Pigs are ideal organ donors for xenotransplantation and an excellent model for studying human diseases, such as neurodegenerative disease. Transcription activator-like effector nucleases (TALENs) are used widely for gene targeting in various model animals. Here, we developed a strategy using TALENs to target the GGTA1, Parkin and DJ-1 genes in the porcine(More)
Pig shows multiple superior characteristics in anatomy, physiology, and genome that have made this species to be more suitable models for human diseases, especially for neurodegenerative diseases, because they have similar cerebral convolutions compared with human neocortex. Recently, CRISPR/Cas9 system shows enormous potential for engineering the pig(More)
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease with complex genetic inheritance. Genome-wide association studies have identified SLE susceptibility variations at the IRF7/KIAA1542 locus and with STAT4 gene in European populations. We decided to investigate the association of single-nucleotide polymorphisms (SNPs) in the IRF7/KIAA1542(More)
Accumulating evidence suggests that faulty epigenetic reprogramming leads to the abnormal development of cloned embryos and results in the low success rates observed in all mammals produced through somatic cell nuclear transfer (SCNT). The aberrant methylation status of H3K9me and H3K9me2 has been reported in cloned mouse embryos. To explore the role of(More)
Genetic engineering in livestock was greatly enhanced by the emergence of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9), which can be programmed with a single-guide RNA (sgRNA) to generate site-specific DNA breaks. However, the uncertainties caused by wide variations in sgRNA activity impede the utility of(More)
Pigs lack functional uncoupling protein 1 (UCP1) making them susceptible to cold. Nevertheless, several pig breeds are known to be cold resistant. The molecular mechanism(s) enabling such adaptation are currently unknown. Here, we show that this resistance is not dependent on shivering, but rather depends on UCP3 and white adipose tissue (WAT) browning. In(More)
Uncoupling protein 1 (UCP1) is localized on the inner mitochondrial membrane and generates heat by uncoupling ATP synthesis from proton transit across the inner membrane. UCP1 is a key element of nonshivering thermogenesis and is most likely important in the regulation of body adiposity. Pigs (Artiodactyl family Suidae) lack a functional UCP1 gene,(More)
OBJECTIVES Systemic lupus erythematosus (SLE) is the most common systemic autoimmune disease which likely involves complex interactions between genes and the environment. Two large-scale genome-wide association studies (GWAS) have implicated many loci as genetic risk factors associated with primary Sjögren's syndrome (pSS). Among them there are a number of(More)
N-ethyl-N-nitrosourea (ENU) mutagenesis is a powerful tool to generate mutants on a large scale efficiently, and to discover genes with novel functions at the whole-genome level in Caenorhabditis elegans, flies, zebrafish and mice, but it has never been tried in large model animals. We describe a successful systematic three-generation ENU mutagenesis(More)
