Autophagy
. 2024 May;
20(10):2186-2204.
PMID: 38818900
strains producing the genotoxin colibactin, designated as CoPEC (colibactin-producing ), have emerged as an important player in the etiology of colorectal cancer (CRC). Here, we investigated the role of macroautophagy/autophagy...

PMID: 38606299
Introduction: Crohn's disease (CD) is a chronic inflammatory bowel disease, of which the etiology involves genetic, environmental and microbial factors. Adherent-invasive (AIEC) and polymorphisms in autophagy-related genes have been implicated...

Gut Microbes
. 2024 Feb;
16(1):2320291.
PMID: 38417029
Intratumoral bacteria flexibly contribute to cellular and molecular tumor heterogeneity for supporting cancer recurrence through poorly understood mechanisms. Using spatial metabolomic profiling technologies and 16SrRNA sequencing, we herein report that...

Gut Microbes
. 2024 Feb;
16(1):2310215.
PMID: 38374654
Human colorectal cancers (CRCs) are readily colonized by colibactin-producing (CoPEC). CoPEC induces DNA double-strand breaks, DNA mutations, genomic instability, and cellular senescence. Infected cells produce a senescence-associated secretory phenotype (SASP),...

Gut Microbes
. 2023 Jul;
15(1):2229569.
PMID: 37417545
Colorectal cancer (CRC) patients are frequently colonized by colibactin-producing (CoPEC) (>40%), which enhances tumorigenesis in mouse models of CRC. We observed that 50% of CoPEC also contains the gene, which...

PMID: 36670449
Background: The plasmid-mediated resistance gene mcr-1 confers colistin resistance in Escherichia coli and paves the way for the evolution to pan-drug resistance. We investigated the impact of mcr-1 in gut...

PMID: 33923277
Background: producing the genotoxin colibactin (CoPEC or colibactin-producing ) abnormally colonize the colonic mucosa of colorectal cancer (CRC) patients. We previously showed that deficiency of autophagy in intestinal epithelial cells...
