Figure Lengend Snippet: (A) Schematic timeline of PF1355 treatment and in vivo mouse measurements. (B) Percent left ventricular ejection fraction (%LVEF) at 16-weeks of age. (C) Percent left ventricular fractional shortening (%FS) at 16-weeks of age. Data presented as mean±SEM; n≥5. Statistical significance was determined via two-way ANOVA with Tukey’s multiple comparison test (*P<0.05 and **P<0.01). (D) Representative ECG tracings from PF1355 treated Dsg2 mut/mut , Placebo treated Dsg2 mut/mut , and WT at 16-weeks of age, respectively. Asterisks, ectopic beats. (E) Percent ectopic beats (% Ectopics), (F) R-amplitude, and (G) Q-amplitude at 16-weeks of age. (H) Representative Masson’s trichrome-immunostained hearts from Placebo-treated and PF1355-treated Dsg2 mut/mut at 16-weeks of age. (I) Percent fibrosis at 16-weeks of age. Data presented as mean±SEM; n≥6. Statistical significance was determined via Welch’s t-test for E and one-way ANOVA with Tukey’s multiple comparison test for F,G, and I (*P<0.05). (J) Representative cytokine arrays with legend for key cytokines from Placebo-treated and PF1355-treated Dsg2 mut/mut , and WT mice. (K) Legend of selected cytokines. (L-N) Quantification of selected cytokines normalized to reference band in PF1355-treated and Placebo-treated Dsg2 mut/mut , and WT mice. Data presented as mean±SEM; n=4. *P<0.05, via two-tailed T-test. C5/C5a, Complement Component C5/C5a; CCL11, C-C motif chemokine ligand 11; CCL12, C-C motif chemokine ligand 12; LIX, Lipopolysaccharide-induced CXC chemokine; MCP-1, Monocyte Chemoattractant Protein-1; MIP-α/β, Macrophage Inflammatory Protein-1 alpha/beta; MMP-3, Matrix metalloproteinase-3; MMP-9, Matrix metalloproteinase-9; and NGAL, Neutrophil gelatinase-associated lipocalin. All data presented as mean±SEM. Statistical significance was determined via two-way ANOVA with Tukey’s multiple comparison test for B-C and via two-tailed T-test for E-G, I, and L-N (*P<0.05).
Article Snippet: Cardiac cytokine profiling was conducted using the Proteome Profiler Mouse XL Cytokine Array Kit (R&D Systems, Cat. No. ARY028) as previously described.
