在mRNA递送领域,多种含胺基的聚酯已被开发用于mRNA递送,包括聚(β-氨基酯)[poly(β-aminoester),PBAEs,4]、氨基聚酯(amino polyester,APEs)和电荷改变释放转运体(charge-altering releasable transporters,CARTs,5和6)等。其中,PBAEs 是经典...
在转录起始位点(the start site of transcription)上游,有一段保守启动子序列(consensus promoter sequence)。RNA polymerase 识别并且结合到特异性的启动子上(recognizes and binds specific promoter),打开(melt)转录起始位点附近的DNA双链,启动RNA的从头合成(initiate de novo synthesis of RNA)。RNA polymerase 利用NT...
一个是NCBI Reference Sequences (RefSeq)区域；一个是每个转录本的Nucleotide界面。

Analysis of these sequences reveals that majority of the protein products contain domains that are DNA/RNA-binding, kinases, growth factors, or involved in immune response or cell proliferation. Thus, the proteins translated from non-canonical codons seem to be implicated in regulatory role and/or...

第一种在mRNA疫苗的设计中最为常用,通常直接选取受用群体内高表达基因的5’UTR,例如人alpha珠蛋白的 5’UTR、鼠源alpha珠蛋白的 5’UTR或猫源DNAH2基因的5’UTR等。 第二种是通过指数富集(SELEX)的方式来实现 5’UTR的系统演化,这种方法耗时且筛选...
protein synthesisDNA in the cell nucleus carries a genetic code, which consists of sequences of adenine (A), thymine (T), guanine (G), and cytosine (C) (Figure 1). RNA, which contains uracil (U) instead of thymine, carries the code to protein-making sites in the cell. To make RNA...
