knockout mouse(Noun) Any of several forms of mice that have been genetically engineered by inactivating specific genes. Knockout mouse. A knockout mouse is a genetically engineered mouse in which researchers have inactivated, or knocked out, an existing gene by replacing it or disrupting it with an artificial piece of DNA.
The gene knockout is created by selectively disabling a specific target gene in a particular type of cells called embryonic stem cells. The three scientists received the Lasker Award in 2001 for this achievement. The technique has been used to make several thousand different knockout mice.Knockout mice have become one of the most useful scientific tools in helping to understand the human genome and its roles in disease. The process of gene targeting involves two processes.lthough knockout mice are extremely useful in studying gene function, producing custom knockout mice is very expensive. Typical cost ranges anywhere from $3,000 to as much as $30,000.
