Figure 1.

Differentially expressed circRNAs in tumor tissues and adjacent nontumor tissues from gastric cancer patients. The box plot shows the variations in circRNA expression (a). The scatter plot (b) and the volcano plot (c) illustrate the distributions of the data in the circRNA profiles. The result from hierarchical clustering shows a distinguishable circRNA expression profiling among samples. The heat map shows the differentially expressed circRNAs in tumor and adjacent nontumor tissues (d). Each group consists of six samples. Gene expression profiles are shown in rows. “Red” indicates high relative expression, and “blue” indicates low relative expression.
