项目摘要

DESCRIPTION (provided by applicant): The objective for this research is to develop a new form of microscopy, Surface Plasmon Enhanced Microscopy (SPEM). SPEM achieves resolution of 35 nm and is intended to be used for localization of multiple proteins in cells and determine molecular signatures of patients? tumors. The SPEM system generates a database of protein locations within a cell referenced to the position of cellular features (e.g., cell and nuclear membranes, organelles). SPEM can be used to identify molecular signatures of cancer based on protein expression levels and locations. Over time it is expected that a database of SPEM images will be assembled that will serve as a reference for the diagnosis of cancer at the molecular level. SPEM has been designed to seamlessly integrate into the clinical pathology laboratory. The steps required to implement a SPEM analysis are: (1) stain the slide (2) the pathologist reads the slide and marks cells for which a molecular analysis (using a digital coordinate system that is incorporated into the SPEM microscope) is desired (3) SPEM automatically generates the localization and expression level data for the marked cells, and (4) the pathologist analyzes the results in conjunction with the existing immunohistochemical and morphological data to determine the patients? prognoses and select the appropriate therapy. In the R21 research the optical performance of the system will be characterized and the applicability to paraffin-embedded tissue specimens will be demonstrated. In the R33 research the full microscope will be develop and used to generate protein localization and expression data for multiple proteins in a tissue sample.

描述（由申请人提供）：这项研究的目的是开发一种新的显微镜，表面等离子体增强显微镜（SPEM）。SPEM的分辨率达到35 nm 并且旨在用于细胞中多种蛋白质的定位，确定病人的分子特征肿瘤的SPEM系统生成细胞内蛋白质位置的数据库，蜂窝特征（例如，细胞和核膜，细胞器）。SPEM可以是用于基于蛋白质表达识别癌症的分子特征水平和位置。随着时间的推移，预计SPEM图像数据库将作为癌症诊断的参考在分子水平上。SPEM旨在无缝集成到临床病理学实验室实施SPEM所需的步骤分析是：（1）染色载玻片（2）病理学家读取载玻片，标记分子分析（使用数字坐标系）所针对的细胞（3）SPEM显微镜自动生成的定位和表达水平的数据，标记的细胞，以及（4）病理学家结合现有的免疫组织化学和形态学数据，以确定病人？诊断并选择适当的治疗方法。在R21研究中，将表征系统的光学性能，将证明对石蜡包埋组织标本的适用性。在 R33研究将开发全显微镜，组织中多种蛋白质的蛋白质定位和表达数据 sample.
