Molecular pathways: BCR-ABL.

Aberrant tyrosine kinase activity plays a critical role in many hematologic disorders, including chronic myeloid leukemia characterized by the constitutive activity of BCR-ABL. ABL therefore represents a crucial target for new therapeutic strategies. Here, we summarize the molecular pathways that are abnormally activated by the oncoprotein. Such pathways may provide additional opportunities to ...

بررسی مقدماتی اثر دو روش درمانی بر بیان ژن BCR-ABL در بیماران مبتلا به CML

  چکید ه   سابقه و هدف   لوسمی میلوئید مزمن (CML) بیماری است که به دلیل موتاسیون اختصاصی در سلول‌های بنیادی چند قوه‌ای مغزاستخوان ایجاد می‌شود. 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 بی‌نظمی در تکثیر سلول‌ها می‌شود در این بیماری ثابت شده است. در این ب...

BCR-ABL and Human Cancer

The BCR-ABL oncogene was the first chromosomal abnormality shown to be associated with a specific human malignancy, the chronic myelogenous leukemia (CML), resulting from a reciprocal t(9;22) translocation characterized by the formation of a shortened chromosome, named Philadelphia chromosome (Ph), in which the tyrosine kinase of c-ABL is constitutively activated. This chromosomal translocation...

1 Molecular pathways : BCR - ABL

Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. Abstract Aberrant Tyrosine kinase (TK) activity is critical in many hematological disorders, including chronic myeloid leukemia (CML) characterized by the constitutive activity of BCR-ABL. ABL therefore represented a crucial target for new therapeutic strategies. The molecular pathways abnormal...

Tyrosine phosphorylation of P160 BCR by P210 BCR-ABL.

It is well established that the chimeric BCR-ABL gene formed by joining parts of the BCR and ABL genes plays a key role in the pathogenesis of Philadelphia (Ph) chromosome-positive leukemias. We report that simultaneous expression of P210 BCR-ABL and P160 BCR in simian COS-1 cells yielded stable complexes of these two proteins, and induced phosphorylation of P160 BCR on tyrosine residues in viv...

Bcr and Abl interaction: oncogenic activation of c-Abl by sequestering Bcr.

c-Abl tyrosine kinase is under rigorous control because of an unknown cellular inhibitor that maintains c-Abl in a relatively inactive state. Because SH2 domains are positive regulators of the nonreceptor tyrosine kinases, we tested whether this putative inhibitor would bind to an Abl SH2 protein construct and thus activate the c-Abl tyrosine kinase. Expression of a Mr 10,000 Abl SH2 protein in...
