DNA repair discovery might improve biotechnology: Research

Washington [US], March 5 (ANI): A team of researchers from Michigan State University’s College of Veterinary Medicine made a discovery that may have significance for therapeutic gene editing strategies, cancer diagnostics and therapies and other advancements in biotechnology. Kathy Meek, a professor in the College of Veterinary Medicine, and collaborators at Cambridge University and the National Institutes of Health have uncovered a previously unknown aspect of how DNA double-stranded breaks are repaired.

A large protein kinase called DNA-PK starts the DNA repair process; in their new report, two distinct DNA-PK protein complexes are characterized, each of which has a specific role in DNA repair that cannot be assumed by the other.

“It still gives me chills,” says Meek. “I don’t think anyone would have predicted this.”
