Overall Abstract The overall goal of this SPORE in Myeloid Malignancies is to take advantage of our increased understanding of the genetic and molecular basis of acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) to develop novel, effective therapeutic strategies for patients with these treatment-resistant neoplasms. The extensive scientific and clinical resources at the Dana-Farber/Harvard Cancer Center (DF/HCC) will be leveraged – marshaling local expertise in cell and molecular biology, genetics, immunology, biostatistics, chemistry, murine models, and clinical trial development – in order to perform innovative pre-clinical studies, to validate novel drug targets in patient cells, and to design and implement clinical trials that will eventually lead to improved outcomes for patients with myeloid malignancies. Each of the four Projects will promote detailed analysis of a promising new target by a combination of pre-clinical studies to optimize therapeutic development and early-stage clinical trials. Project 1 leverages recent exciting data from the laboratory of Dr. Scott Armstrong regarding the efficacy of targeting the MLL-menin interaction, which is essential for maintaining HOXA expression and maintenance of leukemia stem cells. Project 2 is based on the discovery by the Stegmaier laboratory that many cases of AML are dependent on SYK kinase activation, and that SYK activation causes chemotherapy resistance. Project 3 will examine the pre-clinical and clinical efficacy of a novel SF3B1 inhibitor, using an Sf3b1-mutant model developed by the Ebert laboratory, for the treatment MDS. Project 4 will examine the potential synergy of a highly effective vaccine with a potent immunologic checkpoint inhibitor for the treatment of AML. The Cores have been designed to support all projects in translational research. The laboratory and clinical research components of each project will interface with Core 1 for statistical guidance in both experimental design and the interpretation of results. Core 2 will provide biospecimens banking for the samples produced by all projects in the course of clinical trials; these samples will be used for the generation of primagrafts in immunodeficient mice. Samples from the biospecimens bank as well as xenograft samples will, in turn, be available for use by the PI's of all projects. Core 3 will work with the clinical trials in each project for correlative studies. Ultimately, the proposed studies promise to improve the therapy of chemotherapy-resistant AML and splicing factor-mutant MDS, as well as developing an improved immunotherapeutic strategy for AML.

总体摘要 骨髓恶性肿瘤的SPORE的总体目标是利用我们对骨髓恶性肿瘤的了解， 急性髓性白血病（AML）和骨髓增生异常综合征（MDS）的遗传和分子基础， 为这些耐药肿瘤患者开发新的有效治疗策略。的 Dana-Farber/哈佛癌症中心（DF/HCC）的广泛科学和临床资源将 利用-汇集当地在细胞和分子生物学，遗传学，免疫学，生物统计学， 化学，小鼠模型和临床试验开发-为了进行创新的临床前研究， 在患者细胞中验证新的药物靶点，并设计和实施临床试验，最终导致 改善骨髓恶性肿瘤患者的预后。四个项目中的每一个都将促进详细的 通过结合临床前研究分析有前景的新靶点，以优化治疗开发 和早期临床试验。项目1利用了斯科特博士实验室最近的令人兴奋的数据。 阿姆斯特朗关于靶向MLL-menin相互作用的有效性，这对于维持 白血病干细胞的HOXA表达和维持。项目2是基于 Stegmaier实验室认为，许多AML病例依赖于SYK激酶的激活， 活化导致化疗抗性。项目3将研究一种新的抗肿瘤药物的临床前和临床疗效。 使用Ebert实验室开发的Sf 3b 1-突变体模型的新型SF 3B 1抑制剂，用于治疗MDS。 项目4将研究高效疫苗与有效免疫检查点的潜在协同作用 用于治疗AML的抑制剂。核心的设计是为了支持所有项目的翻译 research.每个项目的实验室和临床研究部分将与核心1接口， 在实验设计和结果解释方面的统计指导。核心2将提供 临床试验过程中所有项目产生的样本的生物样本库;这些样本 将用于在免疫缺陷小鼠中产生原核生物。生物标本库的样本 以及异种移植物样本将可供所有项目的PI使用。Core 3将与 每个项目的临床试验进行相关研究。最终，拟议中的研究有望改善 化疗耐药AML和剪接因子突变型MDS的治疗，以及开发一种 改善AML的免疫策略。
