Fig. 3: Post-mortem changes in the heart and its soluble and ECM subcellar compartment.

a Volcano plot highlights differentially abundant protein in the heart between fresh samples (group 1) and samples incubated for 4 days. b Number of differentially regulated proteins post-mortem in the ECM, soluble fraction, and the total heart. c Distribution of protein alterations across various time points compared to fresh samples. d Scatter plot of protein changes in the subcellular fraction of the heart comparing group 2 and fresh samples. P values were calculated using a two-sided Student t-test using equal variance and a p < 0.05 was considered as significant. N = 5 for all mouse proteomics samples.
