We now report that the retroviral vector-mediated overexpression of MRP1 and of the two subunits of gamma-GCS (heavy and light) resulted in higher intracellular glutathione levels and in a greater level of resistance to sodium arsenite and antimony potassium tartrate, compared to the overexpression of MRP1 and gamma-GCS heavy alone.

In contrast, resistance to sodium arsenite was only partially diminished, and resistance to potassium antimony tartrate remained comparable to that of cells expressing wild-type MRP1.

We therefore compared expression of the multidrug resistance-associated proteins MRP1, MRP2, and MRP3 in these two cell lines.

The accumulation of [(14) C] carboplatin and [(3) H] methotrexate is reduced in single-step KB epidermoid adenocarcinoma (KB-CP) cells, which are cross-resistant to carboplatin, methotrexate, and sodium arsenite.
In these KB-CP cells, multidrug resistance is accompanied by mislocalization of multidrug resistance associated protein (MRP) 1 and other membrane proteins such as folate-binding protein.

Following administration of sodium arsenite to these mice, approximately 60-70% of urinary arsenic is present as one of these GSH conjugates.
Rodents deficient in three known ABC family transporters (MRP1, MRP2, and MDR1a/1b) exhibited urinary arsenic levels similar or greater than those in wild-type rodents; however, administration of MK571, an MRP inhibitor, reduced urinary arsenic excretion by almost 50%.

Our results indicate that this tolerance in human cells involves increases in GSH levels and GST activity that allow for more efficient arsenic efflux by MRP1 and MDR1.
RWPE-1 cells continuously exposed to 5 microM sodium arsenite for > or =18 weeks exhibited dramatic resistance to acute arsenite toxicity.

To clarify the pathophysiological mechanism underlying acute renal injury caused by acute exposure to arsenic, we subcutaneously injected both BALB/c and C57BL/6 mice with sodium arsenite (NaAs; 13.5 mg/kg).

KAS cells were resistant to sodium arsenite (22-fold) and showed a reduced accumulation of arsenite as a result of an active efflux mechanism.
