Depsipeptide (FR901228) Inhibits Proliferation and Induces Apoptosis in Primary and Metastatic Human Uveal Melanoma Cell Lines

Abstract

Purpose. Uveal melanoma (UM) is the most common primary malignant ocular tumor in adults. No effective chemotherapy regimens are available for either intraocular or metastatic uveal melanoma. Therefore, the ability of the histone deacetylase inhibitors (HDACIs), depsipeptide, sodium butyrate (NaB) and trichostatin A (TSA), to induce apoptosis and inhibit cell growth of UM cell lines in vitro was examined.
