Article Abstract
Adherent-invasive plays an important role in the pathogenesis of inflammatory bowel disease. Blocking the adhesion of to intestinal epithelial cells appears to be useful for attenuating inflammatory bowel disease. Lycopene has been reported to have anti-inflammatory and antimicrobial activities. The aim of this study was to test the intervention effect of lycopene on colitis in mice and to investigate the possible mechanism through which lycopene affects the adhesion of to intestinal epithelial cells. Lycopene (12 mg/kg BW) attenuated dextran sulfate sodium (DSS)-induced colitis, decreased the proportion of , and activated the NLR family pyrin domain containing 12 and inactivated nuclear factor kappa B pathways. Furthermore, lycopene inhibited the adhesion of O157:H7 to Caco-2 cells by blocking the interaction between O157:H7 and integrin β1. Lycopene ameliorated DSS-induced colitis by improving epithelial barrier functions and inhibiting adhesion. Overall, these results show that lycopene may be a promising component for the prevention and treatment of colitis.

Ulcerative colitis (UC) is a serious inflammatory bowel disease with a significantly increasing incidence globally. Current treatment options often exhibit unstable efficacy and notable side effects, making the exploration of alternative therapies particularly important. Peucedanum praeruptorum Dunn, a traditional Chinese medicine, contains various bioactive compounds, among which praeruptorin A (PA) has garnered attention for its anti-inflammatory potential.

Dysregulated transcription factors critically link chronic inflammation to oncogenesis in colitis-associated colorectal cancer (CAC), but their mechanistic roles remain incompletely understood. By integrating microarray and transcriptome sequencing data from ulcerative colitis (UC), colitis-associated cancer (CAC), and colorectal cancer (CRC) patients, we identify C/EBPβ as a key transcriptional regulator whose elevated expression inversely correlates with survival. In azoxymethane (AOM)/dextran sulfate sodium (DSS)-induced CAC models, intestinal epithelial C/EBPβ is upregulated during tumor progression, which is correlated with exacerbated tumor burden and neutrophil infiltration.

This study explores the extraction of polysaccharides from Nostoc commune Vauch. using ultrasonic-assisted three-phase partitioning with deep eutectic solvents (UA-TPP-DES). Response surface methodology was used to determine the optimized UA-TPP-DES conditions as follows: a 1: 2 M ratio of lauric acid to terpineol, 30 min of ultrasonication at 60 °C with 100 W power, 20 % moisture content, 20 % w/w (NH)SO concentration, and a 2: 1 top-to-bottom phase volume ratio.

The inhibitory effects of Lactiplantibacillus plantarum on inflammatory responses are known, but its action mechanisms in oxidative stress, immunomodulation, and intestinal homeostasis remain of interest. Accordingly, we investigated the protective effects of Lactiplantibacillus plantarum SCS2 (L. plantarum SCS2) against sodium dextran sulfate (DSS)-induced colitis in mice as well as elucidated its impact on inflammation, oxidative stress, and intestinal microbiota.

Background: Retinol-binding protein 4 (RBP4) is a vitamin A transport protein synthesized in the liver and also plays a crucial role in inflammation and immune regulation. Low serum vitamin A levels have been observed in both pediatric and adult patients with ulcerative colitis (UC). The association between serum vitamin A levels and serum RBP4 levels, as well as the underlying mechanism involved inimpaired vitamin A transport during inflammation in UC patients, has yet to been investigated.
