Fig. 1

CircRNA microarray expression data between the KYSE-150 and KYSE-150R cells. a Hierarchical clustering shows a distinguishable circRNA expression profiling among KYSE-150 and KYSE-150R cell. b Box plots show the distribution of circRNAs for the two compared samples. The distributions were nearly the same after normalization. c Scatter plots assess the circRNA expression variation between the two compared groups. The circRNAs above the top green line and below the bottom green line indicated more than twofold changes of circRNAs between the two compared samples
