中文摘要
项目摘要
我们的目标是确定参与同步胎盘生长的生物网络,
成熟为了实现这一目标,我们建立了一个合作的努力,
辛辛那提儿童医院医疗中心(CCHMC)和系统研究所
生物学(ISB)在西雅图进行“组学”数据的系统级分析。受干扰的生长和成熟可以
导致胎盘功能不全,这是很大一部分不良妊娠结局的基础,
早产。 缺乏有关正常胎盘发育和成熟的知识,
任何关于胎盘功能不全的研究。 胎盘的生长和发育发生在整个妊娠期,
在期限内达到成熟。因此,必须确定所涉网络,
妊娠期的长短我们的中心假设是,对胎盘生长至关重要的关键生物网络,
成熟可以通过转录组学、蛋白质组学和代谢组学的交叉来鉴定
来自足月和早产胎盘的数据。 利用纵向蛋白质组学和代谢组学
数据,我们可以确定这些途径如何在妊娠期间变化,以及正常和早产之间的差异
胎盘我们将通过以下目标来检验这一假设:
目的1:通过筛选胎盘发育中的关键基因和代谢产物,
分析纵向“组学”数据。 使用可获得的转录组数据,我们将生成一个
整个妊娠期胎盘发育中表达基因的分子谱。 我们还将确定
胎盘分泌组和鉴定出现在母体尿中反映胎盘分泌的生物标记物特征

目的2:鉴定与胎盘成熟相关的分子通路。 我们将利用网络
拓扑算法,以确定早产和足月胎盘中分子途径的变化。这些数据将
与实验室可用数据相结合,以确定分子途径和这些途径中的基因
以提供对胎盘成熟度的了解。
目的3:建立胎盘特异性转录网络,以确定调控机制

转录调控网络使用我们新开发的转录调控网络分析

英文摘要
PROJECT SUMMARY
Our goal in this proposal is to identify biological networks involved in synchronizing placental growth and
maturity. To accomplish this goal, we have established a collaborative effort between the Center for Prevention
of Preterm Birth at Cincinnati Children’s Hospital Medical Center (CCHMC) and the Institute for Systems
Biology (ISB) in Seattle to conduct a systems level analysis of “omics” data. Perturbed growth and maturity can
lead to placental insufficiency, which underlies a significant proportion of adverse pregnancy outcomes, such
as preterm birth. A paucity of knowledge regarding normal placental development and maturity greatly hinders
any study of placental insufficiency. Placental growth and development occurs throughout gestation and
reaches maturity at term. Therefore, it is critical to identify the networks involved and to assess them over the
length of gestation. Our central hypothesis is that key biological networks vital to placental growth and
maturity can be identified through the intersection of transcriptomic, proteomic, and metabolomics
data from term and preterm placentae. Furthermore, utilizing longitudinal proteomics and metabolomics
data, we can determine how those pathways change over gestation and differ between normal and preterm
placentae. We will test this hypothesis through the following aims:
Aim 1: Identification of key gene and metabolite signatures involved in placental development by
analyzing longitudinal “omics” data. Using publically available transcriptomic data, we will generate a
molecular profile of expressed genes in placental development throughout gestation. We will also determine
the placental secretome and identify biomarker signatures that appear in maternal urine that reflect placental
maturation.
Aim 2: Identification of molecular pathways associated with placental maturity. We will utilize network
topology algorithms to identify changes in molecular pathways in preterm and term placentae. These data will
be combined with publically available data to identify molecular pathways and genes within those pathways
that differ between term and preterm placentae to provide insight into placental maturity.
Aim 3: Generation of a placenta-specific transcriptional network for identifying regulatory mechanisms
involved in placental maturity. We will construct genome-scale, tissue specific models of placental
transcriptional regulatory networks using our newly-developed Transcriptional Regulatory Network Analysis
(TRENA) approach, which leverages a wealth of information from the NIH’s ENCODE project. We will
characterize which transcriptional regulators are most likely responsible for perturbed gene expression, their
signaling pathways and downstream targets. Previously unknown or understudied networks or genes identified
targeted for further analyses in placental growth and maturity and future prospective clinical studies.
