In September 14, 1990, an operation, which is called gene therapy, was performed successfully at the National Institutes of Health in the United States. The operation was only a temporary success because many problems have emerged since then. Gene therapy is a remedy that introduces genes to target cells and replaces defective genes in order to cure the diseases which cannot be cured by traditional medicines. Although gene therapy gives someone who is born with a genetic disease or who suffers cancer a permanent chance of being cured, it is high-risk and sometimes unethical because the failure rate is extremely high and issues like how “good” and “bad” uses of gene therapy can be distinguished still haven’t been answered satisfactorily. Gene therapy gives people who suffer from genetic diseases a chance to lead a normal life. Dangerous diseases, such as AIDS, SCID, Thalassemia and ADA can be cured successfully. In September 5, 2006, two people with advanced melanoma received Gene therapy and they got recovery soon. This is a breakthrough in cancer gene therapy. Gene therapy uses patients own cells to cure diseases, and, therefore, no rejection to their bodies. Furthermore, patients could get permanent cure from gene therapy without recurrence. Despite being magical of gene therapy, it is high-risk. Few people got benefits from it, and it has a low rate of success. Prior to the human trial, Batshaw and Wilson had done experiment on animals to ensure the safety. Over 20 experiments have been done on mice but only 12 of them survived at last (Sophia, M. and Kolehmainen, J.D., 2000). More seriously, complicating diseases, which can be more dangerous than genetic diseases, might set in during the treatment period. In December 200... ... middle of paper ... ...s of gene therapy is that the mortality rate is very high. This is because Immune system may attack cells and cells may attack vital organs. Furthermore, ethical issues should be dealt in a positive way. The technological institute has to reduce the unnecessary expenses of the treatment. I highly suggest the government investing more money on the development of gene therapy. To conclude, although gene therapy can cure a wide variety of diseases which cannot be cured by traditional medicine, and patients can get permanent cure without rejections, it can be high-risk and immoral. The negative effects of gene therapy lead to the shrink of the number of volunteers, and many trials have been forced to cease. The Gene therapy's potential to revolutionize medicine in the future is exciting, and hopes are high for its role in curing and preventing childhood diseases.
Gene therapy is the application of the technique where the defect-causing "bad" genes are replaced by correct "good" genes. The idea of gene therapy is to treat the disease by correcting the "bad" DNA (Deoxyribonucleic acid) rather than the current me thod of providing drugs, or proteins not produced by the defective gene. Gene therapy addresses the problem first hand by directly working with the genetic information causing the disease. From the book Shaping Genes, Dr. Darryl Macer says "It is like f ixing a hole in the bucket, rather than trying to mop up the leaking water." There are two kinds of gene therapy, somatic cell gene therapy and germline gene therapy.
In this paper, I will argue that genetic therapies should be allowed for diseases and disabilities that cause individuals pain, shorter life spans, and noticeable disadvantages in life. I believe this because everyone deserves to have the most even starting place in life as possible. That is no being should be limited in their life due to diseases and disabilities that can be cured with genetic therapies. I will be basing my argument off the article by “Gene Therapies and the Pursuit of a Better Human” by Sara Goering. One objection to genetic therapies is that removing disabilities and diseases might cause humans to lose sympathy towards others and their fragility (332). However, I do not believe this because there are many other events and conditions in society that spark human compassion and sympathy towards others.
There have been four somewhat recent successful gene therapy treatments. The four deal with correcting hemophilia, bone marrow transplants, skin cancer, and vessel growth. In the success with the bone marrow transplants, French researchers collected bone marrow cells from patients, used gene therapy to correct the bone marrow, and then returned the bone marrow to the patient. This was 80% successful as reports 16 months after the transplants showed. Squamous cell carcinoma, skin cancer of the head and neck, was treated using gene therapy as well. The fourth trial was where DNA was used to carry a substance that stimulates blood vessel growth to damaged heart tissue and in this trial there was much success noted.
Just as there are different types of people who look at one glass of water and describe it as half full or half empty, the public has many different views on the future of our society. Gene therapy is also a glass that can be viewed in different angles – different perspectives. Some say it has great potential to shape the ideals of our future, while others believe it signifies intolerance for disabilities, imperfections that supposedly deplete from a person’s interests, opportunities and welfare (quoted by Peter Singer, xviii). This global issue has brought people with different opinions in the open, arguing their views using history, morality and foresight.
It will then inform the reader of the effects it will have on our society. Diseases like cancer, AIDS, cardiovascular disease, cystic fibrosis and Alzheimer’s could potentially be cured (American Medical Association). However, serious risks can be associated with gene therapy. If a gene is added to the DNA, there is a possibility it may be inserted in the wrong place, which can lead to other harmful effects (Gene Therapy and Children). However, it also has the ability to positively affect patients lives.
Gene therapy works in three ways; it works to replace a missing or defective gene with a normal one, replace a faulty gene so that it will function properly and it works to activate and deactivate a gene, allowing it to “switch” on and off. Gene therapy is done by the deliverance of a gene to a cell via a carrier, or vector, such as a virus. Scientists lean more towards using a virus because they can seek out particular cells and transfer pieces of deoxyribonucleic acid into them. Scientists also take advantage by deactivating their harmful characterizes and modifying them to carry particular gene into designated cells. After gene therapy is done, the genes can then stimulate the production needed for standard functioning, allowing that gene to return to its previous normal state. Therefore, if a patient were to be in the beginning stages of cancer, gene therapy would seek out the cancerous gene and replace it with a healthy one and minimizes the disease from
In the past 40 years, scientists have developed and applied genetic engineering to alter the genetic make-up of organisms by manipulating their DNA. Scientists can use restriction enzymes to slice up a piece of DNA from an organism with the characteristics they want and spliced (joint) to a DNA from another organism. DNA that contains pieces from different species is called recombinant DNA, and it now has different genetic material from its original. When this DNA inserted back into the organism, it changes the organism’s trait. This technique is known as gene-splicing (Farndon 19).
General dangers of the techniques of gene therapy are a large concern. One problem is that the new gene may be inserted in the wrong location in the DNA. Experiments with rats showed this could cause cancer or other damage. In addition, when DNA is directly injected into a tumor there is a chance that the DNA could be introduced by mistake into reproductive cells, producing changes in offspring. The consequences of this are discussed in more detail later on. Another disturbing thing to think about when pondering the safety of gene therapy is the fact that once gene therapy has taken effect it cannot be stopped and is irreversible. It is not like drugs, the genes cannot be stopped from multiplying.
The use of gene therapy to prevent illness and disease by changing a person's genetic makeup is a good use of science. Gene therapy is an approach in science to treat, or ultimately prevent disease by changing the expression of a person's genes. The way a gene is expressed is something like a person's hair color. Gene therapy is still in its very early stages of development. Any gene therapy that is being worked on today is still in its experimental stages. It will not be used in humans for extensive use for a while. The only humans are ones who are in clinical trials ("Gene Therapy").
In summary, gene therapy clearly has benefits if it successfully treats diseases and allows people to lead normal and productive lives. There are still some problems associated with gene therapy but hopefully research can overcome these problems and make gene therapy more reliable and cheaper.
Since its inception, gene therapy has captured the attention of the public and ethics disciplines as a therapeutic application of human genetic engineering. The latter, in particular, has lead to concerns about germline modification and questions about the distinction between therapy and enhancement. The development of the gene therapy field and its progress to the clinic has not been without controversy. Although initially considered as a promising approach for treating the genetic of disease, the field has attracted disappointment for failing to fulfil its potential. With the resolution of many of the barriers that restricted the progress of gene therapy and increasing reports of clinical success, it is now generally recognised that earlier expectations may have been premature.

In an article titled “The Ethical Implications of Gene Therapy” the group of advisers on Ethical Implications of Biotechnology of the European commission states issues and rules that should be abided by, along with beliefs on the direction of biotechnology. At its present stage, biotechnology focuses on serious diseases which are incurable at the moment, however through this research treatment for these diseases could be found. The group of advisers feel that there should be levels at which research should focus on, instead of jumping into it all at once. Basic research should be carried out prior to clinical trials, and then move on to biotechnology. This can be done by supporting research actions, organizing training and exchange programs or any other appropriate means. Gene therapy protocols require that ethical evaluation consists of processes assuring quality, transparency and efficiency without delays of treatment to the patients who need it. This is crucial because an inefficient, poor quality treatment could cost someone their life. The group also feels that gene therapy research should be restricted to serious diseases for which there is not a current treatment. Expanding research to other things could be done if a medical evaluation calls for it. Equal access should be assured to all researchers within the European Union, thus sharing information and helping to improve orphan drugs. This could also save time and money. In order to insure the public of what is going on, conclusions of evaluations should regularly be published to encourage public debate. The public is not usually informed much about genetic therapy and many people have the wrong idea about it. Should reports be published more often, there will be less public confusion and ridicule.
Position Paper: Gene Therapy in Humans. Advancements in science and medicine are usually accompanied by a myriad of ethical and moral implications. The fairly recent advancement in genetics, called gene therapy, is no exception to the baggage of polarizing views that come with new technology. Gene therapy is an extremely hot topic in both the scientific world and everyday life. New technology, discoveries, and breakthroughs are rapidly occurring in the field every day.
What are the risks and what are the possible benefits? Currently, gene therapy is one of the only ways to change the genetic makeup of an animal or human. Also, the chance of gene therapy being successful in animals is fifty percent, while in humans it is five percent. Human Genetics Alert believes “Once we begin to consciously design ourselves, we will have entered a completely new era of human history, in which human subjects, rather than being accepted as they are, will become just another kind of object, shaped according to parental whims and market forces”.
