Characterizations in circRNA expression patterns of SACC and matched normal tissues. a The difference in the expression of circRNAs in SACC and matched normal tissues was shown by scattered plot. b Volcano plot shows the differential expression of circRNA between the two groups. The red dots indicated the up-regulated circRNAs, the blue dots indicated the down-regulated circRNAs. c The type of differentially expressed circRNAs. d The distribution of all circRNAs and the differentially expressed circRNAs in human chromosomes
