Numbers of specifically expressed protein-coding genes and circRNAs in leukemia. (A) Number of SEGs in cell lines. (B) Number of SEGs in patients. (C-D) The number of specific circRNAs in samples of (C) different leukemia subtypes and (D) cell lines. Here, SEG_high and SEG_low means the gene was highly and lowly expressed, respectively, in that subtype.
