Nissle 1917 is sold as a probiotic and considered safe even though it has been known since 2006 that it harbors the genes for colibactin synthesis. Colibactin is a potent genotoxin that is now linked to causative mutations found in human colorectal ...

The genotoxin colibactin is produced by several species of Enterobacteriaceae. This genotoxin induces DNA damage, cell cycle arrest, senescence and death in eukaryotic cells (Nougayrède et al., 2006; Taieb et al., 2016).

Cellular Senescence Triggered by Food and Environmental Genotoxins. [PDF]
Cellular senescence (CSEN) is caused by a variety of factors that trigger complex molecular pathways. These include telomere shortening, oncogene activation and replicative stress, as well as DNA damage caused by genotoxic anticancer drugs and endogenous and exogenous genotoxins.

Functional and Structural Characterization of Chimeras of a Bacterial Genotoxin and Human Type I DNAse [PDF]
Chimeras composed of the cdtB gene of a novel bacterial genotoxin and the human type I DNAse I gene were constructed and their products characterized relative to the biochemical and enzymatic properties of the native proteins. The product of a cdtB/DNAse

Soritesidine, a Novel Proteinous Toxin from the Okinawan Marine Sponge Spongosorites sp.
A novel protein, soritesidine (SOR) with potent toxicity was isolated from the marine sponge Spongosorites sp. SOR exhibited wide range of toxicities over various organisms and cells including brine shrimp (Artemia salina) larvae, sea hare (Aplysia ...

CYP1B1 converts procarcinogens into genotoxins in Saccharomyces cerevisiae [PDF]
ABSTRACT CYP1B1 activates many chemical carcinogens into potent genotoxins, and allelic variants are risk factors in lung, breast, and prostate cancer. However, genetic instability phenotypes incurred by CYP1B1-activated metabolites have been investigated for only few compounds.

Bacterial genotoxins induce T cell senescence
Several types of pathogenic bacteria produce genotoxins that induce DNA damage in host cells. Accumulating evidence suggests that a central function of these genotoxins is to dysregulate the host's immune response, but the underlying mechanisms remain unclear.
