    Tissue Geometry Drives Deterministic Organoid Patterning

    Scientists developed approaches for specifying the initial organoid geometry to build intestinal organoids of defined shape, size, and cell distributions, forming structures that were predictable, more similar to normal organs, and reproducible.

    Human Gut-Microbiome-Derived Propionate Coordinates Proteasomal Degradation via HECTD2 Upregulation to Target EHMT2 in Colorectal Cancer

    Researchers showed that propionate suppressed colorectal cancer growth by promoting the proteasomal degradation of euchromatic histone-lysine N-methyltransferase 2 (EHMT2) through HECT domain E3 ubiquitin protein ligase 2 (HECTD2) upregulation.

    Functional Assessment of miR-1291 in Colon Cancer Cells

    The expression and effect of miR‑1291 in colorectal cancer cells (CRC) was investigated. It was identified that miR‑1291 significantly suppressed the proliferation, invasion, cell mobility and colony formation of CRC cells.

    Abstract

    Ginkgo biloba Extract Inhibited Cell Proliferation and Invasion by Stimulating TET2 Expression through miR-29a in Colorectal Carcinoma Cells

    Scientists analyzed the effects of Ginkgo biloba extract (GBE) administration on TET2 expression in human colorectal cancer (CRC). To investigate the expression profiles of TET2, GBE was used to treat CRC cells.

    Abstract

    BIX-01294 Enhances the Effect of Chemotherapy on Colorectal Cancer by Inhibiting the Expression of Stemness Genes

    A small molecule EHMT-2 inhibitor, BIX-01294, was evaluated for its activity in inhibiting cancer stem cells in human colorectal cancer by in vitro and in vivo experiments.

    Abstract

    Intestinal Epithelial Damage Due to Herbal Compounds – an In Vitro Study

    To determine whether certain herbal preparations containing coumarin might cause damage to the intestinal epithelium, Caco2 cells were exposed to common phytochemicals. Coumarin, astragaloside IV or atractylenolide I solutions were exposed to Caco2 cultures in increasing concentrations, individually or combined.
