Cyst Development

Apical mislocation of the ubiquitous transport enzyme Na,K-ATPase has been implicated as a feature of cyst development in in vitro studies of human polycystic kidney disease (PKD) epithelia. We undertook an immunohistochemical study of murine glucocorticoid-induced PKD, the pcy mouse, the cpk mouse, and the diphenylthiazole (DPT)-induced rat models of PKD to determine if this feature was common to these models of cyst development. Distribution of Na,K-ATPase was determined with a polyclonal anti-Na,K-ATPase antibody and a nickel-silver-enhanced peroxidase color development system. Results were documented objectively with densitometric techniques. Control animals appropriate to the age, strain, and species of the experimental groups demonstrated the expected polar distribution of Na,K-ATPase to the basolateral surface. This distribution was more marked in mature animals. Tubular dilatation and cystic change, however, were associated with increased apical Na,K-ATPase in all models. The murine models demonstrated decreased basolateral staining for Na,K-ATPase compared with controls, although this was not a feature of the DPT rat model. Abnormal location of Na,K-ATPase is a shared feature of a variety of animal models and human PKD. This may contribute to abnormal fluid and electrolyte flux favoring cyst formation or may represent expression of a less differentiated renal tubule epithelial phenotype.

The effects of intra-arterial ethacrynic acid (EA) on vascular resistance, metabolism, and electrolyte flux was studied in the isolated denervated canine gracilis muscle perfused with a constant inflow of arterial blood. Skeletal muscle vascular resistance was markedly reduced from baseline by 25-min infusions of EA producing blood concentrations of 10−3 M but not at concentrations of 10−5 M. There were no consistent alterations in the uptake of glucose, production of lactate, or flux of potassium in the gracilis muscle during the drug infusions or 45 min postinfusion period. Venous osmolality did not change. However, the arterio venous difference for oxygen saturation across this skeletal muscle was significantly reduced by EA treatment suggesting that oxygen utilization had been inhibited. Thus, EA has a direct vasodilatory effect which is independent of measurable changes in gracilis muscle electrolyte flux or metabolism other than a possible reduction in oxygen uptake or utilization by this muscle.

1. The forearm perfusion technique was used to study the effect of intra-arterial injections of ethanol with or without digoxin on the metabolism and electrolyte flux of forearm tissues in normal male volunteers. 2. In six subjects infusion of ethanol alone (2·9 mg/min over 30 min) resulted in no alterations of forearm blood flow, O2 consumption, carbohydrate metabolism, or flux of potassium and calcium. Although there was no change in extraction of [14C]oleic acid, a significant net output of oleic and total free fatty acids was observed from both deep venous and superficial venous systems. 3. In six subjects the intra-arterial infusion of [3H]digoxin (0·09 μg/min with ethanol, 2·9 mg/min over 30 min) resulted in no alteration of forearm blood flow. During the steady state achieved after 5–8 min of perfusion, 50·3% of the calculated local arterial plasma digoxin concentration of 2·73 μg/l was extracted by the deep venous system with a significant increase in glucose extraction. The respiratory quotient and fractional utilization of O2 by glucose increased. No change in extraction of [14C]oleic acid from arterial blood was observed. However, the net output of oleic and total free acids from both deep and superficial venous systems was insignificant in comparison with that observed in the ethanol control subjects. The changes in K+ flux were similar to those noted in the ethanol group. In the post-digoxin period there was a significantly increased uptake of Ca2+ by forearm tissues. 4. This is the first demonstration of the stimulatory effects of digoxin on glucose metabolism, the antilipolytic effects of this drug and its effect on Ca2+ fluxes in vivo in man.
