Figure 4: NOS3 mRNA expression (ng-equ) in left ventricle myocardium measured in controls (controls), pathological samples with non-detectable MMP-3 mRNA expression (N-MMP3) and pathological samples with detectable MMP-3 mRNA expression (MMP3) (A). NOS1 mRNA expression (ng-equ) in the same samples as in A (B). *p < 0.05 versus controls, **p < 0.01 versus controls.
