Expression levels of selected miRNAs in angiotensin-(1–7)-treated or untreated A549 cells.

Relative miRNA expression in logarithmic scale by qRT-PCR corroborated the results found in miRNA PCR arrays. The graphs present values from the average from three independent experiments, and the error bars represent the standard deviation of the mean. ANOVA testing showed significant differences between the A549 untreated culture (control) and the ang-(1–7)-treated cells. The significance level was set at p<0.05 (***).
