Figure 3Effects of GTN-treatment on vascular (
a) and mitochondrial (
b) ALDH (as assessed by the conversion of benzaldehyde into benzoic acid). The substrate and product were identified and quantified by HPLC analysis. (
a) Mean ± SEM from three separate experiments (left-hand side). Right-hand side shows three representative chromatograms. Both GTN infusion (3 days) and in vitro exposure inhibits vascular ALDH. (
b) In vivo and in vitro inhibition of ALDH-2 by GTN and protection by DTT. Data are mean ± SEM from six to eight separate experiments. *
