Figure 1. Effects of aging and dietary restriction on the levels of 20S proteasome components in the spleen.

Figure 1

The levels of 20S beta (A) and 20S alpha (B) proteasome subunits were analyzed in the spleen of 3 month-old AL, 25 month-old AL, and 25 month-old DR rodents. A representative blot for each analyses is provided, with the molecular weight markers provided on left hand margin of each blot. The graphs represent the mean and S.E.M. of the optical density of the immunoreactivity from 6 animals in each experimental group. *p < 0.05 compared to 3 month old AL animals.
