microsatellite stable colorectal cancer therapy.

    CPEB3 Suppresses Gastric Cancer Progression by Inhibiting ADAR1-Mediated RNA Editing via Localizing ADAR1 mRNA to P Bodies

    Cytoplasmic polyadenylation element-binding protein 3 (CPEB3) suppressed gastric cancer cell proliferation, invasion and migration in vitro, as well as tumor growth and metastasis in vivo.

    Abstract

    Modeling Biochemical Gradients In Vitro to Control Cell Compartmentalization in a Microengineered 3D Model of the Intestinal Epithelium

    The authors presented a new in vitro model of the small intestine based on primary epithelial cells, apically accessible, with native tissue mechanical properties and controlled mesh size, 3D villus-like architecture, and precisely controlled biomolecular gradients of the intestinal stem cell niche.

    Abstract

    Chemically-Modified MIR143-3p Exhibited Anti-Cancer Effects by Impairing the KRAS Network in Colorectal Cancer Cells

    Researchers investigated the mechanistic advantages of MIR143-3p in various KRAS mutant colorectal cancer cell lines.

    3D Matrix Promotes Cell Dedifferentiation into Colorectal Cancer Stem Cells via Integrin/Cytoskeleton/Glycolysis Signaling

    The 3D extracellular matrix could mediate cytoskeletal F-actin bundling through biomechanical force associated receptors integrin β1, contributing to the release of E3 ligase Tripartite motif protein 11 from cytoskeleton and degradation of the glycolytic rate-limiting enzyme phosphofructokinase.

    Abstract

    MCPIP1 Suppresses the NF-κB Signaling Pathway through Negative Regulation of K63-Linked Ubiquitylation of TRAF6 in Colorectal Cancer

    Overexpressed monocyte chemotactic protein-induced protein 1 (MCPIP1) was found to inhibit the proliferative and migratory abilities of colorectal cancer cells, whereas knockdown of MCPIP1 produced the opposite result.

    Abstract

    Transmissible Gastroenteritis Virus Infection Promotes the Self-Renewal of Porcine Intestinal Stem Cells via Wnt/β-Catenin Pathway

    Scientists showed that transmissible gastroenteritis virus infection initiated interferon and inflammatory responses following the loss of absorptive enterocytes and goblet cells, but did not disturb epithelial integrity but induced the proliferation of intestinal stem cells.

    Abstract

    Intensification of Resveratrol Cytotoxicity, Pro-Apoptosis, Oxidant Potentials in Human Colorectal Carcinoma HCT-116 Cells Using Zein Nanoparticles

    Investigators explored the antiproliferative, pro-apoptotic, and oxidative stress potentials of resveratrol-Zein nanoparticles versus resveratrol against human colorectal carcinoma HCT-116 cells.
