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

Advanced 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

Smoking and nicotine in inflammatory bowel disease: good or bad for cytokines?

Mediators of Inflammation, 1998
Smoking has either a beneficial or harmful effect on the course and recurrence of ulcerative colitis and Crohn's disease respectively. Transdermal application of nicotine had similar effects in ulcerative colitis and therefore was considered to be an ...

A20 Facilitates Oxaliplatin Sensitivity in Colorectal Cancer Through Monoubiquitylation of IKK‐β

Advanced Science, EarlyView.
This study demonstrates that the expression of A20, a ubiquitin‐editing enzyme, is positively correlated with oxaliplatin sensitivity in colorectal cancer (CRC). Mechanistically, A20 enhances oxaliplatin sensitivity by inhibiting NF‐κB nuclear translocation through monoubiquitination of IKK‐β.

Tobacco Smoke Exposure From Prenatal To Adolescent Periods Drives IBD Pathogenesis: Dynamic DNA Methylation Signatures Across Lifespan Stages

Advanced Science, EarlyView.
This study illustrates that maternal smoking during pregnancy (MSDP) is an independent risk factor for IBD in offspring, and DNA methylation serves as a key mechanistic pathway connecting early‐life smoking exposure with IBD risk in offspring. That highlights the urgent need for preventive interventions targeting prospective parents and minors to ...

DR5 Governs Compound Exocytosis in Colonic Goblet Cells via TATA‐Box Binding Protein‐Dependent Bestrophin‐2 Transcriptional Regulation

Advanced Science, EarlyView.
DR5 knockout exhibits a thinner colonic mucus layer, leading to mild dysbiosis, increased susceptibility to Citrobacter rodentium invasion, and exacerbated epithelial injury. Mechanistically, DR5 binds transcription factor TBP, which regulates the expression of gene Best2 via its promoter.

Phocaeicola coprophilus‐Derived 6‐Methyluracil Attenuates Radiation‐Induced Intestinal Fibrosis by Suppressing the IDO1‐Kynurenine‐AHR Axis

Advanced Science, EarlyView.
IR‐induced dysbiosis depletes P. coprophilus and its metabolite 6‐methyluracil, leading to disinhibition of the IDO1‐Kyn‐AHR axis. This results in sustained fibroblast activation and collagen deposition, driving radiation induced intestinal fibrosis. ABSTRACT Therapeutic options for radiation‐induced intestinal fibrosis (RIF) remain limited. This study
