Sodium butyrate and panobinostat induce apoptosis of chronic myeloid leukemia cells via multiple pathways

Purpose Histone deacetylase inhibitor (HDACI) is a novel therapeutic option for cancer. However, the effects of HDACIs on chronic myeloid leukemia (CML) and the underlying mechanisms are still unknown. The aim of this study was to investigate the effect and the mechanism‐of‐action of two HDACI members, sodium butyrate (NaBu) and panobinostat (LBH589) in K562 and the adriamycin–resistant cell line K562/ADR.
