    UHMK1 Aids Colorectal Cancer Cell Proliferation and Chemoresistance through Augmenting IL-6/STAT3 Signaling

    Scientists demonstrated that UHMK1 was frequently upregulated in colorectal cancer samples compared with adjacent normal tissue and high expression of UHMK1 predicted poor outcomes.

    Vertical Sleeve Gastrectomy Induces Enteroendocrine Cell Differentiation of Intestinal Stem Cells through Bile Acid Signaling

    The authors hypothesized that the vertical sleeve gastrectomy-induced increase in enteroendocrine cells was due to changes in intestinal differentiation driven by an increase in bile acid signaling through farnesoid X receptor.

    MTG16 (CBFA2T3) Regulates Colonic Epithelial Differentiation, Colitis, and Tumorigenesis by Repressing E Protein Transcription Factors

    Researchers identified MTG16 as a central mediator of epithelial differentiation, promoting goblet and restraining enteroendocrine cell development in homeostasis and enabling regeneration following dextran sulfate sodium-induced colitis.

    Cardiac Glycosides Stimulate Endocytosis of GLUT1 via Intracellular Na+, K+

    The authors found that cardiac glycosides such as ouabain, oleandrin, and digoxin, which are Na+, K+-ATPase inhibitors, decreased the GLUT1 expression in the plasma membrane of human cancer cells.

    Abstract

    Regulation of Nutrient and Electrolyte Absorption in Human Organoid-Derived Intestinal Epithelial Cell Monolayers

    Investigators generated human jejunal organoid-derived monolayers to determine whether apical nutrient and electrolyte transporter function was regulated by constitutive nitric oxide in human enterocytes.

    Abstract

    SRSF9 Promotes Colorectal Cancer Progression via Stabilizing DSN1 mRNA in an m6A-Related Manner

    The expression level of serine/arginine-rich splicing factor 9 (SRSF9) was higher in colorectal cancer cell lines than that in an immortal human intestinal epithelial cell line.

    A Novel SRSF3 Inhibitor, SFI003, Exerts Anticancer Activity against Colorectal Cancer by Modulating the SRSF3/DHCR24/ROS Axis

    Scientists proposed a functional serine/arginine-rich splicing factor 3 (SRSF3) inhibitor for colorectal cancer therapy and elucidated its antitumor mechanisms.

    High Expression of miR-17-5p and miR-20a-5p Predicts Favorable Disease-Specific Survival in Stage I-III Colon Cancer

    miR-17-5p and miR-20a-5p expression was evaluated by in situ hybridization and analyzed using digital pathology. Cell line experiments, using HT-29 and CACO-2, were performed to assess the effect of miR-17-5p and miR-20a-5p.

    Visfatin Inhibits Colon Cancer Cell Apoptosis and Decreases Chemosensitivity to 5-FU by Promoting the SDF-1/CXCR4/Akt Axis

    Tissue microarrays were used to analyze visfatin differential expression in normal colon and colon cancer tissues, and the data were further validated in vitro.

    Abstract

    MiR-21 Regulates Epithelial–Mesenchymal Transition in Intestinal Fibrosis of Crohn’s Disease by Targeting PTEN/mTOR

    Tissue biopsies from fibrotic and nonfibrotic intestine of Crohn’s disease (CD)patients, and non-CD patients were obtained; chronic intestinal fibrosis model established by TNBS was treated with antagonist of miR-21; human intestinal epithelial cell, NCM460, were transfected with miR-21 mimics or inhibitor.

    Abstract

    Regulation of Apoptosis and Autophagy by Albendazole in Human Colon Adenocarcinoma Cells

    Researchers found that albendazole induced the subG1 arrest during cell cycle progression, increased the late apoptotic cells, shifted of peak TUNEL-labeled cells peak, and induced apoptosis.

    Intervention and Potential Mechanism of Non-Starch Polysaccharides from Natural Resources on Ulcerative Colitis: A Review

    Non-starch polysaccharides from natural resources, as a type of functional carbohydrates, have a significant therapeutic effect on ulcerative colitis because of their good anti-inflammatory and immunomodulatory activities.
