HNRNPK Lactylation Amplifies Inflammation and Exacerbates Myocardial Ischemia/Reperfusion Injury by Regulating Jag2 Splicing.
BACKGROUND Myocardial ischemia/reperfusion injury triggers profound metabolic reprogramming and lactate accumulation. However, how this metabolic stress regulates inflammatory gene expression remains poorly understood. We hypothesized that lactylation, a lactate-derived posttranslational modification, links metabolic s...
