项目摘要
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.
项目摘要
我们在此提案中的目标是确定涉及同步的生物网络,并
到期。为了实现这一目标,我们在预防中心之间建立了合作的努力
辛辛那提儿童医院医疗中心(CCHMC)和系统研究所的早产
西雅图的生物学(ISB)对“ OMICS”数据进行系统级别分析。扰动的生长和成熟度可以
导致位置功能不全,这是不良妊娠结局的很大比例的基础
作为早产。缺乏知识的常规占地发展和极大的阻碍
任何对占地不足的研究。胎盘生长和发展发生在整个妊娠和
学期到期。因此,至关重要的是确定所涉及的网络并根据
妊娠长度。我们的核心假设是,关键的生物网络对胎盘生长和
可以通过转录组,蛋白质组学和代谢组的交点来识别成熟度
学期和早产的数据。此外,使用纵向保护热带和代谢组学
数据,我们可以确定这些途径如何改变妊娠和正常和早产之间的不同
斑块。我们将通过以下目的检验这一假设:
目标1:通过
分析纵向“ OMICS”数据。使用公开可用的转录组数据,我们将生成一个
在妊娠期间,表达基因的分子谱。我们还将确定
胎盘秘密并识别出现反映胎盘的物质尿液中的生物标志物特征

AIM 2:鉴定与位置成熟度相关的分子途径。我们将利用网络
拓扑算法以鉴定早产和术语plicetae中分子途径的变化。这些数据将
与公开可用的数据结合使用,以识别这些途径中的分子途径和基因
在学期和早产之间有所不同,以洞悉安慰成熟度。
目标3:生成胎盘特异性转录网络,用于识别调节机制
参与占地成熟度。我们将构建基因组规模的斑点特定模型
使用我们新开发的转录调节网络分析的转录调节网络
(TRENA)方法,该方法利用NIH的编码项目中的大量信息。我们将
表征哪些转录调节剂最有可能导致扰动基因表达,
信号通路和下游目标。以前未知或理解的网络或基因已识别
针对进一步分析位置生长和成熟度以及未来的前瞻性临床研究。
