Age-related differential small non-coding RNA (sncRNA) gene expression. (A) The categories of non-coding RNAs identified in young and old equine chondrocytes; long non-coding RNAs (lncRNAs), microRNAs (miRNAs or miRs), small nucleolar RNAs (snoRNAs), small nuclear RNAs (snRNAs), transfer RNAs (tRNAs). (B) 3D principle component analysis (PCA) plot between the selected principle components (PCs). The explained variances are shown in brackets. (C). Clustering results shown as a heatmap (distance measure using Euclidean, and clustering algorithm using Ward) for the top 90 molecules.
