Abstract

Chronic myelogenous leukemia (CML) is associated with the high TK activity chimeric protein BCR-ABL, known to contribute to cell tumorogenicity, resistance to apoptosis and differentiation. STI571, the TK inhibitor, is the current treatment for CML. One possible approach to overcome STI571 resistance appearing in some cases, involves the combination of histone deacetylase inhibitors (HDI) and STI571. We demonstrated that in K562, the CML cell line, pivaloyloxymethyl butyrate (Pivanex)-induced apoptosis, differentiation and reduced BCR-ABL protein levels and that the combination of Pivanex with STI571 acted synergistically. These data suggest the possible benefit of combining this HDI with STI571 for treatment of CML.
