Title	Kinome profiling: cabozantinib treatment in a mouse model of plexiform neurofibroma
Description	Neurofibromatosis type 1 (NF1) is the most common autosomal dominant disorder, affecting 1 in 3,500 individuals worldwide and predisposing to cancer. Germline mutations in the NF1 gene, encoding the p21Ras GTPase-activating protein (GAP) neurofibromin, are the underlying cause for NF1. Somatic inactivation of the wild type copy of NF1 leads to deregulated Ras signaling. Clinical manifestations are diverse for NF1 patients, but the predominant lesions are plexiform neurofibroma (PNF), arising from the Schwann cell (SC) lineage. While PNF are generally benign, approximately 10% of patients will experience PN progression to highly aggressive malignant peripheral nerve sheath tumors (MPNST) with poor prognosis. There are currently no approved targeted therapies for PNF or MPNST. In this study, we used a conditional mouse model of NF1, test the multi-receptor tyrosine kinase inhibitor, cabozantinib (XL184). Mice were treated with vehicle or with cabozantinib for 3 or 7 days. Tissue was harvested, lysates prepared, and the lysate was used for kinome profiling. From cell lines or tumor tissue, protein lysates are prepared and passed over an affinity matrix consisting of Sepharose beads covalently coupled to a mixture of linker-adapted Type I kinase inhibitors. Kinase capture is reproducible and is a function of affinity for kinases for the immobilized inhibitors, expression level of the kinase, as well as the activation state of the kinase. Following affinity purification, kinases are identified and their multiplexed kinase inhibitor bead binding quantified by mass spectrometry (MIB/MS). Our goal is to identify the kinome changes in NF1 plexiform neurofibroma induced by cabozantinib treatment.
