We next assessed PPP1R13B levels in a large pan-cancer RNAseq data platform, which includes 56,938 unique samples from three well-defined datasets (TCGA/TARGET/GTEx) [13], and confirm specifically low PPP1R13B expression levels in AML when compared to 22 other tumor entities (Fig. 2A). The gene discussed is PPP1R13B; the disease is cancer.
