    Cell-Intrinsic Aryl Hydrocarbon Receptor Signaling Is Required for the Resolution of Injury-Induced Colonic Stem Cells

    Investigators showed that the aryl hydrocarbon receptor was important for the termination of the regenerative response and the reacquisition of mature epithelial cell identity post-injury in vivo and in organoid cultures in vitro.

    Aurora Kinase a Inhibition Induces Synthetic Lethality in SMAD4-Deficient Colorectal Cancer Cells via Spindle Assembly Checkpoint Activation

    Scientists performed a synthetic lethal drug screening with SMAD4-isogenic colorectal cancer cells and found that aurora kinase A inhibition was synthetic lethal with SMAD4 loss.

    Abstract

    KLF5 Inhibition Overcomes Oxaliplatin Resistance in Patient-Derived Colorectal Cancer Organoids by Restoring Apoptotic Response

    Researchers constructed colorectal cancer PDOs and selected the Kruppel-like factor 5 (KLF5) inhibitor ML264 as the research object based on the results of an in vitro drug screening assay.

    Acquisition of NOTCH Dependence Is a Hallmark of Human Intestinal Stem Cell Maturation

    Using single-cell transcriptomics, investigators observed that OLFM4, a NOTCH target gene present in intestinal stem cells, was first expressed at 13 weeks post-conception in the developing human intestine and increased over time.

    Gastric Cancer Cell-Derived Extracellular Vesicles Elevate E2F7 Expression and Activate the MAPK/ERK Signaling to Promote Peritoneal Metastasis through the Delivery of SNHG12

    Scientists explored the ability of gastric cancer (GC) cell-derived extracellular vesicles-mediated microRNA-129-5p/E2F transcription factor 7/mitogen-activated protein kinase/extracellular regulated protein kinase (MAPK/ERK) axis to affect the peritoneal metastasis of GC by delivering lncRNA small nucleolar RNA host gene 12 (SNHG12).

    ZIC2 Promotes Colorectal Cancer Growth and Metastasis through the TGF-β Signaling Pathway

    The authors found that high ZIC2 expression was not only associated with poor prognosis, relapse-free survival and advanced metastasis but was also an independent prognostic factor in colorectal cancer patients.

    Abstract

    Glyphosate-Based Herbicides Induces Autophagy in IPEC-J2 Cells and the Intervention of N-Acetylcysteine

    Researchers investigated the effects of glyphosate-based herbicides on antioxidant capacity, inflammatory cytokines, and autophagy of porcine intestinal epithelial cells (IPEC-J2) and its molecular mechanism.

    Abstract

    Downregulation of MiR-1538 Promotes Proliferation and Metastasis of Colorectal Cancer by Targeting DNMT3A

    Scientists found that the expression of miR-1538 was significantly down-regulated in colorectal cancer tissues and cells, and its expression level was significantly correlated with tumor size, clinical stage and prognosis.

    Abstract

    Heme Oxygenase-1 & 2 and Their Potential Contribution in Heme Induced Colorectal Carcinogenesis

    Researchers investigated the role of heme in heme oxygenase-1 (HO-1) and HO-2 induced colorectal carcinogenesis and the clinicopathological significance of their expressions in patients with colorectal carcinoma.
