Figure 6 Protein concentration of: A) SERCA2a, B) calsequestrin, C) pentameric phospholamban, and D) monomeric phospholamban, between junior (60 years) and senior (>60 years). SERCA2a and pentameric phospholamban were both decreased in the senior myocardium (*p > 0.05 vs. junior age group). Calsequestrin and monomeric phospholamban did not differ between these two groups (p > 0.05).
