introduction: imatinib, a tyrosine kinase inhibitor which resulted in much improvement in the treatment of chronic myelogenous leukemia (cml), may adversely affect thyroid gland function. to date, assessment of thyroid function during imatinib therapy has limited to retrospective studies. the aim of this study was to evaluate the effects of imatinib on thyroid function in a prospective manner. ...
experimental autoimmune encephalomyelitis (eae) is a mouse model for multiple sclerosis (ms), this autoimmune disease is mainly mediated by adaptive and innate immune responses that lead to an inflammatory demyelination and axonal damage. imatinib mesylate is a selective protein tyrosine kinase inhibitor with immunomodulatory properties that abrogates multiple signal transduction p...
introduction: imatinib mesylate is a selective inhibitor of tk and is considered now to be the frontline therapeutic agent during the chronic phase of cml. we have evaluated the efficacy of it on children with chronic-phase of cml. patients and methods: in a clinical trial study over the past 3 years, 14 patients (8 females and 6 males, 2.5-14 years old) were admitted with a diagnosis of cml. s...
Purpose. This retrospective, nonrandomized study investigated the effect of imatinib rechallenge plus best supportive care (BSC) on overall survival after imatinib and sunitinib treatment for patients with locally advanced or metastatic gastrointestinal stromal tumor (GIST). Methods. Twenty-six patients who had previously been exposed to both imatinib and sunitinib were enrolled in this study. ...
This retrospective multicenter study in patients with chronic myeloid leukemia in chronic phase was undertaken to confirm the clinical relevance of imatinib plasma concentrations monitoring in daily practice. Forty-one patients, with 47 imatinib plasma measurements, were analyzed during treatment with imatinib given at a fixed 400mg daily dose. A significant inverse relationship of imatinib con...
Although imatinib is highly effective in the treatment of chronic myeloid leukemia (CML), 25-30% patients do not respond or relapse after initial response. Imatinib uptake into targeted cells is crucial for its molecular response and clinical effectiveness. The organic cation transporter 1 (OCT1) has been proposed to be responsible for this process, but its relevance has been discussed controve...
Imatinib (Gleevec), a non-receptor tyrosine kinase inhibitor (nRTKI), is one of the most successful anti-neoplastic drugs in clinical use. However, imatinib-resistant mutations are increasingly prevalent in patient tissues and driving development of novel imatinib analogs. We present a detailed study of the conformational dynamics, in the presence and absence of bound imatinib, for full-length ...
BACKGROUND Recently, the IMPRES study revealed that systemic imatinib improves exercise capacity in patients with advanced pulmonary arterial hypertension. Imatinib blocks the tyrosine kinase activity of the platelet-derived growth factor (PDGF)-receptor (PDGFR), acts antiproliferative and relaxes pulmonary arteries. However so far, the relaxant effects of imatinib on pulmonary veins (PVs) and ...
BACKGROUND Imatinib is a tyrosine kinase inhibitor that is used to treat chronic myelogenous leukemia (CML). BCR-ABL mutations are associated with failure of imatinib treatment in many CML patients. LYN kinase regulates survival and responsiveness of CML cells to inhibition of BCR-ABL kinase, and differences in LYN regulation have been found between imatinib-sensitive and -resistant CML cell li...
Gastrointestinal stromal tumors (GIST) are the most common adult sarcomas and the oncogenic driver is usually a KIT or PDGFRA mutation. Although GISTs are often initially sensitive to imatinib or other tyrosine kinase inhibitors, resistance generally develops, necessitating backup strategies for therapy. In this study, we determined that a subset of human GIST specimens that acquired imatinib r...
