CRISPR gene editing - Wikipedia
It is based on a simplified version of the bacterial CRISPR - Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed or new ones added in vivo.

What is CRISPR/Cas9? - PMC - PubMed Central (PMC)
CRISPR/Cas9 is a gene-editing technology which involves two essential components: a guide RNA to match a desired target gene, and Cas9 (CRISPR-associated protein 9)—an endonuclease which causes a double-stranded DNA break, allowing modifications to the genome (see figure 1).
Mechanism and Applications of CRISPR/Cas-9-Mediated Genome Editing
Clustered regularly interspaced short palindromic repeat (CRISPR) and their associated protein (Cas-9) is the most effective, efficient, and accurate method of genome editing tool in all living cells and utilized in many applied disciplines.

2013年10月24日 · Here we describe a set of tools for Cas9-mediated genome editing via nonhomologous end joining (NHEJ) or homology-directed repair (HDR) in mammalian cells, as well as generation of modified...
What are genome editing and CRISPR-Cas9? - MedlinePlus
CRISPR-Cas9 was adapted from a naturally occurring genome editing system that bacteria use as an immune defense. When infected with viruses, bacteria capture small pieces of the viruses' DNA and insert them into their own DNA in a particular pattern to create segments known as CRISPR arrays.

Exagamglogene autotemcel (exa-cel), sold under the brand name Casgevy, is the first and only CRISPR-based therapy to receive regulatory approval anywhere internationally. 6, 7 Exa-cel is a CRISPR Cas9 gene-editing therapy intended to treat certain people with sickle cell disease or transfusion-dependent beta-thalassemia. 1, 8 (At the time of ...
CRISPR technology: A decade of genome editing is only the …
By leveraging CRISPR-Cas9’s most fundamental activity to create a targeted genetic disruption in a gene or gene regulatory element, scientists have built successful platforms for the rapid creation of knockout mice and other animal models, genetic screening, and multiplexed editing.
Genome-Editing Technologies: Principles and Applications
Therapeutic gene editing in a mouse model of human hereditary tyrosinemia has also been reported using both hydrodynamic injection of plasmid DNA encoding CRISPR-Cas9 (Yin et al. 2014) and by combining nanoparticle-mediated delivery of Cas9-encoding mRNA with AAV-mediated delivery of the DNA template for gene correction (Yin et al. 2016).
