Evaluation of calcium handling proteins and cardiac hypertrophy-related signaling proteins. (A) Representative immunoblots for sarcoplasmic/endoplasmic reticulum calcium ATPase 2a (SERCA2a), phospholamban (PLN), c-jun N-terminal kinase 1 (JNK1), p38, endothelin receptor A (ET-A) and Akt. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and vinculin were used as the loading control. (B) Densitometry quantification of the expression level (n = 3–6 for each group).
