大脑衰老的生物学机理十分复杂，受到遗传、年龄和环境等多个因素的调控和影响，其中随年龄和环境等因素而变化的表观遗传调控被认为是重要的调控环节之一。基因组中大约90% DNA 都具有转录活性，但其中仅有1.5%的基因能够编码蛋白质，而环状非编码RNAs (circRNAs)即属于不具有编码功能的非编码RNAs范畴。近年来，越来越多的研究证据揭示circRNAs 介导的表观遗传调控在机体的诸多生命过程和...
大脑发育和老化过程十分复杂，涉及遗传、年龄和环境等多个因素的调控和影响，其中由年龄和环境等主要因素导致的表观遗传调控的变化被认为是重要环节之一。基因组中大约90% DNA都具有转录活性，这当中仅有1.5%的基因具有编码蛋白质的功能，而大部分是不具有编码蛋白质功能的，其中就包括长链非编码RNAs (lncRNAs)。近年来，越来越多的研究证据揭示lncRNAs介导的表观遗传调控在机体的许多生命过程和...

RNA-dependent RNA polymerase of turnip crinkle virus and the effect of coat protein on the replication of subviral RNAs
Biological sciences
2015/1/28
In this dissertation, I report the functions of the TCV coat protein in TCV viral and subviral RNA replication using in vivo and in vitro systems. In chapter 2, I present my results on construction of...
Box C/D small nucleolar RNAs: Biogenesis, structure and utilization for in vivo ribozyme studies
Eukaryotic cells biological origin yeast capsule
2014/12/11
Eukaryotic cells contain scores of small nucleolar RNAs (snoRNAs), which are required for maturation of pre-rRNA. Two large snoRNA families exist defined by vital box C/D and box H/ACA motifs. The goa...
The major function of eukaryotic small nucleolar RNAs is nucleotide modification in ribosomal RNA
Small nucleoli element RNA
2014/12/11
Small nucleolar RNAs (snoRNAs) can be divided into two large families based on conserved sequence elements. These two classes are the box C/D snoRNAs and the box H/ACA snoRNAs. At the onset of this th...
Symptom modulation by subviral RNAs associated with turnip crinkle virus
Plants the virus the virus symptoms radish knit virus satellite RNA and toxicity
2014/12/11
Many plant RNA viruses provide replication and encapsidation functions for one or more subviral RNAs that can modulate the symptoms of the associated helper virus. In this dissertation, I report my st...

Biologically synthesized poly(α,L-glutamic acid) (PLGA) can be chemically modified to form monodisperse poly(γ-benzyl α,L-glutamate) (PBLG). This material shows rare smectic ordering where macromolecu...
细胞机器是如何对基因调控的小RNAs分子前体进行分选的
细胞机器 基因调控 小RNAs分子前体
2010/8/18
这个研究由冷泉港实验室的Benjamin Czech负责，他提出了一个问题：当双链RNAs进入RNAi通路时，展开的过程中是否可以观察到截然不同的模式。RNAi简称为RNA干扰，是双链RNA的一个生物学反应，能够在调节基因表达时达到顶峰。这种现象已经在生物体中普遍存在，从植物到蠕虫、到果蝇还有人类。
