Unlike DNA, RNA is not self-replicating. Instead,RNA is synthesized from DNA through the process of transcription.During transcription, a segment of DNA is copied to create an RNA molecule. RNA polymerase is the main enzyme, and it uses the DNA strands to make a complementary RNA strand. RN...
A methyltransferase ribozyme, along with the small-molecule cofactorO6-methylguanine, is shown to catalyse the site-specific installation of 1-methyladenosine in various RNAs, providing insights into the catalytic abilities of RNA. Carolin P. M. Scheitl ...
解决此类问题的一种方法是使用spike-in对照RNA-即在文库制备过程中引入预定浓度的外源RNA序列。RNA-seq常用的spike-in有 External RNA Controls Consortium mix (ERCCs),spike-in RNA variants (SIRVs)和sequencing spike-ins (Sequins)。由于spike-in的RNA浓度是预先知道的,并且浓度与产生的reads的数量直接相关,因此...
当使用RNA-seq鉴定DGE时,影响数据的可用性的重要因素是确定每个reads来自转录组中哪个基因的能力。一旦可以明确地确定reads位置,测序更长的reads在基于定量的分析中就没必要了。对于更定加性的RNA-seq分析(例如鉴定特定isoforms),更长的reads可能会更有帮助。 单端测序与双端测序的问题类似。在单端测序中,每个cDNA片...

然后将得到的cDNA进行PCR扩增,并构建PacBio单分子实时(single-molecule, real-time,SMRT)文库。因为短转录本可以很快地扩散到测序芯片的活性表面造成一定的测序偏好,建议选择1至4 kb长度的转录本一起测序,以保证这一长度范围的长短转录本有同等几率进行测序。同时PacBio测序对模板量需求很大,要求进行大体积PCR,需要...
As long-read sequencing technologies continue to advance, the possibility of obtaining maps of DNA and RNA modifications at single-molecule resolution has become a reality. Here we highlight the opportunities and challenges posed by the use of long-read sequencing technologies to study epigenetic and...
2024年1月26日,来自蔚蓝海岸大学联盟的尼斯大学、法国国家科学研究中心等机构的研究人员在Nature Reviews Chemistry上发表了题为Small molecule approaches to targeting RNA的综述。 鉴定RNA结合体的创新方法的开发引起了化学生物学和药物发现领域的极大关注。小分子是探索RNA生物功能和验证RNA作为治疗靶点的重要工具,尽管最...
Arrowhead 在研的 AROHSD 是一种靶向 HSD17β13 的 RNAi 疗法,搭载其独家的靶向 RNAi 分子(targeted RNAi molecule, TRiM)技术,旨在选择性靶向肝细胞中HSD17β13mRNA(见图 2)。TRiM 平台具有多种给药途径以及提高安全性的潜力等多...
and you should be very sure of your sequence. The oligonucleotides can be labeled using a kinase to transfer a radioactive phosphate remnant to the 5' end of the oligo, although this allows insertion of a maximum of one label per molecule, the evidence for which is insensitive. Consequently...
