CONCLUSION: Sodium arsenite can induce expression of MRP2 and the up-regulation of MRP2 may play an important role in the bile secretion of arsenite and its metabolites.

Exposure of fish to arsenic as sodium arsenite (4-14 days) increased both MRP2 expression in the apical membrane of proximal tubules and MRP2-mediated transport activity.

METHODS: Thirty healthy Wistar rats were divided randomly into six groups based on time of administration (2 w, 4 w, 6 w) of 20 mg/kg of sodium arsenite, and their corresponding control groups.

Treatment of primary rat hepatocytes by sodium arsenite [As (III)], sodium arsenate and potassium antimony tartrate, but not cadmium chloride, was shown to markedly increase MRP2 mRNA and protein levels; As (III)-mediated induction was dose- and time-dependent and paralleled a strong increase in MRP2 amounts as assessed by Western blotting.

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%.
