Gene Therapy
Deoxyribose nucleic acid (DNA) is known as the code of life. Its discovery in 1953 by James Watson and Francis Crick opened a pathway into a revolutionary new science known as genetics. In fifty years, biological research has evolved by leaps and bounds because of the identification of this six-foot long strand of molecules. Many people, however, do not understand the infinite possibilities that the study of genetics can unveil to the world. Many of these pathways have been investigated and studied, and results have come to some while failures have come to others. One of the most recent, brilliant technologies to be brought to life from the study of genetics is gene therapy. As Panno (2004a) indicates, scientists have begun to imagine the possibilities of actually changing a living organism’s DNA, possibly making the specimen stronger, healthier, and more resilient to deadly diseases (n. pag.). Many dilemmas, most ethical and religious, arise from this thought process, but the fact that it is possible remains. Through gene therapy, scientists have discovered a plethora of ways to cure some genetic diseases; but these trials have not been without faults that come with any groundbreaking technology.
DNA
To first understand what gene therapy is, the science behind it, genetics, must be understood. DNA, while small, is a very complicated structure. Formed in a double helix, the tiny molecular strands wind around for over 6 feet inside each and every cell of the body. There are 4 molecules that connect together to create each base pair of DNA- the actual code of the strand. As explained by Hopkins (2006), these molecules, also known as nucleotides, in two pairs of Guanine and Cytosine, and Thymine (which is replaced b...

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.
... fight the disease. It is crucial that regulation be a necessary component of gene therapy research and applications. In hopes that the government can regulate and can receive this treatment, not restricting it to people that has serious genetic diseases. Gene therapy will change the field of medicine from what it is today. As scientist discovers more genes and their functions, the potential of this treatment is limitless. Though gene therapy is an auspicious treatment choice for numerous diseases (including inherited disorders, some types of cancer, and certain viral infections), the procedure remains precarious and is still under study to make sure that it will be safe and effective. Thus government regulators and scientist must take a lead role in adopting a practical approach to address these issues and determining the correct procedures for dealing with them.
Human gene therapy is a method used in the medical field that treats diseases at a molecular level, by solving the source of the problem; our genes. Today, diseases and disorders are commonly treated by solving the symptoms, the surface of the problem. Many disorders and diseases are caused by defective proteins and within those defective proteins are damaged and defective genes. These defective genes can be treated through gene therapy. Gene therapy is not new and has been developed and improved by researchers for the past couple years. Being an experimental technique, gene therapy also has its pros and cons, but so far is showing positive and rising success rates.
In the modern world humans have been able to design and create nearly anything, most to aid us in our daily lives and improve our standard of living. It is only inevitable that eventually humans would take our superior knowledge and skill to manipulate life itself and change our genome to produce a healthier and even more superior human standard of life. In recent years discussion about gene therapy has changed into a promising possibility to treat many of our common human diseases and disorders. Although gene therapy might be the answer to many problems, it has been met with a number of logistical and ethical hardships. With the prospect of being a treatment for inherited genetic disorders, cancers, and viral infections, gene therapy seems like the logical fix-it-all bandage that many people would benefit from.
Gene therapy is a technique which has developed in the wake of recombinant DNA (rDNA) technology. It is a process which results in the correction of a genetic disorder by the addition of a piece or fragment of DNA into the genetic material of a living, functioning cell. A mere thirty years ago this concept belonged to the realm of the human imagination made manifest in the works of science fiction. Today it belongs to the realm of the human imagination made manifest in the works of science, period. It is mind boggling to try to comprehend the far reaching effects of gene therapy. How is it affecting society? Who will benefit from its use? Should it be used at all? Should research continue? How do we answer all of these questions? The answers are not readily available, nor are they black and white, but an attempt at finding some solutions must be made. Before exploring this line of thought further, a basic understanding of the technical aspects of gene therapy is essential.
In this paper, I will negatively expose Walter Glannon’s position on the differentially between gene therapy and gene enhancement. His argument fails because gene therapy and genetic enhancement is morally impermissible because its manipulation and destruction of embryos shows disrespect for human life and discrimination against people with disabilities.
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.
"What's the worst that can happen to me? I die, and it's for the babies," said Jessie Gelsinger as he left for the hospital to receive gene therapy treatment. (Stolberg) People risk their lives everyday in the name of science. One such science that people have recently been drawn to is gene therapy. Although, gene therapy may be new and exciting and it may be helping to find cures to diseases we only dreamed of curing, we have to remember it is dangerous. It needs to be done with much supervision. Every new step we take in the advancement of gene therapy should be thought over because the consequences could reach farther then we ever believed they could. There are so many dangers of the techniques used that can lead to consequences as serious as death. The government imposes many guidelines, and it needs to stay that way. The biggest dangers, however, may be in what is to come.
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.
Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
The American Cancer Society publishes current advances made in cancer research on their website. Many of the exciting discoveries about how best to treat the disease focus on the genetic aspects associated with certain types of cancer. In addition, treatments aimed at genetic solutions to cancer may be more effective and may cause fewer adverse side effects than traditional cancer treatments (American Can...
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.
