  • Patent number: 7071159
    Abstract: The vascular endothelial cell growth factor (VEGF) inhibitors of the present invention are naturally occurring or recombinantly engineered soluble forms with or without a C-terminal transmembrane region of the receptor for VEGF, a very selective growth factor for endothelial cells. The soluble forms of the receptors will bind the growth factor with high affinity but do not result in signal transduction. These soluble forms of the receptor bind VEGF and inhibit its function.

  • Patent number: 6639123
    Abstract: Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding the melcanocortin-3 receptor protein (MC-3R). MC-3R deficient transgenic animals have increased fatmass and reduced lean body mass, showing that the MC-3R protein is involved in the regulation of body fat and muscle mass. These MC-3R deficient transgenic animals can be used to select for and test potential modulators of MC-3R. This data allows for methods of screening for MC-3R modulators which effect body weight and associated methods of treating various disorders associated with inappropriate regulation of body weight. The disclosure also relates to a MC-3R/MC-4R double knockout mouse which can be used to select for and test potential modulators (e.g., agonists or antagonists) of MC-3R and/or MC-4R. It is shown that MC-3R serves a non-redundant role, when compared to MC-4R, in the regulation of energy homeostasis.

  • Patent number: 6375929
    Abstract: The present invention relates to methods of gene therapy for inhibiting angiogenesis associated with solid tumor growth, tumor metastasis, inflammation, psoriasis, rheumatoid arthritis, hemangiomas, diabetic retinopathy, angiofibromas, and macular degeneration Gene therapy methodology is disclosed for inhibition of primary tumor growth and metastasis by gene transfer of a nucleotide sequence encoding a soluble form of a VEGF tyrosine kinase receptor to a mammalian host. The transferred nucleotide sequence transcribes mRNA and a soluble receptor protein which binds to VEGF in extracellular regions adjacent to the primary tumor and vascular endothelial cells. Formation of a sVEGF-R/VEGF complex will prevent binding of VEGF to the KDR and FLT-1 tyrosine kinase receptors, antagonizing transduction of the normal intracellular signals associated with vascular endothelial cell-induced tumor angiogenesis.

  • Patent number: 6197553
    Abstract: A process is disclosed for the large scale isolation and purification of plasmid DNA from large scale microbial fermentations. The process exploits a rapid heating method to induce cell lysis and precipitate genomic DNA, proteins and other debris while keeping the plasmid in solution. Suspending the microbial cells in buffer and then heating the suspension to about 70-100° C. in a flow-through heat exchanger results in excellent lysis. Continuous flow or batch-wise centrifugation of the lysate effects a pellet that contains the cell debris, protein and most of the genomic DNA while the plasmid remains in the supernatant. This invention offers a number of advantages including higher product recovery than by chemical lyses, inactivation of Dnases, operational simplicity and scaleability.
