Resveratrol attenuates TAC-induced oxidative stress. Representative images of 4-HNE (top panels) and 8OHdG (middle panels) staining of LV sections at day 28 from sham surgery, TAC, and TAC + resveratrol-treated mice. Areas shown in red are positive for 4-HNE and 8OHdG. Cardiomyocytes were stained green using antitropomyosin I and nuclei in blue were labeled with DAPI. Quantification of the data as described in the Materials and Methods section is shown in the bottom panels. Values are expressed as the mean ± SD. *P < 0.05 was considered statistically significant.
