20100199360 | ENHANCER-CONTAINING GENE TRAP VECTORS FOR RANDOM AND TARGETED GENE TRAPPING - The present invention relates to a novel class of gene trap vector (enhanced gene trap vectors, eGTV) for efficiently identifying silent or weakly expressed target genes in mammalian genomes, methods of their production and methods for identifying and mutating target genes by using the enhanced gene trap vectors. The gene trap vectors of the present invention can also be used for inducing the expression of silent genes and enhancing the expression of weakly expressed genes. The use of the enhanced gene trap vectors for creating transgenic organisms to identify gene function and to validate pharmaceutical compounds prior to clinical applications is a further aspect of the present invention. | 08-05-2010 |
20100132055 | ANIMAL MODEL FOR THE SELECTION AND VALIDATION OF AGENTS ACTIVE AGAINST PULMONARY EMPHYSEMA AND COLORECTAL CANCER - The present invention relates to a non-human animal model, cell and tissue cultures derived therefrom, which do not produce or produce only suboptimal levels of one or more functional sestrins and in addition do not produce or do only produce suboptimal levels of latent transforming growth factor β binding protein 4 (ltbp4). Furthermore, the present invention relates to a method for selecting agents for treating the pulmonary emphysema and/or the colorectal cancer exhibited by utilizing the animal model, cell or tissue culture of the invention. The animal model, cell or tissue culture is suitable for preclinical testing of efficacy, toxicity and bioavailability of potential agents. | 05-27-2010 |
20090113561 | GENE TRAP CASSETTES FOR RANDOM AND TARGETED CONDITIONAL GENE INACTIVATION - A new type of gene trap cassette, which can induce conditional mutations, relies on directional site-specific recombination systems, which can repair and re-induce gene trap mutations when activated in succession. After the gene trap cassettes are inserted into the genome of the target organism, mutations can be activated at a particular time and place in somatic cells. The gene trap cassettes also create multipurpose alleles amendable to a wide range of post-insertional modifications. Such gene trap cassettes can be used to mutationally inactivate all cellular genes temporally and/or spatially. Cells which contain the inventive gene trap cassette can be used for identification and/or isolation of genes and for the creation of transgenic organisms to study gene function at various developmental stages, including the adult, as well as for the creation of animal models of human disease useful for in vivo drug target validation. | 04-30-2009 |
