Effect of 0.5 µM H₂O₂ on cardiac function during 30 min exposure in isolated perfused GAMT KO hearts and wild-type (WT) controls (A).

<p>GAMT KO (n = 4) with the age and sex matched corresponding wild-type (GAMT WT) mice (n = 4; female). (<b>B</b>) Effect of 0.5 µM H₂O₂ on cardiac function during 30 min exposure in isolated perfused Cr-T overexpressing (CrT-OE) hearts (n = 7; 7 female) and age matched wild-type (CrT-WT) controls (n = 4; female). RPP- rate pressure product. *P<0.05 vs WT. Data mean±S.E.M. P value is for the effect of the genotype by ANOVA with Bonferroni’s correction.
