PURPOSE Chronic myeloid leukemia (CML) is caused by reciprocal translocation between chromosomes 9 and 22, forming BCR-ABL, a constitutively activated tyrosine kinase. Imatinib mesylate, a selective inhibitor of BCR-ABL, represents current frontline therapy for CML; however, emerging evidence suggests that drug resistance to imatinib may limit its long-term(More)
The insulin-like growth factor I receptor (IGF-IR) is a transmembrane tyrosine kinase that is essential to growth and development and also thought to provide a survival signal for the maintenance of the transformed phenotype. There has been increasing interest in further understanding the role of IGF-I signaling in cancer and in developing receptor(More)
Purpose: The epidermal growth factor receptor (EGFR), a protein tyrosine kinase expressed in many types of human cancers including colon and breast, has been strongly associated with tumor progression. Cetuximab, an IgG1 anti-EGFR chimeric mouse/human monoclonal antibody, has been proven to be effective in the treatment of advanced colon cancer. To date,(More)
Although Erbitux (cetuximab) has proven therapeutic benefit in the clinical setting, the molecular determinants predicting responsiveness to this agent are still not very well understood. Here, we assessed the relationship between basal total and activated (pY1068) epidermal growth factor receptor (EGFR) levels in a tumor and the responsiveness to cetuximab(More)
Dasatinib (BMS-354825) is a potent, oral multi-targeted kinase inhibitor. It is an effective therapy for patients with imatinib-resistant or -intolerant Ph+ leukemias,. It has demonstrated promising preclinical anti-tumor activity, and is under clinical evaluation in solid tumors. To support the clinical development of dasatinib, we identified a(More)

PURPOSE Epidermal growth factor receptor (EGFR), a protein tyrosine kinase expressed in many types of human cancers, has been strongly associated with tumor progression. Cetuximab is an IgG(1) anti-EGFR chimeric mouse/human monoclonal antibody that has been approved for the treatment of advanced colon cancer. Using human tumor xenografts grown in nude mice,(More)
12017 Background: Ixabepilone belongs to a class of structurally novel, microtubule-stabilizing agents that exert their antimitotic action by binding to tubulin with a binding mode that is distinct from the taxanes. Preclinical findings that ixabepilone has antitumor activity in a broad spectrum of tumor types, including taxane-resistant tumors, is borne(More)
Tetrahydroquinoline-based small molecule inhibitors of farnesyltransferase (FT) have been identified. Lead compounds were shown to have nanomolar to sub-nanomolar activity in biochemical assays with excellent potency in a Ras-mutated cellular reversion assay. BMS-316810 (9e), a 0.7 nM FT inhibitor, was orally-active in a nude mouse tumor allograft efficacy(More)
