Study on neuroprotective effects of Shenjing Fuyuan Decoction through androgen receptor‑mediated downstream signaling pathways in damaged hippocampal neurons in rats
To investigate the potential mechanism by which Shenjing Fuyuan Decoction activates androgen receptor (AR)-mediated regulation of long non-coding RNA growth arrest-specific transcript 5 (LncRNA GAS5) to influence the downstream signaling pathways in the treatment of post-stroke depression (PSD).
Methods
2
Primary hippocampal neurons were isolated from neonatal rat hippocampal tissue. SD rats were treated with intragastric administration of Shenjing Fuyuan Decoction, and serum was collected to obtain blank serum and drug-containing serum. The optimal treatment concentrations of both blank and drug-containing serum were determined. Hippocampal neuron cells in rats were injured using 100 μmol/L hydrogen peroxide (H

) to establish an injury model. The experiment was divided into two sub-experiments. ①In sub-experiment Ⅰ, the four groups were injury model + blank serum group, injury model + AR agonist group, injury model + drug-containing serum group, and injury model + drug-containing serum + AR inhibitor group. Protein expression levels of phosphorylated Akt (p-Akt)/protein kinase B (Akt), phosphorylated phosphoinositide 3-kinase (p-PI3K)/phosphoinositide 3-kinase (PI3K), brain-derived neurotrophic factor (BDNF), and tropomyosin receptor kinase B (TrkB) were detected using Western blot. ②In sub-experiment Ⅱ, the three groups were blank serum group, injury model + blank serum group, and injury model + drug-containing serum group. RNA immunoprecipitation (RIP) was used to detect the interaction between AR protein and
LncRNA GAS5
gene.
Results
2
①The expressions of p-Akt/Akt, p-PI3K/PI3K, BDNF, and
TrkB proteins were significantly higher in the injury model + AR agonist group and the injury model + drug-containing serum group than that in the injury model + blank serum group (
P
<
0.05), and significantly lower in the injury model + drug-containing serum + AR inhibitor group than that in the injury model + drug-containing serum group (
P
<
0.05). ②RIP results showed that AR protein interacted with the
LncRNA GAS5
gene, indicating that
LncRNA GAS5
plays an important negative regulatory role in the expression of AR and its signaling pathway.
Conclusion

Shenjing Fuyuan Decoction has a protective effect on H

-induced hippocampal neuron injury in SD rats, with part of its mechanism of action likely involving the activation of the AR-mediated GAS5 regulatory axis, which in turn activates the BDNF/TrkB/PI3K/Akt signaling pathway.
