Pathophysiologies Involving Hemostasis related Genes

项目摘要

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.

越来越清楚的是，传统上与止血作用相关的基因在许多其他不同的病理生理过程中。例子是与纤维蛋白溶解有关的基因产物的参与，例如纤溶酶原，纤溶酶原激活剂和纤溶酶原激活剂抑制剂，以及它们在癌症，伤口愈合和血管生成中的作用。这些相同的基因以及与凝血相关的基因产物，例如组织因子和抗凝凝集，例如蛋白C，在胚胎发生，癌症以及急性和基于慢性炎症的过程等中也起作用。因此，与止血有关的基因是健康和疾病中不同途径之间的联系。该计划项目赠款（PPG）建立在现有优势的基础上，并整合经验丰富的研究人员的研究工作，这些研究人员对我们对蛋白质化学，分子和细胞生物学，基因靶向以及与止血有关的蛋白质和基因的病理学作用做出了重大贡献。该PPG的重点是与止血相关基因的体内作用的定义：在败血症进展过程中（Castellino Project by castellino），在血管内凝血，全身性炎症和器官损伤之间的关系之间的关系；肿瘤发生，转移和血管生成（Ploplis的Project）；以及后代的胚胎和围产期生存，以及体内血栓形成（Rosen的项目）。提出了三个核心单位中央支持这组项目：（1）行政核心，（2）解剖病理学核心，以及（3）小鼠育种和饲养核心。该项目和核心领导者相互相互作用的历史悠久，并且都基于致力于体内和体外研究的基础设施富含基础设施的中心。提出的项目将利用相同的管理，组织病理学和鼠标核心。 PPG将使项目负责人在研究与止血相关基因的功能作用的实验室之间进行增加的相互作用和协作，而这些综合努力产生的总体程序将超过各个部分的总和。学生和博士后的研究工作和生产力将从PPG产生的单个实验室和核心的互动中受益匪浅，并将作为在这些研究领域进行连续独立研究的资源。
