Romidepsin affects expression of cell cycle regulators. NIH 3T3 (A, C) or RIE-1 (B, D) cells stably expressing the indicated proteins were treated with DMSO (Vehicle) or the indicated concentration of romidepsin for 24 h. Cell lysates were analyzed by western blotting with antibodies to cyclin D1, p21, phospho-S608-Rb, and β-actin (loading control). Data shown are representative of at least two independent experiments.
