Zusammenfassung
Background: We previously showed that panobinostat, a novel pan-deacetylase inhibitor, has a potent apoptotic activity in vitro and induces growth delay of HCC xenografts in nude mice. Panobinostat is able to induce cell death in HepG2 (p53wt) and in Hep3B (p53null) cell lines that is not dependent on canonical apoptotic pathways. Here we analyse the effect on ER-stress by panobinostat treatment. Methods: HepG2 and Hep3B cells were cultured under standard conditions and treated for 48h with 0.1µM panobinostat. Sub-G1 events were quantified by flow cytometry after propidium iodide staining and verified by immunof…
