Serum markers of apoptosis decrease with age and cancer stage
Figure 4.Serum total cytochrome c levels. The levels of total cytochrome c in 204 normal subjects were determined as depicted in Figure 3. The frequency distribution of the values across the subjects was analyzed (a). The levels of total cytochrome c in all subjects by gender was plotted (b). The sample population was segregated by gender and the levels of serum cytochrome c as a function of donor age for female (c) and male (d) subjects were plotted.
