MOESM3 of Identification and characterization of microRNA in the lung tissue of pigs with different susceptibilities to PCV2 infection

Additional file 3. Hierarchical clustering of miRNA expression. This analysis clustered miRNA with similar patterns of expression. Each row represents a specific miRNA, and each column represents a pair of samples. That is, the color of each lattice shows the difference in the expression of a given miRNA between a pair of samples. Take LW-u vs. LW-i for example; the red indicates that the expression of a given miRNA in LW-u is higher than that of LW-i; the green indicates that the expression of a given miRNA in LW-u is lower than that of LW-i; and the grey indicates that a given miRNA is not expressed in at least one sample.
