  • Publication number: 20210215714
    Abstract: Provided herein are methods for using determinative urinary biomarkers for identifying a human subject suffering from an alternative pathway (AP)-associated nephropathy. Also provided herein is a method for using determinative urinary biomarkers to determine whether a human subject suffering from a complement mediated nephropathy is likely to respond to an inhibitor of the alternative complement pathway (“AP”) in treating the complement mediated nephropathy. Further provided herein is a method for using urinary biomarkers to assess the therapeutic response of a human subject suffering from an AP-associated nephropathy receiving inhibitors of the complement alternative pathway (AP inhibitors).

  • Patent number: 7985541
    Abstract: Methods for detecting populations of newly synthesized and newly initiated RNAs in a cell-free system are described. Suitable templates for the populations of newly synthesized and newly initiated RNAs are viral replicon RNAs, particularly HCV viral replicon RNA. The newly synthesized and newly initiated RNAs may be formed in the presence of a labeled nucleotide analog suitable for detection and/or quantitation of the RNAs. The assay may be employed to identify small molecule inhibitors of RNA synthesis of positive strand RNA viruses such as Hepatitis C Virus.

  • Publication number: 20100093018
    Abstract: Cells expressing chimeric hepatitis C virus NS4A protein are disclosed, as are vectors and methods for preparing such cells and methods of using the cells and the chimeric proteins therein in screening assays for detecting compounds that alter the associative characteristics of NS4A proteins. Disclosed screening assays are suitable for use in high throughput screening of compound libraries to identify compounds with a exhibiting specific anti-viral activity against hepatitis C virus.

  • Patent number: 7101676
    Abstract: The present invention relates to methods of identifying a molecule from a library of molecules that inhibits binding of human immunodeficiency virus nucleocapsid 7 polypeptide (NCp7) to an oligonucleotide which comprises admixing an NCp7 polypeptide with at one labeled HIV-1 psi-site oligonucleotide and an amount of the molecule to be tested under binding conditions; and determining the amount of oligonucleotide bound to the NCp7 polypeptide, wherein a decrease in the amount of oligonucleotide bound in the presence of the molecule compared with the amount of oligonucleotide bound in the absence of the molecule indicates that the molecule inhibits binding of NCp7 polypeptide to the oligonucleotide.
