HYPOTHESIS To determine the expression of the tyrosine kinases platelet-derived growth factor receptor (PDGFR) and c-Kit in vestibular schwannoma (VS) and to determine the potential role of imatinib mesylate (Gleevec) in regulating the growth and cell death of this tumor. BACKGROUND Protein tyrosine kinases are transmembrane tyrosine kinase receptors that transduce signals from inside and out...
Gleevec (STI571, imatinib mesylate) is the first major success in the development of targeted anticancer therapies. This oral drug was designed “from the ground up” as an inhibitor of the ABL tyrosine kinase, which becomes constitutively expressed and activated as a result of its fusion to BCR in chronic myelogenous leukemia (CML). Early clinical studies were so promising that the US Food and D...
Schwannomas, although benign, can be fatal or give rise to significant morbidity due to an unpredictable growth rate. They can reoccur after surgery or radiation, current treatments each with significant inherent risks. These risks are further amplified in neurofibromatosis type 2 (NF2), a germ line predisposition syndrome characterized by multiple schwannomas, underlying the need for biologica...
PBT-3 is one of a family of stable chemical analogs of the hepoxilins, products derived from arachidonic acid. We previously showed that PBT-3 caused apoptosis in the chronic myelogenous leukemia (CML) cell line K-562 in vitro (Anti-cancer Res 23: 3617-3622, 2003). It was as effective as Gleevec, a novel agent that blocks tyrosine kinase activity during treatment of CML. We describe, herein, th...
Neurotoxic amyloid-β peptides (Aβ) are major drivers of Alzheimer's disease (AD) and are formed by sequential cleavage of the amyloid precursor protein (APP) by β-secretase (BACE) and γ-secretase. Our previous study showed that the anticancer drug Gleevec lowers Aβ levels through indirect inhibition of γ-secretase activity. Here we report that Gleevec also achieves its Aβ-lowering effects throu...
چکید ه سابقه و هدف لوسمی میلوئید مزمن (cml) بیماری است که به دلیل موتاسیون اختصاصی در سلول های بنیادی چند قوه ای مغزاستخوان ایجاد می شود. وجود کروموزوم فیلادلفیا و عوامل ژنتیک در این بیماری برای نخستین بار در سال 1973 گزارش گردید. امروزه وجود محصول ژن اتصال یافته bcr-abl که دارای فعالیت غیرطبیعی تیروزین کینازی است و موجب بی نظمی در تکثیر سلول ها می شود در این بیماری ثابت شده است. در این بررسی...
