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).

- 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....

- What is Gene Therapy and what is it used for. Gene therapy (otherwise known as somatic gene therapy or therapeutic gene therapy) is a process that is used to correct defective genes responsible for development of various diseases. (www.accessexcellence.org/RC/AB/BA/Gene_Therapy_Overview.php) There are two main types of gene therapy; somatic (body) cell gene therapy and germ line gene therapy. As it suggests, somatic gene therapy is correcting the faulty genes of normal body cells. Germ line therapy is altering genes in gametes.... [tags: Medical, Genetics, Medicine, DNA]

- There are opposing viewpoints on the incorporation of gene therapy into modern medicine. Many scientists and individuals from the public find genetic therapy to be unethical. In contrast, others see it as a revolutionizing technology that will change medicine and produce treatments and preventions to genetically inherited diseases. Reece briefly mentions the challenging decisions that accompany technological advancements. The ethical concerns that arise with gene therapy include; is the usage of DNA technology adequate to determine if people have genes for inherited diseases, should the tests be voluntary, should genetic testing be obligatory (Reece, et al....

- Pros and Cons of Gene Therapy Gene therapy is thought of by some people as an terrific discovery that could greatly improve the human population and also give people with certain disabilities some glimmer of hope. And on the other side of the coin there is some people that think we have no business playing God. They feel that playing God may possibly cause devastating effects to the human gene pool and may also led to misuse. Merriam-Webster’s Collegiate Dictionary defines gene therapy as the insertion of normal or genetically altered genes into cells usually to replace defective genes especially in the treatment of genetic disorders....

- There are many people in this world with disorders and diseases that disrupt the balance of crucial proteins in the human body necessary for proper function and survival. Without these important proteins such as enzymes, humans are bound for disability and/or death. Recently, Gene Therapy has been more researched and studied, and is currently being improved and developed for the benefit of mankind. However, with the rise of this new and effective type of therapy, there comes a heavy topic of debate over the ethical issues in bringing this revolutionary research into play....

- ... The purpose of Human Germline Genetic Modification (HGGM) therapy is to permanently modify the genetic makeup of a gene, which would pass to future offspring. This could ultimately change the appearance of future generations and not just focus on curing diseases. There are no reports that HGGM therapy has been performed on humans. There are a lot of unknowns with this type of therapy regarding side effects and future development of the fetus, however; with the advancements in reproduction technologies and stem-cell research, scientist may be closer to being able to perform this type of therapy....

- In September 14, 1990, a four-year-old girl named Ashanti De Silva with ADA (an inherited immune system disease) sat quietly at the National Institutes of Health in the United State, and she was the first person to get a new but controversial called Gene Therapy. The operation was only a temporary success when the case of “Jesse Gelsinger” happened. Gene Therapy is a remedy that introduces genes to target cells and replaces defective genes. It can cure diseases which cannot be cured by traditional medicines.... [tags: Medical Technology ]

- The Pros and Cons of Gene Alteration Abstract A new epidemic in human reproduction is slowly sweeping the earth, and it is known as human gene alteration. It gives parents the ability to decide their babies' sex, hair color, or even eye color. Creating these so called "designer babies" seems like the perfect way to have the child you have always dreamed of. But is this a moral way to go about reproduction. Is it fair to these children to mess with their genes just for your own satisfaction of having the perfect baby.... [tags: Exploratory Essays Research Papers Science]

- A New Future: Gene Therapy Imagine a world where a person could change his or her genetic structure and redirect the future course of evolution in their child and themselves. Through gene therapy this is a very real possibility. In the future it could be just as easy to change your physical or mental health as it is to get flu shot now. But the affects of gene therapy are long lasting and could affect your future offspring as well as your own health. What is gene therapy. First discovered in the middle of the 1970's researchers were able to isolate certain genes from DNA.... [tags: Genetics Science Technology Essays]

- Somatic Gene Therapy To a parent, the thought of their child having a severe, yet rare genetic disease brings guilt, sadness, and responsibility to an aching heart. Parents who see their child pass through life with the weight of a terminal illness often wish in their hearts that the curse had been placed upon them rather than their child. To some, the thought of the old cliché "no parent ought to see their child die" seems to swim endlessly in their mind. The hope for a cure fills the hearts of many waiting on the edge of their seats in hopes for a better quality of life for themselves, loved ones, and human kind....
