Fig. 7. Effect of SFN on the activation of Nrf2 gene via PI3K/Akt signalling pathway in control and As treated rats. Lane 1. Control (Normal DNA), Lane 2. As Control (5 mg/kg BW) (increased DNA damage), Lane 3. SFN + As (80 mg/kg BW) + Ar (5 mg/kg BW) (mild DNA damage). Lane 4. Control + SFN (80 mg/kg BW) (Normal DNA). Values not sharing a common or same alphabet letter (^a-f) and they differ significantly at P<0.05 (Duncan's multiple range test).
