Acute myeloid leukemias with reciprocal rearrangements can be distinguished by specific gene expression profiles.
Acute myeloid leukemia (AML) is a heterogeneous group of genetically defined diseases. Their classification is important with regard to prognosis and treatment. We performed microarray analyses for gene expression profiling on bone marrow samples of 37 patients with newly diagnosed AML. All cases had either of the distinct subtypes AML M2 with t(8;21), AML M3 or M3v with t(15;17), or AML M4eo w...
متن کاملExpression profiles of acute lymphoblastic and myeloblastic leukemias with ALL-1 rearrangements.
The ALL-1 gene is directly involved in 5-10% of acute lymphoblastic leukemias (ALLs) and acute myeloid leukemias (AMLs) by fusion to other genes or through internal rearrangements. DNA microarrays were used to determine expression profiles of ALLs and AMLs with ALL-1 rearrangements. These profiles distinguish those tumors from other ALLs and AMLs. The expression patterns of ALL-1-associated tum...
متن کاملPrognostically useful gene-expression profiles in acute myeloid leukemia.
BACKGROUND In patients with acute myeloid leukemia (AML) a combination of methods must be used to classify the disease, make therapeutic decisions, and determine the prognosis. However, this combined approach provides correct therapeutic and prognostic information in only 50 percent of cases. METHODS We determined the gene-expression profiles in samples of peripheral blood or bone marrow from...
متن کاملRearrangements and aberrant expression of the retinoic acid receptor alpha gene in acute promyelocytic leukemias
Although acute promyelocytic leukemias (APLs) are consistently associated with a reciprocal chromosome 15;17 translocation, the gene(s) directly affected by the breakpoints have never been isolated. The chromosome 17 breakpoint maps to near the retinoic acid receptor alpha (RAR alpha) locus. Investigation of 20 APLs and a large series of other neoplastic patients and normal controls revealed RA...
متن کاملEvaluation of the CD123 Expression and FLT3 Gene Mutations in Patients with Acute Myeloid Leukemia
Background and Objective: Identification of cytogenetic and molecular changes plays an important role in acute myeloid leukemia (AML) patients. Thus, they are used in classification, prognosis and treatment of the disease. The CD123 expression and FLT3 gene mutations are also the variations that may assist in prognosis and treatment of patients with AML.Methods:</...
