a Western blot of proteasome subunits expression on cell lysate from a variety of cell lines and primary MM cells, β-actin as a loading control. b Boxplot of PSME1 expression data in normal plasma cells (PC, n = 15), monoclonal gammopathy of undetermined significance (MGUS, n = 22), smoldering multiple myeloma (SMM, n = 24), newly diagnosed multiple myeloma (NDMM, n = 73), and relapsed/refractory multiple myeloma (RRMM, n = 28) from Chng et al.25. *P < 0.05, **P < 0.01, ***P < 0.001, determined using linear regression with disease stage as a factor.
