Gene Therapy - Essay ExampleGene therapy uses a vector which functions to carry through DNA inside body cells after packaging. The DNA, once in the body through the vector goes into the bloodstream then into cells and finally is incorporated into a chromosome. However, sensitive DNA approaches have been considered too more so in the field of vaccine development. Once embedded in the patients system, the DNA is denotative by the cell machinery, leading to the production of therapeutic protein which corrects the patients condition. Emphasis lies on administering a gene that will cause a protein to be expressed and that the patient specifically needs. In addition, with the advances in knowledge of nuclease functions in humans, there have begun explorations into ways of incorporating genes that encode nucleases into chromosomes. The expressed nucleases then disrupt the genes make the disease by editing the chromosome (Giacca, 2010).The concept of gene therapy was first thought possib le in 1972 but caution was implored especially concerning its application/ experimentation on humans. In 1990, however, Ashanti DeSilva became the first recipient of gene therapy treatment in the United States for ADA-SCID. Early skepticisms arose with several initial clinical failures with umteen regarding gene therapy as an over-rated part but successes since 2006 have seen many regain their faith in this new form of treatment. Over 2,000 recorded clinical trials have so far been performed on humans. These include successful treatment of diseases such as multiple myeloma, Parkinsons disease, Lebers congenital amaurosis, adrenoleukodystrophy, hemophilia, ADA-SCID, chronic lymphocytic leukemia and acute lymphocytic leukemia. With such successes, many governments and companies (especially research institutions) have continued to invest even more on gene therapy. Recently, Glybera became the first gene therapy procedure to be embraced in Europe and the
