Overexpression of Histone deacetylases as key players in mediating gene expression have been demonstrated to be involved in numerous types of cancer and some isoforms also in neurological, inflammatory and viral pathologies. There is large evidence that histone deacetylase inhibitors can be applied for their treatment. This review summarizes recent clinical aspects and efforts in the drug devel...

Mutant p53 is a cancer-specific target for pharmacologic intervention. We show that histone deacetylase inhibitors such as FR901228 and trichostatin A completely depleted mutant p53 in cancer cell lines. This depletion was preceded by induction of p53-regulated transcription. In cells with mutant p53 pretreated with histone deacetylase inhibitors, DNA damage further enhanced the p53 trans-funct...

Histone deacetylase inhibitors represent a promising new class of compounds for the treatment of cancer. Inhibitors of this kind currently under clinical evaluation mainly target the classical (Rpd3/Hda1) family of histone deacetylases. Of particular note, the U.S. Food and Drug Administration recently approved the first histone deacetylase inhibitor (Zolinza: Merck and Co., Whitehouse Station,...

Histone deacetylase inhibitors are promising agents for various T-cell lymphomas, including cutaneous T-cell lymphoma, peripheral T-cell lymphoma, and adult T-cell lymphoma/leukemia. CCR4 is an important therapeutic target molecule because mogamulizumab, an anti-CCR4 antibody, has shown promising efficacy against various T-cell lymphomas. In this study, we examined the in vitro synergistic effe...

BACKGROUND Fibroblast growth factor 21, a novel regulator of glucose and lipid metabolism, has robust protective properties in neurons. However, its expression and function in glia are unknown. Valproic acid, a mood stabilizer and anticonvulsant, is a histone deacetylase inhibitor and a dynamic gene regulator. We investigated whether histone deacetylase inhibition by valproic acid and other inh...

The main goal of our study has been to analyze the efficiency of new anticancer drugs, specifically histone deacetylase inhibitors, in tumor cells bearing a multidrug resistance phenotype. We report that the histone deacetylase inhibitors, Trichostatin A and Suberoylanilide Hydroxamic Acid (SAHA), dramatically reduce cell viability and promote apoptosis in different drug-resistant cells, affect...
