The pattern of circRNA expression in PK-15 cells changes following SVA infection. A Heatmap showing circRNAs expressed in uninfected or SVA-infected PK-15 cells. The red line indicates high relative expression, and the blue line indicates low relative expression. B Volcano map of differential circRNAs expression between uninfected and SVA-infected PK-15 cells. The cutoff values fold change > 2 and P < 0.05 were used to identify differentially expressed circRNAs. Red represents upregulated circRNAs, green represents downregulated circRNAs, and blue represents unchanged circRNAs.
