Figure 4From: Life-long spontaneous exercise does not prolong lifespan but improves health span in micePlasma oxidative stress biomarkers at different survival time points (3, 20, 26 and 29 months old) in the longevity curve. A) shows a representative Western blot and the densitometric quantification of protein carbonyls in plasma. Values were normalized to those observed in the samples obtained from the three-month-old group, which was assigned a value of 100%. B) shows plasma lipid peroxidation determined as malondialdehyde {MDA). Values are shown as mean ± SD. (*) indicates P <0.05, (**) indicates P <0.01. Continuous lines show statistically significant differences between the wheel-running animals. Discontinuous lines show statistically significant differences between the sedentary animals.Back to article page
