Amplifying gene expression with RNA-targeted therapeutics
RNA-targeted NBTs that are currently being used to upregulate gene expression address both transcriptional and translational mechanisms and can be roughly divided into two groups: (1) NBTs that increase mRNA abundance by enhancing transcription or increasing mRNA stability (Fig. 3) and (2) NBTs that optimize translation (Fig. 4). Strategies in the first…
