Abstract: A method to increase the efficiency of transduction of hematopoietic and other cells by retroviruses includes infecting the cells in the presence of fibronectin or fibronectin fragments. The fibronectin and fibronectin fragments significantly enhance retroviral-mediated gene transfer into the cells, particularly hematopoietic cells including committed progenitors and primitive hematopoietic stem cells. The invention also provides improved methods for somatic gene therapy capitalizing on enhanced gene transfer, hematopoietic cellular populations, and novel constructs for enhancing retroviral-mediated DNA transfer into cells and their use.
Abstract: A method is described for the rapid identification and isolation of cells based on the presence or absence of an ectopically-expressed N-acetyllactosaminide 3-? Galactosyltransferase (?GT) enzyme for the production of ?Galactosyl-(1,3)Galactosyl (?Gal) epitopes on the surface of ?Gal-negative cells. These cells which are genetically modified to express the ?GT enzyme and ?Gal epitopes on glycosylated lipids and proteins of the cell surface are then labeled via an antibody composition which recognizes and binds the ?Gal epitopes on the cell surface. Cells labeled with the anti-?Gal antibody can be isolated by sorting via fluorescence activated cell sorting (FACS), or by magnetic panning techniques. This method is suitable for the rapid positive or negative selection of ?Gal-positive cells from within a population of ?Gal-negative cells without the need to expose cells to antibiotics for any period of time.

Abstract: The present invention is directed to isolated nucleic acid molecules that encode LIM mineralization protein, or LMP. The invention further provides vectors comprising splice variants of nucleotide sequences that encode LMP, as well as host cells comprising those vectors. Moreover, the present invention relates to methods of inducing bone formation by transfecting osteogenic precursor cells with an isolated nucleic acid molecule comprising a nucleotide sequence encoding splice variants of LIM mineralization protein. The transfection may occur ex vivo or in vivo by direct injection of virus or naked plasmid DNA. In a particular embodiment, the invention provides a method of fusing a spine by transfecting osteogenic precursor cells with an isolated nucleic acid molecule having a nucleotide sequence encoding LIM mineralization protein, admixing the transfected osteogenic precursor cells with a matrix and contacting the matrix with the spine.
Abstract: The invention relates to methods and products for deregulating gene transcription in neurodegenerative disease associated with an expanded polyglutamine tract in mutant proteins.

Abstract: The present invention relates to methods of inducing neuronal production in the brain, recruiting neurons to the brain, and treating a neurodegenerative condition by providing a nucleic acid construct encoding a neurotrophic factor, and injecting the nucleic acid construct intraventricularly into a subject's brain.
Abstract: Disclosed is a developmental animal model of temporal lobe epilepsy and other seizure-related disorders. In particular, the invention provides a method of inducing a permanent change in the neurological development of a rodent, such as a rat, comprising daily administration of low doses of a kainate receptor agonist to the animal in the second postnatal week, wherein after treatment with the kainate receptor agonist the animal exhibits reproducible seizure-like symptoms when exposed to mild to moderate stressors. Rats treated using the above method are particularly useful as a non-human system for studying temporal lobe epilepsy, as well as for studying the efficacy of potential anti-epileptic compounds and pharmaceutical preparations.

Abstract: Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. Methods of generating mutations in genes of interest and of making various cells mismatch repair defective through the use of chemicals to block mismatch repair in in vivo are disclosed.

Abstract: The invention relates to novel degradation resistant FGF-1, and methods for producing and using the same. More specifically, the invention relates to identification of a thrombin degradation resistant FGF-1, an a nucleic acid encoding the same. The thrombin degradation resistant FGF-1 can elicit responses that are otherwise typically impeded by degradation of FGF-1 by thrombin. Thrombin degradation resistant FGF-1 is an important molecule for effecting an FGF-1 response that would be otherwise inhibited by thrombin. Thus, the present invention provides a powerful therapeutic for diseases or disorders wherein an FGF-1 response can mediate a reduction in the frequency or intensity of a symptom of the disease or disorder but for degradation of FGF-1 before it can effect the response.
