The laboratory mouse is the most widely used experimental model for genetic studies and preclinical drug development in cancer. The Mouse Genome Editing Unit is dedicated to the genetic edition of the mouse germ line and to the generation of genetically modified mouse strains. Hundreds of these strains have been created at our Unit. In many cases, they contain modifications that reproduce the genetic alterations found in human cancer and are introduced in the mouse to generate preclinical models of the disease, thereby contributing to the development of more efficient targeted therapies. Genetically modified mice are also created for testing in vivo, in a physiological context, hypothesis related to the molecular mechanisms that convert a normal cell to a malignant cell or that contribute to tumour expansion and invasion of distant organs, ultimately causing death. Cancer is an extremely complex disease that cannot be sufficiently well studied in vitro in a tissue culture plate. The generation of genetically modified mice is one of the basic pillars that sustain cancer research at the CNIO.
