Advanced hepatocellular carcinoma still represents an unmet medical need that has only a limited overall survival despite the introduction of the multi-kinase inhibitor sorafenib. Recently, inhibitors of histone and other protein deacetylases have been established as novel therapeutic approaches to cancer diseases. We here review the molecular rationale for(More)
Inhibition of deacetylases represents a new treatment option for human cancer diseases. We applied the novel and potent pan-deacetylase inhibitor panobinostat (LBH589) to human hepatocellular carcinoma models and investigated by which pathways tumor cell survival is influenced. HepG2 (p53wt) and Hep3B (p53null) responded to panobinostat treatment with a(More)
We investigated the effect of AEE788, a novel dual receptor tyrosine kinase inhibitor of the EGF and the VEGF receptor, for treatment of human HCC cell lines and in a subcutaneous xenograft model. Cell viability and apoptosis of HepG2 and Hep3B cells incubated with 0.1-100 microM AEE788 were quantified. In vivo, HepG2 cells were xenografted to NMRI mice and(More)
BACKGROUND The endocannabinoid system is involved in many inflammatory diseases, such as Crohn's disease (CD) and ulcerative colitis (UC). The distribution and expression of cannabinoid receptors 1 (CNR1) and 2 (CNR2) in combination with inflammatory cytokines and RAGE (receptor of advanced glycation end products), which is also overactive in these(More)
The cannabinoid system (CS) is implicated in the regulation of hepatic fibrosis, steatosis and inflammation, with cannabinoid receptors 1 and 2 (CB1 and CB2) being involved in regulation of pro- and antifibrogenic effects. Daily cannabis smoking is an independent risk factor for the progression of fibrosis in chronic hepatitis C and a mediator of(More)
Post-translational modifications of chromatin components are significantly involved in the regulation of tumor suppressor gene and oncogene expression. Connective tissue growth factor (CTGF) is an epigenetically regulated growth factor with functions in angiogenesis and cell-matrix interactions and plays a pivotal role in hepatocellular carcinoma (HCC). The(More)
Tumor cells have the capability to trans- and to dedifferentiate, for example by reactivating embryonic development genes and stem cell characteristics. The aim of our study was to show the differential expression of stem- and progenitor cell markers in human hepatocellular carcinoma cell lines (HCC). Different human HCC cell lines (HUH7, HUH7 5-15, HUH7(More)
