[Gene edited animal models applied in human disease research].

Recently, with the development and the continuous improvement of various CRISPR systems represented by CRISPR/Cas9, gene editing technology has been gradually improved, and widely applied to the preparation of animal models of human diseases. The gene edited animal models provide important materials for the study of pathogenesis, pathological process, prevention and treatment of human diseases. At present, the gene edited animal models used in human disease research include mainly the rodent models represented by mice and rats, and large animal models represented by pigs. Among them, rodents differ greatly from humans in all aspects of their bodies and have short life span as well, which cannot provide effective evaluation and long-term tracking for the research and treatment of human diseases. On the other hand, pig is closer to human in physiology, anatomy, nutrition and genetics, which provides an important animal model in the field of organ transplantation and human disease research. In this paper, the application of the gene edited animal models was summarized in the researches of 5 human diseases such as neurodegenerative diseases, familial hypertrophic cardiomyopathy, cancer, immunodeficiency diseases and metabolic diseases. We hope this paper will provide a reference for the research of human diseases and the preparation of relative animal models.
