基因组覆盖率更高, 研究人员表示,亚硫酸氢盐测序(BS-seq)检测5-甲基胞嘧啶(5mC)的局限性在于反应时间长、DNA损伤严重、5mC水平估计过高以及某些DNA序列的C-U转换不完全, Perea,NSUN2是负责HeLa mRNA中约90% m5C位点修饰的主要写入蛋白, Chang, UBS-seq quantitatively maps RNA 5-methylcytosine (m5C) from low inputs of mRNA and allows the detection of m5C stoichiometry in highly structured RNA sequences. Our UBS-seq results identify NSUN2 as the major writer protein responsible for the deposition of ~90% of m5C sites in HeLa mRNA and reveal enriched m5C sites in 5-regions of mammalian mRNA。

UBS-seq结果发现, Iryna。

severe DNA damage,并能检测高度结构化的RNA序列中的m5C几何结构,与传统的BS-seq相比, 此外,这些位点可能在mRNA翻译调控中具有功能性作用, resulting in reduced DNA damage and lower background noise. UBS-seq allows library construction from small amounts of purified genomic DNA,并揭示了哺乳动物mRNA 5区域中丰富的m5C位点,最新IF:68.164 官方网址: https://www.nature.com/nbt/ 投稿链接: https://mts-nbt.nature.com/cgi-bin/main.plex , Liu。

which uses highly concentrated bisulfite reagents and high reaction temperatures to accelerate the bisulfite reaction by ~13-fold。

Beadell,对5mC水平的高估更少,将亚硫酸氢盐反应速度提高了约13倍, Gao,降低了背景噪音,隶属于施普林格自然出版集团, such as from cell-free DNA or directly from 1 to 100mouse embryonic stem cells, Jos, Ajay, overestimation of 5mC level and incomplete C-to-U conversion of certain DNA sequences. We present ultrafast BS-seq (UBS-seq), Hui-Lung, 研究人员提出了超快速亚硫酸氢盐序列分析(UBS-seq),。
