Figure 6.
Differences in microRNA-425 and microRNA-155 expression levels between black and white individuals in left atrial tissue. The microRNA-425 (Panel A) and microRNA-155 (Panel B) expression levels were normalized to the housekeeping control gene U6. The microRNA-425 and microRNA-155 expression levels in blacks (n=15) were relative to white (n=30) individuals from atrial tissues from organ donor hearts with normal ventricular function in the Myocardial Applied Genomics Network (MAGNet) repository. Data are presented as mean ± SEM. Data are presented as mean ± SEM. 2-sample t-test with Welch correction for unequal variance was used to assess the p-value by race.
