项目摘要
DESCRIPTION (provided by applicant): The proposal addresses the potential of targeting the binding of DEPTOR to mTOR in TORC complexes in multiple myeloma cells. The preliminary results support the hypothesis that compounds can be identified in a yeast-hybrid high throughput screen that inhibit this binding. Once inhibited, we anticipate a subsequent dampening of the PI3-kinase/AKT pathway and induction of myeloma cell apoptosis. DEPTOR function is critical for survival of a subset of multiple myeloma clones consisting of approximately 30% of patients. This specific subset of patients can be identified by readily available clinical testing on their marrow malignant plasma cells. Thus, we part from the premise that identified compounds that inhibit DEPTOR-mTOR binding could be developed for effective targeted therapy for these patients. To further address DEPTOR as a therapeutic target, we will test the screening positive 'hits' for molecular effects in myeloma cells as well as anti-myeloma efficacy in vitro and in vivo in xenograft models.
描述(由申请方提供):该提案阐述了在多发性骨髓瘤细胞中靶向DEPTOR与TORC复合物中mTOR结合的潜力。初步结果支持的假设,化合物可以在酵母杂交高通量筛选,抑制这种结合。一旦被抑制,我们预期随后抑制PI 3-激酶/AKT通路并诱导骨髓瘤细胞凋亡。DEPTOR功能对于由大约30%的患者组成的多发性骨髓瘤克隆亚组的生存至关重要。这种特定的患者亚群可以通过对他们的骨髓恶性浆细胞进行现成的临床检测来鉴定。因此,我们的前提是,可以开发出抑制DEPTOR-mTOR结合的鉴定化合物,用于这些患者的有效靶向治疗。为了进一步说明DEPTOR作为治疗靶点,我们将测试筛选阳性“命中”在骨髓瘤细胞中的分子效应以及在异种移植模型中的体外和体内抗骨髓瘤功效。
