Current chemotherapy of advanced non-small cell lung cancer (NSCLC) produces only a modest increase in survival time. New approaches are needed for this disease. The development of lung cancer is associated with silencing tumor suppressor genes that can occur not only by deletion or mutation, but also by epigenetic changes including histone deacetylation of key lysines. Histone deacetylase inhi...
Huntington's disease (HD) is an inherited, progressive neurological disorder that is caused by a CAG/polyglutamine repeat expansion and for which there is no effective therapy. Recent evidence indicates that transcriptional dysregulation may contribute to the molecular pathogenesis of this disease. Supporting this view, administration of histone deacetylase (HDAC) inhibitors has been shown to r...
Oncolytic adenoviruses (OA) have been investigated as virotherapeutic agents for the treatment of cervical cancer and thus far results are promising. However, the cytotoxicity of the viruses requires improvement. The present study demonstrated that this can be achieved by combining ZD55-TRAIL, an OA containing the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) gene, with the hi...
Histone deacetylase inhibitors (HDI) have shown promise as candidate radiosensitizers for many types of cancers. However, the mechanisms of action are not well understood, and whether they could sensitize multiple myeloma (MM) to radiation therapy is unclear. In this study, we show that suberoylanilide hydroxamic acid (SAHA) at low concentrations has minimal cytotoxic effects, yet can significa...
BACKGROUND Concurrent and sequential administration of combinations of budesonide, bexarotene, suberoylanilide hydroxamic acid (SAHA) and atorvastatin were evaluated in A/J mice for prevention of lung tumors initiated by 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanol, NNK). MATERIALS AND METHODS Individual drugs and their combinations were administered for 26 weeks after NNK initiation. For s...
Histone deacetylase inhibitors (HDACIs) activate genes that promote cell cycle arrest and apoptosis in a number of tumor cells. This study showed that suberoylanilide hydroxamic acid (SAHA), a potent and commonly used HDACI, induced apoptosis in human colon adenocarcinoma HT-29 cells in a time- and dose-dependent manner. This effect was accompanied by the induction of oxidative stress, dissipat...
In our previous research, a novel series of histone deacetylase (HDAC) inhibitors with L-phenylglycine scaffold were designed and synthesized, among which amides D3 and D7 and ureido D18 were far superior to the positive control (suberoylanilide hydroxamic acid [SAHA]) in HDAC inhibition, but were only comparable to SAHA in antiproliferation on tumor cell lines. Herein, further structural deriv...
High grade gliomas are aggressive cancers that are not well addressed by current chemotherapies, in large measure because these drugs do not curtail the diffuse invasion of glioma cells into brain tissue surrounding the tumor. Here, we investigate the effects of suberoylanilide hydroxamic acid (SAHA) on glioma cells in 2D and 3D in vitro assays, as SAHA has previously been shown to significantl...
Suberoylanilide hydroxamic acid (SAHA) is a hydroxamic acid-containing hybrid polar molecule; SAHA specifically binds to and inhibits the activity of histone deacetylase. Although SAHA, like other inhibitors of histone deacetylase, exhibits antitumor effects by increasing expression of genes regulating tumor survival, we found that SAHA reduces the production of proinflammatory cytokines in viv...
Histone deacetylases (HDACs) mediate changes in nucleosome conformation and are important in the regulation of gene expression. HDACs are involved in cell cycle progression and differentiation, and their deregulation is associated with several cancers. HDAC inhibitors have emerged recently as promising chemotherapeutic agents. One such agent, suberoylanilide hydroxamic acid, is a potent inhibit...
