Myofilament 2D-DIGE ex vivo stretch left ventricles. (A) Representative 2D gels of ex vivo stretch left ventricles. From top to bottom: merged, WT stretch (green), β-arrestin 1 KO stretch (blue), and β-arrestin 2 KO stretch (red). (B–H) Average ratios of phosphorylated to total tropomyosin (P-TM/T-TM) (B), P1 to myosin light chain 2 (P1-MLC-2/MLC-2) (C), P2 to myosin light chain 2 (P2-MLC-2/MLC-2) (D), total P to myosin light chain 2 (P-MLC-2/MLC-2) (E), P1 to troponin T3 (P1-TnT3/TnT3) (F), P1 to troponin T4 (P1-TnT4/TnT4) (G), and P to troponin T (P-TnT/TnT) (H). n = 5 separate left ventricles per genotype and condition (control and stretch). Statistical comparisons were made using one-way ANOVA with Bonferroni’s multiple comparison test. No significant differences were noted between the WT and KO mice. Error bars reflect SEM. βarr1KO, β-arrestin 1 KO; βarr2KO, β-arrestin 2 KO; C, control; Str, ex vivo stretch.
