Abstract: This study investigated the protective effects and underlying mechanisms of nuciferine (NF) against aging-related renal dysfunction using mouse and cell models of D-galactose (D-gal)-induced aging and cellular models. The results demonstrated that 5 and 10 mg/kg NF treatment significantly ameliorated renal dysfunction, fibrosis, apoptosis, and inflammation in aging mice. Furthermore, 60 μmol/L NF markedly suppressed D-gal-induced senescence, fibrosis, and apoptosis in HK-2 cells. Meanwhile, NF effectively inhibited angiotensin-converting enzyme (ACE) activity and modulated the renin-angiotensin system, indicating that NF mitigates aging-associated renal injury through the regulation of ACE activity. In summary, NF serves as a potential natural dietary supplement for improving aging-associated renal dysfunction. This study provides a theoretical foundation for the development of NF-based functional health products.
