    An Intestinal Th17 Subset Is Associated with Inflammation in Crohn’s Disease and Activated by Adherent-Invasive Escherichia coli (AIEC)

    Investigators identified and characterized a novel, potentially colitogenic subset of Th17-cells in the intestine of patients with Crohn’s Disease.

    Abstract

    Cancer Associated Fibroblast Derived SLIT2 Drives Gastric Cancer Cell Metastasis by Activating NEK9

    Researchers demonstrated that SLIT2, an axon guidance protein, produced by CAFs and promoted gastric cancer metastasis in two gastric cancer cell lines by binding to roundabout guidance receptor 1.

    WFDC3 Inhibits Tumor Metastasis by Promoting the ERβ-Mediated Transcriptional Repression of TGFBR1 in Colorectal Cancer

    Scientists identified WFDC3 as a tumor suppressor that facilitates estrogen-induced inhibition of metastasis through the estrogen receptor β/TGFBR1 signaling axis. WFDC3 interacts with ERβ and increases its protein stability by inhibiting its proteasome-dependent degradation.

    P62/SQSTM1 Binds with Claudin-2 to Target for Selective Autophagy in Stressed Intestinal Epithelium

    Researchers examined if an interplay between autophagy and claudin-2 protects from colitis and associated epithelial injury. Crypt culture and intestinal epithelial cells are subjected to stress, including starvation or DSS, the chemical that induces colitis in-vivo.

    Dermatan Sulfate/Chitosan Nanoparticles Loaded with an Anti-Inflammatory Peptide Increase the Response of Human Colorectal Cancer Cells to 5-Fluorouracil

    Investigators studied the capability of polyelectrolytes complex nanoparticles of dermatan sulfate and chitosan, loaded with the anti-inflammatory tripeptide IRW, to sensitize colorectal cancer cells to 5-fluorouracil.

    Abstract

    Divergent Roles of Estrogen Receptor Subtypes in Regulating Estrogen-Modulated Colonic Ion Transports and Epithelial Repair

    Researchers investigated estrogen receptor (ER) α and ERβ subtypes in the regulation of estrogen-modulated colonic epithelial HCO3− and Cl− secretion and epithelial restitution.

    Effective SARS-CoV-2 Replication of Monolayers of Intestinal Epithelial Cells Differentiated from Human Induced Pluripotent Stem Cells

    Scientists proposed utilizing monolayered-intestinal epithelial cells derived from human induced pluripotent stem cells instead of three-dimensional cultured intestinal organoids as a suitable tool to study SARS-CoV-2 infection.

    Dauricine Exhibits Anti-Inflammatory Property against Acute Ulcerative Colitis via the Regulation of NF-κB Pathway

    Researchers investigated the therapeutic effect of dauricine on ulcerative colitis. Their results indicated that dauricine attenuated the reduction of colonic length, weight loss, disease activity index, colonic tissue damage, and inflammatory cytokine levels in dextran sulfate sodium mice.

    Primary Sclerosing Cholangitis (PSC) and Inflammatory Bowel Disease (IBD): A Condition Exemplifying the Crosstalk of the Gut–Liver Axis

    Given the high risk of malignancies associated with PSC-IBD, it is critical to identify patients at high risk and implement appropriate surveillance and monitoring strategies. The authors provide an overview of PSC-IBD, which exemplifies the gut–liver axis.
