Gene Therapy 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 success, then it stops the gene from causing any further damages and restores the cell to its normal functioning self. Gene therapy was first introduced as a part of human trials in 1990. The idea behind gene therapy is to correct dysfunctional genes and make the patient’s life easier and more livable. Gene therapy begins with locating the dysfunctional gene. The most complicated part of gene therapy is the transportation of a new gene into another. The new gene data is most commonly inserted into an adeno-associated virus, which is a vector, this virus disallows the potential harm that might be within the body because it does not have the necessary genes to spread an illness in the human body and there are no known causes of this virus infecting humans. The virus, or vector, infects only the targeted cell. There are certain requirements for something to be considered a vector before it is used. A vector must be able to Target the right cells, next step would be Integrate the gene in the cells, th... ... middle of paper ... ...r a better alternative, to those who are hoping their offspring have better and healthier lives, gene therapy can make that happen. Diseases such as hemophilia, muscular dystrophy, cystic fibrosis, Gauscher’s disease, cardiovascular diseases, cancers, and more can be made into a rarity. People are unsure of gene therapy because of how new it is, they berate gene therapy, but for some people, gene therapy may be their only chance to live.

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 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...
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 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...
Every year, the rate of mortality increasing because most diseases may lead to death if not treated early. One of the methods that can be used to cure some diseases is by using the treatment known as gene therapy. Based on Pruitt’s (2008) study, numbers of inherited and acquired diseases were reduced since gene therapy has the ability to provide new treatments to cure them. According to Shi and Zou (2008), gene therapy is defined as expression of protein or interrupts the synthesis of protein in cell by transferring the genetic material into a host in order to treat or prevent a disease. Besides that, Kelly (2007) stated that an “abnormal” hereditary disease-causing gene in an individual’s cells and tissues is treated and used gene therapy by to replace them with a “normal” gene. Around 1970’s, idea to use “genes” as “drugs” for human therapy was originally from United States (Giacca, 2010). Moreover, there are some objectives in using the gene therapy as a treatment. First, gene therapy is used to cure or slow the progression of disease by introducing the genetic material into target cells and next objective is to aim at the direct correction of endogenous genetic defects by delivered some additional copies of a gene (Pruitt, 2008; Giacca, 2010). Furthermore, Yadav and Tyagi (2008) found that there are two types of gene therapy which are germline gene therapy and somatic cell therapy. As stated by Shi and Zou (2008), therapy that involved modification of any cells in a patient’s body is called as somatic cell gene therapy while germ line gene therapy is therapy that involved modifying of human eggs or sperms that pass genes on to future generations. Other than that, animal tissue culture is used to test the effective...
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).
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,
This book is important in informing the audience on the currently position of gene therapy especially to experts who are trying to ensure that gene therapy becomes successful. Being successful involves it being
Gene therapies necessity, stems from the fact that it can cure, life threatening gene based diseases, with minimal after effects. Although there are some ethical and physical issues that can occur through this technology, when comparing it to the other genetic technologies, it’s quite reliable. Although it is in its infancy, the technology has still been present for several years, with the first case of gene therapy being done in 1990. Sure, there have been some complications, but its still a growing technology with a strong future in front of
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
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.
There are many kinds of treatments and therapies for certain diseases and disorders. For example, cancer patients might receive chemotherapy, radiation therapy, and surgery. Although these treatments may work or help some patients, there is another option that is evolving. Research and experimental testing have helped scientists discover a new way of treating and possibly curing various diseases and disorders such as influenza, HIV, hepatitis, heart disease, diabetes, and cancer.Gene Therapy was first discovered in the middle of the 1980’s and was successful in it’s very first trial. Gene Therapy could possibly become the major treatment or even the cure among many diseases and disorders in the near future. Scientists and researchers are working
