title: [The Ca(2+)-pump in erythrocytes is inhibited by glucose: a possible role in the pathogenesis of chronic complications in diabetes].
abstract: An animal model in vitro condition was used in experiments, the aim of which was to test the effect of typical diabetes glucose concentration on the purified and reactivated Ca(2+)-ATPase with a defined phospholipid composition. Inhibition of Ca(2+)-ATPase activity depends on glucose concentration in a time-dependent manner. It does not depend on phospholipid content, which suggests direct glycation of the enzyme. The altered activity of erythrocyte Ca(2+)-ATPase by glycation may lead in vivo to imbalance in the ionic transport and may contribute to the development of chronic complications of diabetes.
