Inhibition of either PPARα or PPARγ alleviates the hepatoprotective effect of PGC-1α in vivo. (a) The serum levels of aminotransferases were measured in the mice subjected to Ad-PGC-1α, Ad-PGC-1α+MK886, Ad-PGC-1α+GW9662, and Ad-PGC-1α+MK886+GW9662 at 6 h after liver I/R (n = 6). (b) Representative images (200x magnification) of the H&E-stained liver sections (6 h after I/R) were taken, and histopathological scoring of hepatic injury was performed (n = 6). (c) Representative images (200x magnification) of the liver sections (6 h after I/R) stained by TUNEL were taken, and TUNEL-positive cells were counted as described in Materials and Methods (n = 6). (d–f) Caspase-3 activity, DNA fragmentation, and cleaved PARP expression in the mouse livers of each group were assessed by ELISA and western blot analysis at 6 h after I/R (n = 3-6). ∗P < 0.05, ∗∗P < 0.01, and ∗∗∗P < 0.001.
