Effects of MeHg, BSO and GSH on the viability of RA-treated P19 cells (a) and SH-SY5Y cells (b). Cells cultured for 6 days in the differentiation media were pre-treated with 100 μM BSO for 17 h or 1 mM GSH for 1 h followed by exposure to 1 μM MeHg for 24 h. Cell viability was assessed with the PrestoBlue assay that measures cellular metabolic reduction, and extracellular LDH activity assay. Data are means ± SEM of n = 6 independent experiments. For the PrestoBlue assay, data are expressed as percentage of non-treated or 0.1% DMSO vehicle-treated cells. For the LDH assay, the data are presented as percentage of total cell death (cells treated with 2% Triton X-100). Statistical analysis was undertaken using one-way ANOVA with post hoc Bonferroni’s multiple comparisons test: *p < 0.05, **p < 0.01, and ****p < 0.0001 (the effect of the treatment compared to the corresponding vehicle control, or the effect of the combination of MeHg + GSH or MeHg + BSO compared to MeHg per se). ND = not determined
