TOP STORY
Notch1 and Notch2 Receptors Regulate Mouse and Human Gastric Antral Epithelial Cell Homoeostasis
Investigators tested the ability of Notch pathway receptors Notch1 and Notch2 to regulate stem and epithelial cell homoeostasis in mouse and human gastric antral tissue. Notch1 and Notch2 were the predominant Notch receptors expressed in mouse and human antral tissue and organoid cultures. [Gut] Abstract

INTESTINAL CANCERS & DISEASES

Topoisomerase IIα Mediates TCF-Dependent Epithelial-Mesenchymal Transition in Colon Cancer
T-cell factor (TCF) transcription induced epithelial-mesenchymal transition (EMT), promoting a tumor-initiating cell phenotype characterized by increased proliferation, multidrug resistance, invasion and metastasis. The authors characterized topoisomerase IIα as a required component of TCF transcription promoting EMT. [Oncogene] Full Article

The Innate Immune Receptor NLRX1 Functions as a Tumor Suppressor by Reducing Colon Tumorigenesis and Key Tumor-Promoting Signals
Researchers showed that NLRX1 serves as a tumor suppressor in colitis-associated cancer and sporadic colon cancer by keeping key tumor promoting pathways in check. [Cell Rep]

DDA1 Promotes Stage IIB-IIC Colon Cancer Progression by Activating NFκB/CSN2/GSK-3β Signaling
Scientists investigated whether DDA1 contributes to tumorigenesis and progression of stage II colon cancer via activation of the NFκB pathway. [Oncotarget] Full Article

Rapid Recognition and Isolation of Live Colon Cancer Stem Cells by Using Metabolic Labeling of Azido Sugar and Magnetic Beads
Researchers recognized colon cancer stem cell (CSC) populations from colon cancer cells by using metabolic labeling of azido sugar based on the quiescent nature of these cells, which differed fundamentally from previously described methods by using specific cellular markers to recognize and isolate CSCs. [Anal Chem] Abstract

MiR-125a-5p Decreases after Long Non-Coding RNA HOTAIR Knockdown to Promote Cancer Cell Apoptosis by Releasing Caspase 2
The authors report that microRNA miR-125a-5p decreased and released caspase 2 to promote cancer cell apoptosis after HOTAIR knockdown. In 80 clinical colon cancer tissues, HOTAIR and miR-125a-5p levels were higher than adjacent tissues, whereas caspase 2 was lower. [Cell Death Dis] Full Article

GSH-Dependent Antioxidant Defense Contributes to the Acclimation of Colon Cancer Cells to Acidic Microenvironment
Investigators exposed colorectal cancer (CRC) cells to acidic pH continuously for over three months and obtained CRC cells that become acclimated to acidic pH, designated as CRC-acidosis-acclimated. [Cell Cycle] Abstract

Ulcerative Colitis-Associated Long Noncoding RNA, BC012900, Regulates Intestinal Epithelial Cell Apoptosis
Scientists aimed to determine whether long noncoding RNAs (lncRNAs) are associated with inflammatory bowel disease (IBD) and regulate epithelial cell physiology. Multiple lncRNAs are differentially expressed in IBD and play a role in regulating cellular physiology. [Inflamm Bowel Dis] Abstract

INTESTINAL STEM CELL & ORGANOID RESEARCH

Bcl-2 Is a Critical Mediator of Intestinal Transformation
Investigators found that the NF-κB target Bcl-2, an anti-apoptotic gene, is specifically expressed in intestinal stem cells (ISCs) in both mice and humans. Bcl-2 is dispensable in homeostasis and, although involved in protecting ISCs from radiation-induced damage, it is non-essential in tissue regeneration. [Nat Commun] Full Article

System-Wide Modulation of HECT E3 Ligases with Selective Ubiquitin Variant Probes
Scientists systematically developed ubiquitin variants (UbVs) that inhibit or activate HECT E3s. UbVs unearthed distinct regulation mechanisms among NEDD4 subfamily HECTs and proved useful for modulating therapeutically relevant targets of HECT E3s in cells and intestinal organoids. [Mol Cell]

REVIEWS
Intestinal Stem Cells and Intestinal Homeostasis in Health and in Inflammation: A Review
The human intestine is a complex group of organs, highly specialized in processing food and providing nutrients to the body. It is under constant threat from microbials and toxins and has therefore developed a number of protective mechanisms. One important mechanism is the constant shedding of epithelial cells into the lumen; another is the production and maintenance of a double-layered mucous boundary in which there is continuous sampling of the luminal microbiota and a persistent presence of antimicrobial enzymes.
