Infographic showing endogenous adenosine enzymes acting on RNA (ADARs) edit genetic material in the cell by attaching to naturally occurring double-stranded RNAs, including mRNAs, and switching out A bases with I bases (left). Therapeutic RNA editing platforms based on this mechanism fall into one of two categories: either they use engineered enzymes, which generally consist of the editing part of the ADAR enzyme attached to another protein such as Cas13 that boosts specificity, alongside a guide RNA that targets the enzyme to the desired location (middle); or they consist of a guide RNA alone, which recruits an endogenous ADAR to edit the target sequence (right).
