摘要:
The present invention provides Maternal Sterility Constructs (MSC) and methods of producing sterile progeny lacking germ cells. Female animals carrying the MSC transgene will give rise to a sterile generation, as the MSC specifically eliminates Progenitor Germ Cells (PGCs) of her progeny. These females are called lineage ending females. Male animals carrying the MSC transgene, however, give rise to fertile progeny (assuming the male is not derived from an MSC-transgenic female). Thus, MSC transgenic males can be used to propagate the transgenic line. The invention can be advantageously applied to eliminate pest or invasive species, or to provide effective population control and improve culture performance of farmed species, such as fish and shellfish.

The present invention relates to a method of in vitro isolation of buffalo β-caesin promoter (buCSN2) along with the regions of exon1, intron1 and exon2 from the genomic DNA in vitro (Bubalus bubalis) and its functional activity in using mammary cell line. The novel buffalo β-caesin promoter along with exon1, intron1 and exon2 is isolated and cloned upstream of the Enhanced Green flourescence protein (EGFP) gene and sequenced. The transfection of the DNA construct resulted into production of EGFP protein in mammary cell lines, confirming bioactivity of this newly isolated buffalo promoter sequence. More specifically, the present invention relates to isolation, cloning, sequencing and functional analysis of the buffalo β-casein promoter in vitro using mammary cell line.

A transgenic mouse expressing JSRV Env transgene that is operably linked to a surfactant protein C promoter (SPCp) is disclosed. The transgenic mouse is prone to developing a lung tumor and serves as an animal model for human lung carcinoma.
摘要:
A transgenic non-human animal for overexpressing isoQC, comprising cells containing a DNA transgene encoding human isoQC, characterized in that said human isoQC comprises the amino acid sequence of SEQ ID NO: 1 or an amino acid sequence having at least 75% sequence identity to the amino acid sequence of SEQ ID NO: 1 or a fragment or derivative of the amino acid sequence of SEQ ID NO: 1. Additionally disclosed is a method of screening for biologically active agents that inhibit or promote isoQC.

摘要:
A sensor system for detecting the activation of specific nuclear receptors in a tissue of an animal is provided. The nuclear receptor sensor system comprises a sensor component comprising a nuclear receptor or part thereof coupled to a DNA-binding domain, and a reporter component comprising a reporter gene. Transgenic animals, such as a transgenic pig is provided, which comprises the components of the nuclear receptor sensor system in its genome. Also methods of producing the transgenic animal is provided as well as use of the transgenic animal for evaluating the activity of a nuclear receptor in vivo.

Compositions and methods for treating neuropathies and screening for bioactive agents are also provided herein.
摘要:
The present invention provides for a transgenic non-human animal whose cells contain a DNA sequence comprising: (a) a nerve tissue specific promoter; and (b) a DNA sequence which encodes a receptor for advanced glycation endproducts (RAGE), wherein the promoter and the DNA sequence which encodes the receptor for advanced glycation endproducts (RAGE) are operatively linked to each other and integrated in the genome of the non-human animal, and wherein said non-human animal exhibits a reduced amount of cerebral tissue infarcted following a transient middle cerebral artery occlusion compared to an identical non-human animal lacking said DNA sequence.
