Abstract
- Aim: We investigated the effects and target of gastrodin (GAS) for treating depression through network pharmacology combined with experimentation.<br />Methods: The therapeutic target and signal of GAS for depression were analyzed by network pharmacology. Depression in mice was mimicked with a chronic unpredictable mouse stress (CUMS) model. Through open field, elevated plus maze, forced swimming, and tail suspension tests, the effects of GAS on the CUMS mice behaviors were examined, and the levels of neurotransmitters were detected. The histopathological changes were assayed by H&E and IHC staining, and the protein expressions were detected by Western blotting. Small molecule-protein docking and molecular dynamics experiments were conducted to simulate the binding mode between GAS and Caspase-3.<br />Results: Network pharmacological analysis revealed that Caspase-3 was the action target of GAS. GAS could improve depression-like behaviors in CUMS mice, elevate their neurotransmitter levels, ameliorate their nerve cell injury, and inhibit their Caspase-3 expression. After knocking out Caspase-3, the effects of GAS were inhibited. Molecular dynamics simulation and small molecule-protein docking found that GAS bound to Caspase-3 at SER25, inhibiting the maturation and activation of Caspase-3.<br />Conclusion: We find that GAS can act as a Caspase-3 inhibitor, which improves depression-like behaviors and nerve cell injury in CUMS mice by inhibiting Caspase-3-mediated apoptosis.<br /> (© 2023 The Authors.
