Figure Lengend Snippet: NBE restores de novo cardiac proteome levels to normal. (A) Schematic diagram. NBE was performed 24 h post‐injury. Mice were injected with azido‐homo‐alanine for 5 days starting with the onset of injury. Heart samples were harvested at 5 days post injury. (B) Principal component analysis (PCA) plots of the protein expression profile of all treatment groups showed clear separation of sham and I/R controls, with clustering of I/R + NBE group in sham. Confidence ellipses at 50%, 80%, and 95% intervals are overlaid to indicate group variance. (C) Volcano plots identified differentially expressed proteins (DEPs) in I/R versus Sham controls and I/R + NBE versus I/R controls. Proteins highlighted in red are significantly upregulated while proteins highlighted in blue are significantly downregulated (adjusted p ‐value < 0.05) (horizontal dotted line), and log2 fold change > 2 (vertical dotted line). (D) Venn diagram showed the 12 overlapping DEPs between the upregulated proteins after injury and their downregulation after NBE treatment. (E) Heatmap visualized the expression of the 12 overlapping proteins across all groups. (F, G) Gene Ontology overrepresentation analysis of the 12 overlapping DEPs highlighted top 10 biological processes and molecular function, respectively. (H) cirFunMap visualization of KEGG enriched pathways of the 12 overlapping proteins.
Article Snippet: After injury, mice were injected intraperitoneally with azido‐homo‐alanine (Jena Biosciences CLK‐AA009, 0.02 mmol/kg) daily for 5 days.
