BGI Shenzhen
November 15, 2012, Shenzhen, China The availability of a reference genome for a species is extremely important in the deeper understanding of its biology and evolution, and today marks the publication of two studies involving researchers from the BGI on the whole-genome sequencing, analysis and production of high quality reference genomes for the pig in the journals Nature and GigaScience(a BGI and BioMed Central journal). The Nature study from the Swine Genome Sequencing Consortium presents the reference genome of a breed of pig that is an economically important food source, and the GigaScience study, led by researchers from the BGI, Beijing Institute of Animal Science (IAS) and Chinese Academy of Agriculture Science (CAAS), focuses on a miniature pig used for medical research. The Nature study includes the additional genomes of a number of European and Asian wild and domesticated swine species, andalso released today is a series of accompanying articles covering pig genome structure and function, genome annotation, and findings of biomedical relevance in a number of BioMed Central journals.
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.
The study in the international open-access journal GigaScienceannounces 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 Wuzhishan pig 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 identical, allowing greater reproducibility in scientific analyses. 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 also revealed potentially actionable resources including the identification of the porcine counterparts of human drug target genes.
To provide the best understanding of the genetics of the Wuzhishan pig, the researchers atthe BGI in collaboration with scientists from several institutions in China and Denmark,obtained a high quality genome sequence and used this to investigate characteristics that would be of great interest for medical studies. In particular they looked at genes and protein domains that were the pig counterpart of human genes that are important for therapeutic drug activity. These analyses showed that the Wuzhishan pig genome contained a very large number of similar drug target genes for several types of human disorders, indicating that this pig would serve as an excellent model for drug testing in such cases. However, the researchers also found that there were several situations where target genes showed important differences from the human versions. This information is of great use as well, as it provides a clear indication of the types of drug testing for which this organism is not as useful, saving unnecessary experimentation, time and money.
Lead researchers Dr Yutao Du and Prof Shutang Fengnote that, "the physiological similarities to humans was maintained at a genetic level with 84% homology between the two species. While there was a great deal of similarity in genes known to be involved in coronary artery disease and drug target genes, detailed analysis showed that there were several important differences which need to be taken account of."
The scientists also assessed the presence of viruses integrated into the genome, which is a concern given that pigs have been considered as a possible source of xenotransplantation and thus viruses could be transferred to the human patients through transplantation.
Drs Du and Feng noted that the viral analyses provide tools and information for investigating such concerns by allowing more direct assessment of the risk of transmission. They explained that, "both humans and pigs carry viruses hidden within their genomes. One particular virus, porcine endogenous retrovirus (PER), once activated can infect human cells, however the genome sequence has revealed that a specific type PER virus (type C) has been lost from the mini-pig."
Overall, the extensive amount of work in these studies serve as a springboard for more economical and directed means of carrying out biomedical analyses and provide new resources for the investigation of economically important traits, domestication events, and the evolution of this group of animals.
In keeping with the scientific community's goals of making the data underlying the analyses used in published research fully and freely available, all data from the Wuzhishan pig genome are available under a CC0 waiverinthe GigaSciencedatabase, GigaDB, in a citable format, and are also available under the following accession numbers in the NCBI public repositories: NCBI Sequence Read Archive: SRA051254, NCBI BioProject: PRJNA144099, and NCBI GenBankAJKK00000000.The Swine Genome Sequencing Consortium genome and gene annotations are also available from ENSEMBL: http://asia.ensembl.org/Sus_scrofa/Info/Index

Notes to News Writers: 1. GigaScience is co-published by BGI, the world's largest genomics organization, and BioMed Central, the world's largest open-access publisher. The journal covers research that uses or produces 'big data' from the full spectrum of the life sciences. It also serves as a forum for discussing the difficulties of and unique needs for handling large-scale data from all areas of the life sciences. The journal has a completely novel publication format one that integrates manuscript publication with complete data hosting, and analyses tool incorporation. To encourage transparent reporting of scientific research as well as enable future access and analyses, it is a requirement of manuscript submission to GigaScience that all supporting data and source code be made available in the GigaScience database, GigaDB, as well as in their publicly available repositories. GigaScience will provide users access to associated online tools and workflows, and will be integrating a data analysis platform and cloud resources into the database later this year, maximizing the potential utility and re-use of data.

2. BGI was founded in 1999 with the mission of being a premier scientific partner to the global research community. The goal of BGI is to make leading-edge genomic science highly accessible through its investment in infrastructure that leverages the best available technology, economies of scale, and expert bioinformatics resources. BGI, which includes both private non-profit genomic research institutes and sequencing application commercial units, and its affiliates, BGI Americas, headquartered in Cambridge, MA, and BGI Europe, headquartered in Copenhagen, Denmark, have established partnerships and collaborations with leading academic and government research institutions as well as global biotechnology and pharmaceutical companies, supporting a variety of disease, agricultural, environmental, and related applications. BGI has established a proven track record of excellence, delivering results with high efficiency and accuracy for innovative, high-profile research which has generated over 250 publications in top-tier journals such as Nature and Science. These accomplishments include sequencing one percent of the human genome for the International Human Genome Project, contributing 10 percent to the International Human HapMap Project, carrying out research to combat SARS and German deadly E. coli, playing a key role in the Sino-British Chicken Genome Project, and completing the sequence of the rice genome, the silkworm genome, the first Asian diploid genome, the potato genome, and, most recently, have sequenced the human Gut metagenome, and a significant proportion of the genomes for the 1,000 genomes project.
