Uveal melanoma is the most common intraocular malignancy in adults, representing approximately 3% of all melanoma cases. Despite progress in chemotherapy, radiation and surgical treatment options, the prognosis and survival rates remain poor. Acetylation of histone proteins causes transcription of genes involved in cell growth, DNA replication and progression of cell cycle. Overexpression of histone deacetylases occurs in a wide spectrum of malignancies. Histone deacetylase inhibitors block the action of histone deacetylases, leading to inhibition of tumor cell proliferation. This article reviewed the potential therapeutic effects of histone deacetylase inhibitors on uveal melanoma. MEDLINE database was used under the key words/phrases: histone deacetylase, inhibitors, uveal melanoma and targeted therapies for uveal melanoma. A total of 47, English articles, not only referring to uveal melanoma, published up to February 2018 were used. Valproic acid, trichostatin A, tenovin-6, depsipeptide, panobinostat (LBH-589), vorinostat (suberanilohydroxamic acid) entinostat (MS-275), quisinostat, NaB, JSL-1, MC1568 and MC1575 are histone deacetylase inhibitors that have demonstrated promising antitumor effects against uveal melanoma. Histone deacetylase inhibitors represent a promising therapeutic approach for the treatment of uveal melanoma.
