MeHg and HgCl2 cause dose-dependent decreases in cell viability. SH-SY5Y cells and NPCs were exposed to various concentrations of methylmercury (MeHg), mercury chloride (HgCl2) or vehicle (DMSO) for 5 h, followed by an MTT assay to determine mitochondrial activity as a proxy for cell viability. MeHg was more potent than HgCl2 at eliciting cell death in both cell types and NPCs were more sensitive than SH-SY5Y cells to the toxic effects of either compound. Results are given as mean +/- SEM, vehicle control = 100%, from at least 3 independent replicates per condition.
