Fig. 1From: Construction and investigation of a circRNA-associated ceRNA regulatory network in Tetralogy of FallotOverview of circRNA expression profiles. a A box plot was used to compare the distributions of circRNA expression values for TOF heart tissues and normal heart tissues (control) after normalization. b Scatter-plot representing variations in circRNA expression between the TOF group and control group (log2 scaled). c Unsupervised hierarchical clustering of dysregulated circRNA expression among samples. The colour scale shows the relative expression levels of circRNAs across different samplesBack to article page
