Figure 4: MeHg activates Nrf2 in SH-SY5Y cells. (a) Cells were exposed to MeHg (1, 2, 4, or 8 μM) for 6 h, and the total cell lysates (20 μg) were subjected to western blotting with the antibodies indicated. (b) Cells were exposed to MeHg (0.25 or 0.5 μM) for 6, 12, or 24 h, and the total cell lysates (20 μg) were subjected to western blotting with the antibodies indicated. Reprinted from Toyama et al.
