Figure 4. Differential effect of the KATP channel opener cromakalim to inhibit the smRLC phosphorylation response to activation of α2- and α1-adrenoceptors.
Cromakalim inhibited the increases in smRLC phosphorylation induced by UK 14,304 (20 μm), but not by phenylephrine (10 μm). Results were similar for soleus and EDL muscles. *P < 0.05 versus no drug; n≥ 4 muscles per treatment.
