HSP90AB1 and myelodysplastic syndrome with excess blasts: Again, we observed a higher expression of HSP90 (mean MFIR ± SD: 62 ± 22 versus 5 ± 6 and 25 ± 24), pAKT (51 ± 22 versus 4 ± 5 and 17 ± 22), FAK (37 ± 13 versus 4 ± 4 and 17 ± 21) and pFAK (69 ± 20 versus 4 ± 6 and 22 ± 27) in RAEB (n=93) than in RA (n=61), and CMML (n=23) respectively, CMML exhibiting intermediate levels (Figure 1).
