Oxaliplatin resistance inevitably occurs in almost all cases of metastatic colorectal cancer (CRC), and it is important to study the roles of lncRNAs and their specific regulatory mechanisms in oxaliplatin resistance. Exosomes are increasingly designed for drug or functional nucleic acid delivery due to their properties, thereby improving the effectiveness of cancer therapy. The results of this study show that the low expression of PGM5 antisense RNA 1 (PGM5-AS1) in colon cancer is induced by transcription inhibitor, GFI1B. PGM5-AS1 prevents proliferation, migration, and acquired oxaliplatin tolerance of colon cancer cells. Exosomes encapsulating oxaliplatin and PGM5-AS1 can reverse drug resistance. For identifying differentially expressed target genes regarding PGM5-AS1, RNA transcriptome sequencing was performed. The mechanism by which PGM5-AS1 regulates its target genes was explored by performing experiments such as fluorescent in situ hybridization assay, dual-luciferase reporter gene assay, and RNA immunoprecipitation. The results show that by recruiting SRSF3, PGM5-AS1 activates alternate splicing to downregulate PAEP expression. For hsa-miR-423-5p, PGM5-AS1 can also act as a sponge to upregulate the NME1 expression.

This study investigated the protective effects of the dietary polyphenol vanillic acid (VA) on dextran sulfate sodium-induced acute ulcerative colitis (UC) in mice, focusing on its impact on the gut microbiota and inflammatory responses. VA was supplemented following dextran sulfate sodium administration, and key indicators, including body weight, disease activity index, colon length, spleen index, and inflammatory markers, were assessed. VA supplementation significantly alleviated UC symptoms, preserved intestinal barrier integrity, and reduced pro-inflammatory cytokine levels.

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC.

Background: Colorectal polyps are commonly observed in patients with chronic liver disease (CLD) and pose a significant clinical concern because of their potential for malignancy.
Aim: To explore the clinical characteristics of colorectal polyps in patients with CLD, a nomogram was established to predict the presence of adenomatous polyps (AP).
Methods: Patients with CLD who underwent colonoscopy at Tianjin Second People's Hospital from January 2020 to May 2023 were evaluated.
