Impact of arsenite and its methylated metabolites on PARP-1 activity, PARP-1 gene expression and poly(ADP-ribosyl)ation in cultured human cells.
The underlying mechanisms of arsenic carcinogenicity are still not fully understood. Mechanisms currently discussed include the induction of oxidative DNA damage and the interference with DNA repair pathways. Still unclear is the role of biomethylation, which has long been considered to be one major...
