Endothelial KSR2 regulated by genetic variation protects against atherosclerosis through AMPKα1 stabilization.

ABSTRACT: Rationale: The single nucleotide polymorphism (SNP) rs11830157 within the scaffold protein kinase suppressor of Ras 2 (KSR2) locus is strongly associated with the incidence of coronary artery disease (CAD), yet its functional role remains undefined. This study aimed to investigate the potential impact of rs11830157 polymorphism on atherosclerosis and to elucidate the underlying molecular mechanisms. Methods: Dual-luciferase reporter assays, chromatin immunoprecipitation (ChIP), electrophoretic mobility shift assays (EMSA), and CRISPR/Cas9 gene-editing techniques were used to investigate the regulatory role of the SNP rs11830157. To assess the role of KSR2 in atherosclerosis, we utilized global KSR2 knockout mice fed a high-fat diet ad libitum, pair-fed gl
