NPM1 and Miyoshi myopathy: In MM-PC and ND-PC comparisons, among upregulated proteins involved in protein biosynthesis, NPM1 deserves attention, since its upregulation was also found in MM patients with hyperdiploidy [21,22] and Maggi et al. (2008) [23] demonstrated in other cell types that NPM1 upregulation enhances protein biosynthesis and the export of newly synthesized rRNAs.
