C60 Fullerene Prevents Restraint Stress-Induced Oxidative Disorders in Rat Tissues: Possible Involvement of the Nrf2/ARE-Antioxidant Pathway

Figure 6

Changes in the nuclear and cytosolic Nrf2 protein expressions in brain and heart tissues after pretreatment of C60FAS (50 μg/kg (F1) and 500 μg/kg (F2)) and acute restraint stress exposure (AS). (a and c) Representative western blot and (b and d) densitometric analysis of Nrf2 protein content. Protein extracts were separated by performing SDS PAGE and subsequently electroblotted onto PVDF membranes. The values of the nuclear and cytosolic Nrf2 proteins were normalized to Lamin B and β-actin, respectively. Final western blot figured as the histogram is expressed as mean percentages (±SD) over control values from two independent experiments. The control values are taken as 100%. Statistically significant differences are indicated as vs. control; vs. AS.
