Biologists from the University of South Korean "Yonse" created an artificial virus that can penetrate the cancer cells and deliver them antitumour means - drugs and genes.The team of researchers under the leadership of Lee Myung-soo has used a new strategy, which enabled them to create artificial viruses certain shape and size. Korean biologists used as a template protein structure, similar to the tape. It joined "protein hands" who "kept" short cycle of so-called RNA interfere. This type of RNA plays a key role peculiar - it can "turn off" genes in the cell, which is suitable. As a result, the corresponding protein synthesis is blocked, which is a promising technology in gene therapy. In addition, scientists have shown that they have created virus can penetrate the nucleus of cancer cells, where it is "broken" DNA, and block their further growth.
