项目摘要

DESCRIPTION (provided by applicant): This BRP application aims to establish a highly collaborative and multidisciplinary cancer nanotechnology program by integrating the bioengineering strengths of Georgia Tech (Atlanta, GA), the spectral imaging expertise of CSRI (Woburn, MA), and the cancer biology and clinical oncology experiences of Emory University School of Medicine (Urology, Pathology, Radiation Oncology, Winship Cancer Institute, and the VA Hospital, Atlanta, GA). With faculty participation from eight science, engineering, and clinical departments, and advised by a prominent Scientific Advisory Board (SAB), this Partnership incorporates broad expertise in bioengineering, bioinformatics, tumor biology, bioanalytical chemistry, systems biology, hematology / oncology, pathology, and urology. Its broad and long-term goal is to develop biomedical nanotechnology, biomolecular engineering, and bioinformatics tools for linking molecular signatures (biomarkers) of cancer and the host microenvironment with cancer behavior and clinical outcome. The proposed research is broadly applicable to many types of malignant tumors such as breast cancer, colorectal carcinoma, and lymphoma, but a particular focus will be placed on the biological behavior of human prostate cancer and its clinically lethal phenotypes. A compelling reason for this focus is that prostate cancer presents a number of unique challenges and opportunities in human oncology. Its widespread occurrence (about 220,000 new cases this year in the US), tendency for a long natural history, highly heterogeneous and multi-focal histopathology, and progression to hormone independence are still poorly understood. Faced with this reality, we propose to develop advanced nanoparticle technologies (e.g., molecular beacons, semiconductor quantum dots, and enhanced Raman probes) for ultrasensitive and multiplexed profiling of biomarkers on intact cancer cells or tissue specimens. In contrast to current molecular-profiling technologies, the use of encoded nanoparticle probes allows a seamless integration of traditional pathology and cancer biology with sensitive molecular analysis, a central theme that runs across the entire proposed research. Underlying this BRP is a strong track record of the senior investigators who have worked together successfully in attracting joint research grants. In addition, the Department of Biomedical Engineering, which was jointly established in 1997 by Georgia Tech and Emory University, has presented an unusual opportunity for research collaboration to bring bioengineering technologies and discoveries into medicine and vice versa. If funded, this cancer nanotechnology program will be housed in the Winship Cancer Institute, a new 280,000 sq ft cancer research and care building located on the Emory Campus and with a truly outstanding environment for collaborative and translational cancer research. In additional to basic knowledge on cancer biology and biomarkers, this Partnership is expected to yield at least three practical outcomes: (a) a database linking molecular signatures with cancer biology and clinical outcome, (b) bioconjugated nanoparticles for molecular profiling of cancer, and (c) muiltiplexed spectral imaging microscopes and software.

描述（申请人提供）：此BRP应用程序旨在通过整合格鲁吉亚技术的生物工程优势，建立一个高度协作和多学科的癌症纳米技术计划（亚特兰大，GA），CSRI的光谱成像专业知识（Woburn，MA），以及埃默里大学医学院的癌症生物学和临床肿瘤学经验。（泌尿科、病理学、放射肿瘤学、Winship癌症研究所和VA医院，亚特兰大，GA）。随着来自八个科学，工程和临床部门的教师参与，并由一个著名的科学顾问委员会（SAB）的建议，这种伙伴关系结合了生物工程，生物信息学，肿瘤生物学，生物分析化学，系统生物学，血液学/肿瘤学，病理学和泌尿学的广泛专业知识。其广泛和长期的目标是开发生物医学纳米技术，生物分子工程和生物信息学工具，用于将癌症和宿主微环境的分子特征（生物标志物）与癌症行为和临床结果联系起来。拟议的研究广泛适用于多种类型的恶性肿瘤，如乳腺癌、结直肠癌和淋巴瘤，但将特别关注人类前列腺癌的生物学行为及其临床致命表型。这种关注的一个令人信服的原因是前列腺癌在人类肿瘤学中提出了许多独特的挑战和机遇。它的广泛发生（今年在美国约有220，000例新发病例），长期自然史的趋势，高度异质性和多灶性组织病理学，以及激素依赖性的进展仍然知之甚少。面对这一现实，我们建议开发先进的纳米颗粒技术（例如，分子信标、半导体量子点和增强型拉曼探针），用于对完整癌细胞或组织样本上的生物标志物进行超灵敏和多重分析。与目前的分子分析技术相比，编码纳米粒子探针的使用允许传统病理学和癌症生物学与敏感分子分析的无缝集成，这是贯穿整个拟议研究的中心主题。这一BRP的基础是一个强大的跟踪记录的高级研究人员谁一起工作，成功地吸引了联合研究赠款。此外，由格鲁吉亚理工学院和埃默里大学于1997年联合成立的生物医学工程系为研究合作提供了一个不同寻常的机会，将生物工程技术和发现带入医学，反之亦然。如果获得资助，这个癌症纳米技术项目将被安置在温希普癌症研究所，这是一个新的280，000平方英尺的癌症研究和护理大楼，位于埃默里校区，为合作和转化癌症研究提供了真正出色的环境。除了关于癌症生物学和生物标志物的基本知识外，该伙伴关系预计将产生至少三个实际成果：（a）将分子特征与癌症生物学和临床结果联系起来的数据库，（B）用于癌症分子特征分析的生物缀合纳米颗粒，以及（c）多重光谱成像显微镜和软件。
