Abstract | INTRODUCTION: The development of novel antithrombotic agents directly affecting gene expression requires well established, reliable and useful in vitro model systems for initial validation of drug effects. Since most proteins involved in coagulation are synthesized by the liver, the hepatoblastoma cell line Hep G2 is introduced, here, as a model system to test nucleic acid based coagulation inhibitors. METHODS: Hep G2 cells were characterized with respect to prothrombin, tissue factor and factor VIII expression in dependence of cell culture conditions. Reliable enzyme linked immuno sorbent assays as well as viability tests were introduced that allow drug screening procedures with multiple probes in microplate format. Furthermore, a multiplex PCR-procedure has been presented that offers the possibility to simultaneously detect the effects of a selected compound on two coagulation proteins in comparison to a house keeping gene. RESULTS: DISCUSSION:
Nucleic acid based agents require cellular in vitro model systems since they affect the process of gene expression and not the gene product. Hep G2 cells are a useful model to study effects of novel nucleic acid based coagulation inhibitors with an antisense mechanism of action on protein and mRNA level.
