Figure 6. (A) Lipid peroxidation increases significantly in parallel to increased DNA damage in post pubescent males (p<0.0001).

Figure 6

The subjects were aged between 15–77 years (n = 19). Spearman's correlation coefficient, r = 0.7209. An exponential (first-order) least squares fit was used to generate the nonlinear trend line. (B) PARP activity decreases in line with a decline in NAD+ levels in post pubescent male subjects (p = 0.0149). . The subjects were aged between 15–77 years (n = 19). Pearson's correlation coefficient,r = −0.5491 An exponential (first-order) least squares fit was used to generate the nonlinear trend line. (C) Correlation between NAD+ levels and SIRT1 activity in post pubescent male subjects. The subjects were aged between 15–77 years (n = 19). The correlation is not of statistical significance (p = 0.9829). Pearson's correlation coefficient,r = −0.005263.
