Fig. 5From: Upregulation of inducible NO synthase by exogenous adenosine in vascular smooth muscle cells activated by inflammatory stimuli in experimental diabetesImmunoblots for iNOS in VSMCs from control (a) and STZ-diabetic rats (b) in the presence of exogenous purines. 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 values represent the mean ± SEM (n = 5). *P < 0.05 (two-tailed t-test). PIA, N-(2-phenylisopropyl)-adenosineBack to article page
