Proteomics analysis of synergistic drug combination of midostaurin and BMS-754807 in Ewing sarcoma ASP14 cell line

ABSTRACT: We used quantitative mass spectrometry-based proteomics to unravel global changes in the phosphoproteome upon treatment of ASP14 cells (a Ewing Sarcoma cell line) according to the setup below. The combination of drugs were experimentally shown to infer synergy in terms of cell killing. Three experiments were performed using a triple SILAC setup (Light: Lys0,Arg0; Medium: Lys4,Arg6; and Heavy: Lys8,Arg10): Experiment 1: Light SILAC: Drug combination (90 nM Midostaurin + 20 nM BMS-754807) Medium SILAC: Midostaurin (90 nM) Heavy SILAC: 0.1% DMSO Experiment 2: Light SILAC: Drug combination (90 nM Midostaurin + 20 nM BMS-754807) Medium SILAC: Midostaurin (90 nM) Heavy SILAC: BMS-754807 (20 nM) Experiment 3: Light SILAC: Drug combination (90 nM Midostaurin + 20 nM BMS-754807) Medium SILAC: BMS-754807 (20 nM) Heavy SILAC: 0.1% DMSO ASP14 cells were starved by replacing complete SILAC medium with SILAC minimal medium without serum over night. Cells were treated with drugs as stated above for 2h; then they were stimulated with serum for 20 minutes and harvested thereafter.

Improvements in survival for Ewing sarcoma pediatric and adolescent patients have been modest over the past 20 years. Combinations of anticancer agents endure as an option to overcome resistance to single treatments caused by compensatory pathways. Moreover, combinations are thought to lessen any associated adverse side effects through reduced dosing, which is particularly important in childhood tumors. Using a parallel phenotypic combinatorial screening approach of cells derived from three pedi ...[more]

Project description:We used mass spectrometry-based proteomics to unravel anaplastic lymphoma kinase (ALK) signaling in the ALK and MYCN amplified neuroblastoma cell line, NB1. We specifically measured the ALK interactome, phosphoproteome, phosphotyrosine interactome and proteome as outlined below. ALK Interactome and phosphoproteome: For each experiment, three SILAC conditions (‘Light’: Lys0,Arg0, ‘Medium’: Lys4,Arg6, ‘Heavy’: Lys8,Arg10) of NB1 cells were treated for 30 minutes with each of the following ALK-targeting small-molecule inhibitors: TAE684 (100 nM), crizotinib (500 nM), and LDK378 (250 nM). The experiments were performed as specified below: Experiment 1: Light: 500 nM crizotinib, Medium: 100 nM TAE684, Heavy: 0.1% DMSO Experiment 2: Light: 100 nM TAE684, Medium: 250 nM LDK378, Heavy: 0.1% DMSO Experiment 3: Light: 250 nM LDK378, Medium: 500 nM crizotinib, Heavy: 0.1% DMSO These three triple-SILAC experiments allowed the effect of each inhibitor to be measured in duplicates. ALK phosphotyrosine interactome: To identify phosphotyrosine-specific interaction partners of ALK we used a label-free mass spectrometry-based proteomics approach. Interacting proteins to the peptide sequences (phosphorylated and non-phosphorylated peptide) indicated in the table below were identified by a peptide pull-down assay and mass spectrometry. Peptide pull-downs were performed on NB1 cell lysate prepared from cells treated for 30 minutes with LDK378 (250 nM) or DMSO. Each peptide pull-down was performed on lysates from two biological replicates.

Project description:We used phosphoproteomics to compare the responses of the ERK1/2 inhibitors, SCH772984 and GDC0994, and the MKK1/2 inhibitor, trametinib. These are compared with responses to the MKK1/2 inhibitor, selumetinib (AZD6244), previously measured by our lab in the same metastatic melanoma cell line. In three replicate experiments, we quantified a total of 12,805 class I phosphosites on 3,819 proteins in the trametinib-SCH772984-DMSO experiment, and 7,074 class I phosphosites on 2,453 in the GDC0994-SCH772984-DMSO experiment. This included 466 phosphosites that reproducibly decreased in response to at least one inhibitor in the trametinib-SCH772984-DMSO experiment and 414 phosphosites in the GDC0994-SCH772984-DMSO experiment. The results demonstrate linearity in signaling through the MAP kinase pathway. By comparing multiple inhibitors targeted to multiple tiers of protein kinases in the MAPK pathway, we gain insight into regulation and new targets of the oncogenic BRAF driver pathway in cancer cells, and a useful approach for evaluating the specificity of drugs and drug candidates.
