چکیده

We evaluated the effect of the human immunodeficiency virus (HIV) protease inhibitor saquinavir on the imatinib-sensitive and imatinib-resistant chronic myelogenous leukemia cell lines. Saquinavir, which is also a proteasome blocker, showed dose- and time-related anti-proliferative activity, particularly on the imatinib-resistant lines and a pro-apoptotic effect. Association with imatinib caused a significant increase of activity.

Pregnancy Outcome of Two Patients with Chronic Myelogenous Leukemia Treated with Imatinib

Although chronic myelogenous leukemia in pregnancy is rare, its management and treatment is more difficult and complicated.Treatment of patients with chronic myelogenous leukemia includes bone marrow transplantation, however in less than 30% of patients the donor’s organ would be accepted. To this end, cytotoxic therapy is considered as an alternative therapeutic option. This option provides sa...

In vitro anti-neuroblastoma activity of saquinavir and its association with imatinib.

Neuroblastoma (NB) has a poor prognosis when in advanced stages, highlighting the need for new therapeutic options. The human immunodeficiency virus (HIV) protease inhibitor saquinavir is active in vitro against chronic myeloid leukaemia cells, in synergy with the tyrosine kinase inhibitor imatinib. Here, we evaluated the effects of saquinavir, al...

Comparative proteomic analysis of chronic myelogenous leukemia cells: inside the mechanism of imatinib resistance.

Imatinib is the first molecular targeted therapy that has shown clinical success, but imatinib acquired resistance, although a rare event, is critical during the therapy of chronic myelogenous leukaemia (CML). With the aim of better understanding the molecular mechanisms accompanying acquisition of resistance to this drug, a comparative proteomic approach was undertaken on CML cell lines LAMA 8...

Analysis of Expression Of SIRT1 Gene In Patients With Chronic Myeloid Leukemia Resistant To Imatinib Mesylate

Background: Chronic myeloid leukemia is a clonal myeloproliferative disease which is characterized by bcr/abl translocation. With the emergence of tyrosine kinase inhibitors such as imatinib mesylate, significant improvement has been made in treatment of this disease. However, drug resistance against this medicine is still an obstacle. SIRT1 is a gene with deacetylase activity which has been de...

In vitro efficacy of combined treatment depends on the underlying mechanism of resistance in imatinib-resistant Bcr-Abl-positive cell lines.

Imatinib mesylate (Gleevec, formerly STI571) is an effective therapy for all stages of chronic myelogenous leukemia (CML). While responses in chronic-phase CML are generally durable, resistance develops in many patients with advanced disease. We evaluated novel antileukemic agents for their potential to overcome resistance in various imatinib-resistant cell lines. Using cell proliferation assay...
