While cancer treatments based on RNA interference are seen by some cancer researcher as the new frontier in cancer therapy, researchers have struggled to find an efficient delivery method for the drugs that also keeps the siRNA safe from being broken down before it reaches its target. Now, researchers at MIT may have solved the problem, according to a university press release. In a letter published recently in Nature Materials, the team describes its novel delivery system in which RNA is packed into "microspheres so dense that they withstand degradation until they reach their destinations," the blog says. "The new system … knocks down expression of specific genes as effectively as existing delivery methods, but with a much smaller dose of particles."
