with the present specifications for clasification, 95% of chronic myelogeneous leukaemia (cml) cases have the t(9;22), which brings the abl oncogene to the bcr region and results in a hybrid gene bcr/abl. there may be involvement of other chromosomes in 2-10%, and secondry or additional chromosome abberations may present in 60-80% during the progression of the disease. in the majority of the re...

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a b...

The Bcr-Abl oncoprotein is the primary causative factor in Philadelphia chromosome-associated leukemias. The activated tyrosine kinase of the Bcr-Abl oncoprotein is the primary driving force behind its oncogenic activity. We report here that a deleted form of Bcr [Bcr(64-413)], encompassing the Abl SH2 binding domains of Bcr, reduced the phosphotyrosine content of c-Abl and Bcr-Abl within cells...

The aim of this retrospective study was to identify clinical predictors early biochemical recurrence (BCR) in patients with high-risk prostate cancer (PCa) treated carbon-ion radiotherapy (CIRT) and androgen deprivation therapy (ADT). A total 670 PCa CIRT ADT were included the study. Early BCR defined as occurring during adjuvant after or within 2 years completion ADT. Univariate multivariate a...

Chronic Myeloid Leukemia (CML) is a hematopoietic malignancy characterized by the presence ofPhiladelphia (Ph1) chromosome that results from balanced reciprocal translocation between chromosomes9 and 22 leading in the formation of bcr/abl fusion gene. The present study was conducted to evaluate cytogenetic and molecular abnormalities in CML patients at presentation and during the co...

Bcr is a serine/threonine kinase activated by platelet-derived growth factor that is highly expressed in the neointima after vascular injury. Here, we demonstrate that Bcr is an important mediator of angiotensin (Ang) II and platelet-derived growth factor-mediated inflammatory responses in vascular smooth muscle cells (VSMCs). Among transcription factors that might regulate Ang II-mediated infl...

jak2 is a tyrosine kinase that plays an important role in the signaling pathways of many hematopoietic growth factor receptors. a single acquired point mutation – v617f – in jak2 occurs in the great majority of patients with polycythemia vera (pv) and approximately half of the patients with idiopathic myelofibrosis (imf) or essential thrombocythemia (et). in contrast, the jak2-v617f mutation is...

Small interfering RNAs (siRNAs) were designed to target the bcr-abl oncogene, which causes chronic myeloid leukemia (CML) and bcr-abl-positive acute lymphoblastic leukemia (ALL). Chemically synthesized anti-bcr-abl siRNAs were selected using reporter gene constructs and were found to reduce bcr-abl mRNA up to 87% in bcr-abl-positive cell lines and in primary cells from CML patients. This mRNA r...
