Environmental effects of genotoxins (eco-genotoxicology) [PDF]
Genotoxic chemicals can damage the genetic material of humans as well as that of organisms living in the environment. With respect to adverse effects, alterations induced in the germ line, leading to alterations in the genetic make-up of populations, are of primary concern in ecosystems, because somatic changes, even if they lead to a loss of ...

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.

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 ...

Escherichia coli producing colibactin triggers premature and transmissible senescence in mammalian cells. [PDF]
Cellular senescence is an irreversible state of proliferation arrest evoked by a myriad of stresses including oncogene activation, telomere shortening/dysfunction and genotoxic insults. It has been associated with tumor activation, immune suppression and

Detection of DNA damage by alkaline comet assay in mouse colonic mucosa
Summary: We recently characterized the association between DNA damage and immunoresponse in vivo in colonic mucosa of mice infected with a Salmonella Typhimurium strain expressing a genotoxin, known as typhoid toxin.
