    Correction of CFTR Function in Intestinal Organoids to Guide Treatment of Cystic Fibrosis

    Intestinal organoids were grown from rectal biopsies in a cohort of 97 subjects with cystic fibrosis. Residual CFTR function was measured by quantifying organoid swelling induced by forskolin and response to modulators by quantifying organoid swelling induced by CFTR correctors, potentiator and their combination.

    Intestinal TLR9 Deficiency Exacerbates Hepatic IR Injury via Altered Intestinal Inflammation and Short‐Chain Fatty Acid Synthesis

    Mice lacking intestinal TLR9 had profoundly increased liver injury after hepatic ischemia reperfusion (IR) compared to WT mice with exacerbated hepatocyte necrosis, apoptosis, neutrophil infiltration, and inflammatory cytokine generation. They also observed increased small intestinal inflammation and apoptosis after hepatic IR in intestinal TLR9 deficient mice. Fecal short‐chain fatty acids butyrate and propionate levels were lower in intestinal TLR9 deficient mice.

    ERK/MAPK Signaling Is Essential for Intestinal Development through Wnt Pathway Modulation

    Scientists found that deletion of Erk1/2 in intestinal epithelial cells at embryonic stages resulted in an unexpected increase in cell proliferation and migration, expansion of intestinal stem cells and formation of polyp-like structures, leading to postnatal death.

    Downregulation of STK4 Promotes Colon Cancer Invasion/Migration through Blocking β‐Catenin Degradation

    Researchers found that STK4 knockdown enhanced sphere formation and metastasis in vitro and promoted tumor development in vivo. STK4 colocalized with β‐catenin and directly phosphorylated β‐catenin resulting to its degradation via the ubiquitin‐mediated pathway.

    Rock Inhibition Promotes Nav1.5 Sodium Channel-Dependent SW620 Colon Cancer Cell Invasiveness

    Y-27632 induced the acquisition of a pro-migratory cell phenotype and increased cancer cell invasiveness in both 3- and 2-dimensions assays. This effect was prevented by the inhibition of NaV1.5 voltage-gated sodium channel activity. ROCK inhibition enhanced the activity of the pro-invasive NaV1.5 channel through a pathway that was independent of gene expression regulation.

    Novel Long Noncoding RNAs Upregulation May Have Synergistic Effects on the CYP24A1 and PFDN4 Biomarker Role in Human Colorectal Cancer

    Investigators surveyed the expression levels and clinical significance of novel long noncoding RNAs related to CYP24A1 and PFDN4 genes in colorectal cancer using real‐time polymerase chain reaction. They also assessed the expression of these genes after vitamin D treatment in HCT‐116 and HT‐29 colon cancer cell lines.

    Long Non-Coding RNA MIR503HG Inhibits the Proliferation, Migration and Invasion of Colon Cancer Cells via MiR-107/Par4 Axis

    MIR503HG negatively regulated its target miR-107. MiR-107 overexpression reversed the anti-tumor effects of MIR503HG overexpression on colon cancer cells. Par4 was a target of miR-107, which was positively regulated by MIR503HG. The promoting effects of MIR503HG silencing on colon cancer cells were eliminated by Par4 overexpression.

    Berberine Inhibits Intestinal Epithelial Barrier Dysfunction in Colon Caused by Peritoneal Dialysis Fluid by Improving Cell Migration

    In the wound healing assay, berberine exhibited the ability to promote cell migration, indicating that berberine could probably recover the function of intestinal epithelial cells when the intestinal epithelial barrier was damaged by the peritoneal dialysis fluid.

    Dihydroxystilbenes Prevent Azoxymethane/Dextran Sulfate Sodium-Induced Colon Cancer by Inhibiting Colon Cytokines, a Chemokine, and Programmed Cell Death-1 in C57BL/6J Mice

    The three dihydroxystilbenes in this study inhibited colon carcinogenesis and tumor growth as well as increases in colon IL-1β, IL-6, MCP-1, and PD-1 levels in AOM/DDS-treated mice in vivo. The three dihydroxystilbenes also suppressed COX-2 expression in colon tumors in vivo and inhibited PD-1 elevations in M2-THP-1 macrophages in vitro.

    Hallmarks of Intestinal Stem Cells

    The authors summarize the recent findings into how intestinal stem cell (ISC) identity can be defined by proliferation state, signaling crosstalk, epigenetics and metabolism, and propose an update on the hallmarks of ISCs. They further discuss how these properties contribute to intestinal development and the dynamics of injury-induced regeneration.
