Fusobacterium nucleatum in cancer: Interactions with microbiota, tumour colonisation and cancer progression

Clinical and Translational Medicine, Volume 16, Issue 6, June 2026.
F. nucleatum colonises tumours through mucosal translocation, adjacent‐tissue migration and hematogenous dissemination. It promotes cancer progression via adhesion, inflammation, immune evasion, epigenetic remodelling and metastasis. Its effects on therapy response are tumour‐context dependent. Microbiome‐guided targeting may enable precision oncology.

Association of a Novel Dietary Index Assessing Gut Microbiota Impact With Rheumatoid Arthritis: A Nationwide Population‐Based Study

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
This graphical abstract illustrates a cross‐sectional study of 29,656 U.S. adults from NHANES 2007–2020, examining the association between the Dietary Index for Gut Microbiota (DI‐GM) and rheumatoid arthritis (RA). Higher DI‐GM scores (reflecting beneficial foods for gut microbiota) were linearly associated with lower RA prevalence.

Extracellular Vesicles of Giardia duodenalis: Unravelling Their Virulence Factors and Potential to Induce Protection Against Experimental Giardiasis

Journal of Extracellular Biology, Volume 5, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) are key mediators of intercellular communication, enabling trans‐kingdom exchange of proteins, nucleic acids, lipids, and metabolites. In Giardia duodenalis, EVs contribute to parasite survival, host–pathogen interactions, and immune modulation.

Fecal Microbiome Alterations in Colorectal Cancer: A Systematic Review of Compositional Changes and Microbial Biomarkers

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Gut microbiome plays a crucial role in colorectal cancer development. The advanced sequencing techniques have the potential to complement current non‐invasive methods for early diagnosis and prevention of colorectal cancer. This includes conducting studies with robust statistical power and consistent, replicable methodologies, taking into consideration
