Validation of RNA abundance. Correspondence in RNA levels between current PRAX1 study and prior microarray analyses of RNA.26,27 (A) and (B) show rank correlations for mRNAs (Spearman coefficient = 0.55, P = 4.3 × 10−260) and miRNAs (Spearman coefficient = 0.72, P = 1.8 × 10−23), respectively. The black line represents the Deming regression line.
