LGR6 protects against myocardial ischemia-reperfusion injury via suppressing necroptosis.

ABSTRACT: Regulated necrosis (necroptosis) and apoptosis are important biological features of ischemia-reperfusion (I/R) injury. However, the molecular mechanisms underlying myocardial necroptosis remain elusive. Leucine rich repeat containing G protein-coupled receptor 6 (LGR6) has been reported to play important roles in various cardiovascular disease. In this study, we aimed to determine whether LGR6 suppresses I/R-induced myocardial necroptosis and the underlying molecular mechanisms. We generated LGR6 knockout mice and used ligation of left anterior descending coronary artery to produce an in vivo I/R model. The effects of LGR6 and its downstream molecules were subsequently identified using RNA sequencing and CHIP assays. We observed significantly downregulated LGR6 expression in hearts post my
