FIG. 9.
Role of renal transporters in accumulation of Hg-(Cys)2 in BLM vesicles from control and NPX rat kidney(s). Net accumulation of Hg-(Cys)2 conjugate in BLM vesicles was determined by incubating vesicles with a pre-equilibrated solution of 20 μM HgCl2 and 60 μM l-cysteine, containing 203Hg2+, in the presence and absence of Na+ ions. Net accumulation values were determined as described in the legend to Figure 7. aStatistically significant difference (p < 0.05) from the corresponding sample incubated with buffer. bStatistically significant difference (p < 0.05) from the corresponding sample incubated in the absence of Na+ ions. cStatistically significant difference (p < 0.05) from the corresponding sample from BLM vesicles from control rat kidneys. ND, not determined.
