When in 1904 Avery (OT Avery 1877 ~ 1955)’s the pneumococcus transformation experiments firstly found that DNA is the carrier of genetic information. (Baruch S, Huang S, Prichard D, et al., 2005) Many gene-related academic subjects have poured out. Through them, gene therapy which has the closest link with human’s lives is the most controversial subject. Although gene therapy gives us hope of many diseases which seems impossible to be cured before, but the drawbacks of gene especially the cons from ethical like the death caused by gene therapy, the evolution problems caused by DNA exchange and the censorship of the experiment of gene therapy. As a result, whether to continue developing gene therapy need to be cautious.


Admittedly, the technology of genetic therapy does bring hope to some diseases like lung cancer which are considered as incurable disease. There are also some successful medical examples. In 2006, the U.S. National Cancer Institute found a way to identify and attack cancer cells by changing the genes of patient's immune cells. After the first clinical trials, two patients with advanced melanoma skin cancer have been cured. (Baruch S, Huang S, Prichard D, et al., 2005) Coincidentally, in 2008, the scientists in German found that hemophilia and other genetic diseases can be cured in theory through gene therapy. (Baruch S, Huang S, Prichard D, et al., 2005) The most important advantage of gene therapy is that the disease once has been cured by gene therapy will have very low possibility to relapse. That is because all the species on the earth follow the principle of base pairing. So the genes of the nucleus has nearly no odds to produce rejection (Rifkin, J., 1993).
