HlncRNA-1 integrates the hepatic circadian clock with lipid metabolism by targeting Hdlbp
Ontology highlight
ABSTRACT: The circadian rhythm and lipid metabolism in organisms are tightly coupled, yet the role of lncRNAs in the integration of these two important physiological processes remains unclear. In this study, we identified a liver-specific lncRNA named HlncRNA-1, which regulates lipid metabolism while responding to circadian rhythms. Mice overexpressing HlncRNA-1 exhibited suppressed liver fat accumulation under conditions of both nutrient surplus and deficiency, along with improved insulin sensitivity. In summary, HlncRNA-1 serves as a regulatory conduit that translates circadian clock cues into metabolic outputs, orchestrating circadian control of hepatic lipid metabolism, and activating this lncRNA represents a viable target for precisely intervening in lipid metabolic disorders induced by circadian disruption.
