Apoptosis in myelodysplasia: a paradox or paradigm.
A growing body of evidence indicates that certain diseases are associated with increased apoptosis or inhibition of apoptosis. Among them, the myelodysplastic syndromes (MDS) are unique in that apoptosis is related, in apparently opposite directions, to the various facets of MDS. Ineffective hematopoiesis may be related to excessive intramedullary cell death via apoptosis and leukemic transformation conceivably results from escape from the apoptotic control. Future studies should be directed to define cellular susceptibility to and circumvention from apoptotic control mechanism(s).
