Figure 7.
Total protein levels of different fractions and the overall total protein levels from control and CR mice. Protein levels were determined and were expressed in mg. All values were expressed as mg protein and presented as mean ± SEM (n = 6). Bars within a group, and between groups, that do not share the same letter are significantly different (P < 0.05). The symbol (~) is used to indicate a trend towards an increase or a decrease (P < 0.10) when the difference is not significant. Black bar, M1; Gray bar, M3; Light gray bar, M10; white bars, overall total protein (sum of the three fractions).
