A Study On Gene Therapy Essay

Gene therapy is a very controversial topic that has been discussed in the last five years and is being heavily studied to help cure cancer. Gene therapy is a technique aimed at treating genetic disorders by introducing the correct form of the defective gene into the patient’s genome (Dunlop et al., 2010).

Fifty years after the idea of gene therapy was first proposed, gene therapy has become a possible treatment for a couple different diseases. Before this treatment was approved, some serious unfavorable effects were found in clinical trials. However, these effects fueled more basic research in order to improve, in efficiency and safety. Gene therapy has been used for patients with blindness, neuromuscular disease, hemophilia, immunodeficiencies, and cancer.

Just in case you are a little shaky on the topic of gene therapy I will briefly explain. Gene therapy is a type of treatment used

Whether gene therapy should be allowed to be used in practice is currently a very controversial topic. In my opinion, I do not think that it should be allowed. Gene therapy is a technique where genetic material is inserted into a patient to replace missing or defective genes. Gene therapy can be further broken down into two categories: somatic and germline. From there, somatic gene therapy can be approached in two ways: in-vivo and ex-vivo. For the process of gene therapy to begin, the proper vector needs to be acquired. Once a vector is chosen, the vector delivers the new gene into the target cell. Then, the target cell becomes infected with the vector. Next, the vector’s genetic material is inserted into the target cell. Then finally, functional

Li, and Huang discuss the controversial topic of gene therapy by first providing a factual summary of gene therapy. Their introduction goes into the specifics of the types of vectors (carriers that deliver a gene to target cells) used to transfer genes in order to aide damaged proteins. Afterwards, they transition into the detailed of process of gene therapy. They start this off with naked DNA and state it is the simplest approach to nonviral transfers and the least toxic method. However, despite being the least toxic and a nonviral transfer it does not have as great of an effect as Cationic lipids. Cationic lipids have been used in various experiments but are known to be safe only when administered in small doses. Furthermore they go into

Gene therapy is an experimental form of treatment, where normal genes are placed into missing or defective ones in order to correct or alter genetic disorders. In other terms, it is the therapeutic delivery of nucleic acid polymers into a patient 's cells as a drug to treat disease (Gennady, 2015). After many attempts at modifying human DNA by nuclear gene transfer as well as insertion of human DNA in the nuclear genome, the first successful gene therapy was in 1990 where it was used to cure four-year-old Ashanti DaSilva who had Severe Combined Immune Deficiency (IDF 2013 National Conference). Since then gene therapy has been used to cure and treat serious diseases such as Chronic Granulomatus Disorder, Hemophilia, and a wide variety of Cancers, and other genetic and acquired diseases (American Society of GENE & CELL THERAPHY, online).

Gene therapy is a relatively new technology that has shown some promising results. Such as the drug called Strimvelis that is used to help children with severe combined immunodeficiency, a disease that leaves infants with little to no protection against viruses, bacteria, fungi, and other potentially harmful things. It appears to be a cure carried out through a genetic pair. Strimvelis was tested on 18 children, starting 15 years ago, all of whom are still alive today. Gene therapy is used to inject genes into a person’s cells and tissues in order to treat a disease, as well as hereditary diseases where an abnormal allele is replaced with a fully functional allele. The carrier, called a vector, is used to transport the normal gene to the target cells. The most common type of vector are viruses that have been genetically altered to carry human DNA. Scientists have been trying to control the way the viruses have evolved encapsulating and delivering their genes to normal cells in a pathogenic way by manipulating the viral genome to remove disease-causing genes and inserting healthy ones. Theoretically, it is possible to transform either the cells of the body (somatic) or the cells of the sperm, ova, and their precursors (germline). All of the gene therapy experiments so far on humans have been directed to somatic cells, because germline experiments have been remaining controversial. Somatic gene therapy is split into two broad categories: ex vivo (cells are modified outside of the body then returned back again) or in vivo (genes are changed in cells while still located inside of the

With our current society rapidly advancing in both the technological and medicinal world, many new treatments have been born that can be used to treat genetic conditions that regular antibiotics and surgeries simply have no positive or progressive effect. Gene therapy is when a newly developed gene is transferred, or introduced, to an already existing gene, it is the attempt to treat one’s genetic disorder at the molecular level and could significantly improve the human population and provides hope to people with disabilities. Gene therapy goes straight to the source and alleviates symptoms of the disorder. The gene receiving this new development is in some shape or form, mutated, or defective. If the gene therapy is a

Gene therapy is a rapidly developing technology first used in 1990.1 It involves the use of modified DNA inserted into an organism with a missing or mutated sequence. There are two methods of delivering this correction into the patient’s cells. In the viral method, a virus containing the vector with the corrected form of the gene, infects the cell naturally. Adenoviruses, adeno-associated viruses, lentiviruses, and retroviruses can all be used. They each utilize a different method of delivery and form of DNA. Adeno-associated viruses and lentiviruses are the easiest forms to construct.2 The corrected DNA faces many obstacles to gene expression and ultimately protein production. The viruses must target and enter the correct cell, avoid

Gene Therapy is an experimental form of treatment that aims to get rid of genetic conditions at their source. It also may be used to replace a faulty gene with a working version or introduce a new gene to cure a condition or modify its effects. ( Victoria State Government, 2011) It is designed to introduce genetic material into cells to compensate for abnormal genes or to create a beneficial protein within the gene. If a mutated or incomplete gene creates a protein needed that is faulty or not present, gene therapy has the ability to introduce a copy of that specific gene to restore the function of the protein within that gene.

Genetic disorders have plagued people for ages. However, recent research and new discoveries in gene therapy has brought new hope to those unfortunate individuals that are ailed by their own genetics. Gene therapy is a technique of correcting defective gene sequences specifically responsible for the disease. In 1990, the first successful clinical trial of gene therapy was initiated for adenosine deaminase deficiency (GT). Since then, the number of clinical treatments induced worldwide has increased exponentially. Gene therapies have been a part of modern medicine for almost two decades now. Only recently have scientists started to deliver on their immense promise after a string of setbacks raised doubts about the safety of manipulating human DNA. The idea of gene therapy has been around for a while, but it wasn’t until recently that this field of molecular biology has come more into the light with its advancements over time. Experimentation has been an ongoing process with gene therapy. Although, ethical issues of controversy have surrounded this topic since the beginning. But new facts on gene therapy continues to rebuttal most controversy.

There are three techniques that researchers are working on. The first and most common is ex vivo ( or "outside the living body") therapy. The defective cells are removed from the patient and replaced with the normal DNA before returning to the body. This therapy targets the blood cells because many genetic defects alter the functioning of one type of these cells or another. But since blood cells have limited life spans follow-up treatments are required. Future efforts will most likely target stem cells of the bone marrow. Stem cells are ideal for gene therapy because they appear to be immortal. Researchers have obtained stem cells from human bone marrow, but they are having difficulties getting genes into the cell as well as inducing the cells to produce many new blood cells (Anderson, 1995).

Every living thing is the product of the genes that were passed down from ancestors. Genes make up everything we are. One gets their traits from their parents. Most people live full lives with relatively good health. However, some people inherit mutated genes or faulty genes. This could lead to genetic disorders that could be life threatening. Even today, many genetic disorders still remain incurable, leaving many people without hope. Genetic therapy could be their answer. It is through this research that the cure for genetic disorders can be found. Though some people believe it is unethical or immoral to alter genes, current therapeutics have not been able to save the lives of the patients with these diseases. Genetic therapy
