background: the secondary genetic changes other than the promyelocytic leukemia-retinoic acid receptor (pml-rara) fusion gene may contribute to the acute promyelocytic leukemogenesis. chromosomal alterations and mutation of flt3 (fms-like tyrosine kinase 3) tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia. however, the prognostic significance of flt3 mutat...

introduction: tyrosine kinase inhibitors (tkis) were the first drugs to use an intracellular signaling molecule as a therapeutic target. unresponsiveness to tkis limits therapeutic options, making allogeneic hematopoietic stem cell transplantation (hsct) the only option leading to molecular remission. objectives: to characterize cml patients unresponsive to first- and/or second-generation tki t...

background: genistein is a soya isoflavone, which is found naturally in legumes, such as soybeans and chickpeas. radiation–induced free radicals in turn impair the antioxidative defense mechanism, leading to an increased membrane lipid peroxidation that results in damage of the membrane bound enzyme and may lead to damage or death of cell. hence, the lipid peroxidation is a good biomarker of da...

introduction: the secondary genetic changes other than the pml-rara fusion gene may contribute to the acute promyelocytic leukemogenesis. chromosomal alterations and mutation of flt3 tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia (aml). however, the prognostic significance of flt3 mutations in acute promyelocytic leukemia (apl) is not firmly established....

lung cancer is still diagnosed in advanced stage and most patients do not have the opportunity for surgical treatment. although in the recent years new diagnostic equipment is available such as the radial and linear endobronchial ultrasound (ebus) and electromagnetic fiberoptic bronchoscopy. however; novel targeted therapies with tyrosine kinase inhibitors of second generation and immunotherapy...

mpns including a heterogeneous group of clonal or oligoclonal hamtopathies characterized by proliferation and accumulation of mature myeloid cells. jak2 tyrosine kinase mutation is the most common molecular lesion identified in 90% of cases. jak2 is involved in epo signaling pathway, and mutations in it lead to epo-independent spontaneous phosphorylation. most tyrosine kinase inhibitors (tki) a...

In this study, we aimed to determine VEGFR-2, EGFR and PDGFR-β tyrosine kinase inhibitory activities of some pyrrolo[2,3-d]pyrimidine derivatives previously synthesized and showed potent cytotoxic and apoptotic effects against several cancer cell lines by our group and to evaluate the relationships between inhibitory activities and binding properties of the active compounds by molecular docking...

acute lymphoblastic leukemia(all) is due to early stage arrest of lymphoblast development. the translocation of philadelphia (ph) chromosome occurs as a result of the bcr-abl fusion gene, which constitutively produced activated tyrosine kinase. this gene fusion is an important indicator for prognosis in all and is associated with poor overall survival and remission duration. bcr-abl could inter...

long-term potentiation (ltp) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. studies in recent years indicate the importance of molecular pathways in the development of memory and learning. tropomyosin receptor kinase b (trkb) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...
