Mechanisms of L-Triiodothyronine-Induced Inhibition of Synaptosomal Na⁺-K⁺-ATPase Activity in Young Adult Rat Brain Cerebral Cortex

Figure 1

Inhibitory effect of various doses (0.001 nM–100 nM) of T₃ on synaptosomal Na⁺-K⁺-ATPase or Mg²⁺-ATPase activity, in vitro. The data are represented as mean ± SEM of ten separate experiments, taking six animals in each group. The vertical lines denote SEM. Filled circles indicate Na⁺-K⁺-ATPase while filled triangles indicate Mg²⁺-ATPase activity.
