Figure 2. Identification of the differentially-expressed RBPs. (A, B) The volcano plot (A) and the heatmap (B) showed that a total of 62 differentially-expressed RBPs were detected between the control and OA samples. (C) The functional annotation of the 62 genes via the Metascape database. Abbreviations: RBP: RNA-binding protein; OA: osteoarthritis.
