ENCODE和全基因组关联项目表明,大部分基因组被转录成RNA,很少被翻译成蛋白质。这些和其他功能研究表明,可药物转录组比可药物蛋白质组大得多。这篇综述强调了定义可药物RNA靶点和基因组RNA结构-活性关系的方法。结合化合物可以通过基于序列的设计和各种作用模式(例如,抑制翻译或指导pre-mRNA剪接结果)来识别和优化为结构特异性配体。此外,通过化学诱导的接近来指导蛋白质活性对抗感兴趣的RNA的策略是一个新兴的领域,已经在细胞和临床前动物模型中得到了验证,我们描述了它可能允许快速进入影响RNA生物学的新途径。这些方法和独特的作用模式表明,更多的rna可能比蛋白质更适合靶向。
The ENCODE and genome-wide association projects have shown that much of the genome is transcribed into RNA and much less is translated into protein. These and other functional studies suggest that the druggable transcriptome is much larger than the druggable proteome. This review highlights approaches to define druggable RNA targets and structure–activity relationships across genomic RNA. Binding compounds can be identified and optimized into structure-specific ligands by using sequence-based design with various modes of action, for example, inhibiting translation or directing pre-mRNA splicing outcomes. In addition, strategies to direct protein activity against an RNA of interest via chemically induced proximity is a burgeoning area that has been validated both in cells and in preclinical animal models, and we describe that it may allow rapid access to new avenues to affect RNA biology. These approaches and the unique modes of action suggest that more RNAs are potentially amenable to targeting than proteins.
