Abstract
Venous graft decay (VGD) occurs in coronary artery bypass grafting (CABG), and ischemia-reperfusion oxidative stress injury during the operation is involved in VGD. To explore the cellular phenotypic changes during this process, a stable oxidative stress model of human saphenous vein endothelial cells (HSVECs) is constructed. Through proteomics and cell experiments, it is found that the expression of BCL2L13 is upregulated during oxidative stress of HSVECs, and BCL2L13 regulated mitophagy through receptor-mediated interaction with LC3 and plays a role in cell protection. During oxidative stress, intracellular o8G epigenetic modification occurs, and the o8G modification of miR-6513-5p causes this molecule to lose its targeted regulation of BCL2L13 and participates in the upregulation of BCL2L13. There is a regulatory pathway of o8G modification-BCL2L13-LC3-mitophagy when oxidative stress occurs in HSVECs.
