Figure 3. Clustering dendrogram of miRNAs.

MiRNAs with higher topology similarity were clustered into different modules and assigned different colors. The expression profiles of miRNAs in each module had similar structural features in the network topology. Four co-expression modules were constructed and shown in different colors. These modules were ranged from large to small by the number of genes they included. The number of miRNAs in the four modules were listed in Table 1.
