Genotoxic Klebsiella pneumoniae in Taiwan. [PDF]

PLoS ONE, 2014
BACKGROUND: Colibactin is a nonribosomal peptide-polyketide synthesized by multi-enzyme complexes encoded by the pks gene cluster. Colibactin-producing Escherichia coli have been demonstrated to induce host DNA damage and promote colorectal cancer (CRC ...

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Colibactin-induced damage in bacteria is cell contact independent

mBio
The bacterial toxin colibactin, produced primarily by the B2 phylogroup of Escherichia coli, underlies some cases of colorectal cancers. Colibactin crosslinks DNA and induces genotoxic damage in both mammalian and bacterial cells.

Incidence Trends of Early‐Onset Colorectal Cancer in Germany: A Registry‐Based Study From 2003 to 2023

International Journal of Cancer, EarlyView.
The evidence on the rising incidence of colorectal cancer among adults below 50 years of age largely stems from the United States. Using high‐quality cancer registry data for the 2003–2023 period in Germany, this study found a moderate increase of early‐onset colorectal cancer incidence that was limited to those aged 20–39 years and more pronounced ...

Short-term mucosal disruption enables colibactin-producing E. coli to cause long-term perturbation of colonic homeostasis

Gut Microbes, 2023
Colibactin, a bacterial genotoxin produced by E. coli strains harboring the pks genomic island, induces cytopathic effects, such as DNA breaks, cell cycle arrest, and apoptosis.

The gut microbiome organ

iMeta, EarlyView.
The gut microbiome can be conceptualized as a distributed organ‐like functional system with spatially structured organization, broad biochemical capacity, and continuous bidirectional communication with the host. By transforming dietary, host‐derived, and environmental substrates into bioactive metabolites with endocrine‐like, immunomodulatory, and ...

Human biomarker navigator

iMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

Targeting the intratumoral microbiota to overcome cancer immunotherapy resistance

Interdisciplinary Medicine, EarlyView.
This review delineates the mechanisms of intratumoral microbiota in cancer immunotherapy resistance, and offers strategies for microbiota‐targeted precision immunotherapy. Abstract Cancer remains a significant global health threat. The tumor microenvironment (TME) is a sophisticated ecological niche that exerts a pivotal effect on treatment outcomes ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and
