    • Provided are over 300 mTOR kinase targets identified by a comprehensive phosphoproteomics assay. Methods of targeting mTOR kinase targets, methods to determine the level of mTOR activity by measuring the level of phosphorylation of an mTOR targeted phosphorylation site, methods for distinguishing different classes of mTOR activity in a cell based on phosphoproteomic analysis of mTOR-targeted proteins are also provided. Also provided is the classification of a hyperproliferative disease based on phosphoproteomic analysis of mTOR-targeted proteins, as well as the personalization of therapeutic methods for the treatment of hyperproliferative disease based on phosphoproteomics. Also provided are therapeutic methods including administering to a subject an mTOR inhibitor, an mTOR inhibitor and an additional kinase inhibitor, or a dual inhibitor of mTOR and an additional kinase based on the phosphorylation levels of mTOR targets determined in the subject. Some aspects of this invention relate to the discovery that GrblO is an mTOR-targeted tumor suppressor gene.
    • 提供了通过综合磷酸化蛋白质测定法鉴定的超过300个mTOR激酶靶标。 靶向mTOR激酶靶标的方法,通过测量mTOR靶向磷酸化位点的磷酸化水平来测定mTOR活性水平的方法,基于mTOR靶向蛋白质的磷酸化蛋白质分析来区分细胞中不同种类的mTOR活性的方法也是 提供。 还提供了基于mTOR靶向蛋白质的磷酸化蛋白质组学分析的过度增殖性疾病的分类,以及基于磷酸化蛋白质处理过度增殖性疾病的治疗方法的个性化。 还提供了治疗方法,包括向受试者施用mTOR抑制剂,mTOR抑制剂和另外的激酶抑制剂,或mTOR的双重抑制剂和基于受试者确定的mTOR靶标的磷酸化水平的另外的激酶。 本发明的一些方面涉及GrblO是mTOR靶向的肿瘤抑制基因的发现。
