Chronic myeloid leukemia (CML) is a clonal disease characterized by the presence of Philadelphia chromosome and its oncogenic product, BCR-ABL, which activates multiple pathways involved in cell survival, growth promotion, progression. We recently reported that signal-transducing adaptor protein 1 (STAP-1) upregulated CML stem cells (LSCs) functions to reduce apoptosis LSCs upregulating STAT5-d...

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...

Although the BCR-ABL hybrid gene on chromosome 22q-plays a pivotal role in the pathogenesis of chronic myeloid leukemia (CML), little is known of the reciprocal chimeric gene, ABL-BCR, formed on chromosome 9q+. By reverse transcription/polymerase chain reaction amplification (RT/PCR) we have detected ABL-BCR mRNA in cells from 31 of 44 BCR-ABL positive CML patients and 3 of 5 CML cell lines. Of...

IgG-containing B cell antigen receptor (IgG-BCR), the BCR mostly expressed on memory B cells, contains a distinct signaling function from IgM-BCR or IgD-BCR expressed on naïve B cells. Because naïve B cells transgenic for IgG exhibit augmented response to antigens similar to memory B cells, the distinct signaling function of IgG-BCR appears to play a role in augmented antibody responses of memo...

The BCR protein is involved in the inhibition of oncogenic activity of the Bcr-Abl oncoprotein. This inhibition is believed to be the result of binding to the SH2 domain of Bcr-Abl in a non-phosphotyrosine-dependent manner. We showed that the Arg to Leu mutation in the Phe-Leu-Val-Arg-Glu-Ser (FLVRES) sequence of the SH2 domain, known to interfere with phosphotyrosine sequence binding, did not ...

BACKGROUND Some reports have suggested that chronic myeloid leukemia (CML) patients have a higher prevalence of M-bcr than acute lymphoblastic leukemia (ALL) patients, which show a higher prevalence of m-bcr. However, the relationship between BCR-ABL subtypes and progression of CML and ALL remains unclear. MATERIALS AND METHODS 354 CML chronic phase (CML-CP) patients, 26 CML blastic phase (CM...

It has been suggested that the BCR-ABL gene of chronic myeloid leukemia (CML) is not uniformly expressed in Philadelphia (Ph)-positive cells, and that BCR-ABL gene expression precludes transcription of the normal BCR or ABL genes. Therefore, we have analyzed granulocyte-macrophage colony-forming unit (CFU-GM) colonies derived from peripheral blood of 11 CML patients by cytogenetic and by revers...

Fully controlled rectifier and Battery Charge Regulator (BCR). BCR is the main unit of UPS ( Uninterruptable Power Supply ) equipment. The fully has function supplying voltage directly to BCR, regulating battery charge. Forced charging at a constant with current that matches life will have an impact on decreasing life, besides it efficiency using battery. Controlling input as regulated by magni...

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...
