1Hepatitis B virus-induced oncogenesis显示文摘Hepatocellular carcinoma (HCC) is one of the most com- mon cancers in the world with an annual incidence of more than 500 000 in the year 2000. Its incidence is rising in many countries. Recently, it has been estimated that about 53% of HCC cases in the world are related to hepatitis B virus (HBV). The epidemiological association of HBV with HCC is well established. In recent studies, it was revealed that HBsAg carriers have a 25-37 times increased risk of developing HCC as compared to non-infected people. At present, HBV-associated carcinogenesis can be seen as a multi-factorial process that includes both direct and indirect mechanisms that might act synergistically. The integration of HBV DNA into the host genome occurs at early steps of clonal tumor expansion. The integration has been shown in a number of cases to affect a variety of cancer- related genes and to exert insertional mutagenesis. The permanent liver inflammation, induced by the immune response, resulting in a degeneration and regeneration process confers to the accumulation of critical mutations in the host genome. In addition to this, the regulatory proteins HBx and the PreS2 activators that can be encoded by the integrate exert a tumor promoter-like function resulting in positive selection of cells producing a functional regulatory protein. Gene expression profiling and proteomic techniques may help to characterize the molecular mechanisms driving HBV-associated carcino- genesis, and thus potentially identify new strategies in diagnosis and therapy.Joachim Lupberger Eberhard Hildt 2007World Journal of Gastroenterology2007,13,1:56
2Identification and characterization of a novel bipartite nuclear localization signal in the hepatitis B virus polymerase显示文摘AIM:To characterize the nuclear import of hepatitis B virus(HBV)polymerase(P)and its relevance for the viral life cycle.METHODS:Sequence analysis was performed to predict functional motives within P.Phosphorylation of P was analyzed by in vitro phosphorylation.Phosphorylation site and nuclear localization signal(NLS)were destroyed by site directed mutagenesis.Functionality of the identified NLS was analyzed by confocal fluorescence microscopy and characterizing the karyopherin binding.Relevance of the structural motives for viral life cycle was studied by infection of primary Tupaia hepatocytes with HBV.RESULTS:We identified by sequence alignment and functional experiments a conserved bipartite NLS containing a casein kinaseⅡ(CKⅡ)phosphorylation site located within the terminal protein domain(TP)of the HBV polymerase.Inhibition of CKⅡimpairs the functionality of this NLS and thereby prevents the nuclear import of the polymerase.Binding of the import factor karyopherin-α2 to the polymerase depends on its CKⅡ-mediated phosphorylation of the bipartite NLS.In HBV-infected primary Tupaia hepatocytes CKⅡinhibition in the early phase(post entry phase)of the infection process prevents the establishment of the infection.CONCLUSION:Based on these data it is suggested that during HBV infection the final import of the genome complex into the nucleus is mediated by a novel bipartite NLS localized in the TP domain of HBV polymerase.Joachim Lupberger Stephanie Schaedler Alexander Peiran Eberhard Hildt 2013World Journal of Gastroenterology2013,19,44:8
