项目摘要

DESCRIPTION (provided by applicant): This application for a K23 Mentored Patient-Oriented Research Career Development Award includes a 5-year plan for training and research activities that will provide the skills and experience needed to achieve success as an independent investigator studying the role of the environment and epigenetic mechanisms in birth outcomes. The candidate has completed research and clinical fellowships that prepared her for an academic career studying perinatal social epidemiology and is currently a full-time faculty member in the Department of Neonatology at Beth Israel Deaconess Medical Center. The candidate is a core member of the Division of Newborn Medicine at Harvard Medical School serving as an Instructor in pediatrics, which is the standard entry level academic position at Harvard. This K23 award will provide her with the structure and support necessary to accomplish the following goals: (1) assess the role that arsenic plays in fetal growth; (2) assess the role arsenic plays in the DNA methylation of genes involved in fetal growth such as inflammatory cytokine genes and the glucocorticoid receptor gene, and explore whether arsenic affects fetal growth through such epigenetic mechanisms; (3) gain expertise in environmental toxicology and environmental epigenetic analyses; and (4) learn the administrative skills needed to manage a large cohort study so that transition to an independent research career running her own birth cohort is accomplished. The candidate's goal is to examine the role the toxic chemical environment plays in birth outcome disparities in the US. To achieve these goals, Dr. Burris has assembled a mentoring team comprised of a primary mentor, Robert Wright, MD MPH, Associate Professor of Pediatrics and Environmental Health who is an expert in pediatric environmental health and toxicology, and co-mentor Andrea Baccarelli, MD PhD, the Mark and Catherine Winkler Associate Professor of Environmental Epigenetics, who has expertise in epigenetic analyses. Although chemicals like arsenic are known to affect birth outcomes and known to affect DNA methylation, it remains unknown whether DNA methylation mediates arsenic-birth weight associations. The study proposed is designed to test the hypothesis that arsenic impairs fetal growth, that arsenic causes alterations in the DNA methylation of inflammatory cytokine genes and the glucocorticoid receptor gene. The candidate will explore whether DNA methylation disturbances mediate arsenic-birth weight associations. These analyses will be performed within a previously established, currently funded cohort in Mexico City (ELEMENT) directed by Dr. Wright. The candidate will use the abundant resources available at Beth Israel Deaconess Medical Center, the Harvard Catalyst (Clinical and Translational Science Center) and the Harvard School of Public Health to obtain the training and coursework necessary to supplement the practical training attained through these analyses to become an independent investigator with a research program studying the environmental impact on birth outcome disparities.
描述(由申请人提供):这份 K23 指导性患者导向研究职业发展奖申请包括一项为期 5 年的培训和研究活动计划,该计划将提供作为一名独立研究者取得成功所需的技能和经验,研究环境和表观遗传机制在出生结果中的作用。该候选人已完成研究和临床奖学金,为她从事围产期社会流行病学的学术生涯做好准备,目前是贝斯以色列女执事医疗中心新生儿科的全职教员。该候选人是哈佛医学院新生儿医学部的核心成员,担任儿科讲师,这是哈佛的标准入门级学术职位。该 K23 奖项将为她提供实现以下目标所需的结构和支持:(1)评估砷在胎儿生长中的作用; (2)评估砷在炎症细胞因子基因、糖皮质激素受体基因等胎儿生长相关基因DNA甲基化中的作用,探讨砷是否通过这种表观遗传机制影响胎儿生长; (3) 获得环境毒理学和环境表观遗传分析方面的专业知识; (4) 学习管理大型队列研究所需的管理技能,以便完成向管理自己的出生队列的独立研究职业的过渡。候选人的目标是研究有毒化学环境在美国出生结果差异中所扮演的角色。为了实现这些目标,Burris 博士组建了一个指导团队,由首席导师 Robert Wright(医学博士、公共卫生硕士、儿科环境健康和毒理学专家、儿科和环境健康副教授)和共同导师 Andrea Baccarelli(医学博士、Mark 和 Catherine Winkler 环境表观遗传学副教授、表观遗传学专业知识)组成。 分析。尽管已知砷等化学物质会影响出生结果并影响 DNA 甲基化,但 DNA 甲基化是否介导砷与出生体重的关联仍不清楚。这项研究旨在检验以下假设:砷会损害胎儿生长,砷会导致炎症细胞因子基因和糖皮质激素受体基因的 DNA 甲基化发生改变。候选人将探讨 DNA 甲基化紊乱是否介导砷与出生体重的关联。这些分析将在 Wright 博士指导下的先前在墨西哥城建立、目前资助的队列 (ELEMENT) 中进行。候选人将利用贝斯以色列女执事医疗中心、哈佛催化剂(临床和转化科学中心)和哈佛公共卫生学院的丰富资源,获得必要的培训和课程,以补充通过这些分析获得的实践培训,成为一名独立调查员,负责研究环境对出生结果差异影响的研究项目。
