项目摘要

DESCRIPTION (provided by applicant): The overall goal of this award is to provide a mentored research environment so that the candidate can develop into an independent investigator in the field of gastric cancer induced by Helicobacter pylori infection. The candidate is currently receiving postdoctoral training support under an NIH Research Supplement for Underrepresented Minorities, working on the inflammatory response to H. pylori infection of the gastric mucosa. This award will allow the candidate to develop a related but independent project on the role of the immune response to H. pylori in the development of gastric cancer. The candidate has received extensive training in animal models of infection and the molecular analysis of inflammatory mediators. The immediate career goal is to initiate the proposed work that builds on previous training and expertise but that moves in a new direction relevant to gastric cancer. The long-term career goal is to obtain independent funding for this project and to secure a faculty-level academic appointment. These goals will be achieved by mentoring from two senior investigators with extensive experience in research training and in the proposed area of study. Career development will be enhanced by a close but progressively independent scientific relationship with the mentors. The full resources of the UCSD Cancer Center will be used by the candidate. Increasing independence will be achieved by presentations at scientific meetings, critical reviews, publication of work, and grant submissions in later years. The research project is formulated to develop an independent line of investigation that is based on the previous and current work of the candidate. H. pylori infects the gastric mucosa, leading to peptic ulcers and a high risk of gastric cancer. The central hypothesis of this proposal is that H. pylori-induced immune response dysregulates gastric epithelial cell turnover, resulting in carcinogenesis. The candidate has developed mouse and cell culture models of H. pylori infection and will use these to determine the roles of inflammatory mediators in gastric epithelial cell apoptosis and in the regulation of cell proliferation. Under this award, the candidate will be able to develop this work into a productive project that will gain independent funding.

描述（由申请人提供）：该奖项的总体目标是提供一个指导性的研究环境，使候选人能够发展成为幽门螺杆菌感染引起的胃癌领域的独立研究者。这位候选人目前正在接受美国国立卫生研究院为代表性不足的少数民族提供的博士后培训支持，研究对H.胃粘膜的幽门感染。该奖项将允许候选人开发一个相关但独立的项目，对H的免疫反应的作用。幽门螺杆菌在胃癌发生中的作用候选人在感染的动物模型和炎症介质的分子分析方面接受了广泛的培训。近期的职业目标是启动拟议的工作，建立在以前的培训和专业知识，但在一个新的方向移动相关胃癌。长期的职业目标是为这个项目获得独立的资金，并确保一个学院级的学术任命。这些目标将通过两名在研究培训和拟议研究领域具有丰富经验的高级研究人员的指导来实现。职业发展将通过与导师建立密切但逐步独立的科学关系来加强。 UCSD癌症中心的全部资源将由候选人使用。通过在科学会议上的演讲，批判性评论，出版工作和以后的拨款申请，将实现越来越多的独立性。该研究项目是制定一个独立的调查线，是基于候选人以前和目前的工作。 H.幽门螺杆菌感染胃粘膜，导致消化性溃疡和胃癌的高风险。这个建议的中心假设是H。幽门诱导的免疫应答失调胃上皮细胞更新，导致癌变。候选人已经开发了H的小鼠和细胞培养模型。pylori感染，并将使用这些来确定炎症介质在胃上皮细胞凋亡和细胞增殖调节中的作用。在这个奖项下，候选人将能够将这项工作发展成为一个富有成效的项目，将获得独立的资金。
