BACKGROUND Platelet-derived growth factor receptor A is altered by amplification and/or mutation in diffuse intrinsic pontine glioma (DIPG). We explored in vitro on new DIPG models the efficacy of dasatinib, a multi-tyrosine kinase inhibitor targeting this receptor. METHODS Gene expression profiles were generated from 41 DIPGs biopsied at diagnosis and compared with the signature associated w...
PURPOSE The Src family of kinases (SFKs) regulate multiple signal transduction cascades and influence proliferation, motility, survival, and angiogenesis. Dasatinib inhibits SFKs, which leads to cytotoxicity, cell cycle arrest, apoptosis, and decreased invasion of cancer cells. Signal transducer and activator of transcription 3 (STAT3) is a latent transcription factor that regulates survival an...
BACKGROUND Less than 50% of ovarian cancers respond to paclitaxel. Effective strategies are needed to enhance paclitaxel sensitivity. METHODS A library of silencing RNAs (siRNAs) was used to identify kinases that regulate paclitaxel sensitivity in human ovarian cancer SKOv3 cells. The effect of dasatinib, an inhibitor of Src and Abl kinases, on paclitaxel sensitivity was measured in ovarian c...
Elevated levels of Src kinase expression have been found in a variety of human epithelial cancers. Most notably in colon cancer, elevated Src expression correlates with malignant potential and is also associated with metastatic disease. Dasatinib (BMS-354825) is a novel, orally active, multi-targeted kinase inhibitor that targets Src family kinases and is currently under clinical evaluation for...
Dasatinib is an oral potent adenosine triphosphate (ATP)–competitive inhibitor of BCR-ABL, cKIT, platelet-derived growth factor receptor, and SRC family kinases (SFKs), which has demonstrated high efficiency in patients with imatinib-resistant chronic myelogenous leukemia. Here, we show that dasatinib weakly affects platelet activation by thrombin or adenosine diphosphate but is a potent inhibi...
Tyrosine kinase inhibitors (TKIs) like dasatinib and nilotinib are indicated as second-line treatment for chronic myeloid leukemia resistant or intolerant to the current first-line TKI imatinib. These are agents are well tolerated, but potent and as such should be monitored for potentially serious side-effects like fluid retention and pleural effusions. Here we present key clinical trial data a...
Reactive cardiac fibrosis resulting from chronic pressure overload (PO) compromises ventricular function and contributes to congestive heart failure. We explored whether nonreceptor tyrosine kinases (NTKs) play a key role in fibrosis by activating cardiac fibroblasts (CFb), and could potentially serve as a target to reduce PO-induced cardiac fibrosis. Our studies were carried out in PO mouse my...
PURPOSE Imatinib, a BCR-ABL tyrosine kinase inhibitor, is a substrate of the efflux transporters P-glycoprotein (P-gp; ABCB1) and ABCG2 (breast cancer resistance protein), and its brain accumulation is restricted by both transporters. For dasatinib, an inhibitor of SCR/BCR-ABL kinases, in vivo interactions with P-gp and ABCG2 are not fully established yet. EXPERIMENTAL DESIGN We used Abcb1a/1...
Dasatinib is an orally available broad-spectrum tyrosine kinase inhibitor that is widely used to treat chronic myeloid leukemia. It is also in clinical trials for the treatment of other malignancies, including solid tumors. Despite its wide use, little is known of its effects on normal hematopoietic stem and progenitor cells. Here, we study wild-type mice dosed with dasatinib and find that it c...
UNLABELLED Intrahepatic cholangiocarcinoma (ICC) is an aggressive liver bile duct malignancy exhibiting frequent isocitrate dehydrogenase (IDH1/IDH2) mutations. Through a high-throughput drug screen of a large panel of cancer cell lines, including 17 biliary tract cancers, we found that IDH mutant (IDHm) ICC cells demonstrate a striking response to the multikinase inhibitor dasatinib, with the ...
