How are knockout mice used
There are several thousand different strains of knockout mice. Many mouse models are named after the gene that has been inactivated. For example, the p53 knockout mouse is named after the p53 gene which codes for a protein that normally suppresses the growth of tumours by arresting cell division and/or inducing apoptosis. Humans born with mutations that deactivate the p53 gen… WebNucleases can also be used to engineer knockout mice. ZFN, TALEN, and CRISPR/Cas9 systems can all be targeted to specific regions of the genome, and induce non-homologous repair at the site of DNA damage. These nucleases are microinjected into a zygote, which is then implanted into a female mouse for gestation.
