To Treat Genes, Apply Directly to the Skin
Scientists have shown that they can deliver gene-regulation technology directly through the skin with regular moisturizers. This first-time demonstration of the method indicates its great potential for life-saving therapies for skin cancers, say the researchers, who were led by a physician-scientist and a chemist from the fields of dermatology and nanotechnology. The Northwestern University team's approach takes advantage of drugs consisting of novel spherical arrangements of nucleic acids. These structures, each about 1,000 times smaller than the diameter of a human hair, have the unique ability to recruit and bind to natural proteins that allow them to traverse the skin and enter cells.
