Derivative chromosome 9 deletions in chronic myeloid leukemia: poor prognosis is not associated with loss of ABL-BCR expression, elevated BCR-ABL levels, or karyotypic instability.
Deletions of the derivative chromosome 9 have recently been reported in chronic myeloid leukemia. These deletions are large, occur at the time of the Philadelphia (Ph) translocation, span the translocation breakpoint, and represent a powerful prognostic indicator. However, the molecular mechanisms responsible for the poor prognosis associated with deletions are obscure, and several possible mod...
متن کاملFrequency of BCR-ABL Fusion Transcripts in Iranian Azeri Turkish patients with Chronic Myeloid Leukemia
Background: The Philadelphia chromosome (Ph) characterized by t (9; 22) (q34; q11.2) is a reciprocal translocation giving rise to a chimeric BCR-ABL fusion gene. Incidence of Ph chromosome is over 98% in Patients with Chronic Myeloid Leukemia (CML) and around 20% in acute lymphoblastic leukemia (ALL). The finding of this fusion gene is essential for diagnosis of CML by detection of various fusi...
متن کاملEvaluation of the Effect of Curcumin and Imatinib on BCR-ABL Expression Gene in Chronic Human k562 Cells
Background and Aims: Detection of overexpression in tumor-inhibiting genes provides valuable information for leukemia diagnosis and prognosis. Chronic myeloid leukemia (CML) is a stem cell disorder determined by a well-defined genetic anomaly involving BCR-ABL translocation in the Philadelphia chromosome. Curcumin is a chemo-preventive agent for the primary cancer targets, such as the breast, p...
متن کاملDouble jeopardy from a single translocation: deletions of the derivative chromosome 9 in chronic myeloid leukemia.
Chronic myeloid leukemia (CML) is characterized by formation of a BCR-ABL fusion gene, usually as a consequence of the Philadelphia (Ph) translocation between chromosomes 9 and 22. Recently the development of new fluorescence in-situ hybridization (FISH) techniques has allowed identification of unexpected deletions of the reciprocal translocation product, the derivative chromosome 9, in 10% to ...
متن کاملDetection of abl/bcr Fusion Gene in Patients Affected by Chronic Myeloid Leukaemia by Dual-Colour Interphase Fluorescence in situ Hybridisation
Conventional cytogenetic is the standard technique for detection of Philadelphia (Ph) chromosome in chronic myeloid leukemia (CML). Evaluation of abelson murine leukemia/breakpoint cluster region (abl/bcr) fusion using dual-colour fluorescence in situ hybridization (D-FISH) is an alternative approach allowing rapid and reliable detection of the disease. We employed the technique of interphase D...
