Figure 4. Effects of aging and dietary restriction on the levels of 20S alpha and 20S beta subunits in the heart.

Figure 4

The level of 20S beta subunits (A) and 20S alpha subunits (B) were analyzed in the hearts of 3 month-old AL, 25 month-old AL, and 25 month-old DR rodents. A representative blot for the analyses is provided, with the molecular weight markers provided on left hand margin of the representative blot. The graph 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. Equal loading was confirmed by commassie staining, data not shown.
