Causes And Treatments Of Gene Therapy

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).

DNA has about 12 million single nucleotide polymorphisms and thousands of copy number variants, most of which are not harmful. Sometimes these mutations in genes can cause genetic disorders that end up altering or inhibiting protein function. Gene Therapy focuses on correcting the mutated genes usually by inserting a normal gene into the genome. Researchers treat these diseases this way by repairing dysfunctional gene or by providing copies of the missing gene. They isolate the normal DNA and package it into a vector. Other ways include replacing the abnormal gene with a normal one, repair the mutated gene, or altering the regulation of a certain gene. As of right now, reparative results have been marginal, there is potential of gene therapy treating single-gene disorders.

Gene therapy provides many benefits to the patients who undergo it. Biotechnologists believe that a genetic disease can be removed with this treatment. For example, on the U.S. National Library of Medicine website, it states, “Researchers are testing several approaches to gene therapy, including: Replacing a mutated gene that causes disease with a healthy copy of the gene. Inactivating, or ‘knocking out,’ a mutated gene that

Some people may wonder what gene therapy is. Gene therapy is the replacing of defective or missing genes with normal genes in order to cure the disorder. In the future, this technique may be used to prevent or treat a disorder by inserting

Gene therapy is the insertion of normal or genetically altered genes into cells to replace defective genes. The gene is usually inserted into

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.

Gene therapy is a method involving DNA to treat or prevent disease. It is the insertion of a corrected gene into an organism’s cell to mask the presence of the dysfunctional gene, instead of surgery or using drugs. Put simple, gene therapy is the process of using DNA as a drug. Generally, a vector (‘delivery vehicle’) is used to go to the cells where it is needed and deliver a gene, if this is successful, the cell will then be able to produce a functional protein to treat or prevent the disease. Since the gene causing CF was discovered, it is now possible to attempt gene therapy to

Gene therapy is an experimental treatment, which is used to replace mutated, improperly functioning genes with regular DNA. There are several gene therapy methods, most of which involve using a vector to transport the corrected gene into targeted cells. Retro viruses, adeno viruses, adeno ascosciated viruses and liposomes are commonly used as vectors. Naked DNA (DNA without

Gene therapy is an experimental medical procedure that uses the genes in our bodies to either treat or prevent disease by introducing new genetic material into human cells (ie. cancer cells) to create the necessary proteins that allows the cell become healthy (SOURCE). Gene therapy can also be used as an alternative to other medical disorders rather than having a surgical procedure done or using drugs such as chemotherapy. For example, Joseph Panno, research

According to Kenneth Pakenham, Jo McEntire, and Jessica Williams (2013), in “Making Connections” Gene therapy and genetic tests are long experiment by scientists to find out specific genes are related to fatal diseases and birth defects. Many severe diseases depend on the gene type. When genes are known genetic tests for many genes will be available. Despite several challenges for gene therapy, genes treatment is possible identifying their defective genes tests.

With the development and improvement of gene therapy, further applications have been discovered and attempted. In particular, gene

The first method is to attach the gene to a virus. This is done by removing the functional group of the virus that harms the body and attaching the gene that is to be delivered into the cell. Retroviruses and adenoviruses are the two types of viruses used in gene therapy. Retroviral vectors are used because it inserts its own DNA into the host’s DNA. There are two ways to use retroviral vectors in gene therapy, introduce the vector intravenously, or removing the patient’s tissue, inserting the vector in a lab setting, then replacing the tissue. One of the flaws using the retroviral vector method in gene therapy is that integrase enzyme(responsible for integrating the retroviral DNA into the host cell) can insert the gene in any position in the genome. If the gene is place in the middle of another functional sequence, it would cause a malfunction of that particular gene. Not all gene sequences have a significant function, but there is still considerable risk in the retroviral vector method. Although it can be dangerous, this is most commonly used in patients with a small chance of survival, so the risk is not as
