Figure 5From: cAMP-stimulated Cl- secretion is increased by glucocorticoids and inhibited by bumetanide in semicircular canal duct epitheliumPKA activation of I sc . Summary of response of I sc to the PKA activator N6-BNZ-cAMP (n = 3) after treatment with dexamethasone in the presence of apical amiloride (10 μM). Summary data are mean ± SEM; *, P < 0.05; compared to bar prior to addition of activator. Note a break in the Y-axis.Back to article page
