- RNAi Shows Promise In Gene Therapy, Stanford Researcher Says
Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique. Since then he has used RNAi gene therapy to effectively shut down the viruses that ca ...
