What is SAHA-sensitized prostate cancer cells to TNFα-related apoptosis-inducing ligand (TRAIL): Mechanisms leading to synergistic apoptosis about?
## Abstract Treatment of cancer cells with histone deacetylase inhibitors (HDACi) such as suberolylanilide hydroxamic acid (SAHA) activates genes that promote apoptosis. To enhance proapoptotic efficiency, SAHA has been used in combination with radiation, kinase inhibitors and cytotoxic drugs. Although several prostate cells respond to TNFα‐Related Apoptosis‐Inducing Ligand (TRAIL), LNCaP are resistant. This model system was utilized to examine the advantages of combined treatment with SAHA and TRAIL. In LNCaP cells, TRAIL induced synergistic apoptosis when combined with even with the lowest dose SAHA. Treatment with caspase inhibitor confirmed that SAHA‐induced apoptosis was mediated through caspases. In addition to induction of apoptosis, SAHA and TRAIL decreased the levels of proapoptotic proteins IKKα, IKKβ and IKKγ, suggesting that SAHA treatment may reduce the activity of NFκB. However, assay for NFκB luciferase reporter activity showed highly significant increase in SAHA‐treated cells, supporting earlier suggestions that HDACi promotes NFκB transcriptional activity. Further analyses to determine the mechanisms by which the combination of SAHA and TRAIL led to synergistic apo
