常见问题列表
N1-甲基-假尿苷主要用作生物核苷酸修饰剂，以提升mRNA蛋白表达效率。N1-甲基-假尿苷可以降低外源合成mRNA的翻译效率：mRNA药物的最终目的是在细胞内表达出治疗性蛋白。研发人员开始探索化学修饰核苷酸是否有助于提升mRNA蛋白翻译效率。在最初报道N1-甲基-假尿嘧修饰RNA可以提升蛋白表达水平的研究中发现这种助益部分原因是由于N1-甲基-假尿苷修饰RNA减弱TLR3的激活反应造成的。
N1-甲基假尿苷在生物医药研究中具有潜在的应用前景。它的独特特性使其成为治疗疾病、研发新型RNA药物和生物标记物的研究热点。研究人员正在深入探索N1-甲基假尿苷在基因表达调控、病毒感染和免疫调节等领域的作用机制，以期发现更多的生物学功能和潜在的临床应用。
N1-methyl-pseudouridine (1-Methylpseudouridine) 是一种甲基假尿苷，翻译性能优于 5 mC 和 5 mC/N1-methyl-pseudouridine。通过增加核糖体密度，mRNA 中的 N1-methyl-pseudouridine 以 eIF2α 依赖性和独立机制增强翻译。
1、RNA修饰：N1-甲基假尿苷是一种常见的RNA修饰物，它通过甲基化反应嵌入到RNA链中。这种修饰可以在RNA折叠和功能中发挥关键作用，并影响RNA的稳定性、转录后修饰和翻译调控等过程。
2、抗病毒活性：N1-甲基假尿苷在抗病毒免疫响应中发挥重要作用。研究表明，它的存在可以增强RNA的稳定性，抑制病毒RNA的复制和病毒感染的扩散。
3、翻译调控：N1-甲基假尿苷修饰可通过调节RNA的翻译过程来影响蛋白质合成。它可以影响核糖体的识别和结合，从而调控特定基因的翻译速率和翻译起始位点选择。
4、基因表达调节：N1-甲基假尿苷还参与基因表达的调节过程。它可以影响RNA的稳定性和剪接模式，从而调节基因转录后的表达水平和转录变体的生成。
Incorporation of N1-methyl-pseudouridine into mRNA modifies mRNAs produced higher amounts of luc than the standard Luc mRNA in HEK293T cells. Incorporation of N1-methyl-pseudouridine nucleoside modification in both Luc and GFP mRNA enhances the initiation step of translation, in part by suppressing eIF2α phosphorylation. In addition, polysome formation and growth on the NN1-methyl-pseudouridine-containing Luc mRNA is enhanced due to the reduction of elongation rate. In all the in vitro translation systems, incorporation of N1-methyl-pseudouridine in Luc and GFP mRNAs dramatically enhanced translation. The N1-methyl-pseudouridine-Luc mRNA is associated with heavier polysomes than Luc mRNA.
N1-methylpseudouridine-incorporated mRNA outperforms pseudouridine-incorporated mRNA by providing enhanced protein expression and reduced immunogenicity in mammalian cell lines and mice.
