Patents by Inventor Stuart A. Aaronson

Stuart A. Aaronson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6225088
    Abstract: The present invention relates to a potent mitogenic growth factor called plasminogen-like growth factor (PLGF) isolated from conditioned medium of human lung fibroblasts. The protein has an apparent molecular weight under reducing conditioning of 87 kDa and is structurally related to hepatocyte growth factor (HGF); however unlike HGF, which appears to be specific for hepatic cells, PLGF stimulates a wide spectrum of target cells including melanocytes, endothelial cells and epithelial cells but excludes fibroblast cells. The present invention further relates to recombinant cloned DNA fragments and expression cell systems expressing biologically active PLGF. The availability of purified PLGF as well as immunological and molecular probes should facilitate the study of proliferative disorders in which the factor plays an important role.

  • Patent number: 5985553
    Abstract: The isolation, cloning and characterization of a human gene related to but distinct from the EGF receptor gene has been described. Nucleotide sequence of the gene and amino acid sequence of the polypeptide encoded by the gene have been determined. The use of the nucleic acid probes and antibodies having specific binding affinity with said polypeptide for diagnostic and therapeutic purposes has also been described.

  • Patent number: 5965359
    Abstract: Discoveries are disclosed that show particular aspects of recombinant DNA technology can be used successfully to produce a hitherto unknown type of human Platelet-Derived Growth Factor (PDGF) receptor protein free of other PDGF receptors. These proteins can be produced from DNA segments in cells in various functional forms. These forms variously enable biochemical and functional studies of these novel receptors as well as production of antibodies. Means are described for determining the level of expression of genes for specific types of PDGF receptor proteins, for example, by measuring mRNA in cells with PDGF receptor type-specific DNA probes or by measuring antigen in biological samples with type-specific antibodies.

  • Patent number: 5916755
    Abstract: A DNA fragment distinct from the epidermal growth factor receptor (EGFR) and erbB-2 genes was detected by reduced stringency hybridization of v-erbB to normal genomic human DNA. cDNA cloning revealed a predicted 148 kd transmembrane polypeptide with structural features identifying it as a member of the erbB family, prompting designation of the new gene as erbB-3. It was shown to be expressed as a 6.2 kb transcript in a variety of normal tissues of epithelial origin. Markedly elevated erbB-3 mRNA levels were demonstrated in certain human mammary tumor cell lines. These findings indicate that increased erbB-3 expression, as in the case of EGFR and erbB-2, plays a role in some human malignancies. Using erbB-3 specific antibodies (polyclonal or monoclonal), the erbB-3 protein was identified as a 180 kDa glycoprotein, gp180.sup.erbB-3. The intrinsic catalytic function of gp180.sup.erbB-3 was uncovered by its ability to autophosphorylate in vitro.

  • Patent number: 5863739
    Abstract: Potent neutralizing monoclonal antibodies to the human .alpha. PDGF receptor (.alpha. PDGFR) and fragments thereof are described. These monoclonal antibodies specifically bind to an epitope on .alpha. PDGFR, inhibits PDGF binding with PDGF, antagonizes PDGF, and does not bind .beta. PDGFR receptor. A hybridoma cell line producing such a monoclonal antibody, methods of in vivo imaging of a pathological conditions and methods of inhibiting the growth of a neoplasia expressing .alpha. PDGFR, which use these monoclonal antibodies are also described. In vitro assays for detecting the presence of .alpha. PDGFR and for evaluating the binding affinity of a test compound are also described.

  • Patent number: 5792638
    Abstract: The oncogene of the present invention, isolated by expression cloning from a human ovarian cancer is a mutant of TC21. The present invention teaches that ras-related genes not thought to have transforming potential can contribute importantly to cancers which have been refractory to oncogene detection. The present invention teaches that another ras relative gene, R-ras, which was previously reported to lack transforming potential, has transforming capacity as well. Thus, these and other genes similarly related to prototype and activated by analogous mechanisms may be important in the diagnosis and prognosis of certain cancers, as well as be critical in the design of rational approaches to therapy of cancers in which they play a role.

  • Patent number: 5595895
    Abstract: A highly efficient genetic cloning system is disclosed which is particularly useful for cloning cDNA copies of eukaryotic mRNAs and can direct the orientation of inserts in .lambda.-plasmid composite vectors with large cloning capacities. Cleavage of such vector DNA, by the restriction enzyme SfiI, for example, creates two different non-symmetrical 3' extensions at the ends of vector DNA. Using a linker-primer and an adaptor, cDNA is prepared to have two different sticky ends which can be ligated to those of the vector. When the cDNA fragments and the vector DNAs are mixed, both the molecules can assemble without self-circularization due to base-pairing specificity. This system provides (1) high cloning efficiency (10.sup.7 -10.sup.8 clones/.mu.g poly(A).sup.
