OxPAPC-Mediated lncRNA CYP1B1-AS1 From Dendritic Cells Accelerates Atherosclerosis.

ABSTRACT: Oxidised 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (oxPAPC), dendritic cells (DCs), and long non-coding RNAs (lncRNAs) play crucial roles in atherosclerosis (AS). This study aimed to determine whether oxPAPC-induced DC-derived lncRNAs contribute to AS and to elucidate the underlying regulatory mechanisms. DCs were treated with increasing oxPAPC concentrations to assess transcriptomic changes. RNA sequencing was used to identify differential expression of lncRNAs. ChIP-Seq and RNA pull-down assays were used to assess direct binding between lncRNA CYP1B1-AS1 and NFATC2. The association between CYP1B1-AS1 and CYP1B1 was assessed using Pearson's correlation analysis. Elevated serum oxPAPC levels were confirmed in patients with coronary heart disease. In vitro, sustained oxPAPC
