Figure 4. Pendrin gene ablation does not affect nitric oxide-dependent smooth muscle relaxation.

Aortic rings from wild type and pendrin null mice were preconstricted with 30 nM phenylephrine. Relaxation in response to sodium nitroprusside (SNP, 0.1 to 300 nM)) was then determined. Data are expressed as the percent relaxation in response to the incremental addition of SNP (n = 5).
