We report a series of experiments designed to determine if agents and conditions that have been reported to alter sodium reabsorption, Na-K-ATPase activity or cellular structure in the rat distal nephron might also regulate the density or affinity of binding of 3H-metolazone to the putative thiazide receptor in the distal nephron. Experimental conditions selected for study were acute (60-min) and chronic hydrochlorothiazide (HCTZ), acute acetazolamide, acute and chronic furosemide, and 14 days of varied intake of dietary sodium. The density of the binding of 3H-metolazone was increased 47% by acute HCTZ (P less than 0.001) and 39% (P less than 0.001) by acute furosemide. In contrast, acute acetazolamide produced no change in binding despite eliciting a dramatic diuresis. Chronic HCTZ (5 days) and chronic furosemide (7 days) increased binding of 3H-metolazone by 46% (P less than 0.001) and by 101% (P less than 0.001), respectively. Variation of dietary sodium intake over a range that allowed normal growth of the animal and that produced urinary excretion of Na varying from 0.28 to 2.62 mEq/100 g/day failed to alter the density of binding of 3H-metolazone. These studies are the first indication that the density of the thiazide receptor is regulated by a variety of both acute and chronic conditions that have previously been associated with changes in transport, ultrastructure or Na-K-ATPase activity in the distal nephron.(ABSTRACT TRUNCATED AT 250 WORDS)
