A knockout mouse (left) that is a model for obesity, compared with a normal mouse. There are several thousand different strains of knockout mice. [3] Many mouse models are named after the gene that has been inactivated.
A conditional gene knockout allows gene deletion in a tissue in a tissue specific manner. This is required in place of a gene knockout if the null mutation would lead to embryonic death, [13] or a specific tissue or cell type is of specific interest. This is done by introducing short sequences called loxP sites around the gene.
Most strains of nude mice are slightly "leaky" and do have a few T cells, especially as they age. In addition, knockout mice with more complete defects in the immune system have been constructed (e.g. RAG1 and RAG2 knockout mice). For these reasons, nude mice are less popular in research today.
Gene knock-in originated as a slight modification of the original knockout technique developed by Martin Evans, Oliver Smithies, and Mario Capecchi.Traditionally, knock-in techniques have relied on homologous recombination to drive targeted gene replacement, although other methods using a transposon-mediated system to insert the target gene have been developed. [3]
[2] [3] Many of the targeted alleles are designed so that they can generate both complete and conditional gene knockout mice. [3] [4] The IKMC was initiated on March 15, 2007, at a meeting in Brussels. By 2011, Nature reported that approximately 17,000 different genes have already been disabled by the consortium, "leaving only around 3,000 more ...
The International Mouse Phenotyping Consortium (IMPC) is an international scientific endeavour to create and characterize the phenotype of 20,000 knockout mouse strains. [1] [2] [3] Launched in September 2011, [1] the consortium consists of over 15 research institutes across four continents with funding provided by the NIH, European national governments and the partner institutions.
In 1990, the gene knockout technique was just developing. There was a lack of information on the initial events that occur throughout the development of the vertebrate embryo . In order to form a better understanding, the instructions for making an entire set of DNA in a person or organism need be dissected, and the genes involved with this ...
