CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]
Targeted gene knockout using CRISPR/Cas9 requires the use of a delivery system to introduce the sgRNA and Cas9 into the cell. Although a number of different delivery systems are potentially available for CRISPR, [37] [38] genome-wide loss-of-function screens are predominantly carried out using third generation lentiviral vectors.
Free public resources include: CRISPRpedia — a free textbook-style resource for learning about the biology, applications, and ethics of CRISPR and genome editing, with chapters edited by Doudna, Urnov, Ronald, and other IGI investigators. [68] [69] CRISPR Made Simple — an educational guide to CRISPR for younger students and teachers. [70]
CRISPR-Cas design tools are computer software platforms and bioinformatics tools used to facilitate the design of guide RNAs (gRNAs) for use with the CRISPR/Cas gene editing system. CRISPR-Cas [ edit ]
In March 2017 Intellia and Regeneron, partners in co-developing a CRISPR-based treatment for transthyretin amyloidosis, presented data from a gene editing experiment in mice. [16] [17] By that time, University of California had lost a challenge to Broad's CRISPR patents, putting Intellia at a disadvantage relative to Editas. [16]
CRISPR-associated transposons have been harnessed for in vitro and in vivo gene editing at different targets, in different hosts, and with different payloads. All CAST components of the Tn6677 system from Vibrio cholerae have been combined into a single plasmid and confirmed to deliver up to 10kb transposons at near 100% efficiency. [16]
