In addition, when using the Broad Institute’s Cancer Cell Line Encyclopedia (CCLE), we found that HRP2 expression was downregulated in tumor cells of hematopoietic and lymphoid tissues compared with expression in normal tissues (Supplemental Figure 1C), and was the lowest in patients with MM among all hematological cancers (Figure 1D). The gene discussed is HDGFL2; the disease is hematopoietic and lymphoid cell neoplasm.
