Figure 5From: Comparative expression profiles of microRNA in left and right atrial appendages from patients with rheumatic mitral valve disease exhibiting sinus rhythm or atrial fibrillation Validation of the miRNA microarray data using qRT-PCR. RNU6B was used as an internal control for normalizing the results. Data are reported as mean ± standard deviation for three independent experiments. Statistically significant differences between the two groups are indicated by *P < 0.05, compared with SR-RAA (A) or SR-LAA (B).Back to article page
