Nonselective HDACis enhance neurotoxicity of cisplatin and camptothecin. Rat cortical neurons were treated as indicated. MTT assay was performed at 24 h after starting co-treatments. Combinations of the pan-HDACis TSA or SAHA with the DNA damaging anticancer drugs camptothecin or cisplatin resulted in pronounced reductions of neuronal survival. Data represent means ± SD from five (a), or two (b) independent experiments; in each experiment, six sister cultures were used per each condition; **p <0.01; ***p < 0.001; NS p >0.05 (u test)
