چکیده

The K562 cell line (chronic myeloid leukemia), sensitive to chemotherapy (non-MDR), and the Lucena cell line, resistant to chemotherapy (MDR) were investigated. The results suggest that both cell lines possess CD34+CD38- profiles of hematopoietic stem cell markers. The promoter regions of ABCB1, ABCG2 and ABCC1 genes contain binding sites for the Oct-4 transcripton factor, which is also considered a marker of tumor stem cells. Lucena cells showed an over-expression of the ABCB1 gene and a high expression of the Oct-4, ABCG2 and ABCC1 genes as compared to K562 cells.

Signaling pathways involved in chronic myeloid leukemia pathogenesis: the importance of targeting Musashi2-Numb signaling to eradicate leukemia stem cells

Objective(s): Chronic myeloid leukemia (CML) is a myeloid clonal proliferation disease defining by the presence of the Philadelphia chromosome that shows the movement of BCR-ABL1. In this study, the critical role of the Musashi2-Numb axis in determining cell fate and relationship of the axis to important signaling pathways such as Hedgehog and Notch that are essential ...

Multidrug resistance in chronic myeloid leukaemia: how much can we learn from MDR–CML cell lines?

The hallmark of CML (chronic myeloid leukaemia) is the BCR (breakpoint cluster region)-ABL fusion gene. CML evolves through three phases, based on both clinical and pathological features: a chronic phase, an accelerated phase and blast crisis. TKI (tyrosine kinase inhibitors) are the treatment modality for patients with chronic phase CML. The therapeutic potential of the TKI imatinib is affecte...

The long-term outcome and efficacy of PR1/BCR-ABL multipeptides vaccination in chronic myeloid leukemia: results of a 7-year longitudinal investigation

Background: Although Imatinib has revolutionized the treatment of chronic myeloid leukemia (CML), not all patients reach complete remission and a considerable proportion of the patients develop resistance to Imatinib. Material and Methods: In an attempt to increase the tail on the survival curve, we conducted a Phase I/II study of PR1/BCR-ABL multipeptides vaccination trial in CML patients wit...

Multidrug Resistance (mdr l ) Gene Expression in Adult Acute Leukemias: Correlations With Treatment Outcome and In Vitro Drug Sensitivity

Resistance to multiple chemotherapeutic agents has been related to the production of P-glycoprotein, a trans-membrane drug efflux pump that is encoded by the multidrug resistance (MDR) gene mdrl. To investigate whether mdrl could be involved in clinical resistance to chemotherapy in acute leukemias, we have analyzed retrospectively the RNA from adult acute leukemia cells by slot-blot hybridizat...

Study of STAT3 Expression in Different Phases of Patients with Chronic Myeloid Leukemia

Background and Aim: Chronic myeloid leukemia(CML) is a clonal myeloproliferative disease, characterized by BCR/ABL translocation. Using tyrosine kinase inhibitors such as Imatinib, treatment for this disease has progressed remarkably. However, resistance to tyrosine kinase inhibitor is a major obstacle. Signal transducer and activator of transcription 3(STAT3) is an important transcription fact...
