DESCRIPTION (provided by applicant): Cancer accounts for 8-9 million deaths a year, 80% of which are due to systemic spread of cancer to distant organs. It has long been recognized that primary cancers spread to distant organs with 'specific' preference, and skeleton/bone is one of the most common organs to be affected by metastatic cancer. Among primary cancers, prostate cancer is considered to be an orthotropic tumor with specific predilection to form bone metastasis. Over 70% of prostate cancer patients exhibit bone metastasis as detected during the disease course or autopsies. Prostate cancers are amongst the most commonly diagnosed malignancies and the 2nd leading cause of cancer death in men. Bone metastases are the predominant reason for prostate cancer related deaths, and current therapies have very short-term benefits, if any. To achieve the central objective, the laboratories of Kalluri, Pandolfi and Scadden have joined forces to propose a focused and cohesive plan to study the biology of bone metastasis. The three projects in this TMEN network will generate new genetic mouse models of metastatic prostate cancer, offer new insights into the biology of prostate cancer initiating cells, identify possible bone metastasis cell of origin, establish the role of tumor microenvironment in metastatic prostate cancer with specific emphasis on prostate and bone microenvironment, identify new therapeutic targets against metastatic prostate cancer and evaluate a new drugs for metastatic prostate cancer in pre-clinical trials. Successful completion of this proposed network proposal will offer significant new advances in area of metastatic prostate cancer.

描述(申请人提供)：癌症每年造成800-900万人死亡，其中80%是由于癌症全身扩散到远处器官造成的。长期以来，人们一直认为，原发癌症会以“特定的”偏好扩散到远处的器官，而骨骼/骨骼是最常见的受转移癌影响的器官之一。在原发癌中，前列腺癌被认为是一种具有特殊的骨转移倾向的正交性肿瘤。超过70%的前列腺癌患者在病程或尸检中发现有骨转移。前列腺癌是最常见的恶性肿瘤之一，也是男性癌症死亡的第二大原因。骨转移是前列腺癌相关死亡的主要原因，如果有的话，目前的治疗方法有非常短期的好处。为了实现这一中心目标，卡鲁里、潘多尔菲和斯卡登的实验室联合起来，提出了一个有重点和有凝聚力的计划，以研究骨转移的生物学。TMAN网络中的这三个项目将产生新的转移性前列腺癌小鼠模型，为前列腺癌起始细胞的生物学提供新的见解，鉴定可能的骨转移细胞来源，建立肿瘤微环境在转移性前列腺癌中的作用，重点关注前列腺癌和骨微环境，寻找针对转移性前列腺癌的新治疗靶点，并在临床前试验中评估转移性前列腺癌的新药。这项拟议的网络提案的成功完成将在转移性前列腺癌领域提供重大的新进展。
