Abstract
The treatment for post-stroke depression (PSD) is mainly based on a therapeutic strategy combining anti-stroke and anti-depressant drugs. In the present study, the therapeutic effect of curcumin on rats with PSD was detected by open field tests and tail suspension tests, as well as the examination of corticosterone and corticotropin-releasing hormone (CRH) levels in the serum and neurotransmitter 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacetic acid (5-HIAA) and dopamine (DA) levels in the hippocampus. Curcumin notably alleviated depression compared to the controls. Furthermore, long noncoding RNA growth arrest-specific transcript 5 (GAS5) enhanced by curcumin contributed to activation of the BDNF/Trkβ signaling pathway to promote the expression of synaptic-related proteins. GAS5 was demonstrated to function as a sponge of miR-10b. GAS5 upregulation by curcumin could reduce miR-10b to compromise the BDNF mRNA levels. Taken together, these results revealed a novel mechanism of curcumin on PSD through the GAS5/miR-10b/BDNF regulatory axis.
