Immunoblots for iNOS in VSMCs from control (a) and STZ-diabetic rats (b) in the presence of adenosine turnover modulators. VSMCs were incubated as described in the legend to Fig. 1. Representative blots are shown. Densitometric analysis of iNOS protein levels are shown as  % cytomix. The data are presented as mean ± SEM (n = 8). *P < 0.05 (two-tailed t-test). NBTI, S-(4-Nitrobenzyl)-6-thioinosine; EHNA, erythro-9-(2-Hydroxy-3-nonyl)adenine; AOPCP, α,β-Methylene-ADP
