Gene editing extends lifespan in mouse model of prion disease

Broad Institute

The treatment, which uses base editing to make a single-letter change in DNA, reduced levels of the disease-causing prion protein in the brain by as much as 60 percent. In 2018, Liu, who works on the same floor as Minikel and Vallabh at Broad, approached them and proposed a collaboration.

A Visual Guide to Genome Editors

Codon

Certain CRISPR components can add short DNA sequences from the genomes of defeated viruses into the bacterium’s own genome, creating a type of protective “memory.” If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.

Levers for Biological Progress

Codon

For example, cloning DNA molecules and inserting them into cells — a process required for basically all experiments in molecular biology — takes up to a week of work. Perhaps you’ve seen this chart before, which shows the falling costs of DNA sequencing over the last two decades. If we could get E.

Issue 07 is Coming on Monday

Codon

The event hosts will provide snacks and drinks, and the winning teams will get signed copies of our DNA books and free hats. Eryney Marrogi walks us through today’s most noteworthy gene delivery vehicles — AAVs, Lentivirus, Lipid Nanoparticles, and Herpes Simplex Virus — explaining the advantages and limitations of each.

Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

Broad Institute

Williams January 8, 2024 Credit: Susanna Hamilton, Broad Communications Researchers have developed virus-like particles that can deliver gene-editing cargo to cells, including those in the mouse brain. Prime editing, described in 2019 by Liu’s group, can make longer and more diverse types of DNA changes than other types of editing.
