IL-22 Promotes Mucin-Type O-Glycosylation and MATH1+ Cell-Mediated Amelioration of Intestinal Inflammation
[Cell Reports] By using a range of intestinal epithelial cell type-specific conditional knockout mice and a dextran sulfate sodium colitis model, the authors demonstrated that IL-22Ra1 signaling in MATH1+ cells (goblet and progenitor cells) was essential for maintaining the mucosal barrier and intestinal tissue regeneration.
Patient Tissue-Derived FGFR4-Variant and Wild-Type Colorectal Cancer Organoid Development and Anticancer Drug Sensitivity Testing
[Heliyon] Fibroblast growth factor receptor 4 (FGFR4)-variant and wild-type colorectal cancer (CRC) organoids were developed to investigate the effects of FGFR4-targeted drugs on CRC and their possible molecular mechanism.
Metabolic Regulator ERRγ Governs Gastric Stem Cell Differentiation into Acid-Secreting Parietal Cells
[Cell Stem Cell] Using mouse models and human gastric cells, researchers identified the parietal cell progenitors arising from isthmal stem cells, and showed that they preferentially expressed cell-metabolism regulator and orphan nuclear receptor estrogen-related receptor gamma.
Protein Phosphatase 6 Activates NF-κB to Confer Sensitivity to MAPK Pathway Inhibitors in KRAS- and BRAF-Mutant Cancer Cells
[Science Signaling] To better understand the genetic pathways that modulate cancer cell sensitivity to Ras–mitogen-activated protein kinase (MAPK) pathway inhibitors, scientists performed a CRISPR knockout screen with MAPK pathway inhibitors on a colorectal cancer cell line carrying mutant KRAS.
HTRA1 Interacts with SLC7A11 to Modulate Colorectal Cancer Chemosensitivity by Inhibiting Ferroptosis
[Cell Death Discovery] HtrA serine protease 1 (HTRA1) was screened out as a colorectal cancer (CRC) progression- and chemoresistance-related gene. Gain- and loss-of-function analyses demonstrated a stimulatory role of HTRA1 on the proliferation of CRC cells.
Neutrophil-Derived PAD4 Induces Citrullination of CKMT1 Exacerbates Mucosal Inflammation in Inflammatory Bowel Disease
[Cellular & Molecular Immunology] Scientists employed single-cell RNA sequencing and substrate citrullination mapping to decipher the role of peptidyl arginine deiminase 4 (PAD4) in intestinal inflammation associated with inflammatory bowel disease.
Mitochondrial Function and Gastrointestinal Diseases
[Nature Reviews Gastroenterology & Hepatology] The authors provide an overview of the current understanding of intestinal epithelial cell mitochondrial metabolism, function and signaling to affect tissue homeostasis, in addition to mitochondrial-targeted therapeutics for inflammatory bowel diseases and colorectal cancer.
Wnt/β-Catenin Signaling, Epithelial-Mesenchymal Transition and Crosslink Signaling in Colorectal Cancer Cells
[Biomedicine & Pharmacotherapy] The authors summarize recent molecular studies on the role of the Wnt/β-catenin signaling axis in regulating epithelial-mesenchymal transition (EMT) in colorectal cancer cells, which triggers metastatic pathogenesis.
Innovent Receives NMPA Breakthrough Therapy Designation for IBI343 (Anti-Claudin18.2 ADC) as Monotherapy for Advanced Gastric Cancer
[Innovent Biologics, Inc.] Innovent Biologics, Inc. announced that the Center for Drug Evaluation of China’s National Medical Products Administration has granted Breakthrough Therapy Designation for IBI343 as monotherapy for the treatment of claudin18.2-positive advanced gastric/gastro-esophageal junction adenocarcinoma patients who have progressed after at least 2 lines of prior systematic treatments.
Cetuximab Inhibits Colorectal Cancer Development through Inactivating the Wnt/β-Catenin Pathway and Modulating PLCB3 Expression
[Scientific Reports] Scientists investigated the influence of PLCB3, a potential colorectal cancer (CRC) oncogene, on cetuximab treatment. In vitro tests revealed that cetuximab exerted a cytotoxic effect on CRC cells, with PLCB3 knockdown inhibiting CRC cell progression.
Fusobacterium nucleatum Infection Modulates the Transcriptome and Epigenome of HCT116 Colorectal Cancer Cells in an Oxygen-Dependent Manner
[Communications Biology] Using a multiomic approach, researchers analyzed epigenomic alterations of H3K27ac and global transcriptomic alterations sustained within a hypoxia and normoxia conditioned colorectal cancer cell line at 24 h following initial infection with F. nucleatum.
Circ-0075305 Hinders Gastric Cancer Stem Cells by Indirectly Disrupting TCF4–β-Catenin Complex and Downregulation of SOX9
[Communications Biology] In vitro and in vivo experiments confirmed that overexpression of Circ-0075305 could effectively reduce stem cell-like properties and enhanced the sensitivity of gastric cancer cells to Oxaliplatin compared with the control group.
Since 2015, Intestinal Cell News has been a valuable resource for keeping researchers and medical professionals updated on the latest publications, news and events in the field of gastrointestinal cell biology. Our editorial team collects and publishes the most current articles and reviews using stomach, colon, and small and large intestinal cells. We cover topics including the culturing of intestinal cells, intestinal organoids, intestinal cancers, and gastrointestinal conditions such as irritable bowel syndrome and Crohn’s disease.
