Homogenates from NF and failing (ICM; DCM) RV and LV myocardium were solubilized in a SDS-buffer and then separated electrophoretically. The immunological detection of PP2A subunits was performed by use of specific antibodies directed against Cα/β (a), B56α (b), and Aα (c). The statistical summarization of quantification is depicted as PhosphorImager units. Signals were standardized to calsequestrin (CSQ). *P < 0.05 vs. NF; ⁺ P < 0.05 vs. RV
