  • Publication number: 20160202274
    Abstract: The inventors have proposed a novel panel of human plasma protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Plasma from patients with hepatic cirrhosis induced by infection with the hepatitis C virus (HCV) were analysed. Several proteins associated with liver scarring and potentially also related to viral infection were identified. These proteins include 14-3-3 protein zeta/delta, adiponectin, afamin, alpha-1-antitrypsin, alpha-2-HS-glycoprotein, apolipoprotein C-III, apolipoprotein E, C4b-binding protein beta chain, intact/cleaved complement C3dg, corticosteroid-binding globulin, fibrinogen gamma chain, beta haptoglobin at pH 5.46-5.

  • Publication number: 20160077109
    Abstract: The inventors have proposed a novel panel of human serum protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Serum from patients with varying degrees of hepatic scarring induced by infection with the hepatitis C virus (HCV) was analysed. Several proteins associated with liver scarring and/or viral infection were identified. These proteins include the inter-?-trypsin inhibitor heavy chain H4 fragments, complement factor H-related protein 1, CD5L, Apo L1, and ?2GPI. Increased and decreased thiolester cleavage of a2M and Complement C3, respectively, was also detected. The concentrations of these novel biomarkers can be determined using an immunoassay where the concentrations would reflect the extent of fibrosis. A fibrosis scoring scale for each of the novel biomarkers is proposed.

  • Patent number: 8957106
    Abstract: A proliferation of cells can be reduced by contacting the cells with a compound having formula (I) where R and R? are each alkyl groups, R? is hydrogen or an alkyl group and X3, X4 and X5 are each independently selected from the group consisting of hydrogen, benzyl, t-butyldimethylsiloxy radical and triphenylmethyl. Accordingly, compounds of formula (I) can be used for treatment of tumors including melanoma. Also a secretion of a matrix metalloproteinase (MMP) enzyme by cells can be reduced by contacting the cells with the compound having formula (I). Accordingly, compounds of formula (I) can be used for treatment physiological conditions associated with an elevated MMP level, such as tumors.
