Age-Dependent Protein Expression of Serine/Threonine Phosphatases and Their Inhibitors in the Human Cardiac Atrium

Figure 2

Correlation of PP2C (a), PP2Ac (c), I1PP2A (e), and I2PP2A (g) expression with age. Ordinates are expression data normalized to CSQ in arbitrary phosphoimager units versus age (abscissae). (b), (d), (f), and (h) Expression data are combined to four age groups and are given as means ± SEM; (compare with Table 1). indicates a significant correlation, vs. all other age groups, and vs. age group 60–69.
