  2. 2. Gene Therapy – One World Essay 27th 09 2010 By: Christine Chiang Gene therapy refers to the gene technology, scientist are planning to do a lot of experiment to develop the gene therapy to useable for everyone in the future. However, for now scientists are trying to inject genes directly into human cells, but only focusing on the wide range of diseases, including those resist conventional treatment, foe examples, cystic fibrosis, haemophilia, muscular dystrophy and sickle cell anemia. There are many important points that people should go through before the gene therapy has developed too much. The application of science, the benefits and limitations, and the one world issues are going to be the three main topics that this essay tells about, which helps people into a better understanding of the gene therapy. The process of doing gene therapy is very complicated and in the technology today it still carries out a number of dangers. Even though it carries out some danger such as, leukemia, but there are still some causes that doctors suggest people to use gene therapy for treatment during these days. Normally doctors suggest the sickness to use gene therapy only when they are in a very bad condition, where there are no other better choices. Gene therapy requires Figure 1: Admin ( 25th Sept 2010) a gene delivery system, which is able to This is a diagram showing how does a vector transfer the gene to carry DNA to the body. the patient’s cells. First, the gene therapy is done by taking out the cell for the patient’s body that includes defective allele in it. Then the scientists needed inject normal allele back in to the patient’s body, but in order for the body to accept the gene, scientists usually need a carrier for introducing the DNA to the body. Those carriers are known as vectors. So far there are only 4 different types of vectors that can be used for gene therapy, retrovirus, adenovirus, liposome, and naked DNA. The scientists need to make a copy of normal people’s allele, insert with the DNA, which become recombinant DNA, and then insert it into the viral vector. After that the cells that include defective allele are infected with virus containing the recombinant DNA. Moreover, viral DNA will carry the normal allele into the

Gene therapy need to go through a long process of taking out isolated body cells, recombinant DNA, and finally put it back into the body. There are some benefits and limitations that might happen after the gene therapy. With gene therapy people can prevent their children from the diseases by changing their genes. Gene therapy will probably be the best choice in the future for people to obstruct from the hereditary diseases such as cystic fibrosis, haemophilia, AIDS, and cancer. For example, in September of 2001 there are more than 3500 patient that done gene therapy mainly affected by cancer (63 %), genetic (13 %), cardiovascular (8 %) or infectious (6 %) diseases (Position paper on social, 2010). In the future gene therapy might be allowing for people parents to choose the skin colour, personality, intelligence quotient etc by changing the DNA before the baby is born, which helps their child to get a high position in the society, but this can also become a limitation. As the gene therapy has developed too much and become a treatment that people are able to use and waste the resources for some unnecessary situations, such as choosing the unborn baby’s gender, hair colour, eye sight, personality etc, meanwhile it will also make people similar to each other. An other limitation is doing gene therapy will change the DNA of that person, which means the part of the body that person did gene therapy on won’t have the original DNA that was given from his/her parents, so there will have less connections between the child and parent. Also, there are still certain dangers for children to do gene therapy. From the technology we have so far Doctor wouldn’t suggest kids to take gene therapy unless they are in serious ill and unable to be control by the cure of treatments. With the new technology of the gene therapy it might cause some serious global issues such as ethical and economic. Gene therapy have a big affect on the ethical of the one world issue, which means the questions of right and wrong will come in to people’s mind. To recommend who a person is was by looking at the DNA, personality etc, that was given from the parents, and to change DNA you will no longer be who you are that you suppose to be. On the other hand don’t find anything wrong about changing the DNA, for example, people can dye their hair, but instead why not change the hair colour from DNA, children go to school to get education, but not changing the DNA at the beginning for a high intelligence quotient. Another ethical problem that might happen is if parents make their children perfect then in the future world there in on more not perfect person, which also might mean that everyone will be similar to each other, and maybe if their parents have chosen the same personality, skin, hair colour, height etc, then those people might be exactly the same. The other important one world issue for gene therapy is economic. Today, it caused a lot of money in order for people to have gene therapy treatments, but the number of people that couldn’t pay for this is very high. In some countries governments are helping the patients for few percent of the payment, but for a lot of patients the payment is still too high for them to offer, especially in the European countries.
  4. 4. Overall, the gene therapy is not in a stable situation where people are able to take this treatment because of the disadvantages and the one world issues that the governments still need to work on. Although, there are some benefits to gene therapy, which gives a good start for the scientist to work on. I think in the future when gene therapy is available for people to change skin colour, personality, intelligence quotient etc, government should make some related lows to stop, and not allow people to do that, otherwise there won’t have differences from each other. I think it is better for people to develop their knowledge in school instead of taking the gene therapy for high intelligence quotient because we are able to learn and went through the process ourselves, which are more natural and we shouldn’t break the natural process.
