Mechanism of Transfer in Gene Therapy Essay examples -- Gene Therapy
Mechanism of Transfer in Gene TherapyAbstractGene therapy is the guide of frequent genes into the body to re family 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 au naturel(p) DNA. The vector travels to a target cell and inserts the gene, which goes to the host cells nucleus and may integrate into the genome. In cells with dominant negative genes, resulting protein must be prevented from translation or transcription using oligonucleotides or antisense technology. Though many obstacles delay the development of gene therapy, this new field will surely emend the future of medicine.Mechanism of Transfer in Gene TherapyGene therapy is a method of replacing 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 g ene is transferred to the cells nucleus and must be activated in order to function. The gene must be integrated into the cells genome in order for it to continue to function and be replicated. Side effects argon possible because the vector may be detected as a foreign substance by the bodys immune system. Gene therapy may take place either in vivo or in vitro, the transfer may be in either somatic or germline cells, and a pastiche of viral and non-viral vectors may be used.In vivo gene therapy is done inside a living organism. This is accomplished by inhalation, oral administration, intramuscular injection, or intravenous administration (Brooks, 24). Currently, most in vivo experiments have taken place in animals other than humans. Most gen... ...ocated, ensure that gene therapy will be a rotatory aspect of medicines future.
