To determine if MYP3 cells metabolize arsenicals, cells were treated with arsenate, arsenite and MMA (V) as described above and the medium was analyzed by HPLC-ICPMS to determine species and quantity of arsenicals present.

In this study, we investigated the growth effects of As (III) and an organic trivalent arsenical, dimethylarsinous acid (DMA (III)), and the effects of co-exposure of gefitinib, an EGFR inhibitor, with As (III) to a rat urothelial cell line (MYP3).

Using rat (MYP3) and human (1T1) urothelial cells, cytotoxicity for trivalent arsenicals, sodium arsenite, monomethylarsonous acid (MMA (III)), and DMA (III) was demonstrated at 0.4-4.8 microM concentrations, whereas MMA (V), DMA (V), and TMAO were cytotoxic at millimolar concentrations.
