Pathophysiologies Involving Hemostasis-related Genes

越来越清楚的是，传统上与止血相关的基因在许多其他不同的病理生理过程中发挥作用。例如，与纤溶有关的基因产物，如纤溶酶原、纤溶酶原激活剂和纤溶酶原激活剂抑制物，及其在癌症、伤口愈合和血管生成中的作用。这些基因以及与凝血相关的基因(如组织因子)和抗凝血素(如蛋白C)的产物也在胚胎发生、癌症以及基于急性和慢性炎症的过程中发挥作用。因此，止血相关基因在健康和疾病的不同途径之间起着联系作用。该计划项目赠款(PPG)建立在现有优势的基础上，并整合了经验丰富的研究人员的研究努力，他们为我们理解蛋白质化学、分子和细胞生物学、基因靶向以及与止血相关的蛋白质和基因的病理生理学做出了重大贡献。PPG的重点是止血相关基因在体内的作用的定义：弥散性血管内凝血、全身炎症和脓毒症进展过程中器官损害之间的关系(Castellino项目)；肿瘤发生、转移和血管生成(Ploplis项目)；以及后代的胚胎和围产期存活以及体内血栓形成(Rosen项目)。根据需要提出了三个核心单位，以 集中支持这组项目：(1)行政核心，(2)解剖病理学核心，和(3)老鼠饲养和畜牧业核心。项目和核心领导者之间有着长期的富有成效的互动历史，他们都以一个基础设施丰富的中心为基础，致力于体内和体外凝血、抗凝和纤溶的研究。提议的项目将使用相同的管理、组织病理学和鼠标核心。PPG将允许项目负责人的实验室在研究止血相关基因的功能作用方面加强互动和合作，这些联合努力产生的整体计划将超过各个部分的总和。学生和博士后的研究努力和生产力将极大地受益于各个实验室和核心之间的互动，这将导致PPG，并将 作为在这些研究领域持续开展独立调查的资源。

It is becoming increasingly clear that genes traditionally associated with hemostasis function in many other diverse pathophysiologic processes. Examples are the involvement of gene products related to fibrinolysis, e.g., plasminogen, plasminogen activators, and plasminogen activator inhibitors, with their roles in cancer, wound healing, and angiogenesis. These same genes, as well as products of genes of relevance to coagulation, e.g., Tissue Factor, and anticoagulation, e.g., Protein C, also function in embryogenesis, cancer, and acute and chronic inflammatory-based processes, among others. Thus, hemostasis-related genes serve as links between different pathways in health and disease. This Program Project Grant (PPG) builds on existing strengths and integrates the research efforts of experienced investigators who have made major contributions to our understanding of the protein chemistry, molecular and cell biology, gene targeting, and pathophysioiogies of proteins and genes associated with hemostasis. The focus of this PPG is the definition of the in vivo roles of hemostasis-related genes in: the relationships between disseminated intravascular coagulation, systemic inflammation, and organ damage during the progression of sepsis (Project by Castellino); tumorigenesis, metastasis, and angiogenesis (Project by Ploplis); and embryonic and perinatal survival of offspring, as well as in vivo thrombus formation (Project by Rosen). Three core units are proposed as necessary to centrally support this group of projects: (1) an Administrative Core, (2) an Anatomic Pathology Core, and (3) a Mouse Breeding and Husbandry Core. The Project and Core Leaders have a long history of productive interactions with each other and are all based in an infrastructure-rich center devoted to in vivo and in vitro studies of coagulation, anticoagulation, and fibrinolysis. The projects proposed will utilize the same administrative, histopathology, and mouse cores. The PPG will allow increased interactions and collaborations to occur between the laboratories of the Project Leaders in studying the functional roles of hemostasis-related genes, and the overall program that results from these combined efforts will exceed the sum of the individual parts. The research efforts and productivity of students and postdoctorals will benefit greatly from the interactions of the individual laboratories and cores that will result from the PPG, and will serve as a resource for a continual flow of independent investigations in these research areas.
