What is Mercury stimulates rat liver glucocorticoid receptor association with Hsp90 and Hsp70 about?

## Abstract The subject of the present study is the influence of mercury on association of rat liver glucocorticoid receptor (GR) with heat shock proteins Hsp90 and Hsp70. The glucocorticoid receptor heterocomplexes with Hsp90 and Hsp70 were immunopurified from the liver cytosol of rats administered with different doses of mercury. The amounts of co‐immunopurified apo‐receptor, Hsp90 and Hsp70 were then determined by quantitative Western blotting. The ratio between the amount of heat shock protein Hsp90 or Hsp70 and the amount of apo‐receptor within immunopurified heterocomplexes was found to increase in response to mercury administration. On the other hand, the levels of Hsp90 and Hsp70 in hepatic cytosol remained unaltered. The finding that mercury stimulates association of the two heat shock proteins with the glucocorticoid receptor, rendering the cytosolic heat shock protein levels unchanged, suggests that mercury affects the mechanisms controlling the assembly of the receptor heterocomplexes. © 2004 Wiley Periodicals, Inc.
