Alternatively, a sample of the cells from the patient is removed and then exposed to the vector within the laboratory setting. This is a radical new technology for correcting genetic defects also known as chimeraplasty. For example, diseases such as cystic fibrosis, combined immune deficiency syndromes, muscular dystrophy, hemophilia, and many cancers result from the presence of defective genes [1]. The defective host gene remains unaltered. Gene Therapy Briefs. Gene therapy works by altering the genetic code to recover the functions of critical proteins. Many traits in individuals are determined phenotypically by an interaction of genetic predisposition with the environment.

Due to the success of the procedure, the patient is now living a healthy life. There is a very narrow line in what is not morally, is no cure, but treatments such as gene therapy may help those who have the disease (Gene Therapy, n.d.). In most dominant disorders the biochemical nature of the abnormality has not been observed. Correction of such chromosomal anomalies is practically not possible by gene therapy as chromosomes typically contain numerous genes. Eventually, it may be predicted that in the distant future gene therapy could be used to produce customized animals with more muscle and milch ability and whatever traits we may desire. One of the first human gene therapy procedures involved injecting the correct ADA gene to a four year old girl with the ADA deficiency. Somatic gene therapy is when blood cells are extracted from a person and a normal gene is then inserted into the defective cell. While gene therapy offers many great benefits to the medical world, there are still some risks involved in receiving the treatment. What are the uses of microbes in medicine?

Today the topic of gene therapy will be discussed, so to begin, what is gene therapy? It would take another decade for optimism about the treatment to resurface. Genetic information is transmitted from one cell to its progeny by duplication or replication of its DNA. Diabetes mellitus in human at younger age is supposedly caused by a special susceptibility of insulin secreting cells to certain viral infections or other environmental exposure. In the distant future, designed viruses or genetic elements may be used to transfer genes to specifically targeted cells in vivo. It has created quite a buzz since its inception as this experimental method leverages healthy genes to cure or deter diseases. The DNA inserts at random and in multiple copies into the cells genome and it is therefore relatively uncontrolled and unpredictable.

Scientists use retroviruses in this form of gene therapy, of which HIV is an example. Although genetic manipulations have occasionally leaded to undesired effects i.e. If experiments involve gene therapy to the patient, then impact over germ line may be a matter of concern. In this case, gene therapy helps to identify and replace defective genes by healthy ones.

Basically, gene therapy is the modification of genes to alter a certain characteristic that ultimately can cure a genetic disease. As such adding healthy versions of the malfunctioning genes tends to be anobviousand elegant mechanism of achieving this. There are some specific concerns of using viruses as a vector to transfer DNA. It is important for the institutional review board to approve every gene therapy research studies before they can be implementedand carried out on patients. This has significant implications, since P53 alterations are the most common genetic abnormalities in human cancers.

For instance, scientists are using it to attempt to cure Parkinsons disease, because only a portion of the brain needs to be targeted. Gene Therapy - Genome.gov Gene therapy of somatic cells will therefore probably prove technically superior to alternative treatments for selected patients with some disorders. Notice that the purpose is not to replace defective genes in the host cell, rather it is to provide a new copy, so the correct protein is expressed, or at least the defective gene is neutralized (Blachford 462). A Summary of Gene Therapy Essay Example | GraduateWay Gene therapy - Mayo Clinic Genetic diseases like sickle-cell anemia are as a result of defective genes.

Although still in development, successful trials have occurred, and conceptually, the idea being tested is ideal in the fight against lethal diseases such as haemophilia, cystic fibrosis and cancer. When deployed inside the body, the doctors may inject the virus that carries the gene directly to the part that has defective cells. Germ line correction would lead to genetic alteration that could be detected in all cells in the body and could be passed on to next generations if the recipient is allowed to reproduce. A new form of medicine with the potential to save and improve millions of live is gene therapy, or gene replacement therapy.

Some of the viruses are normally used as vectors since they tend to deliver new genes by infecting the cells. The very motto of this therapy is to facilitate insertion of piece of DNA in to somatic cell DNA. Gene transfer to somatic cells changes the recipients genome (Hanna, 2006). Gene Therapy Essay Questions: The various domains to be covered for my essay writing. Stuck on your essay?
