摘要:
The present disclosure relates methods and compositions useful for prevention of porcine reproductive and respiratory syndrome virus (PRRSv) in animals, including animals of the species Sus scrofa. The present teachings relate to swine wherein at least one allele of a CD163 gene has been inactivated, and to specific methods and nucleic acid sequences used in gene editing to inactivate the CD163 gene. Swine wherein both alleles of the CD163 gene are inactivated are resistant to porcine reproductive and respiratory syndrome virus (PRRSv). Elite lines comprising homozygous CD163 edited genes retain their superior properties
摘要:
Non-human animals and offspring thereof comprising at least one modified chromosomal sequence in a gene encoding a CD163 protein are provided. Animal cells that contain such modified chromosomal sequences are also provided. The animals and cells have increased resistance to pathogens, including porcine reproductive and respiratory syndrome virus (PRRSV). The animals and offspring have chromosomal modifications of a CD163 gene. The invention further relates to methods of breeding to create pathogen-resistant animals and populations of animals made using such methods.
摘要:
The present invention provides transgenic, large non-human animal models of Ataxia-Telangiectasia, as well as methods of using such animal models in the identification and characterization of therapies for Ataxia-Telangiectasia.
摘要:
The present invention refers to a method for the transfer of DNA sequences or exogenous genes into animal sperm cells by means of the use of episomal vectors. The invention also relates to the use of “Sperm Mediated Gene Transfer” (SMGT) technology for the creation of genetically modified individuals.
摘要:
A genetically modified livestock animal comprising a genome that comprises inactivation of a neuroendocrine gene selective for sexual maturation, with the inactivation of the gene preventing the animal from becoming sexually mature. Methods of using, and processes of making, the animals are taught.
摘要:
The invention provides double knockout transgenic pigs (GT/CMAH-KO pigs) lacking expression of any functional αGAL and CMAH. Double knockout GT/CMAH-KO transgenic organs, tissues and cells are also provided. Methods of making and using the GT/CMAH-KO pigs and tissue are also provided.
摘要:
The present invention relates to a genetically modified pig as a model for studying atherosclerosis. The modified pig model displays one or more phenotypes associated with atherosclerosis. Disclosed is also a modified pig comprising a mutation in the endogenous ApoE gene or part thereof, LDL gene or part thereof, LDL receptor gene, or transcriptional or translational product or part thereof. The invention further relates to methods for producing the modified pig; and methods for evaluating the effect of a therapeutical treatment of atherosclerosis; methods for screening the efficacy of a pharmaceutical composition; and a method for treatment of a human being suffering from atherosclerosis are disclosed.
摘要:
The present invention relates to a genetically modified pig as a model for studying psoriasis. The modified pig model displays one or more phenotypes associated with psoriasis. Disclosed is also a modified pig comprising a mutation in the endogenous ILK-I Ra, JunB/cJun, CD18, IKK2, and/or LIG1 gene, and/or a human, porcine and/or murine PPARs, PPAR-δ, lκB-α, STAT3c, Integrin beta 1, Integrin alpha 2, MEK1, Amphiregulin, BMP-6, VEGF, JunBΔec-JunΔep, IL-I a, TGF.beta 1, CD18 hypo, Cre/lkk2FL/FL, Dsg1, SCCE, TGF-a, TNF-a, IL-20, IFN-g, LIG1 KO, KGF, IL-6, PAFR1 Cre/lkk2FL/FL, IL1 R, Dsg3, IFN-gamma, p40, ILI Ra, IKK2, JunB/c-Jun, and/or LIG1 gene, transcriptional and/or translational product or part thereof. The invention further relates to methods for producing the modified pig; and methods for evaluating the effect of a therapeutical treatment of psoriasis, for screening the efficacy of a pharmaceutical composition, and a method for treatment of human being suffering from psoriasis are disclosed.
摘要:
Provided is a method for the production of transgenic animals, especially pigs, by the use of nuclear transfer from genetically modified or other embryonic stem cells to either enucleated oocytes which were matured in vivo or in vitro and activated or to enucleated zygotes.
摘要:
Methods and cell lines for cloning ungulate embryos and offspring, in particular bovines and porcines, are provided. The resultant fetuses, embryos or offspring are especially useful for the expression of desired heterologous DNAs, and may be used as a source of cells or tissue for transplantation therapy for the treatment of diseases such as Parkinson's disease.
