Breakthrough In Gene Editing Holds Promise For New Therapies

Posted by in categories: bioengineering, biotech/medical, genetics

Researchers have significantly improved gene-editing techniques. This new method, called eePASSIGE, can insert or replace entire genes in human cells with much higher efficiency than previous methods. This advancement could lead to a single gene therapy for diseases caused by various mutations in a single gene, like cystic fibrosis. Traditionally, gene therapy required a different treatment for each mutation.

EePASSIGE combines prime editing, which edits small stretches of DNA, with new enzymes that insert large pieces of DNA. This allows scientists to introduce a healthy copy of a gene directly where it belongs in the genome.

“This is one of the first examples of targeted gene integration with potential for therapeutic applications,” said Dr. David Liu, senior author of the study. “If these efficiencies translate to patients, many genetic diseases could be treated.”
