  • Patent number: 10054600
    Abstract: Diagnostic biomarker panel, method, kit, and device for diagnosing the severity and/or prognosis of cirrhosis are provided. More specifically, the invention provides a novel biomarker panel correlating to HVPG and esophageal varices. The invention further provides a biomarker panel and non-invasive test methods that predict non-clinically significant portal hypertension HVPG and non-clinically significant esophageal varices when the expression of the biomarker panel correlates with HVPG of less than 12 mmHg. The invention further provides that the patients with the expression of the biomarker panel correlating to non-clinically significant HVPG and esophageal varices can be excluded from undergoing esophagogastroduodenoscopy (EGD) screening and those correlating to HVPG equal to or greater than 12 mmHg are indicated for EGD.

  • Patent number: 8129349
    Abstract: The present invention relates generally to the treatment and prevention of diseases characterized by excess cell proliferation and/or activation. In particular, the present invention provides compositions and methods to suppress the activation and/or proliferation of various cells. In some preferred embodiments, the present invention provides compositions and methods to suppress the activation and/or proliferation of mesenchymally derived cells (including, but not limited to hepatic stellate cells), as well as cells with abnormal growth characteristics. In some particularly preferred embodiments, the present invention provides compositions and methods to inhibit or eliminate fibrosis. In alternative preferred embodiments, the present invention provides compositions and methods to induce fibrosis. In still further embodiments, the present invention provides methods and compositions to treat and/or prevent cancer.
