In addition to CRISPR research, the IGI works to advance public understanding of CRISPR and genome engineering and guide the ethical use of these technologies. 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 ...
On 26 November 2018, The CRISPR Journal published ahead of print an article by He, Ryan Ferrell, Chen Yuanlin, Qin Jinzhou, and Chen Yangran in which the authors justified the ethical use of CRISPR gene editing in humans. [74] As the news of CRISPR babies broke out, the editors reexamined the paper and retracted it on 28 December, announcing:
For example, corporations may be able to take unfair advantage of patent law or other ways of restricting access to genome editing and thereby may increase the inequalities. There are already disputes in the courts where CRISPR-Cas9 patents and access issues are being negotiated. [78]
Many experts disagreed with the paper and criticized it through journal articles [68] and social media, suggesting that unusual CRISPR treatments were used in the initial paper and the sample size was too low for significance (n=2). Nature Methods has issued two editorial notes on the paper, [69] and later retracted it. [70]
For example, CRISPR allows researchers to quickly generate animal and human cell models, allowing them to study how genes function in a nervous system. By introducing mutations that pertain to various diseases within these cells, researchers can study the effects of the changes on nervous system development, function, and behavior. [ 201 ]
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.
A gene drive is a natural process [1] and technology of genetic engineering that propagates a particular suite of genes throughout a population [2] by altering the probability that a specific allele will be transmitted to offspring (instead of the Mendelian 50% probability). Gene drives can arise through a variety of mechanisms.
