Hormonal Effects on the Expression of Na+/K+-ATPase Beta Subunit During Pregnancy
The Na+/K+-ATPase in several tissues is not homogeneous but contains catalytic subunits varying in structure as well as in function (6). The ratio of these isoenzymes is altered during development and influenced also by hormonal levels (5,3). In our previous work we demonstrated the presence of two different kind of isozymes in rat myometrium and one of them showed an increased Ca sensitivity (8).
