    ESRP1-Regulated Isoform Switching of LRRFIP2 Determines Metastasis of Gastric Cancer

    Investigators presented that epithelial and mesenchymal isoform switches of leucine-rich repeat Fli-I-interacting protein 2 (LRRFIP2) regulated by epithelial splicing regulatory protein 1 (ESRP1) correlated with the metastatic potential of gastric cancer cells.

    Intestinal Apc-Inactivation Induces HSP25 Dependency

    In order to investigate the role of molecular chaperones in driving colorectal cancer initiation, scientists captured the transcriptomic profiles of murine wild type and Apc-mutant organoids during active transformation.

    Myosin Vb as a Tumor Suppressor Gene in Intestinal Cancer

    Investigators found that the loss of Myosin Vb interfered with the differentiation/polarization of colorectal cancer cells. Although modulation of Myosin Vb expression did not affect the proliferation of colon cancer cells, MYO5B inactivation increased their migration, invasion, and metastatic potential.

    Abstract

    Plakophilin 2 Regulates Intestinal Barrier Function by Modulating Protein Kinase C Activity In Vitro

    Researchers characterized the presence of desmosomal plaque proteins plakophilins (PKPs) in the human intestine and in different in vitro models to assess the basic contribution of PKPs in the context of intestinal epithelial barrier regulation.

    Rewiring Glucose Metabolism Improves 5-FU Efficacy in p53-Deficient/KRASG12D Glycolytic Colorectal Tumors

    Scientists analyzed the 5-fluorouracil (FU) response in patient-derived organoids that reproduced the different stages of colorectal cancer and found that 5-FU induced pyrimidine imbalance, which led to DNA damage and cell death in the actively proliferating cancer cells deficient in p53.

    Abstract

    Butyrate Reduces Cellular Magnesium Absorption Independently of Metabolic Regulation in Caco-2 Human Colon Cells

    Researchers investigated the physiological role of short-chain fatty acids (SCFAs) on intestinal Mg2+ by elucidating the molecular mechanisms by which SCFAs modulate Mg2+ uptake in the human colon cell line Caco-2.
