In an animal model of myocardial ischemia/reperfusion, DEX alleviated myocardial mitochondrial apoptosis through a pathway involving the lncRNA HCP5/miR-29a/MCL1 axis and activation of Janus kinase 2/signal transducer and activator of transcription 3 signaling (Deng et al., 2022). Here, JAK2 is linked to myocardial ischemia.
