Gene therapy has been a very controversial issue since its origin in 1990 when A four-year old girl became the first gene therapy patient. She has adenosine deaminase (ADA) deficiency, a genetic disease which leaves her defenseless against infections. Gene therapy involves substituting normal genes for the genes associated with a disease or disorder otherwise altering a person’s genetic makeup. Each gene has a specific code for what it is supposed to do. So, on top of our genome, we have a complex epigenome. These epigenomes consist of all kinds of different markings. The genes themselves are not altered when epigenetic effects occur; however, their effect is altered. Gene therapy can be categorized in to two different types—somatic cell therapy and reproductive cell also referred to as germline therapy. Somatic cells involves targeting …show more content…
One con of gene therapy is that it may be used to enhance and modify human capabilities. If this was feasible, standards for normal human life would be altered for good. Even if certain countries experimented with this form of therapy, they could create unstoppable armies much like in those movies we’ve seen on the big screen. If gene therapy was performed to a certain degree, it possibly could permanently change the human gene pool. Another thing would also be this treatment therapy may possibly be for the rich only, and could make the rich richer and the poor poorer, indefinitely. While the most common choice as a vector, using the virus for such a purpose is not guaranteed. There’s an exact point in the host genome where the right should be brought in and there are no assurance that the viral enzyme responsible for this step will be able to bring in the right genes at the exact point in the host genome. If there’s an error in the process, the results could be bring about severe disorders. In addition, the body may destroy the vector perceiving that it is a foreign
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.
Gene therapy is reinserting certain genes that helps deal with genetic diseases. There are three basic forms of this gene therapy. The first is Gene Inactivation Therapy in which the transferred gene neutralizes the proteins and evens out the amount or rids of the defective proteins. Another type is Gene Augmentation Therapy where the original form of the gene or the normal form of the gene is inserted into one of the cell’s chromosomes. This procedure is used normally when a gene with little activity or a deleted gene is the cause for the genetic disease. The third type of gene therapy is Gene Replacement Therapy. This form is used when the genetic disease involved specific genes that are necessary for proper functioning. The normal gene being put in place of the mutant gene accomplishes this form of gene therapy.
Gene therapy is an experimental technique that allows doctors to insert a gene into a patient’s cell rather than using drugs or surgery. Gene therapy is a process of which defective or undesired genes in the body with “normal” genes. A vector is re-engineered to deliver the gene to a target cell. Then the gene is transferred to the cell’s nucleus and must be activated in order to function. The main focus of gene therapy is to replace a lost or improper gene with a new functional copy into a vector that is inserted into the subject’s genome by way of penetrating its DNA. Gene therapy can be done outside of the body known as ex vivo by way of taking cells form patients bone marrow or blood and then growing them in a laboratory. Thus the corrected copy of the gene is inserted into the cells before being put back into the body. Gene therapy can also be done in vivo which can be done directly to the patient’s body. The word gene therapy really defines the management of genetic information that is encased in the cells, however, in most recent procedures the available technology is closely related in adding new genetic information, and many researchers favor the term gene transfer rather than gene therapy to mirror the reason that the purpose of gene work cannot always be therapeutic.
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.
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 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.
One of the most necessary uses of genetic engineering is tackling diseases. As listed above, some of the deadliest diseases in the world that have yet to be conquered could ultimately be wiped out by the use of genetic engineering. Because there are a great deal of genetic mutations people suffer from it is impractical that we will ever be able to get rid of them unless we involve genetic engineering in future generations (pros and cons of genetic eng). The negative aspect to this is the possible chain reaction that can occur from gene alteration. While altering a gene to do one thing, like cure a disease, there is no way of knowing if a different reaction will occur at the cellular or genetic level because of it; causing another problem, possibly worse than the disease they started off with (5 pros and cons of gen. eng.). This technology has such a wide range of unknown, it is simply not safe for society to be condoning to. As well as safety concerns, this can also cause emotional trauma to people putting their hopes into genetic engineering curing their loved ones, when there is a possibility it could result in more damage in the
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 aim is to decrease the fear of a brave new world and to encourage people to be more proactive about their health. It [Gene therapy] will help humans become better physically and even mentally and extend human life. It is the future” (Hulbert). Dr. Hulbert, a genetic engineer, couldn’t be anymore right; more time, money, and research needs to be put into gene therapy and genetic engineering, since it can cure certain illness and diseases that are incurable with modern medicine, has fewer side-effects than conventional drugs or surgery, and allows humans to be stronger physically and mentally at birth. Gene therapy or genetic engineering is the development and application of scientific methods, procedures, and technologies that permit direct manipulation of genetic material in order to alter the hereditary traits of a cell, organism, or population (NIH). It essentially means that we can change DNA to make an organism better. Genetic engineering is used with animals and plants every day; for example with genetic...
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.
Genes are made of DNA – the code of life (Gene Therapy- The Great Debate!). The changes in genes may cause serious problems, which we called genetic disorder. In theory, the only method to cure genetic disorders is gene therapy, which basically means the replacement of genes in order to correct the loss or change in people’s DNA. Although gene therapy gives patients with genetic disorders a permanent cure, it is controversial because it has safety and efficacy problems, and raises ethical issues.
Due to the fact that the field of biotechnology is very serious and potentially dangerous, rules must be set down in order to keep the research in check. The high risk research of genetic therapy needs guidelines that have to be followed in order to keep the study just. The articles that are discussed in this essay focus on ethical issues and ideas that should be followed in the field in order to keep research safe and valid.
...ring deadly diseases and preventing abortions. In order for gene therapy to one day become effective much more research needs to be done to discover the consequences of altering specific genes. Also the technology of gene therapy needs to be cost effective so people who need help are able to get help. In the end gene therapy in humans needs to come a long ways before it will be widely accepted but there is great potential in the technology and it needs to be pursued.
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”.
