The effect of food restriction on the nuclear factor-kappa B (NFκB) abundance in the rat cortex during aging. Relative NFκB protein levels in the cytoplasmic fraction (A) and nuclear fraction (B) were determined in rats fed ad libitum (AL) (gray bars) or subjected to food restriction (FR) (black bars). Data are presented as the mean ± SEM of fold changes relative to the values obtained in control, 6-month-old AL animals (n = 6). * p < 0.05 vs. 6-month-old rats; # p < 0.05 vs. age-matched AL rats.
