目前有两种技术平台用于蛋白质功能的去除:(A)转录后水平的RNAi介导的基因沉默,和(B)翻译后水平的蛋白质功能的体内敲除。这两种方法都有很大的治疗应用前景。相关的问题是如何在这些替代方法之间做出选择。这篇评论考察了这些新兴技术平台的优势和劣势。与体内介导的蛋白质功能敲除相比,RNAi方法在技术上的挑战性要小得多,但它的主要限制是非特异性。尽管为特定的细胞内蛋白靶点产生体内抗体是费时费力的,但可以获得更高水平的特异性。归根结底,这些战略之间的选择取决于所讨论的具体应用,以及这两个技术平台的进一步技术进步。
Currently there are two technology platforms for the ablation of protein function: (a) RNAi-mediated gene-silencing at the post-transcriptional level, and (b) intrabody knockout of protein function at the post-translational level. Both approaches hold much promise for therapeutic applications. The pertinent question is how to choose between these alternative approaches. This commentary examines the advantages and disadvantages of these newly-emerging technology platforms. The RNAi approach is much less technically challenging than the intrabody-mediated knockout of protein function, but its major limitation is non-specificity. Although it is time-consuming and labor-intensive to generate intrabodies for specific intracellular protein targets, a much higher level of specificity can be attained. Ultimately, the choice between these strategies depend on the specific application in question, as well as on further technical advances in both technology platforms.
