Indolocarbazoles have been identified as novel inhibitors of protein kinase C (PKC), with Gö 6976 as one of its most potent and selective representatives. Recombinant PKC isozymes alpha, beta 1, delta, epsilon, and zeta were used in in vitro kinase assays to investigate Gö 6976 with respect to isozyme-specific PKC inhibition. Gö 6850, identical with GF(More)
Fas is a type-I membrane protein that transduces an apoptotic signal. Binding of Fas ligand or agonistic anti-Fas antibody to Fas kills the cells by apoptosis. Studies in the nematode Caenorhabditis elegans have suggested that proteases such as interleukin-1 beta-converting enzyme (ICE) or the product of the C. elegans cell-death gene ced-3 are involved in(More)

Multimerization of GAAANN generates sequences frequent in virus-inducible promoters. We distinguished different types of (GAAANN)4 sequences mediating virus inducibility. Type I (NN = GT, GC, CT, or CC) responds to IFNs and to IRF-1 and causes silencing. Type II (NN = TG) and type III (NN = CG) neither silence nor respond to IRF-1 or IFN. Type III mediates(More)
BACKGROUND HIPK2 (homeodomain-interacting protein kinase 2) has been identified as a nuclear serine/threonine kinase. A central function of HIPK2 is repressing transcription of homeodomain containing transcription factors. RESULTS AND CONCLUSIONS We show here that HIPK2 activates transcription mediated by tumor suppressor p53 responsive promoter elements.(More)
The normalization of data obtained from hybridization experiments with DNA chips to determine mRNA expression and concentration (gene expression profiling) is an unsolved problem. Furthermore, slight changes in mRNA expression or small numbers of mRNA molecules which may be relevant to disease cannot be detected so far. We have designed a method to(More)
The rapid development of new diagnostic procedures, the mapping of the human genome, progress in mapping genetic polymorphisms, and recent advances in nucleic acid- and protein chip technologies are driving the development of personalized therapies. This breakthrough in medicine is expected to be achieved largely due to the implementation of(More)
Platelel-derived growth factor and phorbol ester cause an increase in vascular endothelial growth factor (VEGF) mRNA expression in control NIH 3T3 fibroblasts and NIH 3T3 fibroblasts overexpressing human protein kinase C (PKC) a. In the case of phorbol ester-induced VEGF expression, the VEGF mRNA levels were significantly higher in cells overexpressing(More)
Under the Adverse Drug Reactions Information Scheme (ADRIS) data and knowledge relevant to the etiology of adverse drug reactions (ADRs) such as chemical structure of parent compounds, metabolites, covalent adducts, nucleic acid and protein sequences, protein structures, pharmaco-, toxico- and enzyme kinetics, pharmaco- and toxicodynamics, protein(More)
