Sodium, potassium-adenosine triphosphatase (Na+, K+-ATPase) is hypothesized to be involved in systemic vascular hypertension through its effects on smooth muscle reactivity and myocardial contractility. By means of RNA blot analyses of cardiac, aortic, and skeletal muscle RNAs in two rat hypertensive models, Na+,K+-ATPase alpha-subunit messenger RNA isoforms (alpha 2 and alpha 3) were shown to be deinduced in response to increased intravascular pressure. The changes were observed after 48 hours or more of experimental hypertension. Under these conditions, there is coordinate induction of another alpha isoform (alpha 1) and of beta-subunit messenger RNAs, probably in response to alterations in sodium flux rather than to elevated blood pressure.
