RESUMO
Neural cell adhesion molecule (NCAM/CD56) expression in acute myeloid leukemia (AML) has been associated with extramedullary leukemia, multidrug resistance, shorter remission and survival. Recently, Bloomfield et al. published a succinct review of issues surrounding the AML prognostication and current therapeutics. However, we want to reiterate the prognostic value and therapeutic potential of CD56 that is frequently expressed in AML as was also reported by their own group earlier. In addition, novel RUNX1 isoforms contribute in controlling CD56 expression in AML cells. Anti-CD56 antibody therapy deserves exploration as an arsenal against AML patients expressing CD56. Relevantly, targeting RNA splicing machinery or RUNX1 isoform-specific siRNA may also become part of future therapeutic strategies for AML with CD56 overexpression.

To assess the potential roles of protein Z (PZ) and protein Z-dependent protease inhibitor (ZPI) in venous thrombosis, their plasma levels were measured in 426 individuals with venous thrombosis and 471 control individuals participating in the Leiden Thrombophilia Study. A relationship between the level of PZ or ZPI and venous thrombosis was not detected in the overall case-control study. PZ and ZPI circulate as a complex and their plasma levels are interdependent. Both PZ and ZPI are increased with oral contraceptive use and reduced with oral anticoagulant therapy.
