The aim of the study was to investigate the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on histone deacetylase-mediated proliferation inhibition. In the colon cancer cell line HT29 butyrate-mediated proliferation inhibition was enhanced by the additional presence of indomethacin (IM) and/or nordihydroguaiaretic acid (NDGA). Sensitisation to butyrate-mediated proliferation inhibition was abolished by the general caspase inhibitor Z-VAD-fmk, however, only IM-induced cell detachment was prevented by the caspase inhibitor but not that induced by NDGA or NDGA plus IM. In contrast to the parental cell line HT29, in the methotrexate-resistant sub-lines HT29-12 and HT29-21, IM counteracted butyrate-mediated proliferation inhibition, which was abrogated by NDGA. In all the investigated cell lines, proliferation inhibition was most effectively achieved under the combined application of butyrate with IM and NDGA, suggesting that inhibition of both cyclooxygenase (COX) and lipoxygenase (LOX) isoenzymes is needed for proliferation inhibition by NSAIDs in tumour cells.
