DESCRIPTION (provided by applicant): The Program Project Grant "Targeting diet-induced promotion of Kras-initiated pancreatic adenocarcinoma" constitutes a highly collaborative, multidisciplinary research program designed to make a significant impact on the investigation of diet in the development of pancreatic cancer. A detailed understanding of the biological mechanisms of action of a typical Western-style diet, rich in fats and calories, on pancreatic cancer development can form the rationale for biologically-based practices and scientifically-founded dietary recommendations in the prevention of this disease. Our Program Project includes expertise from the UCLA campus and VA Greater Los Angeles Healthcare System - West Los Angeles (VAGLAHS-WLA). The Program is led by experienced pancreatic cancer researchers, who have organized investigative teams to develop highly interactive and synergistic research programs. Our goal is to study the mechanisms, by which a Western-style diet, rich in fats and calories, promotes pancreatic cancer development and to explore interventional, cancer-preventing strategies. Innovative animal and cell culture models and novel concepts strongly supported by a wealth of preliminary data are proposed. The Projects will focus on: Inflammatory processes in diet-induced pancreatic cancer promotion (Project 1); Chemoprevention of pancreatic cancer with antidiabetic agents (Project 2); Inefficient autophagy, mitochondrial dysfunction, and pancreatic tumorigenesis (Project 3); Alcohol abuse and metabolic syndrome promote desmoplasia of pancreatic cancer (Project 4). The projects will utilize our Shared Core Resources including the Administrative Core (with Biostatistics Sub-Core) and the Animal Core (with Pathology Sub-Core). An External Advisory Board comprised of nationally and internationally recognized translational pancreatic cancer investigators and advocates has been assembled. The Program Project is designed for maximum integration and synergy of research and key investigators, who have been collaborating over the years so that the proposed Program can be focused on the most promising investigations with the greatest translational potential and impact.

项目描述（由申请人提供）：“针对饮食诱导的kras引发的胰腺腺癌的促进”是一个高度协作的多学科研究项目，旨在对饮食在胰腺癌发展中的研究产生重大影响。详细了解富含脂肪和卡路里的典型西式饮食对胰腺癌发展的生物学机制，可以为预防这种疾病的生物学基础实践和科学基础饮食建议提供依据。我们的项目项目包括来自加州大学洛杉矶分校和VA大洛杉矶医疗保健系统-西洛杉矶（VAGLAHS-WLA）的专业知识。该项目由经验丰富的胰腺癌研究人员领导，他们组织了调查团队，开发了高度互动和协同的研究项目。我们的目标是研究富含脂肪和卡路里的西式饮食促进胰腺癌发展的机制，并探索介入性癌症预防策略。创新的动物和细胞培养模型和新概念强有力地支持了丰富的初步数据提出。该项目将重点关注：饮食诱导胰腺癌促进中的炎症过程（项目1）；降糖药对胰腺癌的化学预防作用（项目二）；低效率自噬、线粒体功能障碍和胰腺肿瘤发生（项目3）；酒精滥用和代谢综合征促进胰腺癌的结缔组织增生（项目4）。这些项目将利用我们的共享核心资源，包括行政核心（生物统计学分核心）和动物核心（病理学分核心）。由国内和国际公认的转化胰腺癌研究人员和倡导者组成的外部咨询委员会已经成立。该项目旨在最大限度地整合和协同研究和主要研究人员，他们多年来一直在合作，以便拟议的项目可以专注于最有前途的研究，具有最大的转化潜力和影响。
