The targeted deletion, replacement, integration, or inversion of genomic sequences could be used to study or treat human genetic diseases, but existing methods typically require double-strand DNA breaks (DSBs) that lead to undesired consequences including uncontrolled indel mixtures and chromosomal abnormalities. Here, we describe twin prime editing (twinPE), a DSB-independent method that uses a prime editor (PE) protein and two prime editing guide RNAs (pegRNAs) for the programmable… 

Designing and executing prime editing experiments in mammalian cells.

Current best practices for conducting PE and twinPE experiments are described and the design and optimization of pegRNAs are described, which offer guidelines for how to select the proper PE system for a given application and detailed instructions on how to perform PE in mammalian cells.

Bi-PE: bi-directional priming improves CRISPR/Cas9 prime editing in mammalian cells

It is demonstrated that positioning the nick sgRNA nearby the templating sequences of the pegRNA facilitated targeted large fragment deletion and that engineering both guide RNAs to be pegRNAs to achieve bi-direction prime editing (Bi-PE) further increase the efficiency and the accuracy of editing products.

Highly efficient CRISPR-mediated large DNA docking and multiplexed prime editing using a single baculovirus

Single baculovirus vectored delivery of single and multiplexed prime-editing toolkits provide a versatile delivery platform for single base to multi-gene level genome interventions, addressing the currently unmet need for a powerful delivery system accommodating current and future CRISPR technologies without the burden of limited cargo capacity.

Cytoplasmic Injection of Zygotes to Genome Edit Naturally Occurring Sequence Variants Into Bovine Embryos

This study investigated the potential to introduce sequence variants, known from the pre-melanosomal protein 17 (PMEL) and prolactin receptor (PRLR) genes, and produce non-mosaic, edited embryos, completely converted into the precision genotype and developed a biopsy-based screening strategy for non- mosaic embryos which has the potential for exclusively producing non-Mosaic animals with intended precision edits.

Recent Advances in Double-Strand Break-Free Kilobase-Scale Genome Editing Technologies.

Recent advances toward DSB-free technologies that enable kilobase-scale modifications including insertions, deletions, inversions, replacements, and others are reviewed.

Highly efficient prime editing by introducing same-sense mutations in pegRNA or stabilizing its structure

SpegRNA is developed by introducing same-sense mutations at proper positions in the reverse-transcription template of pegRNA to increase PE’s base-editing efficiency up-to 4,976-fold (on-average 353-fold).

Modified Gene Editing Systems: Diverse Bioengineering Tools and Crop Improvement

The modifications made to gene-editing systems in recent years are discussed and the capabilities, deficiencies, and applications of these modified gene-EDiting systems are summarized.



Search-and-replace genome editing without double-strand breaks or donor DNA

A new DNA-editing technique called prime editing offers improved versatility and efficiency with reduced byproducts compared with existing techniques, and shows potential for correcting disease-associated mutations.

Programmable editing of a target base in genomic DNA without double-stranded DNA cleavage

E engineered fusions of CRISPR/Cas9 and a cytidine deaminase enzyme that retain the ability to be programmed with a guide RNA, do not induce dsDNA breaks, and mediate the direct conversion of cytidine to uridine, thereby effecting a C→T (or G→A) substitution.

In trans paired nicking triggers seamless genome editing without double-stranded DNA cutting

It is reported that the coordinated formation of paired single-stranded DNA breaks, or nicks, at donor plasmids and chromosomal target sites by RNA-guided nucleases based on CRISPR-Cas9 components, triggers seamless homology-directed gene targeting of large genetic payloads in human cells, including pluripotent stem cells.

Precise genomic deletions using paired prime editing

A prime editing-based method, which induces a deletion using a pair of prime editing gRNAs (pegRNAs) that target opposite DNA strands, effectively programming not only the sites that are nicked but also the outcome of the repair.

Efficient inversions and duplications of mammalian regulatory DNA elements and gene clusters by CRISPR/Cas9

It is reported that targeted DNA fragment inversions and duplications could easily be achieved in human and mouse genomes by CRISPR with two sgRNAs and it is shown for the first time that DNA fragments could be transmitted through germlines in mice and a new role was found in the regulation of members of the Pcdhγ cluster.

Modulating DNA Repair Pathways to Improve Precision Genome Engineering.

Advances toward modulating the activities of the two critical DNA repair pathways, HDR and NHEJ, to enhance precision genome engineering are reviewed.

A programmable Cas9-serine recombinase fusion protein that operates on DNA sequences in mammalian cells

It is demonstrated that recCas9 expressed in human cells can catalyze in situ deletion between two genomic sites, and represents a step toward programmable, scarless genome editing in unmodified cells that is independent of endogenous cellular machinery or cell state.

Unbiased investigation of specificities of prime editing systems in human cells

It was shown that PE specificity in human cells could be further improved by incorporating mutations from engineered Cas9 variants, particularly eSpCas9 and Sniper Cas9, into PE, suggesting that PEs provide a highly specific method of precise genome editing.

Engineered pegRNAs improve prime editing efficiency

The resulting engineered pegRNAs (epegRNAs) improve prime editing efficiency 3 to 4-fold in HeLa, U2OS, and K562 cells and in primary human fibroblasts without increasing off-target editing activity.

Genome-wide specificity of prime editors in plants.

Whole-genome sequencing of 29 PE-treated rice plants confirmed that PEs do not induce genome-wide pegRNA-independent off-target single-nucleotide variants or small insertions/deletions and ectopic expression of the Moloney murine leukemia virus reverse transcriptase as part of the PE is confirmed.
