  • Publication number: 20230104136
    Abstract: Provided are methods, assays, and kits for detecting hepatocellular carcinoma, as well as methods for stratifying subjects among higher and lower risk categories for having hepatocellular carcinoma, and methods of treating and managing treatment of subjects that are suspected or at risk of having hepatocellular carcinoma. Although previous work has attempted to address the need for a highly sensitive, early predictor of hepatocellular carcinoma by assessment of one or more biological factors, none have approached the degree of sensitivity that is required for clinically relevant determination of whether a subject, especially a non-symptomatic subject, has that condition. The present inventors have discovered that certain combinations of factors fulfill this need by conferring a high level of accuracy that was not previously attainable.

  • Publication number: 20210041458
    Abstract: The present invention provides methods, compositions, apparatus, and kits for assessing glycoforms of proteins as a biomarker for disease. A purified recombinant form of lectin is used as a detector molecule to specifically label target sugars expressed in disease states. The high affinity of recombinant lectin allows for automation of assays that would be used in the diagnosis of diseases such as, but not limited to, cancer or liver disease.

  • Patent number: 10143720
    Abstract: The present invention provides small molecule inhibitors of hepatitis B virus (HBV) covalently closed circular (ccc) DNA, which are useful as therapeutics in the management of chronic HBV. The compounds of the invention achieve epigenetic modification of the cccDNA, histone modification and histone deacetylase activity inhibition, thus modulating HBV cccDNA. The present invention further provides methods for modulating HBV cccDNA, for treating or preventing HBV in a subject, and for modulating cccDNA transcription of hepatitis B in a subject.
