我想更正一些我错了的RNAi理解:
RNAi is the drug.
RNAi delivery approaches include conjugates, liposomal nanoparticles (LNPs), and viral vectors. Nanoparticles deliver synthetic dsRNA, whereas viral vectors deliver a transcriptional template to the nucleus. Cellular uptake occurs nonspecifically or via receptor-mediated endocytosis. Nanoparticles deliver the RNAi trigger to the cytoplasm. The trigger enters the RNAi pathway at the RISC or Dicer processing stage. Transcriptional templates produce hairpin RNAs that enter the pathway at an earlier, nuclear stage. Ultimately, an active RISC complex is formed that cleaves the mRNA target.
RISC, RNA-induced silencing complex; shRNA, short hairpin-mediated RNA.
RNAi的递送方法包括偶联物,脂质体纳米颗粒(岭澳核电站),和病毒载体。纳米粒子递送合成的双链RNA,而病毒载体递送的转录模板到细胞核。发生非特异性或通过受体介导的内吞作用的细胞摄取。纳米粒子递送所述RNAi触发到细胞质。触发进入RNAi途径在RISC或切酶处理阶段。转录模板产生进入途径在较早,核级发夹RNA。最终,活性RISC复合物所形成的切割的mRNA靶。 RISC,RNA诱导沉默复合体; shRNA的短发夹RNA介导的。 |
