BDNF and neuroblastoma: Neuroblastoma cells were treated for 3 h with KCl 20 mM alone or in the presence of PHA-680632 aurora-kinases inhibitor, or 50 nM GF 109203X a selective inhibitor of protein kinase C (PKC) which does not regulate BDNF translation in neuroblastoma cells (Heikkila et al., 1993).
