Relative contents of protein kinase C (PKC) isozymes (α, β, Ɛ, ꞔ), as well as protein kinase A (PKA), in the right ventricle at 8 weeks of myocardial infarction (MI) in rats.
| Parameters | Sham | Moderate Failure Stage (8 Weeks MI) |
|---|---|---|
| A. Protein kinase C (% of control): | ||
| PKC-α | 100 | 138 ± 11 * |
| PKC-β | 100 | 145 ± 16 * |
| PKC-ℇ | 100 | 126 ± 5 * |
| PKC-ꞔ | 100 | 108 ± 3 |
| B. Protein kinase A | ||
| PKA content (% of control): | 100 | |
| PKA activity (pmol 32P/min/mg protein): | 3600 ± 356 | 3580 ± 375 |
Values are mean ± SE of six experiments. PKC isozymes as well as PKA contents and activity were measured in homogenate. The data are based on the information in our paper, Wang et al., 2003 [34]. * p < 0.05 vs. sham.
