  • Publication number: 20100150838
    Abstract: Methods are provided for evaluating osteoarthritis (OA), for example for diagnosing OA, to confirm a diagnosis of OA, to assess or prognose progression of OA, determining the severity of a subject who has OA, and determining a subject's risk of developing OA in the future, as are arrays and kits that can be used to practice the methods. In particular examples, the method includes determining an amount of activity (such as an amount of protein present or an amount of expression) of OA risk-related molecules, such as soluble vascular adhesion protein 1 (sVAP-1) or interleukin-15 (IL-15). Also provided are methods of identifying one or more compounds that alter the activity of an OA-related molecule, thereby identifying potential anti-osteoarthritis drugs.

  • Publication number: 20040101510
    Abstract: We measured the levels of 78 different cytokines and growth factors in culture supernatants to determine the cytokine profiles of cells treated with PARC. We found that specific cytokines were suppressed by PARC. PARC can be used to treat diseases such as cancer, autoimmune diseases, rheumatoid arthritis, myeloproliferative disorders, and coronary artery disease, which are characterized by too much mitosis.

  • Publication number: 20040009503
    Abstract: Human extracellular ribonucleases (RNases) are widely distributed in various organs and body fluids and together with other members of the mammalian RNase A superfamily. In addition to their RNase activity, several RNases have been shown to have special biological actions, i.e., antitumor, antiviral and angiogenic properties. However, the molecular mechanisms of such activities are unclear. Using protein microarrays amplified rolling circle amplification (RCA), we investigated the effects of EDN (Rnase 2), ECP (Rnase 3) and RNase 1 on leukocytes cytokine production. We measured the levels of 78 different cytokines and growth factors in culture supernatants to determine the cytokine profiles of cells treated with different combinations of RNases and RNase inhibitors.

  • Patent number: 5443964
    Abstract: The invention comprises a plasmid vector, utilizing genetic material that causes high levels of expression of poxvirus genes, and the method of using this genetic material. One preferred embodiment comprises an upstream cis-acting element of a poxvirus gene encoding the major protein component of the poxvirus A-type inclusion. A second preferred embodiment of the invention comprises a downstream cis-acting element of a poxvirus gene encoding the major protein component of the poxvirus A-type inclusion. These elements are inserted upstream and downstream respectively, of selected cloned genes in the plasmid vector to obtain very high levels of expression of the cloned gene.
