miRNA-mRNA correlation network. miRNA-mRNA correlation network discovered by SA-BNs, rendered in cytoscape . In this network, the miRNAs are demonstrated by diamond shape while mRNAs with circles. Upregulated miRNA are in red, while downregulated miRNA are in green. Upregulated mRNAs are in pink, while downregulated are in light green. The positive correlated miRNAs and mRNAs are connected by red line, while the negative correlations by blue lines.
