RNA-sequencing of WT and P2Y4 KO pericardial adipose tissue (PAT) 24 hours after left anterior descending artery (LAD) ligation. RNA-sequencing of WT and P2Y4 KO pericardial adipose tissue (PAT) 24 hours after left anterior descending artery (LAD) ligation

We identified differentially regulated genes in the pericardial adipose tissue of wild type (WT) and P2Y4 KO mice, 24 hours after left anterior descending artery (LAD) ligation as a model of myocardial infarction (MI). Differentially regulated genes were involved in metabolism, brown fat cell differentiation, immune response and inflammation. P2Y4 KO mice displayed adipocyte beiging with increased PD-L1 expression and a higher number of regulatory leukocytes in their PAT 24 hours after LAD ligation. Up-regulated genes linked to adipocyte beiging included Ucp1, Cited1 and Prdm16. Overall design: 2 samples were analyzed, a pool of the RNA of 3 WT PAT and a pool of the RNA of 3 P2Y4 KO PAT. PAT was freshly harvested 24 hours after LAD ligation.
