项目摘要

PROJECT SUMMARY/ABSTRACT This K99/R00 award will prepare Dr. Genoa Warner for an independent research career, with the main goal of providing Dr. Warner with all the technical and profession skills necessary for her to become a successful independent investigator and leader in the field of reproductive toxicology. Dr. Warner has extensive training in endocrine disruption and sustainable chemistry and is currently a postdoctoral fellow in reproductive toxicology at the University of Illinois under the mentorship of Dr. Jodi A. Flaws. This award will enable Dr. Warner to expand her research training in reproductive biology and allow her to draw from her diverse scientific background in chemistry and biology to investigate important research questions in environmental health. These goals will be accomplished with the support of Dr. Warner's exceptional mentoring team, composed of Dr. Flaws, Dr. Susan Schantz, Dr. Heather Stapleton, and Dr. John Katzenellenbogen. The research proposal and career development plan created by Dr. Warner with the guidance of her mentoring team will provide Dr. Warner with new experimental techniques and skills needed to establish an independent research program. In the research training component of this proposal, Dr. Warner will investigate the mechanisms by which phthalates, a group of endocrine disrupting chemicals with ubiquitous human exposure, cause ovarian follicle toxicity. Further, she will investigate the metabolism of phthalates by ovarian tissue because phthalate metabolites mediate phthalate- inducted toxic effects, contributing to infertility and premature ovarian failure. In the prosed studies, Dr. Warner will use environmentally relevant concentrations of six phthalates as a mixture and individually. Specific Aim 1 (mentored phase) will identify how phthalates partition into ovarian tissue during culture via mass spectrometry and imaging methods using chemically modified phthalates. Specific Aim 2 (mentored and independent phases) will determine how phthalate toxicity varies between cell types of the ovary by culturing populations of each cell type found in the ovarian follicle with phthalates. Finally, Specific Aim 3 (Independent Phase) will identify the genomic localization of phthalates in the ovary by adapting the biochemical technique of chemical affinity capture paired with massively parallel DNA sequencing (Chem-seq) to provide information on the genes and proteins targeted by phthalates. Overall, the proposed studies will provide novel chemical and mechanistic insight into causes of phthalate-induced toxicity in the ovary that contribute to female infertility and premature ovarian failure. The methods combine chemical and biological techniques to develop a new, widely applicable technology for investigating the mechanisms of endocrine disrupting chemicals that will provide the basis for Dr. Warner's independent career.
项目总结/摘要 这个K99/R 00奖项将为热那亚华纳博士的独立研究生涯做好准备,其主要目标是 为华纳博士提供所有必要的技术和专业技能,使她成为一个成功的 生殖毒理学领域的独立研究者和领导者。华纳博士受过广泛的训练, 目前是生殖毒理学博士后研究员 在伊利诺伊大学的乔迪博士的指导下,缺点这个奖项将使华纳博士能够扩大 她在生殖生物学方面的研究训练,使她能够从她多样化的科学背景中汲取经验, 化学和生物学研究环境健康的重要研究问题。这些目标将是 在华纳博士杰出的指导团队的支持下完成,该团队由Flaws博士,Susan博士, 尚茨,石楠斯台普顿博士,和约翰·卡岑伦伯根博士。研究计划和职业生涯 华纳博士在其指导团队的指导下制定的发展计划将为华纳博士提供 建立独立研究计划所需的新实验技术和技能。研究中 培训部分,华纳博士将调查邻苯二甲酸酯,一组 内分泌干扰物与人体普遍接触,引起卵巢卵泡毒性。此外,她将 研究邻苯二甲酸酯通过卵巢组织的代谢,因为邻苯二甲酸酯代谢物介导邻苯二甲酸酯- 诱发毒性作用,导致不孕和卵巢早衰。在所进行的研究中,华纳博士 将使用环境相关浓度的六种邻苯二甲酸盐作为混合物和单独使用。具体目标1 (指导阶段)将通过质谱法确定培养期间邻苯二甲酸酯如何分配到卵巢组织中 以及使用化学改性邻苯二甲酸酯的成像方法。具体目标2(辅导阶段和独立阶段) 将通过培养每种细胞的群体来确定邻苯二甲酸酯毒性在卵巢细胞类型之间的变化 在卵巢卵泡中发现的邻苯二甲酸盐。最后,具体目标3(独立阶段)将确定 采用化学亲和捕获生化技术对卵巢中邻苯二甲酸酯的基因组定位 与大规模并行DNA测序(Chem-seq)配对,以提供基因和蛋白质的信息 邻苯二甲酸盐的目标总的来说,拟议的研究将提供新的化学和机制的见解, 邻苯二甲酸酯引起卵巢毒性的原因,导致女性不孕和卵巢早衰。 该方法将联合收割机化学和生物技术相结合,以开发一种新的、广泛适用的技术, 研究内分泌干扰化学物质的机制,这将为华纳博士的研究提供基础。 独立的职业生涯。
