Mini-pig tale provides massive amount of genomic data for human health
Date:11/14/2012

November 15, 2012, Hong Kong, China The international open-access journal GigaScience (a BGI and BioMed Central journal) announces the publication of the whole-genome sequencing and analysis of the Wuzhishan Pig, an extensively inbred, miniature pig, which can serve as an excellent model for human medical research. The availability of the mini-pig genome provides a wealth of genetic tools that will enable detailed and well thought-out analyses on an animal that shares a substantial number of complex diseases with humans. The work here, led by researchers from the BGI, Beijing Institute of Animal Science (IAS), and Chinese Academy of Agriculture Science (CAAS), also revealed potentially actionable resources including the identification of the porcine counterparts of human drug target genes.

Pigs are one of the oldest domesticated livestock species, and as well as providing one of the largest sources of meat worldwide, also provide important medical industrial resources, such as pharmaceutical-grade heparin and heart valves for xenotransplantation. The pig shares many of the same complex genetic diseases as humans, making them excellent models for studying the underlying biology of human disease. Furthermore, the similarity of the pig diet and digestive system with humans makes them ideal for investigation of metabolic diseases and nutritional analyses. The Wuzhishan pig used in this study provides additional advantages for medical analysis: its small size makes it easy to handle; and its long history of inbreeding have resulted in a breed of pigs made up of individuals that are genetically very similar, allowing greater reproducibility in scientific analyses.

To provide the best understanding of the genetics of the Wuzhishan pig and tools for laboratory studies, the researchers at the BGI in collaboration with scientists from several institutions in China and Denmark, carried out whole genome sequencing. They obtained a genome sequenc
