Figure 3. Effect of SFN on translocation of Nrf2 into cell nucleus.

Nrf2 was detected in nuclear extracts from cells exposed to SFN (0, 2.5, 5 and 10 µM) for 24 h, using a Western blot assay. Control cells were treated with DMSO (0.1%). A: immortalised human hepatocyte HHL-5; B: human heptoma HepG2 cells.
