In these studies, a 2 h/37 °C pre-incubation of SK-N-LP neuroblastoma cells with p38, JNK, NF-ĸB, and caspase inhibitors prior to a 24 h/37 °C incubation with DpC and the inhibitors could slightly, but significantly (p < 0.001-0.05), reduce the cytotoxicity of DpC, while the ERK inhibitor did not have any significant (p > 0.05) effect (Fig. 7b). Here, MAPK8 is linked to neuroblastoma.
