But prime editing, a CRISPR technique developed in David Lius lab in 2019, has added considerably more precision and flexibility to the CRISPR editing world. All of this is possible without double-strand breaks (DSBs) or donor DNA templates. Plus, it can combine different types of edits with one another.
“Meet Invisible Woods: a clean, refreshing scent revived from extinct flower DNA ,” beneath an image of “origin flower” Wendlandia angustifolia. • compare the DNA sequence to similar genes in other species. • tweak a lab-made copy of the DNA sequence using clues from other plant species.
Their new editors are more efficient and specialized than previous versions, and are able to modify DNA in cultured cells and in animals that have been difficult to edit, including in immune system cells and inside the brain. In the new work, they focused on improving the heart of the prime editing system—the reverse transcriptase. “We
Prime editing is a versatile genome editing technology that allows precise modifications of DNA (replacements, small insertions, and deletions) without introducing DNA double-strand breaks (Anzalone et al., 2019; Chen & Liu, 2023).
In the new work published today in Nature Biotechnology , the team adapted engineered virus-like particles (eVLPs) that they had previously designed to carry base editors — another type of precision gene editor that makes single-letter changes in DNA.

Last week DNA Science covered a setback in a clinical trial of a gene therapy for Duchenne muscular dystrophy (DMD). It aims to correct the faulty instructions at the DNA level, straightforward, at least conceptually, because mutations are deletions, of part or all of the gene. That’s not the case for ALS.

(NASDAQ:CDXC) today highlighted a new study published in The European Molecular Biology Organization Journal looking at the effect of nicotinamide riboside (NR) on maintaining telomeres, the protective regions at the end of DNA strands. Telomeres are “caps” at the end of chromosomes that protect DNA from getting worn away as cells replicate.
Cancer is a disease of the genome, driven by genetic mutations within a tumour’s DNA.

The chefs at Farma know that by embracing food technologies such as recombinant DNA, precision fermentation, and cell culture, food can become more nutritious and better for the planet. Since its doors opened to the public a few weeks ago, Farma has crusaded against the apocryphal purity of organic foods.
So therapeutics that focus on RNA are designed to stop the DNA from coding for disease-causing proteins. On September 30, 2019, Ribometrix signed a strategic collaboration deal with Boston’s Vertex Pharmaceuticals. Targeting RNA is believed to be a way to develop therapeutics for so-called undruggable proteins.
