Figure 4. Comparison of myocardial APJ receptor mRNA for samples collected from patients shown in Table 3 then re-perfused at 2, 20 or 60% O₂ for 4 h.

The same patients as for Table 3 were use but split into 2 groups (cyanotic and acyanotic). Expression was calculated using the Comparative Ct method to give RQ of gene expression using the StepOne Software v2.1). Statistical analysis was performed using the Mann-Whitney U test. Data shown as box and whiskers plot.
