Bacteroides fragilis Toxin Induces Intestinal Epithelial Cell Secretion of Interleukin-8 by the E-Cadherin/β-Catenin/NF-κB Dependent Pathway

open access: yesBiomedicines, 2022
Enterotoxigenic Bacteroides fragilis (ETBF) has emerged as a gut microbiome pathogen that can promote colitis associated cancer in humans. ETBF secretes the metalloprotease, B.

Downregulation of the farnesoid X receptor promotes colorectal tumorigenesis by facilitating enterotoxigenic Bacteroides fragilis colonization

open access: yesPharmacological Research, 2022
Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer-related deaths in the world. The downregulation of farnesoid X receptor (FXR) is frequently founded in CRC patients.

Structure of the gut microbiome following colonization with human feces determines colonic tumor burden [PDF]

open access: yes, 2014
Background A growing body of evidence indicates that the gut microbiome plays a role in the development of colorectal cancer (CRC). Patients with CRC harbor gut microbiomes that are structurally distinct from those of healthy individuals;

Detection of enterotoxigenic Bacteroides fragilis in patients with ulcerative colitis

open access: yesGut Pathogens, 2017
Purpose Ulcerative colitis (UC) as a type of inflammatory bowel disease (IBD), presumed to occur as a consequence of increased immune responses to intestinal microbiota in genetically susceptible individuals.

In Vitro Evaluation of the Therapeutic Potential of Phage VA7 against Enterotoxigenic Bacteroides fragilis Infection

open access: yesViruses, 2021
Since the beginning of the 20th century, bacteriophages (phages), i.e., viruses that infect bacteria, have been used as antimicrobial agents for treating various infections. Phage preparations targeting a number of bacterial pathogens are still in use in

Enterotoxigenic Bacteroides fragilis (ETBF) strains isolated in The Netherlands and Poland are genetically diverse

open access: yesPolish Journal of Microbiology, 2004
Gram-negative anaerobic rods isolated in The Netherlands and Poland from extraintestinal and intestinal sources were identified as Bacteroides fragilis (n = 210) on the basis of Gram staining, growth on selective Bacteroides Bile Esculine medium as black colonies, and biochemical characteristics.

Lyapunov theorems for Banach spaces

open access: yes, 1993
We present a spectral mapping theorem for semigroups on any Banach space $E$. From this, we obtain a characterization of exponential dichotomy for nonautonomous differential equations for $E$-valued functions.

Bacteroides fragilis Toxin Induces Cleavage and Proteasome Degradation of E-cadherin in Human Breast Cancer Cell Lines BT-474 and MCF7

open access: yesKorean Journal of Clinical Laboratory Science, 2023
Enterotoxigenic Bacteroides fragilis (ETBF) has been reported to promote colitis and colon cancer through the secretion of B. fragilis toxin (BFT), a zinc-dependent metalloprotease. In colonic epithelial cells, BFT induces the cleavage of E-cadherin into

Integrated In Vitro, In Vivo, and In Silico Study Reveals Gut‐Protective Effects of Myricitrin From Chinese Bayberry Leaves

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
High‐purity myricitrin from Chinese bayberry leaves alleviates colonic inflammation by preserving epithelial barrier integrity and reshaping gut microbiota composition. ABSTRACT Polyphenols have been widely recognized for their ability to modulate the host inflammatory response and orchestrate the intestinal microenvironment.

Harnessing Next‐Generation 3D Cancer Models to Elucidate Tumor‐Microbiome Crosstalk

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 1, 9 January 2026.
Centralizes the microbiome within 3D tumor‐microbiome model platforms, including spheroids, organoids, 3D‐bioprinted constructs, and microfluidic chips, each enabling structured host‐tumor‐microbe studies. These systems support bacterial colonization, facilitating investigation of microbial impacts on tumor growth, immunity, and therapy. The microbiome
