项目摘要
PROJECT SUMMARY/ABSTRACT
tRNA-derived RNA Fragments (tRFs), a newly discovered family of non-coding RNAs (ncRNAs), are emerging
as essential disease biomarkers and regulators. Our recent publication demonstrated that tRFs are the most
impacted small ncRNAs (sncRNAs) by Alzheimer's disease (AD) in the hippocampus. The changes are mainly
from five tRFs, with one proven to correlate with the disease severity of AD experimentally. The correlation
between an AD-impacted tRF and AD severity was also present in serum samples , supporting tRFs as promising
AD indicators and potential prognostic/diagnostic biomarkers. Herein, we propose exploring a combination of an
unbiased discovery method and a newly developed biomedical quantification approach to investigate whether
the expression level of tRFs in the peripheral serum reflects the onset and progress of AD. During the discovery
R61 phase, we will determine the clinical reliability of serum biomarkers to differentiate AD subjects from healthy
individuals or individuals with non-AD dementia or non-dementia neurodegenerative diseases (Aim 1). We will
then determine the lead tRF signatures or signature compositions and investigate the correlation between their
changes with AD severity (Aim 2). The studies of the R61 phase will be mainly cross-sectional. During the R33
phase, we will investigate whether the AD biomarkers and their quantification assay can distinguish AD from its
early mild cognitive impairment (MCI) stage. We will determine biomarker changes in disease progression in
patients between baseline and subsequent follow-up patient visits. The patients who are healthy or have stable
MCI over the years will be used as controls. The culmination of these aims will benefit both prognosis and
diagnosis of AD. The feasibility of this approach is established by sample availability and our extensive research
experience in tRFs and clinical service experience in AD. The overall goal of our research is to discover AD
molecular biomarkers that could improve AD prevention and diagnosis and monitor the therapeutic efficacy in
the future.
项目总结/摘要
tRNA衍生的RNA片段(tRFs)是新近发现的一类非编码RNA(ncRNA)
作为重要的疾病生物标志物和调节剂。我们最近的出版物表明,tRFs是最
影响小ncRNA(sncRNA)的阿尔茨海默病(AD)在海马。变化主要是
从五个tRF,其中一个被证明与AD的疾病严重程度相关。的相关性
AD影响的tRF和AD严重程度之间的关系也存在于血清样本中,支持tRF是有希望的
AD指标和潜在的预后/诊断生物标志物。在此,我们建议探索一种
公正的发现方法和新开发的生物医学量化方法,以调查是否
外周血清中tRFs的表达水平反映了AD的发生和发展。在发现
R61阶段,我们将确定血清生物标志物的临床可靠性,以区分AD受试者和健康受试者。
个体或患有非AD痴呆或非痴呆神经变性疾病的个体(目的1)。我们将
然后确定导联tRF特征或特征成分,并研究它们之间的相关性,
随着AD严重程度的变化(目标2)。R61阶段的研究将主要是横向研究。在R33
我们将研究AD生物标志物及其定量分析是否能区分AD及其
早期轻度认知功能障碍(MCI)。我们将确定疾病进展中的生物标志物变化,
基线和后续随访患者访视之间的患者。健康或病情稳定的患者
将这些年的MCI用作对照。这些目标的实现将有利于预后,
AD的诊断这种方法的可行性是建立在样本的可用性和我们广泛的研究
tRF经验和AD临床服务经验。我们研究的总体目标是发现AD
分子生物标志物,可以改善AD的预防和诊断,并监测治疗效果,
