Imagine that one day your son or daughter get diagnosed with a terminal disease and the doctor tells you that you can try to use Gene Therapy to save them except it is an experiment so it might be risky. Even though this might not happen because it is a new technique and isn't funded for hospital use you can still have knowledge about it if you read this paper.
Gene Therapy is a process where they take healthy DNA or Stem Cells and use them on damaged or infected versions to make them healthy again. You might not know much about it because it doesn't have as much funds as many other things but it helps people get better in less time. I believe with Gene Therapy we can cure many of the illnesses in the world.
Treatments that include Gene Therapy are limited but here are a few. A tool called the "Skin Gun" uses healthy skin stem cells and when you spray them on burned cells it heals them in a matter of 3-4 days. In normal burned skin treatment they "grow" skin which takes a week or two. Scientists take DNA out of your body or another body and change them outside the body and then put...
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.
It was in the 1980’s that scientist began looking at alternative ways of treatments, one is gene therapy. Scientist would insert human genes into a bacteria cell. Then the bacteria cell would transcribe and translate the information into a protein. Once that is done the scientist would then introduce the protein into human cells. Gene therapy can be simply viewed as inserting bits of foreign DNA into a patient’s tissue in hope...
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.
Over 40 years ago, two men by the names of James Watson and Francis Crick discovered deoxyribonucleic acid, or DNA. DNA is hereditary material in humans and almost all other organisms (What is DNA?). From this finding, gene therapy evolved. Today, researchers are able to isolate certain specific genes, repair them, and use them to help cure diseases such as cystic fibrosis and hemophilia. However, as great as this sounds, there are numerous ethical and scientific issues that will arise because of religion and safety.
Although the highly technical aspects of human gene therapy are somewhat complex, the basic concept is very straight forward. The goal of gene therapy is to correct mistakes that have occurred within the genetic material, or DNA, of the living cell. In very simple terms, DNA is often thought of as the "language" of the biological functioning of organisms. This language is organized by letters (nucleotide pairs), words (codons), sentences (genes), and books (genomes). Before being able to repair the damaged or defective genetic material, the location of the gene or genes causing the dysfunction in the individual must be determined.
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 is a new approach to treating diseases by changing a person’s genes. Not only does gene therapy hope to be used to cure genetic diseases, but there are also promises of disease prevention. There are two types of gene therapy somatic and germline. Somatic gene therapy hopes to change the gene of the patient, but this change of expression in the gene will not be passed down to the next generation.
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.
"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...

Gene therapy is a method used by doctors that ‘uses genes as medicine’. It repairs faulty or damaged gene copies by transferring a therapeutic or working gene into specific parts of faulty gene copy. This means that gene therapy can be used to replace a faulty gene or to introduce a new gene whose function is to modify the clinical course of a condition or to cure a problem in the gene (Refer to image 2). Image 1 shows how gene therapy is completed using an adenovirus vector while image 2 explains the method of gene therapy and shows how cells are removed, altered and injected back into the patient. Gene therapy has potential to treat and cure many medical conditions such as various types of cancer, degenerative diseases and viral infections such as AIDS. Research into gene therapy still needs to be done before this approach to the treatment of certain conditions will realise its full potential. Trials are being conducted in the United States and Europe and a modest number initiated in other countries, including Australia. The majority of these trials are focussing on treating acquired conditions such as cancer (European Society of Gene & Cell therapy, 2011).
There are two types of genetic technology. Somatic gene therapy is used to repair genes that do not function properly in a person. Not that controversial because it only changes genes in organs and is not passed on to the next generation (p. 116, Garreau, 2005) .
Gene therapy is a provisional technique that is the insertion of normal genes into the cells where there is a missing or miscoded gene to fix a genetic disorder. In the 1960s and early 1970s,
There are two types of cells that can theoretically receive gene therapy. The first is the somatic cell, also called the body cell. This cell's lifetime is only as long as the life span of the individual patient. This is to say that whatever therapy performed on somatic cells is obsolete upon the death of the patient.
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.
