Clusters of miRNA-target genes by their correlation coefficients.

<p>The heat map representation of the correlation patterns for the miRNA targets. The 267 differentially expressed target mRNAs, including 63 up-regulated targets and 204 down-regulated targets, were used to cluster the miRNAs. Rows of the heat map represent target mRNAs, and columns represent the miRNAs. Red squares indicate negative correlations, purple squares indicate positive correlations and white spots (colorless) indicate that there is no correlation.
