PCA, Valcano and Heatmap analyses of circRNA expression profiles. a MM patients and HCs were divided into two different groups by circRNAs. b 122 circRNAs were upregulated and 260 circRNAs were downregulated in MM compared with HCs. c The differentially expressed circRNAs were able to differentiate MM patients from HCs. MM, multiple myeloma; circRNAs, circular RNAs; HCs, healthy controls
