Genes Controlled with Light

Scientists have found a way to use light to control blood sugar in mice.

Using a protein from the human retina, researchers in Switzerland have developed a method to control the expression of target genes with light. The scientists say the technology could be employed in the near term to boost the production of biological drugs, such as those for cancer, by enabling precise control over protein production. In the long term, cells engineered to carry the light-sensitive switch could be implanted into patients to produce a missing hormone, such as insulin, on demand.
