The effect of combining sodium butyrate (NaB), a histone deacetylase inhibitor, and 7-hydroxy-staurosporine (UCN-01) on cytotoxicity in human cervical carcinoma cells was evaluated.HeLa and CaSki cells were treated using NaB alone or in combination with staurosporine (STS) or its analog UCN-01. Cytotoxicity was determined by flow cytometry and morphological assays. Apoptotic pathways were characterized by Western blotting and immunostaining. CaSki cells were also xenografted into nude mice to assess the in vivo effects of NaB/UCN-01 combination.Treatment with NaB and STS or UCN-01 resulted in enhanced apoptosis of cancer cells. Apoptosis involved mitochondrial pathways and overexpression of p53 and p73. In concordance, co-treatment modulated some p53/p73 downstream targets such as p21, BAX, BCL-2 and BCL-X(L), leading to increased caspase-3 and poly(ADP-ribose) polymerase cleavage. In vivo, NaB/UCN-01 combination exerted a substantial tumour growth suppression effect compared with single treatment.UCN-01 was shown to be a potentiator of NaB therapy for cervical cancer cells.
