项目摘要

The broad focus of this project is to understand the molecular mechanisms underlying the effects of the tumor microenviroment on endothelial function and the effects of specific tumor-induced endothelial cell proteins on tumor growth, progression and angiogenesis. Such basic information is essential to develop new diagnostic and therapeutic strategies that may prove useful in improving the early detection and treatment of solid t umors. W e w ill focus p rimarily one haracterizing our new tumor-induced, endothelial and caveolar target, an AnnAl related protein, identified through our proteomic analysis of tumor luminal endothelial cell membranes. We will define the specific nature and function of this protein as well as use our panel of specific antibodies to this new target protein to evaluate expression and function in the context of solid tumors and its endothelium. To this end, we will address the following specific aims: 1. To determine the role of the tumor cell and tissue host environment, including specific angiogenic factors, on its expression, translocation, and externalization in caveolae. 2. To investigate the role of its expression by the tumor endothelium on endothelial cell function, solid tumor growth, and angiogenesis. We will use various rat and mouse tumor model systems as well as multiple biochemical and microscopic methodologies to examine in vivo and in cell culture the function of specific expression in caveolae. For instance, the potential anti-tumor effects of naked antibodies blocking possible protein function will be assessed. With this information, we plan to develop the means to improve the detection and staging of solid tumors as well as elaborate novel strategies for more effective and less toxic anti-cancer treatments.

该项目的广泛重点是了解肿瘤微病毒对内皮功能的影响的分子机制以及特定肿瘤诱导的内皮细胞蛋白对肿瘤生长，进展和血管生成的影响。这样的基本信息对于开发新的诊断和治疗策略至关重要，这些策略可能被证明可用于改善固体T肌的早期检测和治疗。通过我们对新的肿瘤诱导的内皮和洞穴靶标的焦点，这是一种刺激性的，这是一种环状相关蛋白膜。我们将定义该蛋白质的特定性质和功能，并使用与该新靶蛋白的特定抗体面板一起评估实体瘤及其内皮的背景下的表达和功能。为此，我们将解决以下特定目的：1。确定肿瘤细胞和组织宿主环境的作用，包括特定的血管生成因子，在小窝中其表达，易位和外部化。 2。研究其表达通过肿瘤内皮对内皮细胞功能，实体瘤生长和血管生成的作用。我们将使用各种大鼠和小鼠肿瘤模型系统以及多种生化和微观方法学来检查体内和细胞中培养口腔中特定表达的功能。例如，将评估裸抗体的潜在抗肿瘤效应可能会评估可能的蛋白质功能。有了这些信息，我们计划开发一种方法来改善实体瘤的检测和分期，并制定新的新型策略，以进行更有效和毒性的抗癌治疗。
