项目摘要
PROJECT SUMMARY/ABSTRACT
Background: The increasing incidence and prevalence of type 2 diabetes (T2D) can be mitigated by
successful prevention with behavioral changes or pharmacotherapy in individuals that are at high risk.
Identifying a specific individual’s risk for diabetes and which preventive treatment will be most effective,
however, remains a clinical dilemma. Metabolite biomarkers represent a novel approach to addressing these
clinical challenges and may also reveal mechanisms of disease development. This five-year mentored career
development proposal details a translational research training program in biomarker discovery and clinical
study implementation with a goal of identifying metabolite predictors of diabetes and preventive treatment
effect. Candidate: The applicant is a recently appointed Endocrinology faculty member at Beth Israel
Deaconess Medical Center with a long-term goal to become a physician-scientist who investigates metabolic
pathways involved in T2D development and progression. She has 2.5 years of experience in molecular
profiling in large human studies and the outlined proposal builds on this background to provide new domains of
expertise including prediction modeling, genetics, and clinical study design. Training: The applicant’s
development will occur through a blend of laboratory training, didactic courses (including an ongoing MPH),
and scientific conferences. The candidate’s mentor is a recognized leader in molecular profiling, integrative
“omics”, and cardiometabolic diseases. Her co-mentor is a leader in T2D genetics, and the members of her
advisory committee have a distinguished mentoring record and vast expertise in T2D, non-targeted
metabolomics, statistical modeling, and clinical trials. Research: Recently, the applicant identified unique
metabolite profiles associated with T2D in a large, randomized control trial that compared lifestyle changes and
metformin therapy for T2D prevention in individuals with impaired glucose regulation. These associations,
including specific phosphatidylcholines and cholesterol esters, remained after adjustments for traditional
clinical risk factors suggesting they could serve as predictors of T2D. Furthermore, these metabolites were
associated with different rates of T2D progression after lifestyle or metformin treatment and may help guide
T2D prevention decisions. The applicant proposes to further extend these findings by (Aim 1) creating
metabolite multi-marker prediction models to assess the ability of these metabolites to prospectively predict
diabetes development, (Aim 2A) integrate these findings with genetics to uncover metabolic pathways that
underly these associations and if they cause diabetes, (Aim 2B) leverage genetics to also identify completely
novel circulating small molecules associated with T2D, and (Aim 3) conduct a small prospective cohort study to
externally validate these metabolites as predictive biomarkers in a real-world clinical setting. This work will lay
the foundation for an NIH R01 application for a clinical trial to assess the predictive utility of metabolite
biomarkers for diabetes prevention and transition the candidate to research independence.
项目概要/摘要
背景:2 型糖尿病 (T2D) 的发病率和患病率不断上升,可以通过以下方法缓解:
通过行为改变或药物治疗对高危个体进行成功预防。
确定特定个体患糖尿病的风险以及哪种预防性治疗最有效,
然而,这仍然是一个临床困境。代谢生物标志物代表了解决这些问题的一种新方法
临床挑战,还可能揭示疾病发展的机制。这五年的辅导生涯
开发提案详细介绍了生物标志物发现和临床方面的转化研究培训计划
研究实施的目的是确定糖尿病的代谢预测因子和预防性治疗
影响。候选人: 申请人是贝斯以色列最近任命的内分泌学教员
女执事医疗中心的长期目标是成为研究代谢的医师科学家
参与 T2D 发生和进展的途径。她在分子领域拥有2.5年的经验
大型人类研究中的剖析和概述的提案建立在这一背景之上,以提供新的领域
专业知识包括预测模型、遗传学和临床研究设计。培训:申请人的
发展将通过实验室培训、教学课程(包括正在进行的 MPH)、
和科学会议。候选人的导师是分子分析、综合分析领域公认的领导者
“组学”和心脏代谢疾病。她的共同导师是 T2D 遗传学领域的领导者,她的成员
咨询委员会在 T2D、非靶向领域拥有杰出的指导记录和丰富的专业知识
代谢组学、统计模型和临床试验。研究:最近,申请人发现了独特的
一项大型随机对照试验中与 T2D 相关的代谢特征比较了生活方式的改变和
二甲双胍疗法可用于血糖调节受损个体的 T2D 预防。这些协会,
包括特定的磷脂酰胆碱和胆固醇酯,在传统的调整后仍然保留
临床危险因素表明它们可以作为 T2D 的预测因子。此外,这些代谢物
与生活方式或二甲双胍治疗后不同的 T2D 进展率相关,可能有助于指导
T2D 预防决策。申请人建议通过(目标 1)创建来进一步扩展这些发现
代谢物多标记预测模型,用于评估这些代谢物前瞻性预测的能力
糖尿病的发展,(目标 2A)将这些发现与遗传学相结合,以揭示代谢途径
在这些关联的基础上,如果它们导致糖尿病,(目标 2B)利用遗传学来完全识别
与 T2D 相关的新型循环小分子,并且(目标 3)进行一项小型前瞻性队列研究
在现实世界的临床环境中从外部验证这些代谢物作为预测生物标志物。这项工作将奠定
为 NIH R01 临床试验申请奠定基础,以评估代谢物的预测效用
预防糖尿病的生物标志物并将候选人转变为研究独立性。
