USP7 and myelodysplastic syndrome: The analysis of the mononuclear BM cells microarray identified that UBE2T (MDS mean: 7.021 versus Control mean: 5.625; p < 0.001), UBE2O (MDS mean: 8.693 versus Control mean: 7.461; p < 0.001), and USP7 (MDS mean: 12.245 versus Control mean: 11.620; p < 0.001) were all upregulated in PMBM cells of MDS patients compared with healthy controls (Figure 1).
