Arginase (Arg) I and II protein and activity levels in cardiac fibroblasts. A: Western blots of arginase I and II protein levels in CF cultured in NG (5.5 mM dextrose) or HG (25 mM dextrose) media. B: graphical representation of arginase I and II protein levels. C: arginase activity as measured by urea determinations (n = 3; *P < 0.05; **P < 0.01).
