background: previous studies have shown that leukemogenic chromosomal translocations, including fusions between break point cluster region (bcr) and abelson (abl) are present in the peripheral blood of healthy individuals. the aim of this study was to gain insights into the genetic alterations other than bcr-abl translocation in molecular level, which cause chronic myeloid leukemia (cml). metho...
Imatinib mesylate (IM) binds to the BCR-ABL protein, inhibiting its kinase activity and effectively controlling diseases driven by this kinase. IM resistance has been associated with kinase mutations or increased BCR-ABL expression. However, disease progression may be mediated by other mechanisms that render tumor cells independent of BCR-ABL. To demonstrate this potential, IM-resistant cells w...
The differentiation and apoptosis-sensitizing effects of the Bcr-Abl-specific tyrosine kinase inhibitor CGP57148B, also known as STI-571, were determined in human Bcr-Abl-positive HL-60/Bcr-Abl and K562 cells. First, the results demonstrate that the ectopic expression of the p185 Bcr-Abl fusion protein induced hemoglobin in the acute myeloid leukemia (AML) HL-60 cells. Exposure to low-dose cyto...
In Ph(+) chronic myeloid leukemia (CML), the constitutively active Bcr-Abl kinase leads to the up-regulation and activation of multiple genes, which may subsequently result in the expression of leukemia-associated antigens. In this study, we investigated the immunogenicity of Bcr-Abl-regulated antigens by stimulating CD8(+) T lymphocytes with autologous dendritic cells transfected with RNA codi...
c-Abl is a nonreceptor tyrosine kinase that is activated by certain DNA-damaging agents. The present studies demonstrate that nuclear c-Abl binds constitutively to the protein tyrosine phosphatase SHPTP1. Treatment with ionizing radiation is associated with c-Abl-dependent tyrosine phosphorylation of SHPTP1. The results demonstrate that the SH3 domain of c-Abl interacts with a WPDHGVPSEP motif ...
c-Abl kinase is maintained in its normal inactive state in the cell through an assembled, compact conformation. We describe two chemical series that bind to the myristoyl site of the c-Abl kinase domain and stimulate c-Abl activation. We hypothesize that these molecules activate c-Abl either by blocking the C-terminal helix from adopting a bent conformation that is critical for the formation of...
Endothelial dysfunction is associated with diverse cardiovascular pathologies. Here, we show a previously unappreciated role for the Abelson (Abl) family kinases (Abl and Arg) in endothelial function and the regulation of angiogenic factor pathways important for vascular homeostasis. Endothelial Abl deletion in Arg-null mice led to late-stage embryonic and perinatal lethality, with mutant mice ...
Abstract In this work we study the wake of a yawed wind-turbine model immersed in an atmospheric boundary layer (ABL). The ABL is replicated wind tunnel by means barrier-spires and distributed roughness configuration representative rural terrain. We quantify properties horizontal plane at hub height compare predictions available models to our data for different yaw angles. It found that based o...
BACKGROUND The v-abl oncogene of the Abelson murine leukemia virus (A-MuLV) encodes a cytoplasmic tyrosine kinase that can associate with phosphoinositide 3-kinase, Shc and Grb2, and activate the pathway that leads from Ras to mitogen-activated protein (MAP) kinase. Despite the link to these mitogenic signal transducers, v-Abl does not stimulate cell growth in general. Only a subset of NIH3T3 c...
The c-Fes protein-tyrosine kinase exhibits strong expression in myeloid hematopoietic cells. Previous studies have shown that Fes induces differentiation in the chronic myelogenous leukemia-derived cell line K-562, suggesting that the Fes signal for differentiation is dominant to the Bcr-Abl signal for transformation in these cells. In addition, Fes has been shown to associate with and phosphor...
