Project description:Gene profiles from three dasatinib-resistant and three dasatinib-sensitive pancreatic cancer cell lines were compared by microarray analysis. RNA from three dasatinib-resistant (MiaPaCa2, Panc1, SU8686) and three dasatinib-sensitive (Panc0504, Panc0403, Panc1005) pancreatic cancer cell lines were extracted. Biological triplicates were employed for each cell line. Complementary DNA microarray analysis was performed using Illumina Human HT-12 v4 BeadChip (Illumina, San Diego, CA) at the National University of Singapore Core Facility following the manufacturer’s instructions.

Project description:Purpose: Several ALL subtypes have been described depending on their karyotype, cell type, immunophenotype and gene-expression profile. Recently, a novel ALL subtype has been described and is characterized by expression of the pre-B cell receptor (pre-BCR). Interestingly, half of the cases is associated with the chromosomal translocation t(1:19), coding for the chimeric fusion protein E2A-PBX1, which is present in about 5% of pediatric and adult ALL. Using preclinical models, we and other groups have shown very promising preclinical activity of dasatinib in pre-BCR+ ALL and early clinical evidence supports our observations. To study mechanism of acquired dasatinib resistance, we generated dasatinib-resistant pre-BCR+/E2A-PBX1+ cell lines through multiple passages in the presence of increasing drug concentrations. Whole transcriptome analysis of dasatinib-sensitive and resistant ALL cells were performed to detect systematically differentially expressed genes and enriched pathways involved in dasatinib resistance.

Project description:Transcriptional profiling was conducted on RNA from 16 prostatic cancer cell lines to identify genes whose expression level correlate with sensitivity of an anti-tumor agent (dasatinib). Keywords: comparison of sensitive group versus resistant group of cell lines to agent

Project description:Mechanisms of resistance and sensitivity to the multi-targeted kinase inhibitor dasatinib are unknown. We previously found that lung cancer cells with kinase-inactivating BRAF mutations are sensitive to dasatinib and undergo senescence whereas cells with wild type BRAF are resistant. To better understand mechanisms underlaying the differential sensitivity of lung cancer cells to dasatinib, we performed gene expression profiling of lung cancer cells with (sensitive) and without (resistant) kinase-inactivating BRAF mutations

Project description:A phase I trial of a SRC kinase Inhibitor, dasatinib, in combination with paclitaxel and carboplatin in patients with advanced or recurrent ovarian cancer. Background: We conducted a phase I study of dasatinib, an oral SRC tyrosine kinase inhibitor, in combination with paclitaxel and carboplatin in advanced and recurrent epithelial ovarian cancer (EOC). Methods: The primary objective was to determine the maximum tolerated dose (MTD). Secondary objectives included toxicity, response rate (RR), pharmacokinetics and pharmacodynamics. Based on the 3+3 design, cohorts of 3-6 pts received paclitaxel 175 mg/m2 and carboplatin AUC 6 every three weeks with escalating doses of dasatinib (100, 120, 150 mg daily), followed by an 8 patient expansion cohort. Results: Twenty patients were enrolled between 06/07 and 12/09. The median age was 61 yrs (42-82) with a median of 2 prior regimens (0-6), and 71% had platinum-sensitive disease. There were 3-6 pts in each cohort, and 8 in the expansion cohort. Pharmacokinetics were observed over the first 2 cycles of therapy. One DLT was observed in the 100 mg dasatinib cohort (grade 3 myalgia. Other toxicities in all cycles included neutropenia (95% grade 3-4), thrombocytopenia (35% grade 3-4), and fatigue (10% grade 3). The RR was 45% (complete responses, 3/18(17%); partial responses, 5/18(28%)) and 56% (10/18) had stable disease. The PFS6-month actuarial estimate was 86%. The median PFS and OS were 7.8 and 16.2 months, respectively. Conclusions: Due to the high incidence of myelosuppression with subsequent cycles the recommended phase II dose is 150 mg daily of dasatinib in combination with paclitaxel and carboplatin. The combination was safe with evidence of clinical activity in advanced EOC. Global profiles of expression were characterized using unsupervised clustering methods and gene- and pathway-analyses of differential expression.

Project description:Long-term treatment of Kasumi-1 cells at clinically attained doses of dasatinib led to decreased drug-sensitivity by means of IC50 values (relative to treatment-naive cells). Changes were paralled by profound alterations in c-KIT expression and cell signaling signatures. Upon brief discontinuation of dasatinib treatment, these alterations reversed and drug sensitivity was restored. We used gene expression profiling to examine reversal of dasatinib-resistance at the molecular/expression level. Kasumi-1 cells were either treated with dasatinib for 12 weeks (R48) or left untreated (K). Subsequently, dasatinib was withdrawn from R48 cells for 1 week (PR48). RNA was extracted from R48 and K cells and hybridized on Affymetrix microarrays after 12 weeks and PR48 after a total time span of 13 weeks.
