Single-day and multi-day exposure to orogastric gavages do not affect intestinal barrier function in mice Universiteit Antwerpen
AIMS Animals involved in common laboratory procedures experience minor levels of stress. The direct effect of limited amounts of stress on gastrointestinal function has not been reported yet. Therefore, this study aimed to assess the effect of single-day and multi-day orogastric gavages on gut physiology in mice. MAIN METHODS Twelve-week old female C57Bl6/J mice were randomized to receive a treatment with sterile water (200 µL) delivered by ...
The orphan MRGPRF receptor is expressed in entero-endocrine cells of the human gut mucosa Universiteit Antwerpen
In the past years, it has become clear that the family of Mas-related G protein-coupled receptors plays a central role in neuro-immune communication at mucosal barrier surfaces, in particular in the skin. Remarkably, MRGPR expression at other mucosal surfaces remains poorly characterized. To fill this gap in our understanding, the present study was undertaken to screen and verify the expression of the human MRGPR family members in the mucosal ...
IL-22-activated MUC13 impacts on colonic barrier function through JAK1/STAT3, SNAI1/ZEB1 and ROCK2/MAPK signaling Universiteit Antwerpen
Overexpression of the transmembrane mucin MUC13, as seen in inflammatory bowel diseases (IBD), could potentially impact barrier function. This study aimed to explore how inflammation-induced MUC13 disrupts epithelial barrier integrity by affecting junctional protein expression in IBD, thereby also considering the involvement of MUC1. RNA sequencing and permeability assays were performed using LS513 cells transfected with MUC1 and MUC13 siRNA and ...

Epidemiological characteristics of a population visiting a patient-centered informative website about irritable bowel syndrome Universiteit Antwerpen
Background and aims: Irritable bowel syndrome (IBS) is a chronic disorder characterized by abdominal pain and an altered bowel habit. The aim of this study was to evaluate the characteristics of a population visiting a patient-centered informative website about IBS.Methods: Five digital surveys were used to assess the Rome IV criteria, red flag symptoms, healthcare use, psychological comorbidities, quality of life, symptom severity, diet, ...
Mucin-microbiome signatures shape the tumor microenvironment in gastric cancer Universiteit Antwerpen
Background and aims We aimed to identify mucin-microbiome signatures shaping the tumor microenvironment in gastric adenocarcinomas and clinical outcomes. Methods We performed high-throughput profiling of the mucin phenotypes present in 108 gastric adenocarcinomas and 20 functional dyspepsia cases using validated mucin-based RT-qPCRs with subsequent immunohistochemistry validation and correlated the data with clinical outcome parameters. The ...
Posterior compartment prolapse and perineal descent Universiteit Antwerpen
Objective: The aim of our study is to systematically review the literature about available devices facilitating perineal support during defecation in patients with obstructive defecation syndrome (ODS) and posterior pelvic organ prolapse (POP). Methods: We searched for the terms "defecat/ion or ODS" and" pessar/ies or device/aid/tool/perineal/perianal/prolapse and support" in MEDLINE, PubMed and Web of Science. Data abstraction was performed ...
Volatile organic compound profiling as a potential biomarker in irritable bowel syndrome Universiteit Antwerpen
BackgroundIrritable bowel syndrome (IBS) is a chronic gastrointestinal disorder for which no diagnostic tools are currently available. Patients are diagnosed using the Rome IV criteria and subtyped into a diarrhea, constipation, or mixed phenotype based on their dominant stool pattern. A recent development in the biomarker area is the analysis of volatile organic compounds (VOCs). The aim of this study was to evaluate the potential of VOCs as ...
Endoscopic diagnosis of a colonic localisation of a mantle cell lymphoma Universiteit Antwerpen
Extra-nodal localisations of mantle cell lymphomas are most frequently found in the gastrointestinal tract. It is therefore important for an endoscopist to be familiar with the endoscopic image of a mantle cell lymphoma. In this case series of three patients with colonic involvement of mantle cell lymphoma, we discuss the endoscopic diagnosis. (Acta gastroenterol. belg., 2022, 85, 632-634).
