UNLABELLED Tyrosine kinase domain mutations are a common cause of acquired clinical resistance to tyrosine kinase inhibitors (TKI) used to treat cancer, including the FLT3 inhibitor quizartinib. Mutation of kinase "gatekeeper" residues, which control access to an allosteric pocket adjacent to the ATP-binding site, has been frequently implicated in TKI resistance. The molecular underpinnings of ...
Activating mutations of the protein tyrosine kinase (PTK) FLT3 can be found in approximately 30% of patients with acute myeloid leukemia (AML), thereby representing the most frequent single genetic alteration in AML. These mutations occur in the juxtamembrane (FLT3 length mutations; FLT3-LMs) and the second tyrosine kinase domain of FLT3-TKD and confer interleukin 3 (IL-3)-independent growth to...
Internal tandem duplication (ITD) mutations in the FLT3 tyrosine kinase have been detected in approximately 20% of acute myeloid leukemia (AML) patients. Patients harboring FLT3/ITD mutations have a relatively poor prognosis. FLT3/ITD results in constitutive autophosphorylation of the receptor and factor-independent survival. Previous studies have shown that FLT3/ITD activates the signal transd...
FMS-like tyrosine kinase 3 (FLT3) is a receptor tyrosine kinase that is constitutively activated in approximately 30% of acute myelogenous leukemia (AML) patients and appears to confer an adverse prognosis. Thus, development of inhibitors and/or antibodies that specifically target FLT3 has been of substantial interest. In this regard, phase 1 and 2 trials involving FLT3 inhibitors have recently...
Mutations in the receptor tyrosine kinase FLT3 occur frequently in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Small molecules that selectively inhibit FLT3 kinase activity induce apoptosis in blasts from AML patients with FLT3 mutations and prolong survival in animal models of FLT3-induced myeloproliferative disease. A spectrum of structurally different s...
FLT3 activating mutations are the most frequent single genetic abnormality in patients with acute myeloid leukemia. Thus targeting the FLT3 activated kinase is a promising treatment approach. We wanted to test whether the protein tyrosine kinase inhibitor SU5614 selectively eliminates leukemic stem cells while sparing their normal counterparts.
The suppressor of cytokine signaling 2 (SOCS2) is a member of the SOCS family of E3 ubiquitin ligases. SOCS2 is known to regulate signal transduction by cytokine receptors and receptor tyrosine kinases. The receptor tyrosine kinase FLT3 is of importance for proliferation, survival and differentiation of hematopoietic cells and is frequently mutated in acute myeloid leukemia. We observed that SO...
Ostra białaczka szpikowa (AML) to złożona choroba o dynamicznym przebiegu, związana z szeregiem nabytych, kumulujących się zmian genetycznych. W ostatnich latach dokonano znaczących postępów w zakresie zrozumienia patogenezy oraz możliwości diagnostycznych i terapeutycznych. Aktualne klasyfikacje uwzględniają zaburzenia cytogenetyczno-molekularne, wśród nich obecność między innymi mutacji obręb...
Purpose: FMS-like tyrosine kinase-3 (FLT3) internal tandem duplication (FLT3-ITD) mutations are common in patients with acute myeloid leukemia (AML). These patients regularly develop resistance to FLT3 inhibitors suggesting that targeted combination drug strategies are needed to enhance AML therapy
