Microbiome and Tumor Microenvironment Interactions: Advances From Ecological Niches to Precision Oncology

open access: yesCancer Nexus, Volume 2, Issue 4, October 2026.
Tumor‐associated microbiota occupies spatially organized ecological niches and influence cancer progression by reshaping tumor‐cell signaling, metabolism, immunity, stromal remodeling, and therapeutic response. Integrating microbiome‐derived biomarkers, targeted microbial interventions, spatial multi‐omics, longitudinal monitoring, and AI may enable ...

NTBF strain NCTC 9343 outcompetes ETBF strains and secretes a growth-inhibitory protein.

open access: yes, 2016
(A) In vitro competition assay. Strain NCTC 9343 was co-cultivated with one ETBF strain and passaged after 24 h. The competitive index (CI, ratio of ETBF/NCTC 9343 DNA) was determined by strain-specific qPCR.

Gastrointestinal Pathobionts in Pediatric Crohn’s Disease Patients

open access: yesInternational Journal of Microbiology, 2018
Crohn’s disease (CD) is an inflammatory disease of the gastrointestinal tract, with a rising incidence worldwide, particularly in children. CD is thought to arise due to an immune response to environmental factors. The role of bacteria in CD has recently

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

Cancer Cell Metastasis: From Molecular Mechanisms to Therapeutic Strategies

open access: yesMedComm, Volume 7, Issue 10, October 2026.
The schematic representation of intrinsic and extrinsic influences of cancer cell metastasis. Genomic evolution of metastatic tumor cells (MTCs) promotes their metastatic phenotypes and reconstruct the primary tumor microenvironment. During MTCs migration along different routes (blood circulation, lymphatic vessels, and perineuronal spaces), the ...

ETBF strains secrete variable amounts of mature Bft.

open access: yes, 2016
Culture supernatants were obtained from ETBF strains at the indicated growth phases. The volume of each supernatant was normalized based on cell number (OD600) and proteins were concentrated 40-fold.

Repositioning small molecule drugs as allosteric inhibitors of the BFT‐3 toxin from enterotoxigenic Bacteroides fragilis [PDF]

open access: yes, 2022
Bacteroides fragilis is an abundant commensal component of the healthy human colon. However, under dysbiotic conditions, enterotoxigenic B. fragilis (ETBF) may arise and elicit diarrhea, anaerobic bacteremia, inflammatory bowel disease, and colorectal ...

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

open access: yesiMetaMed, Volume 2, Issue 3, September 2026.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

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
