Effects of resveratrol on apoptotic cell death in the livers of aged mice treated with Con A. (a) Protein lysates were analyzed using Western blotting with the antibodies against Bcl-2, Bax and cytochrome C (cyt C). Data are means ± SEMs from three independent measurements. (b) TUNEL staining with FITC fluorescein label. DAPI is the nuclear stain. The images are shown at 200 × magnification, with the upper right grid at 400 × enlargement for selected squares. The length of scale bar was indicated as 200 μm. (c and d) The hepatic activity of caspase 3 and caspase 8 (n = 7 in each group). Different letters denote statistically significant differences (p < 0.05) between groups.
