Human Gene Therapy
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.
Gene therapy works by introducing new and functioning genetic material to damaged genes to help it function and to produce beneficial proteins. If a gene is inserted directly into a cell, it usually will not function. So to complete this task, a vector, a modified virus is used to carry and deliver the new gene. There are two different categories of vectors than can be utilized in this process; recomb...
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.
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.
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
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.
Genetic engineering is now being used to create new medicines and therapies for many disorders and diseases, and also to improve agricultural plants and animals to produce bigger yields or enhanced nutrient composition and food quality. In Gene therapy, copies of healthy human genes produced in bacteria can be inserted into human cells with defective or missing genes, to fix the problem. Gene therapy is promising because it can use to treat genetic

Tim was diagnosed with a rare and deadly disease this morning. He is only five years old with the rest of his life ahead of him. It isn't his fault that he received this disease or even his parents'. This disease comes out in anyone's body that has a defected gene. The disease has made Tim live in a sanitized bubble the last year because of the fear that he might catch any common bug and die. He has severe combined immunodeficiency, or SCID. The disease lacks a gene in charge of the body's immune system called adenosine deaminase. Tim could be helped through a process called gene therapy, but he won't because there is too much debate on the ethnicity of gene therapy; too much even to save his life.
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.
[Cover: discussion about how risks are balanced during risk assessment, why this is a difficult task -> proposing a set of principles and practical measures that might assist both researchers and patients, to enable more informed decisions about risk]
“UC Berkeley researchers have made a major improvement in CRISPR-Cas9 technology that achieves an unprecedented success rate of 60 percent when replacing a short stretch of DNA with another”(Antonio Carusillo, PhD Candidate in Genetic Engineering (Marie Curie) at University of Freiburg (2018-present). This statistic shows that there is more of a chance to success but there is a chance to fail 40 percent but overall it will succeed which is why people are lenient about will it actually work or not, but as technology get better so will treatments to cure hard to pinpoint disease such as cancer, zika, or leukemia. Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism's DNA.
Human Genetic Engineering: Designing the Future As the rate of advancements in technology and science continue to grow, ideas that were once viewed as science fiction are now becoming reality. As we collectively advance as a society, ethical dilemmas arise pertaining to scientific advancement, specifically concerning the controversial topic of genetic engineering in humans.
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.
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.
