Finally, in relation to MM-MSC, although we have identified a low number of DEP, among the upregulated proteins, some of them are quite interesting and had not yet been described in the context of MM: Ras-related protein Rab-7a, among other functions, participate in cellular processes such as autophagy, apoptosis, signaling, and cell migration, being important for the progression and resistance to drugs in some types of cancer (56). This evidence concerns the gene RAB7A and Miyoshi myopathy.
