    Fructose-1,6-Bisphosphatase 1 Dephosphorylates IκBα and Suppresses Colorectal Tumorigenesis

    Scientists revealed a previously unrecognized role of fructose 1,6-bisphosphate (FBP1) as a protein phosphatase and established the critical role of FBP1-mediated IκBα dephosphorylation in colorectal tumorigenesis.

    A DLG1-ARHGAP31-CDC42 Axis Is Essential for the Intestinal Stem Cell Response to Fluctuating Niche Wnt Signaling

    Investigators reported that discs large 1 (Dlg1), although dispensable for polarity and cellular turnover during intestinal homeostasis, were required for intestinal stem cell survival in the context of increased Wnt signaling.

    Metformin Acts in the Gut and Induces Gut-Liver Crosstalk

    Researchers showed that in hyperglycemic conditions, metformin increased basolateral intestinal glucose uptake, and its metabolites produced in the gut, through the portal vein reach the liver and reduce hepatic glucose production.

    CircIFNGR2 Enhances Proliferation and Migration of CRC and Induces Cetuximab Resistance by Indirectly Targeting KRAS via Sponging to MiR-30b

    To study the mechanism of cetuximab resistance in KRAS wild-type colorectal cancer (CRC) patients, scientists evaluated the impact of circIFNGR2 on CRC and detected the association among circIFNGR2, miR-30b, and KRAS via various experiments such as cell functional experiments.

    Aspirin Increases Chemosensitivity of Colorectal Cancer Cells and Inhibits the Expression of Toll-Like Receptor 4

    Scientists observed the role of aspirin on the chemotherapy resistance of colorectal cells by CCK8 assay. They found that aspirin could effectively enhance the chemosensitivity of CT26 and HCT116 colorectal cancer cell lines.

    Protective Effect of Electroacupuncture on the Barrier Function of Intestinal Injury in Endotoxemia through HO-1/PINK1 Pathway-Mediated Mitochondrial Dynamics Regulation

    Researchers tested whether electroacupuncture could protec intestinal epithelial cells in patients with endotoxemia by regulating the mitochondrial fusion/fission dynamics, and protect the intestinal barrier by activating the HO-1/PINK1 pathway.

    Folic Acid-Modified Lactoferrin Nanoparticles Coated with a Laminarin Layer Loaded Curcumin with Dual-Targeting for Ulcerative Colitis Treatment

    Given the targeting action of lactoferrin (LF) by binding to the LF receptors of intestinal epithelial cells and of folic acid (FA) by binding to the FA receptors of macrophages, investigators developed an oral dual-targeting nanosystem.
