Cancer and 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.
It was in the 1980’s that scientist began looking at alternative ways of treatments, one is gene therapy. Scientist would insert human genes into a bacteria cell. Then the bacteria cell would transcribe and translate the information into a protein. Once that is done the scientist would then introduce the protein into human cells. Gene therapy can be simply viewed as inserting bits of foreign DNA into a patient’s tissue in hope...

... fight the disease. It is crucial that regulation be a necessary component of gene therapy research and applications. In hopes that the government can regulate and can receive this treatment, not restricting it to people that has serious genetic diseases. Gene therapy will change the field of medicine from what it is today. As scientist discovers more genes and their functions, the potential of this treatment is limitless. Though gene therapy is an auspicious treatment choice for numerous diseases (including inherited disorders, some types of cancer, and certain viral infections), the procedure remains precarious and is still under study to make sure that it will be safe and effective. Thus government regulators and scientist must take a lead role in adopting a practical approach to address these issues and determining the correct procedures for dealing with them.
