Abstract

The Na+, K+-ATPase activity and its response to vanadate inhibition was investigated in cerebral cortex homogenates of 7-, 12- and 18-day-old rats. The enzyme was inhibited by vanadate in a dose-dependent manner in all these age groups. Furthermore, there was a different sensitivity towards vanadate during postnatal development; the concentration of V+5 needed for 50% inhibiton of Na+, K+-ATPase was 1.1×10−6M, 2×10−7M and 4.4×10−7M for 7-, 12- and 18-day-old rats, respectively. It is suggested that the different sensitivity of Na+, K+-ATPase towards vanadate inhibition during postnatal development might be due to age-dependent changes in the ratio of various cell types.
