Scatter plot of miRNA expression by miRNA microarray analysis. The expression profile of 346 miRNAs as log10 (2^-Delta Ct) in PCOS (DHT) and in control group (CTL) is plotted. Specific miRNA expression positioned on the mid-line indicates no differential expression. Whereas lines above or under the mid line denotes the boundary of 2 fold regulation of miRNA expression. Red and green circles represent the number of miRNAs in DHT ovary significantly (P < 0.05 and 2 fold-change cut off) over-expressed and down-regulated, respectively.
