Cisplatin causes a dose limiting peripheral neuropathy, however, the biological mechanism by which this occurs is unknown. Murine N1E.115 neuroblastoma cells and neural crest derived pigment cells have similar transport mechanisms to human neural cells and were used to study the effect of cisplatin on cellular transport. Cisplatin reduced both the number and velocity of organelles moving in the anterograde and retrograde direction, compared to control cells. Cisplatin induced inhibition of transport was prevented by the simultaneous administration of ACTH4-9. This analog alone had no effect on N1E.115 organelle, or erythrophore granule, movement. In both N1E.115 and pigment cells cisplatin inhibited transport within 1 h of exposure to the drug. The degree of inhibition did not increase significantly if pigment cells were incubated in cisplatin for 48 h compared to acute exposure. Microtubules in both pigment cells and N1E.115 neurites retained their structural integrity suggesting that factors other than changes in gross microtubule morphology are responsible for cisplatin neurotoxicity. Cisplatin reduces N1E.115 neurite growth after 48 h incubation but this can be prevented by simultaneous use of ACTH4-9. This study demonstrates for the first time that cisplatin and ACTH4-9 affect fast axonal transport by specific mechanisms which appear related to their observed neurotoxic and neuroprotective roles, respectively.
