By THOMAS J. LYNCH AND WILLIAM C. MOLONEY D URING STUDIES on the induction of myelogenous leukemia in the rat, serum B12 afl(I folate activities were investigated. In man it is well known tiiat serum B1 activity is greatly elevated in chronic myelogenous leukemia ( CML ) . Less is known concerning serum folate activity hut from iiiitial reports and in our own experience, serum folate levels are...
A reciprocal translocation involving the short arms of chromosomes 7 and 11, t(7;11)(p15;p15), was found in nine patients including eight with acute myelogenous leukemia (AML) and one with Philadelphia (Ph1) chromosome-positive chronic myelogenous leukemia (CML) in blastic crisis. Although a similar chromosome rearrangement has previously been reported in five patients, including three with AML...
In chronic myelogenous leukemia (CML) and in a percentage of childhood and adult acute lymphoblastic leukemia (ALL) the Philadelphia (Ph’) chromosome is present in the leukemic cells of patients. This chromosome is the result of a reciprocal translocation between chromosomes 9 and 22. In CML the break on chromosome 22 occurs within the major breakpoint cluster region (Mbcr) of the bcr gene. In ...
Pyrrolo[1,2-b][1,2,5]benzothiadiazepine 5,5-dioxides (PBTDs) induced apoptosis in human BCR-ABL-expressing leukemia cells. The apoptotic activity was also observed in primary leukemic blasts, obtained from chronic myelogenous leukemia (CML) patients at onset or from patients in blast crisis and who were imatinib-resistant. Compounds 5 and 14 induced apoptosis before BCR-ABL protein expression a...
Eight patients with Ph1-positive chronic myelogenous leukemia (CML) in chronic or accelerated phase received high-dose cyclophosphamide, total body irradiation, and bone marrow transplantation from an HLA-identical sibling donor. All patients had prompt engraftment and achieved complete hematologic remission. Six patients remain alive and in continuous remission with a normal bone marrow karyot...
The bcr-abl oncogene plays a critical role in causing chronic myelogenous leukemia (CML). Effective laboratory animal models of CML are needed to study the molecular mechanisms by which the bcr-abl oncogene acts in the disease progression of CML. We used a murine stem cell retroviral vector (MSCV) to transduce the bcr-abl/p210 oncogene into mouse bone marrow cells and found that expression of B...
Chronic myelogenous leukemia (CML) is a clonal proliferative disease originating from a pluripotential stem cell in which a 9:22 translocation, Philadelphia (Ph) chromosome, results in the production of BCR-ABL fusion protein that has constitutive tyrosine kinase activity and deregulates signal transduction pathways, thus causing leukemia. The natural course of CML is usually triphasic (chronic...
Three patients had marked marrow fibrosis and an apparent Philadelphia (Ph) chromosome. Hematologic, cytogenetic, and molecular studies demonstrated the heterogeneity of such cases, including the first example of clinically typical myelofibrosis (MF) associated with a bcr gene rearrangement characteristic of chronic myelogenous leukemia (CML).
To assess the influence of graft-versus-host disease (GVHD) on recurrent leukemia and survival after allogeneic marrow transplantation, we studied 1,202 patients with acute nonlymphocytic leukemia (ANL), acute lymphocytic leukemia (ALL), and chronic myelogenous leukemia (CML) given unmodified marrow grafts from HLA-identical siblings. Proportional hazards regression models using acute GVHD and ...
