Histone deacetylase inhibition induces apoptosis and autophagy in human neuroblastoma cells.

Abstract:

:Neuroblastoma (NB) is the most common solid extracranial tumor in children. Here we showed that trichostatin A, a histone deacetylase inhibitor (HDACi), decreases cell viability in three NB cell lines of different phenotypes. The treatment leads to G2/M-phase arrest, apoptosis and autophagy. Autophagy induction accompanies apoptosis in the most proliferative, N-Myc overexpressing cells. In contrast, autophagy precedes apoptosis and acts as a protective mechanism in the less proliferative, non-N-Myc overexpressing cells. Therefore, the autophagy induction is a relevant event in the NB response to HDACis, and it should be considered in the design of new treatments for this malignancy.
