Assessing and advancing the safety of CRISPR-Cas tools: from DNA to RNA editing

Abstract: CRISPR-Cas gene editing has revolutionized experimental molecular biology over the past decade and holds great promise for the treatment of human genetic diseases. Here we review the development of CRISPR-Cas9/Cas12/Cas13 nucleases, DNA base editors, prime editors, and RNA base editors, focusing on the assessment and improvement of their editing precision and safety, pushing the limit of editing specificity and efficiency. We summarize the capabilities and limitations of each CRISPR tool from DNA editing to RN… Show more

“…Unlike DNA editing, RNA editing offers an alternative to genome editing in certain applications in an invertible and controllable manner [ 21 ] ( Figure 2 ). First of all, recognition of RNA molecules circumvents hindrance by DNA modifications; for example, chromatin accessibility [ 22 ].…”

“…This tool has made up for the shortcomings of CRISPR/ Cas9 technology in double-strand breaks, including the deletion, translocation and rupture of large fragments of genomic DNA. 15,34,35 The technique is extensively used to construct and treat disease models, especially single-gene genetic diseases. For example, Liu et al 36 packaged the most promising combination of AID-CBEmax and TMC1 guide RNA into dual-AAV using a split-intein delivery system.…”
