项目摘要

The rearranged during transfection (RET) gene encodes a protein tyrosine kinase (PTK). RET aberrations are found in various types of human cancer. Highly potent and selective RET protein tyrosine kinase inhibitors (TKIs) are in the later stage of clinical development for precision cancer treatment. A lesson learned from the previous experience is that the PTK-targeted cancer therapy often fails because of adaptive resistance evolved from the drug-tolerant, residual tumors. Results of our preliminary studies indicate that the RET-targeted cancer treatment is no exception to this rule. To prolong the suppression of tumors and the lives of patients, we must eliminate the residual tumor cells, identify target mutations that cause drug resistance, find or develop drugs effective against different drug-resistant mutants, and discover alternative signaling mechanisms that promote tumor progression. The overall goal of this project is to improve the targeted therapy for RET aberration- associated cancer. The objectives of this project are to map the landscape of drug-resistant RET kinase mutations, identify drugs effective against mutant RET, determine the structures of RET kinase variants, characterize the structural bases of interaction between RET and its inhibitors, and evaluate a method to minimize the residual lung tumors. Specific Aim 1 is to identify and characterize RET mutations resistant to selective RET TKIs in preclinical models and cancer patients, and find potential secondary drugs. Specific Aim 2 is to determine the crystal structures of drug-resistant RET mutant proteins and RET-inhibitor complexes. Specific Aim 3 is to test RET mutant-sensitive TKIs in vivo and evaluate a method for reducing the residual fibrotic stroma and the associated residual tumor cells. Taken together, this study will provide a RET mutation- TKI toolkit for precision management of RET-aberrant cancers to maximize the benefit of RET-targeted cancer therapy, lay the foundation for developing a continuous pipeline of mutant-effective RET TKIs, and find a method to reduce the residual drug-tolerant tumors to delay tumor recurrence. The outcomes of this project will have positive translational impact on prolonging the survival of patients with cancer.

转染期间重排（RET）基因编码蛋白酪氨酸激酶（PTK）。保留畸变在各种类型的人类癌症中发现。高效和选择性RET蛋白酪氨酸激酶抑制剂（TKI）处于精确癌症治疗的临床发育的后期。从以前的经验是，以PTK为目标的癌症疗法经常因适应性抗性而失败来自耐药的残留肿瘤。我们的初步研究的结果表明，RET靶向癌症治疗也不例外。为了延长对肿瘤和患者的生命的抑制，我们必须消除残留的肿瘤细胞，识别引起耐药性的靶突变，发现或开发药物有效防止不同的耐药突变体，并发现促进的替代信号传导机制肿瘤进展。该项目的总体目标是改善针对RET像差的靶向疗法 - 相关癌症。该项目的目标是绘制耐药性RET激酶的景观突变，识别有效抗突变型的药物，确定RET激酶变异的结构，表征RET及其抑制剂之间相互作用的结构碱基，并评估一种方法最小化残留的肺肿瘤。具体目的1是识别和表征抗性的RET突变临床前模型和癌症患者的选择性RET TKI，并找到潜在的二次药物。具体目标 2是确定耐药的RET突变蛋白和RET抑制剂复合物的晶体结构。特定目标3是在体内测试对RET突变敏感的TKI，并评估一种减少残留的方法纤维化基质和相关的残留肿瘤细胞。综上所述，这项研究将提供RET突变 - TKI工具包用于精确管理重新捕获的癌症，以最大程度地利用靶向癌症的癌症的好处治疗，为开发突变有效的RET TKI的连续管道奠定基础，并找到一种方法减少残留药物耐受性肿瘤以延迟肿瘤复发。该项目的结果将有对延长癌症患者存活的积极翻译影响。
