CRISPR-Gold
Gene Editing: Gold Nanoparticle Delivery Shows Promise
Posted on by Dr. Francis Collins
About a month ago, I had the pleasure of welcoming the Juip (pronounced “Yipe”) family from Michigan to NIH. Although you’d never guess it from this photo, two of the Juip’s five children—9-year-old Claire and 11-year-old Jake (both to my left)—have a rare genetic disease called Friedreich’s ataxia (FA). This inherited condition causes progressive damage to their nervous systems and their hearts. No treatment currently exists for kids like Claire and Jake, yet this remarkable family has turned this serious health challenge into an opportunity to raise awareness about the need for biomedical research.
One thing that helps keep the Juips optimistic is the therapeutic potential of CRISPR/Cas9, an innovative gene editing system that may someday make it possible to correct the genetic mutations responsible for FA and many other conditions. So, I’m sure the Juips were among those encouraged by the recent news that NIH-funded researchers have developed a highly versatile approach to CRISPR/Cas9-based therapies. Instead of relying on viruses to carry the gene-editing system into cells, the new approach uses tiny particles of gold as the delivery system!
