  • 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: 5861484
    Abstract: The vascula 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: 5806281
    Abstract: A packaged product includes an overwrap material wrapped around the product and overlapped to form a seam bonded to prevent ingress of moisture and a tear tape to tear the overwrap material. The tear tape has a first pressure sensitive layer for bonding to the overwrap and a second layer opposite the first having characteristics such that it acts as a release coat to inhibit bonding of the tear tape to itself and such that it acts to bond the substrate to the overwrap material. The second layer converts by heat from the release coat condition to the bonding condition by being absorbed into the first sub-layer or by including a hard rough surface arranged to inhibit bonding to the first layer which is melted.

  • Patent number: 5401832
    Abstract: Acidic fibroblast growth factor (aFGF) is isolated and purified from human brain tissue. The distinctive and complete amino acid sequences of both bovine and human aFGFs are determined and herein disclosed. Unique genes coding for these disclosed amino acid sequences are constructed. The bovine gene is derived from reverse translation of the aFGF amino acid sequence with unique restriction sites included while the human gene is derived by specific point mutations of the bovine gene. Each gene construct is inserted into an expression vector which is used to transform an appropriate host. The transformed host cells produce recombinant aFGF (r-aFGF), human or bovine, which is purified and has activity equivalent to the native protein. Both recombinant and purified brain-derived human and bovine aFGF are active mitogens for mesoderm and neuroectoderm-derived cells in culture, and promote wound healing of soft tissue, cartilaginous tissue and musculo-skeletal tissue.
