As considered from lactate dehydrogenase release and 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide reduction, both piperine and shifting from high K+ (25 mM) to low K+ (5.4 mM) were cytotoxic to cerebellar granule neurons.

These results suggest that piperine and low K+ may exert neurotoxic effects on cerebellar granule neurons through different mechanisms. Death of cerebellar granule neurons induced by piperine may be mediated by non-apoptotic mechanisms and may involve membrane lipid peroxidation and/or free radical generation.
