Generation of LEPR Knockout Rabbits with CRISPR/CAS9 System.
The LEPR gene encodes a leptin hormone receptor, and its mutations are associated with morbid obesity, dysregulation of lipid metabolism, and fertility defects in humans. Spontaneous Lepr mutations have been described in rodents, and Lepr knockout animals have been generated, in particular, using the CRISPR/Cas9 system. Lipid metabolism in rodents significantly differs from that in humans or rabbits, and rabbits are therefore considered as the most relevant model of morbid obesity and lipid metabolism dysregulation in humans. LEPR knockout rabbits have not been reported so far. In this work a LEPR knockout rabbit was generated by introducing a deletion of the region around LEPR exon 10 using the CRISPR/Cas9 system. The body weight of the knockout rabbit was significantly higher than the average body weight of the wild type rabbits. CRISPR/Cas9-mediated generation of LEPR knockout rabbits will allow the development of a model of morbid obesity and endocrine defects due to leptin receptor mutations in humans.
期刊介绍：
Doklady Biological Sciences is a journal that publishes new research in biological sciences of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
