From Wikipedia, the free encyclopedia. A gene knockout (abbreviation: KO) is a genetic technique in which one of an organism 's genes is made inoperative (knocked out of the organism). knockout mouse (left) that is a model of obesity, compared with a normal mouse. A conditional knockout allows gene deletion in a tissue or time specific manner. This is done by introducing short sequences called loxP sites around the gene.
A new gene is injected into an adenovirus vector, which is used to introduce the modified DNA into a human cell. If the treatment is successful, the new gene will make a functional protein. Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein.If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.A gene that is inserted directly into a cell usually does not function.f a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
