LC-MS-based phosphoproteomic profiling of the acute phase of myocardial infarction in mice

ObjectiveTo investigate dynamic changes in myocardial protein phosphorylation during the acute phase of myocardial infarction (MI) in mice. MethodsSix 8-week-old C57BL/6J mice were randomly assigned to MI model (n=3) or sham-operated control (n=3) groups. Cardiac tissues were harvested 72 hours post...

description ObjectiveTo investigate dynamic changes in myocardial protein phosphorylation during the acute phase of myocardial infarction (MI) in mice. MethodsSix 8-week-old C57BL/6J mice were randomly assigned to MI model (n=3) or sham-operated control (n=3) groups. Cardiac tissues were harvested 72 hours post-intervention for proteomic analysis. Phosphorylation modifications were systematically characterized using liquid chromatography-mass spectrometry (LC-MS). Bioinformatics analyses included differential phosphorylation screening, functional enrichment, hierarchical clustering, and protein-protein interaction network. ResultsLC-MS identified 1 921 differentially phosphorylated sites (20 tyrosine and 1 901 serine/threonine sites) across 851 proteins. Compared with controls, MI hearts exhibited significant phosphorylation upregulation at 1 545 sites and downregulation at 376 sites (P<0.05). ConclusionsThis study delineates MI-associated phosphorylation dynamics, providing mechanistic insights and potential therapeutic targets for acute MI intervention.
