| pubmed-article:20811699 | pubmed:abstractText | Although p53 is intact in most cases of retinoblastoma, it is largely inactivated by the ubiqutin-proteasome system through interaction with murine double minute 2 (MDM2) and murine double minute X (MDMX). The present study showed that the histone deacetylase (HDAC) inhibitors valproic acid (VPA) and depsipeptide (FK228) synergistically enhanced ionizing radiation (IR)-induced apoptosis, associated with activation of caspase-3 and cleavage of poly(ADP-ribose) polymerase in Y79 and WER1-Rb1 human retinoblastoma cells. Both VPA and FK228 enhanced IR-induced phosphorylation of histone H2AX on Ser139 preceding apoptosis. Exposure of cells to IR in the presence of VPA or FK228 induced the accumulation of p53 acetylated at Lys382 and phosphorylated at Ser46 through the reduction of binding affinity with MDM2 and MDMX. These results suggest that acetylation of p53 by HDAC inhibitors is a promising new therapeutic target in refractory retinoblastoma. | lld:pubmed |
