Fig. 4From: Vascular Gene Transfer of the Human Inducible Nitric Oxide Synthase: Characterization of Activity and Effects on Myointimal Hyperplasia Comparison of \({\bf{NO}}_2^ - \) production by uninfected SPAEC, SPAEC-BaglacZ, and SPAEC-DFGiNOS Each bar represents the mean ± SD (n = 3 for each group, experiments were repeated three or more times with comparable results). L-NMA was added at 0.5 mM concentrations, while BH4 was supplemented at 100 µM. *p < 0.01 versus uninfected ±L-NMA, ±BH4 and BaglacZ ±L-NMA, ±BH4 by ANOVA.Back to article page
