Evaluation of Clastogenic/Aneugenic Damage Using the FISH Micronucleus Assay in Mice Exposed to Chromium (VI).

Background/aim: Exposure to chromium (VI) [Cr(VI)] has been postulated to be associated with the induction of cancer. In vivo studies utilizing biomarkers of genotoxic damage could aid in elucidating the mechanisms underlying the genotoxic effects of Cr(VI) and their relationship with carcinogenesis. In this study, the origin (clastogenic and/or aneugenic damage) and kinetics of micronuclei (MN) induced by Cr(VI) were investigated.
