Multi-omics analysis of early reperfused ischemic heart reveals ERRß/? activation protects against acute myocardial infarction injury [bulk RNA-seq]

The rats were subjected to left anterior descending (LAD) coronary artery ligation for 1 hour, 6 hours (MI1h and MI6h) and 24 hours (MI24h) along with Sham controls (Sham), and 1-hour, 6-hour ischemia followed by reperfusion (MI1h/R and MI6h/R, mimicking early time reperfusion (ETR) and late time reperfusion (LTR), respectively) followed by heart tissue collection 24 hours post MI to mimic the MI/R injury in AMI patients and pretreatment with FDA-approved PPARa agonist fenofibrate for each group. Overall design: Bulk RNA sequencing performed with rats subjected to left anterior descending (LAD) coronary artery ligation for 1 hour, 6 hours (MI1h and MI6h) and 24 hours (MI24h) along with Sham controls (Sham), and 1-hour, 6-hour ischemia followed by reperfusion (MI1h/R and MI6h/R, mimicking early time reperfusion (ETR) and late time reperfusion (LTR), respectively) followed by heart tissue collection 24 hours post MI to mimic the MI/R injury in AMI patients and pretreatment with FDA-approved PPARa agonist fenofibrate for each group.
