Leukemia/lymphoma-associated gene fusions in normal individuals.
نویسنده
چکیده
Hematopoietic neoplasias are characterized by recurrent chromosomal aberrations that result in the formation of gene fusions and the subsequent expression of chimeric proteins with unique properties. However, in recent years, different lymphoma/leukemia-associated rearrangements, such as BCR/ABL, IGH/BCL2, ETV6/RUNX1 and MLL duplications, have been detected in healthy individuals. The presence of these rearrangements indicates that such translocations can be generated in normal hematopoietic cells without apparent oncogenic consequences. This article reviews and discusses the data available in the literature.

Expression of ROR1 Gene in Patients with Acute Lymphoblastic Leukemia
Background: Acute lymphoblastic leukemia (ALL) results from genetic alterations in a single lymphoid progenitor cell. Expression of ROR1 is reported to be increased in ALL and mantle cell lymphoma. In this study the expression of ROR1 was assessed in newly diagnosed patients with ALL. Methods: This study was carried out on 40 patients with newly diagnosed ALL and healthy individuals as contro...
متن کاملNew Fusion Transcripts Identified in Normal Karyotype Acute Myeloid Leukemia
Genetic aberrations contribute to acute myeloid leukemia (AML). However, half of AML cases do not contain the well-known aberrations detectable mostly by cytogenetic analysis, and these cases are classified as normal karyotype AML. Different outcomes of normal karyotype AML suggest that this subgroup of AML could be genetically heterogeneous. But lack of genetic markers makes it difficult to fu...
متن کاملAnalysis of BAALC gene Expression as prognosis factor in Pediatric Acute Myeloid Leukemia in Iran
Background:Brain and Acute Leukemia Cytoplasmic (BAALC) is a gene which its expression is confined to progenitor cells; therefore, no expression has been illustrated in mature cells of bone marrow or white blood cells (WBC). In addition, high BAALC expression is associated with poor prognosis in Acute Myeloid Leukemia (AML) individuals and is considered as an important risk factor in Cyto...
متن کاملEvaluation of BAALC gene expression in normal cytogenetic acute myeloid leukemia patients in north-east of Iran
Background: Acute myeloid leukemia (AML) is known as one of the most common leukemia among adults. Environmental and different genetic factors affect disease process, prognosis and treatment. Among different genetic factors NPM1, FLT3, MLL and BAALC genes are the most effective on patient's survival rate. The aim of this study was to assess amount of BAALC gene expression in AML patients, and i...
متن کاملAssociation of TPMT (rs1800460) Gene Polymorphism with Childhood Acute Lymphoblastic Leukemia in a Population from Guilan, Iran
Acute lymphoblastic leukemia (ALL) is a malignant transformation and proliferation of lymphoid progenitor cells in bone marrow and blood, which is mainly found in children. Thiopurine methyltransferase (TPMT) is a thiopurine drug metabolizer enzyme that is prescribed for the treatment of ALL. Several single nucleotide polymorphisms in the TPMT gene have been reported to be associated with the d...
