The usage of genes as medicine give rise to the concept of 'Gene Therapy'. In the process of Gene therapy, a defective gene copy is repaired by transmitting therapeutic gene copy into those cells of an individual. So thereby, a faulty gene could be replaced or a medical condition may be corrected by introducing a new gene. Gene therapy has a promising future as it is powerful enough to treat many genetic conditions and also other deathly disease like AIDS, cancer etc.
Though the potential of "gene therapy" is realized and recognized, it remains still on an experimental level and needs to worked on before accepting as the best solution. Gene therapy was put into practical use for treating immune deficiency disease called "adenosine deaminase" ADA deficiency in 1990s. This is when the gene transmittal of "corrective genes" into stem cells happened for the first time in practice.
The task of making gene therapy to work yielding positive results is substantial. In order to put it to practical use, firstly we must understand well the defect in question and locate the faulty genes in the system. In addition to that, the identified defectives genes should be accessible, the appropriate healthy gene set or curative gene set should be made available and lastly a way to transmit this gene to that defective area must be clearly constructed. The final part is the most challenging procedure in the process of gene therapy. "Gene Delivery" denotes how to make the curative gene reach the defective area. Few of these vectors would assist us in the problem of 'gene delivery'.

A favorable method for "gene transfer" would be using harmless viruses as carriers of genes into cells. This method is not...

...s, designed personalities, master races, or Frankenstein monsters will be created can be given no credence in the light of what is presently known. The best insurance against possible abuse is well-informed public. With proper safeguards offered by the scientific society, this powerful therapeutic procedure would provide great benefits reducing the sufferings and death caused by genetic disorders

- In April 2000 two babies were born with severe combined immunodeficiency disorder, which causes them to live inside protective “sterile” bubbles. Seeing this French researches removed stem cells from the infants’ marrows and put in genetically altered viruses. Two years later, the children are still healthy (Trefil). Gene therapy is where a single defective gene is replaced with a good one to treat a disease. Adding genes that cause the right proteins to be made is also the use of gene therapy. There are two types of gene therapies: somatic and germ-line.... [tags: Gene Therapy, Somatic, Germ Line]

- Mechanism of Transfer in Gene Therapy Abstract: Gene therapy is the transfer of “normal” genes into the body to replace defective or undesired genes. The transfer may be in somatic or germline cells and may take place in vivo or in vitro. The DNA may be inserted in a retrovirus, adenovirus, adeno-associated virus, herpes simplex virus, or liposome, or it may be naked DNA. The vector travels to a target cell and inserts the gene, which goes to the host cell’s nucleus and may integrate into the genome.... [tags: Gene Therapy]

- Gene Therapy is Revolutionizing Medicine "We used to think that our fate was in our stars, but now we know that, in large measure, our fate is in our genes, "quotes James Watson. This fate that Watson is talking about is contained in our genes, and deals with a new technique, gene therapy. Gene therapy is revolutionizing the world of medicine. Many physicians are predicting that in twenty years gene therapy may change the practice of medicine from a treatment-based to a prevention-based practice.... [tags: Biology Health Essays]

- Due to the fact that the field of biotechnology is very serious and potentially dangerous, rules must be set down in order to keep the research in check. The high risk research of genetic therapy needs guidelines that have to be followed in order to keep the study just. The articles that are discussed in this essay focus on ethical issues and ideas that should be followed in the field in order to keep research safe and valid. In an article titled “The Ethical Implications of Gene Therapy” the group of advisers on Ethical Implications of Biotechnology of the European commission states issues and rules that should be abided by, along with beliefs on the direction of biotechnology....

- Ten years ago researchers from the U.S., Britain, France, Germany, Japan and China sat down and began developing the most important map ever made. Instead of roads and landmarks, this was a map of letters. It was “a rough map of the 3 billion letters of genetic instructions that make us who [we] are” (“First”). On Monday, 26 June 2000, the researchers announced that the map of the human genome was complete. On 26 June 2000 the news of the completion of the human genome was on all the major news wires, televisions and newspapers.... [tags: Gene Therapy Essays]

- What is Gene Therapy and what is it used for. Gene therapy (otherwise known as somatic gene therapy or therapeutic gene therapy) is a process that is used to correct defective genes responsible for development of various diseases. (www.accessexcellence.org/RC/AB/BA/Gene_Therapy_Overview.php) There are two main types of gene therapy; somatic (body) cell gene therapy and germ line gene therapy. As it suggests, somatic gene therapy is correcting the faulty genes of normal body cells. Germ line therapy is altering genes in gametes.... [tags: Medical, Genetics, Medicine, DNA]

- Nanotechnology and Medicine The active pursuit of knowledge in nanotechnology could revolutionize the treatment and detection of various diseases in the future. Nanotechnology is the branch of science that focuses on the development of technology at the molecular scale, including the development of instruments that have been applied to many fields, such as the automotive, cosmetic, and fabric industries. In medicine, nanotechnology has already been applied to the treatment of diabetes, the production of prosthetic limbs, and the improvement of life for the paralyzed, and many believe it is also the key to curing cancer and even immortality....

- Gene Therapy: the Danger of Enhancement I. Introduction Gene therapy has the potential to revolutionize modern medicine. The techniques of gene therapy are still in their infancy as medical treatments and there are still many problems which must be solved before gene therapy will live up to its potential. However, it is very likely that gene therapy will become a reality at some point in the future and when that time comes, the ethical questions surrounding gene therapy will be pushed to the forefront of medicine....

- Often, television will portray the future as people relying on robots and machinery to do the work and tell them what needs to be done and when. As farfetched as it may have sounded years ago, this type of technology is taking its steps into the real world. The future of medicine is being rushed in by a wave of new technology. A whole new type of therapeutics will be on the market. Among these advances health care and insurance could be drastically affected. These are the topics described in the following articles....

- Priotities of Gene Therapy Gene therapy is a relatively new area of medicine that attempts to apply recent advances in molecular biology, genetics and biotechnology to the treatment of human diseases. Gene therapy uses a set of approaches to the treatment of human disease based on the transfer of genetic material (DNA) into an individual. Gene delivery can be achieved either by direct administration of gene-containing viruses or DNA to blood or tissues, or indirectly through the introduction of cells manipulated in the laboratory to harbor foreign DNA....
