DESCRIPTION (provided by applicant): This application for a K01 Mentored Career Development Award for Underrepresented Minorities is being submitted by Dr. Rukiyah Van Dross (Principal Investigator) and Dr. Jill C. Pelling (Sponsor). The application consists of two Phases for career development: Phase I (mentored, dependent) will consist of two-years of continuing postdoctoral supervision for Dr. Van Dross by Dr. Pelling, and Phase II (mentored, independent) consisting of 3 years of continued research by Dr. Van Dross in a more independent fashion as a research assistant professor in the Department of Pathology and Laboratory Medicine, but still working in space adjacent to Dr. Pelling's research laboratory with continued mentoring by Dr. Pelling. In Phase I Dr. Van Dross will work as a postdoctoral investigator in Dr. Pelling's laboratory, continuing to develop independent research skills in experimental design, data interpretation, manuscript/grant writing, graduate student/technician supervision, travel to scientific meetings and development of contacts with colleagues in the field of carcinogenesis and chemoprevention for purposes of establishing future research collaborations and developing a network of colleagues in the field who can advise Dr. Van Dross. The research project that Dr. Van Dross will work on during Phase I of her career development plan is presented in detail in this application, and is focused on specific aims to investigate the role of p38 MAP kinase in modulation of chemopreventive action by the bioflavonoid apigenin. This research project has been developed by Dr. Van Dross in consultation with Dr. Pelling, and its goals are clearly relevant to cancer biology and chemoprevention. The experimental approach proposed by Dr. Van Dross will extend her preliminary observations on apigenin induction of p38 MAP kinase and concomitant phosphorylation of p53 protein and apoptosis. The research proposed in this K01 application is separate from Dr. Pelling's NIH grant CA72987-05, entitled "Molecular mechanism of chemoprevention by apigenin," which focuses on induction of ERK by apigenin and downstream effects on p53 post-translational modification. In Phase II of the career development plan, Dr. Van Dross will be promoted to research assistant professor in the Department of Pathology and Laboratory Medicine (see Chairman's letter), assuming continued productivity toward research goals of the K01 grant. In Phase II Dr. Van Dross will continue to be mentored by Dr. Pelling in her research as well as in grant writing skills, manuscript writing, reviewing journal articles and professional contacts in her field. The research carried out by Dr. Van Dross during Phase II of her career development plan is outlined in detail in this application and will focus on investigating the protein/protein interactions of p38 MAP kinase and p53 and their role in apoptosis. The long-term goal of Dr. Van Dross' career development plan is to provide her with the skills to develop, establish and manage an independent externally-funded research program as a tenure-track faculty member at an academic medical center.

描述（由申请人提供）：本申请为代表性不足的少数民族K 01辅导职业发展奖是由Rukiyah货车德罗斯博士（主要研究员）和吉尔C博士提交。Pelling（申办方）。 该应用程序包括两个职业发展阶段：一期（指导，依赖）将包括两年的持续博士后监督博士货车Dross博士由博士佩林，和第二阶段（指导，独立）由货车Dross博士以更独立的方式作为病理学和实验室医学系的研究助理教授进行的3年持续研究组成，但仍在佩林博士的研究实验室附近的太空工作，继续接受佩林博士的指导。 在第一阶段，货车Dross博士将在Pelling博士的实验室担任博士后研究员，继续发展实验设计、数据解释、手稿/资助写作、研究生/技术人员监督、参加科学会议的差旅费，并与致癌和化学预防领域的同事建立联系，以建立未来的研究合作，并建立一个能给货车德罗斯医生提供建议的同行 货车Dross博士在其职业发展计划的第一阶段期间将从事的研究项目在本申请中详细介绍，并且集中于研究p38 MAP激酶在由芹菜素调节化学预防作用中的作用的具体目标。 该研究项目由货车Dross博士与Pelling博士共同开发，其目标显然与癌症生物学和化学预防相关。 货车Dross博士提出的实验方法将扩展她对芹菜素诱导p38 MAP激酶以及伴随的p53蛋白磷酸化和细胞凋亡的初步观察。 这项K 01申请中提出的研究与Pelling博士的NIH资助CA 72987 -05分开，该资助题为“芹菜素化学预防的分子机制”，其重点是芹菜素对ERK的诱导和对p53翻译后修饰的下游效应。 在职业发展计划的第二阶段，货车Dross博士将晋升为病理学和实验室医学系的研究助理教授（见主席的信），假设继续朝着K 01赠款的研究目标生产力。 在第二阶段，货车Dross博士将继续接受Pelling博士的指导，指导她的研究以及赠款写作技巧、手稿写作、审查期刊文章和她所在领域的专业联系。 货车Dross博士在其职业发展计划的第二阶段进行的研究在本申请中详细概述，并将重点研究p38 MAP激酶和p53的蛋白/蛋白相互作用及其在细胞凋亡中的作用。 货车Dross博士的职业发展计划的长期目标是为她提供技能，以开发，建立和管理一个独立的外部资助的研究计划，作为一个终身教职的教师在一个学术医疗中心。
