Fig. 4. Seasonal changes in the ß-adrenergically stimulated RBC
Na+/H+ exchanger (ßNHE) activity (filled circles)
and ßNHE mRNA levels (relative to August value; open circles). Note one
outlying ßNHE mRNA value is plotted separately. Values are means ±
S.E.M. (N=8 for ßNHE activity values and
N=3-8 for ßNHE mRNA values). The inset shows the linear
regression curve for ßNHE activity vs ßNHE mRNA values
(P=0.038, f(x)=135.0x/(0.274+x),
r2=0.538).
