TOP STORY
Anticancer Effect of Tectochrysin in Colon Cancer Cell via Suppression of NF-κB Activity and Enhancement of Death Receptor Expression
The anti-cancer effects and the molecular mechanisms of tectochrysin in colon cancer cells have not yet been reported. Scientists investigated whether tectochrysin could inhibit colon cancer cell growth at 1, 5, 10 μg/ml. [Mol Cancer] Full Article

INTESTINAL CANCERS & DISEASES

NOX1 to NOX2 Switch Deactivates AMPK and Induces Invasive Phenotype in Colon Cancer Cells through Overexpression of MMP-7
Researchers investigated the regulatory effects of membrane NADPH oxidase (NOX) and AMP activated protein kinase (AMPK) on matrix metalloproteinase (MMP)-7 expression and invasive phenotype change in colon cancer cells. [Mol Cancer] Full Article

Identification of Thiostrepton as a Novel Therapeutic Agent that Targets Human Colon Cancer Stem Cells
Scientists investigated thiostrepton’s inhibitory effects on the sphere- and colony-forming capabilities of the aforementioned colorectal cancer lines. The in vitro inhibition of sphere and colony formation was associated with downregulation of various modulators of the stem cell phenotype. [Cell Death Dis] Full Article

PHD3 Stabilizes the Tight Junction Protein Occludin and Protects Intestinal Epithelial Barrier Function
The authors showed that prolyl hydroxylase 3 (PHD3) plays a critical role in maintaining intestinal epithelial barrier function. They found that genetic ablation of Phd3 in intestinal epithelial cells led to spontaneous colitis in mice. [J Biol Chem] Abstract | Full Article

Overexpression of SULT2B1b Is an Independent Prognostic Indicator and Promotes Cell Growth and Invasion in Colorectal Carcinoma
Scientists found that sulfotransferase 2B1b (SULT2B1b) expression was frequently upregulated in colorectal carcinoma (CRC) clinical samples and CRC-derived cell lines and was significantly correlated with lymph node metastasis and TNM stage in both the training and validation cohorts. [Lab Invest] Full Article

CD103+CD11b+ Dendritic Cells Induce Th17 T Cells in Muc2-Deficient Mice with Extensively Spread Colitis
Using Muc2-/- mice, which lack a functional mucus barrier and develop spontaneous colitis, investigators showed that colitic animals have reduced colon CD103+CD11b dendritic cells and increased CD103CD11b+ phagocytes. [PLoS One] Full Article

BMP-2 Induces Motility and Invasiveness by Promoting Colon Cancer Stemness through STAT3 Activation
The authors investigated the role of bone morphogenetic protein-2 (BMP)-2 in colon cancer stem cell (CSC) development from colon cancer cells. They also determined the effects of BMP-2 on CSC development and epithelial-mesenchymal transition in human colon cancer cell lines HCT-116 and SW620. [Tumor Biol] Abstract

NECTIN-4 Increased the 5-FU Resistance in Colon Cancer Cells by Inducing the PI3K-AKT Cascade
Increased NECTIN-4 expression was observed in 5-Fluorouracil resistant (5-FU-R) and 5-FU-exposed HCT-116 cells. A significant increase in the cell proliferation, migration, colony formation, and resistant to 5-FU were noted in 5-FU-R cells, but reverse was observed after silencing of NECTIN-4. [Cancer Chemother Pharmacol] Abstract

INTESTINAL STEM CELL & ORGANOID RESEARCH

Lgr5 Positive Stem Cells Sorted from Small Intestines of Diabetic Mice Differentiate into Higher Proportion of Absorptive Cells and Paneth Cells In Vitro
The in vitro differentiation of leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) positive intestinal epithelial stem cells sorted from diabetic mice was investigated. [Dev Growth Differ] Abstract

REVIEWS
Celiac Disease and Gluten-Related Disorders in Childhood
A good diagnostic work-up is important for gluten-related disorders in childhood to avoid unnecessary restrictive diets in children. The authors provide an overview of the pathogenesis, diagnosis and management of the most common gluten-related disorders in children. [Nat Rev Gastroenterol Hepatol] Abstract
