Figure 3. Effects of exercise on clusterin and its receptor in middle-aged females. (A) Hippocampal levels of clusterin (Clu) changed in an age-dependent manner in response to exercise (n=5-10, p<0.05). (B) Hippocampal levels of the Clu receptor Plxna4 did not change with age, nor with exercise (n=7-12). *p<0.05 vs respective control in this and following figures.
