[³H]proline incorporation into cardiac fibroblasts under oxidative stress.

A: Cardiac fibroblasts were treated with Cor (300 nmol/L) and/or Epl (1 μmol/L) in the absence of H₂O₂. Untreated cardiac fibroblasts were served as control. n = 8 for each group.

B: Cardiac fibroblasts were treated with Cor (300 nmol/L) and/or Epl (1 μmol/L) in the presence of H₂O₂ (1 μmol/L). Cardiac fibroblasts treated with H₂O₂ alone were served as control. n = 8 for each group.

Control was arbitrarily set to 1. Data are expressed as mean values ± SD.

*P < 0.05 versus control.

†P < 0.05 versus Cor (+) Epl (–).

#P < 0.05 versus Cor (–) Epl (+).

Cor, corticosterone; Epl, eplerenone.
