Shuyusan-containing serum protects SH-SY5Y cells against corticosterone-induced impairment

The Chinese herb Shuyusan, whose main constituent is jasminoidin, has been shown to protect SH-SY5Y cells against corticosterone-induced damage. SH-SY5Y cells injured by 400 μmol/L cor- ticosterone were treated with 5 and 30 μg/mL Shuyusan-containing serum. Results revealed that Shuyusan-containing serum elevated the survival rate of SH-SY5Y cells, reduced Bax expression, increased Bcl-2 expression, markedly elevated brain-derived neurotrophic factor mRNA expression, and blocked cell apoptosis. Moreover, the effect of high-dose （30 μg/mL） Shuyusan-containing se- rum was more remarkable. Therefore, Shuyusan-containing serum appears to protect SH-SY5Y cells against corticosterone-induced impairment by adjusting the expression of apoptosis-associ- ated proteins and brain-derived neurotrophic factor. Moreover, high-dose Shuyusan-containing se- rum has a protective effect on high-dose corticosterone-induced impairment.
