Bead-based profiling of tyrosine kinase phosphorylation identifies SRC as a potential target for glioblastoma therapy.

Data from MASSIVE, [[http://proteomics.ucsd.edu/ProteoSAFe/datasets.jsp MSV000078499]]. File: K562_P060110_trypsin_09_19_ftt8_ccc_01.mzml. Published as part of Nat Biotechnol. 2009 Jan;27(1):77-83 . From the Abstract: {{i}} ... Here we describe a bead-based method for detecting phosphorylation of both wild-type and mutant tyrosine kinases in a multiplexed, high-throughput and low-cost manner. With the aim of establishing a tyrosine kinase-activation catalog, we used this method to profile 130 human cancer lines. Follow-up experiments on the finding that SRC is frequently phosphorylated in glioblastoma cell lines showed that SRC is also activated in primary glioblastoma patient samples and that the SRC inhibitor dasatinib (Sprycel) inhibits viability and cell migration in vitro and tumor growth in vivo ... {{/i}}
