Very long O-antigen chains enhance fitness during Salmonella-induced colitis by increasing bile resistance. [PDF]

open access: yes, 2012
Intestinal inflammation changes the luminal habitat for microbes through mechanisms that have not been fully resolved. We noticed that the FepE regulator of very long O-antigen chain assembly in the enteric pathogen Salmonella enterica serotype ...

Hepatocyte Mettl3 Deficiency Drives Primary Sclerosing Cholangitis and Liver Fibrosis via Cholangiocyte‐Macrophage Crosstalk

open access: yesAdvanced Science, EarlyView.
Schematic illustration demonstrating that hepatic Mettl3 depletion significantly elevates the secretion of Mif and Csf1. This elevation facilitates Trem2+ macrophage infiltration and triggers cholangiocyte remodeling through the Spp1‐Cd44 interaction, resulting in spontaneous PSC development in vivo.

Targeting the Notch1‐YY1‐ICAM1 Signaling Axis Enhances the Efficacy of Immunotherapy in HCC by Activating CD8+ T‐Cell‐Driven Cancer Cell Pyroptosis

open access: yesAdvanced Science, EarlyView.
In hepatocellular carcinoma (HCC), aberrantly activated Notch1 signaling induces its target gene YY1, which impairs immunotherapy efficacy by suppressing tumor cell‐ICAM1‐driven T cell activation and the mediated pyroptosis of T cells against tumor cells.

The anticancer activity of bile acids in drug discovery and development

open access: yesFrontiers in Pharmacology
Bile acids (BAs) constitute essential components of cholesterol metabolites that are synthesized in the liver, stored in the gallbladder, and excreted into the intestine through the biliary system.

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

open access: yesAdvanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

The KDM6B/SLC10A2 Axis Suppresses MDSCs Recruitment via ERK/AP‐1 Signaling in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
In wild‐type intestinal epithelial cells, KDM6B demethylates SLC10A2 to promote its expression, after which SLC10A2 suppresses ERK phosphorylation, inhibiting AP‐1 (Fos/Jun) transcription and chemokine production. In KDM6B‐deficient intestinal epithelial cells, SLC10A2 methylation increases, and its expression decreases.

Autocrine Netrin‐1 Signaling in Hepatic Stellate Cells Drives Liver Fibrosis and Diet‐Induced Metabolic Dysfunction‐Associated Steatohepatitis in Mice

open access: yesAdvanced Science, EarlyView.
Netrin‐1 expression is upregulated in hepatic stellate cells (HSCs) during metabolic dysfunction–associated steatohepatitis and injury‐mediated liver fibrosis. Secreted Netrin‐1 establishes an autocrine positive feedback loop by binding to UNC5B receptors on HSCs.

Systematic identification of secondary bile acid production genes in global microbiome

open access: yesmSystems
Microbial metabolism of bile acids (BAs) is crucial for maintaining homeostasis in vertebrate hosts and environments. Although certain organisms involved in bile acid metabolism have been identified, a global, comprehensive elucidation of the microbes ...
