Unsupervised hierarchical clustering (HC) using differentially expressed miRNAs. Unsupervised hierarchical clustering of 80 differentially expressed miRNAs was performed using Euclidean as distance measure and Average linkage method for linkage analysis. HC shows normal and tumor tissues as distinct clusters. 48 miRNAs were up-regulated in tumor and 32 miRNAs were down-regulated in tumor relative to normal tissues. Rows represent miRNAs and columns represent samples
