摘要: 本实验基于D-半乳糖(D‑galactose,D-gal)诱导的小鼠及细胞衰老模型,探究荷叶碱(nuciferine,NF)改善衰老相关肾功能紊乱的作用机制。结果表明,5 mg/kg和10 mg/kg NF干预能够显著缓解D-gal诱导衰老小鼠的肾功能障碍、肾纤维化、细胞凋亡和炎症;细胞实验结果进一步表明,60 μmol/L NF处理能够显著抑制D-gal诱导的HK-2细胞衰老、纤维化与凋亡;同时,NF能够有效抑制血管紧张素转换酶(angiotensin-converting enzyme,ACE)活性,且能通过调控肾素-血管紧张素系统改善衰老诱导的肾功能紊乱,说明NF可通过调节ACE活性改善衰老诱导的肾损伤。综上,NF可作为一种潜在的天然膳食补充剂,有望用于改善衰老引起的肾功能紊乱,本研究可为基于NF的功能性健康产品开发提供理论依据。

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.
