Problems solved by technology

Traditional gene knockout and tissue-specific knockout mediated by Cre / LoxP or Red recombination system have played an important role in this area as an effective research tool, but deletion of important genes related to embryonic development often results in small Mouse embryos are malformed or die early in the embryo so that adult animals cannot be obtained

Abstract

A process for preparing the transgenic mouse able to specifically express Cre recombinant enzyme in cental nerve system includes such steps as using the terminals' regulatory sequence of 1.8 kb GFAP gene to configure the transgenic carrier pGFAP-Cre-hGH containing two beta-glubolin insulators, GFAP5' terminal regulatory region, Cre recombinant enzyme gene and human growth hormone gene, injecting the 7.6 kbtransgenic fragment beta globin insulator-pGFAP-Cre-hGH into mouse's fertilizer eggs, transplating them in the deference duct of male mouse, and developing to obtain the target mouses.

Description

technical field [0001] The present invention relates to the 1.8kb 5' end regulatory region of glial cell acidic protein (glial fibrillary acidic protein, GFAP) gene cloned from 129sv mouse genome library by PCR screening method and using the regulatory sequence to prepare central A method for preparing transgenic mice specifically expressing Cre recombinase in the nervous system. Background technique [0002] The central nervous system, including the brain and spinal cord, is the high-level center of various functional activities of human beings and the material basis of human thought and consciousness activities. In 1989, the United States took the lead in launching a nationwide brain science plan focused on protecting the brain and preventing brain diseases, and named the last decade of this century the "Decade of the Brain". This move was immediately responded by the International Brain Research Organization and many international academic organizations. Therefore, the ...
