[Application of genetically engineered mice model in the research of gastrointestinal tumor].
The gene knockout is based on the DNA homologous recombination and embryonic stem cell technology. It is an experimental method for modification of specific gene loci, which is one of the most direct means to clarifying gene functions. The similarity of genomes between mouse and human is as high as up to 95%. The life cycle of mice is relatively short, and easy to breed with stronger reproductive capacity. Therefore, the knockout mice are suitable for observing the whole process of disease pathogenesis. With genetic manipulation technology, researchers can produce the simulations of phenotypic effect by human genetic variation. This article focuses on genetically engineered mice models and their application in gastrointestinal cancer.
