Environmental effects of genotoxins (eco-genotoxicology) [PDF]

open access: yesMutagenesis, 1992
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]

open access: yesMutation Research/Genetic Toxicology and Environmental Mutagenesis, 2021
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.

Cytogenetic Studies on Genoprotective Effect of Rosa damascena Mill. Hydrosol in Plant and Lymphocyte Test Systems

open access: yesLife, 2023
Bulgarian Rosa damascena Mill. is has been known since ancient times for its high-quality oil, hydrosol, and other aromatic products. Rose hydrosol has various biological activities, but no research on its anticytotoxic/antigenotoxic effects exists. This

Escherichia coli producing colibactin triggers premature and transmissible senescence in mammalian cells. [PDF]

open access: yesPLoS ONE, 2013
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

Bacterial Toxin Modulation of the Eukaryotic Cell Cycle: Are all Cytolethal Distending Toxins Created Equally?

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
The cytolethal distending toxins (CDTs) comprise a family of intracellular-acting bacterial protein toxins whose actions upon eukaryotic cells result in several consequences, the most characteristic of which is the induction of G2/M cell cycle arrest ...
