Specificities of circRNAs expression in T-ALL subgroups. (A) Expression profiles of the 75 circRNAs upregulated in at least 1 T-ALL group (DESeq adjusted P < .01; standardized expression values and per row log average expression are shown in the heatmap and in the bar on the right, respectively). (B) Venn diagram of circRNAs upregulated in each T-ALL subgroup overlap defines the circRNAs upregulated with group specificity; tables indicate circRNAs with average expression in the group >10 showing in larger characters those with expression >30.
