  • Patent number: 8697050
    Abstract: The onset ratios and pathological conditions of collagen-induced arthritis and adjuvant arthritis in model mice and rats, respectively, were successfully ameliorated by topically expressing the cyclin-dependent kinase inhibitors p161NK4a and p21Cip1 in articular tissues using adenoviral vectors. In the synovial cells of CDKI-transduced mice, expression of inflammatory cytokines was inhibited. Described are the use of the p21Cip1 protein for inhibiting abnormal proliferation of synovial tissues, inflammation in synovial tissues and/or expression of inflammatory cytokines in synovial tissues; the p21Cip1 gene; compounds promoting the activity or expression of the p21Cip1 protein; and pharmaceutical compositions containing these molecules. Also provided are method of screening for compounds participating in the abnormal proliferation of synovial tissues, inflammation in synovial tissues and/or the expression of inflammatory cytokines in synovial tissues targeting the p21Clip1 protein.

  • Publication number: 20080226599
    Abstract: The onset ratios and pathological conditions of collagen-induced arthritis and adjuvant arthritis in model mice and rats, respectively, were successfully ameliorated by topically expressing the cyclin-dependent kinase inhibitors p16INK4a and p21Cip1 p in articular tissues using adenoviral vectors. In the synovial cells of CDKI-transduced mice, expression of inflammatory cytokines was inhibited. Described are the use of the p21Cip1 protein for inhibiting abnormal proliferation of synovial tissues, inflammation in synovial tissues and/or expression of inflammatory cytokines in synovial tissues; the p21Cip1 gene; compounds promoting the activity or expression of the p21Cip1 protein; and pharmaceutical compositions containing these molecules.

  • Patent number: 5747251
    Abstract: Combinations of polymerization, non-competitive hybridization and assay techniques is disclosed. In one aspect of the method, one member of a regular or anchored primer pair is modified to include a coupling agent capable of forming a tight bond (resistant to uncoupling in an alkaline denaturing environment) with a reactant. Competitive PCR is performed and the PCR products are coupled via the coupling agent to a reactant on the surface of a solid phase support. The bond between the reactant and the solid phase support in this and all embodiments is also resistant to uncoupling in an alkaline denaturing environment. In another aspect of the method, a primer is tightly coupled to the bound reactant and a polymerization of the competitor and target nucleic acids is performed on the solid phase. A third embodiment uses at least three primers, one of which is internal to the PCR templates and is bound to the solid phase support on which the entire PCR takes place.
