AIM
To investigate the effects and mechanisms of S-adenosylmethionine (SAM) from deer antler on improving depression-like behaviors in chronic unpredictable mild stress (CUMS) mice.
METHODS
The CUMS method was used to establish a mouse depression model. The relationship between SAM and HIF-1α was analyzed by small molecule-protein docking and molecular dynamics simulation.
RESULTS
Network pharmacology analysis showed that the effect of SAM is related to HIF-1α. When shRNA-HIF-1α was used to silence the expression of HIF-1α, the effect of SAM was inhibited. The improvement of depression-like behaviors in mice was not significant, and inflammatory factors were no longer further downregulated.
CONCLUSION
SAM can improve depression-like behaviors in CUMS mice and enhance their mobility. SAM inhibits neuroinflammation and glycolysis, and also suppresses the activation of microglia.
目的
探讨鹿茸中S-腺苷甲硫氨酸（SAM）改善慢性不可预测性轻度应激（CUMS）小鼠抑郁样行为的作用及机制。
方法
采用CUMS法建立小鼠抑郁模型。通过小分子-蛋白质对接和分子动力学模拟分析SAM与低氧诱导因子-1α（HIF-1α）之间的关系。
结果
网络药理学分析表明，SAM的作用与HIF-1α有关。当使用shRNA-HIF-1α沉默HIF-1α表达时，SAM的作用受到抑制。小鼠抑郁样行为的改善不明显，炎症因子也不再进一步下调。
结论
SAM可改善CUMS小鼠的抑郁样行为并增强其活动能力。SAM抑制神经炎症和糖酵解，还可抑制小胶质细胞的激活。
