Aim of the studySYJN is a Chinese herbal formula that contains four herbs: Bupleurum chinense DC., Curcuma aromatica Salisb., Perilla frutescens (L.) Britt., and Acorus tatarinowii Schott. Previous studies conducted in our laboratory have revealed an antidepressant-like effect of the formula in chronic unpredictable stress (CUS)-induced depression model in rats. The present study aimed to investigate whether neurotrophin-3 (NT-3) and nerve growth factor (NGF) are involved in the antidepressant-like action of SYJN by using the same depressive model in rats.Materials and methodsRats were subjected to an experimental setting of CUS. The mechanism underlying the antidepressant-like action of SYJN was examined by measuring protein and mRNA expression of NT-3 and NGF in brain tissues of CUS-exposed rats.ResultsThe results showed that NT-3 protein and mRNA expression in the hippocampus and frontal cortex were significantly decreased in CUS-treated rats. CUS treatment also significantly decreased NGF protein and mRNA expression in the frontal cortex of the animals. Daily intragastric administration of SYJN (1300 or 2600 mg/kg/day) during the 4 weeks of CUS significantly suppressed these changes induced by CUS.ConclusionThe results suggest that the antidepressant-like activity of SYJN is likely mediated by the increases in NT-3 and NGF expression in brain tissues.
Neurotrophin-3 (NT-3) and nerve growth factor (NGF) are both involved in the antidepressant-like action of SYJN.Figure optionsDownload as PowerPoint slide
