Where does gene editing go next?

We now know the basics of a healthy life. A balanced diet, regular physical activity and reduced stress can help us avoid heart disease, the world’s biggest killer. What if you get the vaccine too? Not a typical vaccine – an injection that alters your DNA for life-long protection?

This view is not far-fetched, researchers say. Advances in gene editing, especially CRISPR technology, will soon make this possible.

Gene editing may eventually be poised to go mainstream, treating many diseases and conditions, not all of which are genetic. In the future, we can use this same approach to protect people from high blood pressure and diabetes and dramatically improve their quality of life. Read the full story.

These scientists inserted the alligator gene into catfish using CRISPR

What happened? Millions of fish are farmed in the United States every year, but many of them die from infection. In theory, genetically modifying fish with genes that protect them from disease could help solve the problem. A team of scientists attempted to do just that by inserting an alligator gene into the dogfish genome.

Why the alligator gene? According to a team at Auburn University in Alabama, the alligator gene encodes a protein called cathelicidin, which has antimicrobial properties. In theory, this could make animals that have had the gene artificially inserted into their genomes resistant to disease.
