To examine the toxic interactions between chromium and arsenic and determine if co-exposure to arsenic exacerbates the toxic effects of chromium.
Integrate toxicogenomic and genetic toxicology approaches using cytotoxicity and uptake assays, chromosome damage assays, comet assays and microarrays to investigate the toxic interactions of chromium and arsenic.
Arsenic potentiates the carcinogenicity of hexavalent chromium (Cr(VI)) by inhibiting the repair of chromate-induced DNA lesions leading to an increase in chromate-induced chromosomal instability and alterations in gene expression.
