Article Title: Effect of prolonged voluntary wheel running on oxidative stress and defence mechanisms in cortex and hippocampus of healthy female rats
doi: 10.1113/ep092815
Figure Lengend Snippet: FIGURE 6 Mitochondrial BER. (a) Representative immunoblots of target proteins in mitochondrial extracts from cortex and hippocampus. Proteins probed for are shown on the left. APE1, apurinic/apyrimidinic endonuclease 1; HSP60, heat shock protein 60. (b) Representative gel from in vitro AP endonuclease activity assay with mitochondrial extracts from hippocampus. S, substrate; P, product; AP, oligonucleotide with AP site; C, control oligonucleotide without a lesion. (c–f) All values are normalized to HSP60 (mitochondrial loading control) and set relative to the sedentary group mean. Bars represent means ± SD. Differences were evaluated by Student’s unpaired t-test (c) or Mann–Whitney U-test (d–f). (c) n = 10 and 8 for sedentary and running group, respectively. (d) n = 10 and 7 for sedentary and running group, respectively. (e) n = 9 and 8 for sedentary and running group, respectively. (f) n = 7 and 9 for sedentary and running group, respectively. One outlier was excluded from the analysis in the sedentary group for (e, f). Other discrepancies in sample size are due to technical issues in assays or insufficient yield from mitochondrial purification. BER, base excision repair.
