Cas9

In a bid to address safety concerns about immune reactions during treatment with CRISPR-based therapeutics, a new technique speeds up how quickly the body destroys the DNA-cutting enzyme Cas9.

Researchers turned to base editors to correct mutations causing the rare genetic disease Fanconi anemia without inducing double-strand DNA breaks.

A new technique goes beyond CRISPR and writes two complementary strands of DNA directly into the genome.

The approach, called GRAND, uses a second guide RNA to write complementary strands of DNA in targeted genomic locations, resulting in efficient insertions that can be hundreds of base pairs long.

A new method has allowed researchers to conduct the first gene knock-out and knock-in edits on cockroaches and may extend to many other insects.

The results reveal evolutionary relatives of the Cas9 enzyme now used extensively in biotechnology.

The guidance comes after two years of consulting with hundreds of stakeholders, including indigenous peoples, religious leaders, patient groups, and scientists.

A CRISPR-based, paper-strip test developed by Indian researchers performs as well as real-time PCR in identifying the presence of SARS-CoV-2 and returns results within an hour.

Emmanuelle Charpentier and Jennifer Doudna reprogrammed the bacterial immune response into one of the most popular tools for genetics and molecular biology.

Researchers slowed disease progression in the mice by injecting two different viral vectors, each containing one part of the DNA encoding the Cas9 protein, to edit the causative gene.

In demonstrations in cell lines, the technique has a similar efficacy to CRISPR-Cas9, but fewer off-target effects.

Researchers use a CRISPR-Cas9 strategy to expand a desired trait from 50 percent of mouse pups to about 72 percent.

A mouse study details a method called VIVO that predicts the accuracy of any guide RNA.

Researchers have developed a variety of techniques to detect when CRISPR misses the mark.

A tweaked Cas9 nuclease reduces off-target effects to levels below that of previous versions of the enzyme.

In human cells, researchers deploy the genome editor to snip out toxic repetitive sequences.

Scientists correct a mutation in fertilized eggs that causes a severe cardiac disease.

Multiple DNA breaks at either the centromere or the long arm of the mouse Y chromosome cause it to fragment and disappear.
