Phosphorylation of RyR2 and CaMKIIδ in hiPSC-CMs. Western blot (WBs) analysis of Ryanodine receptors (RyR2) phosphorylation status and verification of CaMKII activity in day 90 DMD-vs Control-hiPSC monolayers. (A) Representative WB of CaMKIIδ (B) and analysis normalized for total CaMKII. (C) Representative WB analysis of (D) RyR2 sites of phosphorylation (phospho-specific anti Ser 2814 target of CaMKII and Ser 2808 target of PKA) normalized for GAPDH, *p < 0.05 in ANOVA DMD vs Controls N = 3 (differentiation runs) and n = 2–5 (gel repetitions).
