Fig. 1. The effects of Hg or MeHg on secreted Aβ40. (A) PC12 cells were incubated with different concentrations (10, 100, and 1000 nM) of Hg or MeHg for 48 hr, and Aβ40 levels were measured in culture media by ELISA. (B) PC12 cells were treated with 100 nM of Hg or MeHg for 0, 6, 12, 24, and 72 hr, and Aβ40 levels were evaluated. Quantitative data are stated as mean ± SEM (n = 4); *p<0.05 vs. control, **p < 0.01 vs. control.
