PIM2 and AL amyloidosis: Additional analysis of datasets GSE6691, GSE47552, and GSE9656, as well as single‐cell sequencing data GSE193531 (see Supporting Information), demonstrated that the expression levels of PIM‐2 (Figure 1B) and PARP1 (Figure 1E) were significantly elevated in multiple myeloma (MM) compared to normal bone marrow and monoclonal gammopathy of undetermined significance (MGUS), suggesting that both proteins are integral to the pathogenesis and progression of multiple myeloma.
