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
Perhaps more telling, I recently discovered a previously unknown branch of my own family tree that includes a dozen half-siblings that I know of, from a DNA test that I didn’t even remember taking. It was eerily like forensic scientists using familial DNA to track down serial killers. Which one was our biodad?
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).
Bowel cancer is the fourth most common cancer in the UK, accounting for 11 percent of all new cancer cases from 2017 to 2019 1 , and is the second most common cause of cancer death in the UK, accounting for 10 percent of all cancer deaths in the same time period.
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.

This includes recipients of a three-million-dollar grant , awarded by the National Science Foundation in 2019, to “design, construct, and safely deploy synthetic mirror cells.” DNA and RNA molecules are also built from exclusively right-handed nucleic acids. 4 As far as we know, right-handed proteins never occur naturally.
When COVID-19 emerged in 2019, by contrast, mRNA vaccines developed by Pfizer and Moderna took just 326 days from the initial sequencing of the virus to gaining approval for emergency use. DNA-encoded antiviral proteins delivered to the nose or lungs of mice have previously been shown to protect against influenza or COVID-19.
One cell at a time Slide-seq, reported in 2019 , involves transferring slices of tissue onto arrays of special beads, each one tagged with a DNA barcode that identifies its location in the array.
At the Broad, Martin is also helping lead data analysis in two large international studies that are sequencing the DNA of people from Africa and Latin America to learn about the genetics of severe mental illness. That paper changed hearts and minds,” Neale, a co-author, said of the 2019 paper in Nature Genetics.
Gene-editing methods allow researchers to modify DNA, resulting in alterations in physical characteristics such as eye colour and susceptibility to diseases. To achieve this, scientists utilise various technologies that function similarly to scissors, precisely cutting the DNA at a particular location.
Prime editing, a pioneering genome editing technique, was applied, enabling the scientists to introduce a single DNA base substitution at a time and to assess individual variant function at the TSPAN14 AD risk locus. 2019 August 30 [cited 2023 October 6]; 11(233):20.
