Figure 4: A: Cellular AKR1B10 protein in HepG2, BEL-7402, PLC and RBE cells was determined by Western Blotting. B: AKR1B10 activity in cell lysate from RBE cells treated with 200 μM EPS, 160 μM PA, or a combination of 200 μM EPS and 160 μM PA for 30 minutes was investigated (#, P<0.05 versus *; #, P<0.05 versus +; *, P<0.05 versus **; +, P<0.05 versus **).
