研究问题
The efficacy of previously used therapies, such as lipid‐lowering drugs, insulin sensitizers, anti‐hyperglycemic agents, and antioxidants, remains uncertain (Ratziu et al. ).；However, the specific role and underlying mechanisms of NMN in NAFLD remain incompletely understood and warrant further in‐depth investigation.；Accordingly, this study aimed to evaluate the hepatoprotective effects of NMN on HFD‐induced NAFLD in mice and to explore the molecular changes associated with NMN treatment.
方法
All experimental procedures were approved by the Animal Ethics Committee of the University of South China (License number: USC 2020031602).；After a week of acclimatization, the mice were randomly divided into three groups (n = 12): control group (Ctrl), NAFLD group, and NAFLD+NMN group.；At the experimental endpoint, H&E staining revealed hepatocellular steatosis, and Oil Red O staining showed increased neutral lipid accumulation in hepatocytes.；Serum lipid metabolism levels were measured using commercial assay kits according to the manufacturer's instructions.
核心结论
The course of NAFLD is variable, with NAFLD potentially progressing to cirrhosis and hepatocellular carcinoma, making it a major cause of severe liver disease and a significant public health concern (Paul Angulo ).；The efficacy of previously used therapies, such as lipid‐lowering drugs, insulin sensitizers, anti‐hyperglycemic agents, and antioxidants, remains uncertain (Ratziu et al. ).；In recent years, NMN, as an important intracellular precursor of NAD+, has garnered significant attention from the research community. ‖ 结论：These findings extend our understanding of the molecular changes associated with the protective effects of NMN in NAFLD beyond its known role as an NAD+ precursor.
局限
Although our study has provided valuable insights into the protective role of NMN in NAFLD, several limitations should be considered.；Future studies should further explore these additional mechanisms.

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
