Figure 1 Mechanistic framework of NR1D1-centered chrono-metabolic regulation in hepatic fibrosis. NR1D1 acts as a central circadian-metabolic node, inhibiting HIF-1α signaling and reducing ammonia-induced hepatic stellate cell activation, thereby mitigating fibrogenesis. Pharmacological and natural compounds (e.g., Hedyotis diffusa, ferulic acid, and dihydroartemisinin) restore NR1D1 expression and downstream pathways. Additional modulatory nodes, including bile acid signaling, non-coding RNAs (MALAT1 and lnc-LFAR1), and PPARα-mediated inflammasome regulation, further refine temporal and metabolic control. HSC: Hepatic stellate cell; ECM: Extracellular matrix.
