ABCA1-eRNA as a novel Epigenetic Regulator, promotes cholesterol efflux, Attenuates Macrophage Inflammation and Severity of Coronary Artery Disease [ABCA1 RNA-seq]

Project description:Enhancer RNAs (eRNAs) are emerging as powerful regulators of various biological processes, but the underlying epigenetic regulatory mechanisms of these molecules in cholesterol homeostasis remain elusive. Using an integrated genomic screen, we identified an intragenic super-enhancer derived long noncoding RNA embedded in the ATP-binding cassette transporter A1 (ABCA1) gene, named ABCA1-seRNA, which is required for activation of RXRα/LXR mediated gene expression. Deficiency of ABCA1-seRNA abolished cholesterol efflux, promotes Macrophage Inflammation, and that haven been causally Susceptibility to Coronary heart disease. Mechanistically, ABCA1-seRNA affects cholesterol efflux by interaction with MED23 and recruitment RXR and LXR to mediate ABCA1 transcription in cis. Furthermore, ABCA1-seRNA repression inflammatory response and attenuated macrophage M1 polarization and migration through ubiquitination of a NF-B subunit P65. Our results suggest that super-enhancer derived long noncoding RNA, as a novel Epigenetic Regulator, are critical components to maintain cholesterol homeostasis and inflammation restriction, represent an attractive therapeutic target to reduce Atherosclerotic cardiovascular disease (ASCVD).

E3 ubiquitin ligase Listerin regulates macrophage cholesterol efflux and atherosclerosis by targeting ABCA1

Project description:Atherosclerosis arises from disrupted cholesterol metabolism, notably impaired macrophage cholesterol efflux leading to foam cell formation. Through single-cell and bulk RNA sequencing, we identified Listerin as a regulator of macrophage cholesterol metabolism. Listerin expression increased during atherosclerosis progression in humans and rodents. Its deficiency suppressed cholesterol efflux, promoted foam cell formation, and exacerbated plaque features (macrophage infiltration, lipid deposition, necrotic cores) in macrophage-specific knockout mice. Conversely, Listerin overexpression attenuated these atherosclerotic manifestations. Mechanistically, Listerin stabilizes ABCA1, a key cholesterol efflux mediator, by catalyzing K63-linked polyubiquitination at residues K1884/K1957, countering ESCRT-mediated lysosomal degradation of ABCA1 induced by oxLDL. ABCA1 agonist Erythrodiol restored cholesterol efflux in Listerin-deficient macrophages, while ABCA1 knockout abolished Listerin's effects in THP-1 cells. This study establishes Listerin as a protective factor in atherosclerosis via post-translational stabilization of ABCA1, offering a potential therapeutic strategy targeting ABCA1 ubiquitination to enhance cholesterol efflux.
