Busulfan 16 mg/kg and cyclophosphamide 120 mg/kg were used as conditioning prior to allogeneic marrow transplantation in 50 adult patients with acute nonlymphocytic leukemia (ANLL), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML). A standard risk group of 20 patients included those with acute leukemia in remission and CML in chronic phase. A high-risk group of 30 patien...
To evaluate the role of the deleted in colorectal carcinoma (DCC) gene in leukemogenesis, we examined loss of heterozygosity (LOH) in the DCC gene in 64 primary human leukemias using Southern blot analysis and examined the expression of the DCC gene using reverse transcriptase-polymerase chain reaction (RT-PCR) analysis. Allelic loss in the DCC gene was observed in two patients (6%, 2 of 35 inf...
By Janet D. Rowley I N 1951, Dameshek’ coined the term “myeloproliferative syndromes” to identify a group of hematologic disorders characterized by proliferation of one or more of the cell types that occur in the bone marrow. This concept provided a unifying hypothesis which has proved useful in the analysis of the similarities and differences between the various disorders. A particularly valua...
Defining the role of epigenetic regulators in hematopoiesis has become critically important, because recurrent mutations or aberrant expression of these genes has been identified in both myeloid and lymphoid hematological malignancies. We found that PRMT4, a type I arginine methyltransferase whose function in normal and malignant hematopoiesis is unknown, is overexpressed in acute myelogenous l...
Natural killer cell activity was evaluated in children with acute lymphocytic and acute myelogenous leukemia. Peripheral blood mononuclear cells isolated at the time of diagnosis and before initiation of therapy were mixed with 51Cr-labeled K562 or MOLT-4 target cells at a ratio of 100:1. In 13 consecutive cases of acute lymphocytic leukemia, the mean percentage of lysis of K562 cells (15.0%) w...
