Growth hormone regulates intestinal ion transport through a modulation of the constitutive nitric oxide synthase-nitric oxide-cAMP pathway

Figure 1 A: Time course of the effect on short-circuit current (Isc) of GH (4 × 10^-9 mol/L) and L-NAME (2 × 10^-4 mol/L), alone or in combination, to Caco-2 cells mounted in Ussing chambers; B: Isc peak after L-NAME or GH addition, alone or in combination, to Caco-2 cells mounted in Ussing chambers. Data are mean ± SD of 6 different observations. ^aP < 0.05 GH vs L-NAME + GH.
