Investigation of mechanism of SchA to decreasing MPP+-induced SH-SY5Y cell damage / 重庆医学

ABSTRACT

Objective To explore the possible mechanism of SchA ,which decreases MPP+induce SH-SY5Y cell damage .Meth-ods Cultured cells were divided into 5 groups ,one as control group ,cultured by free-blood serum media;the other 4 groups were treated with different concentrations of SchA(1 ,3 ,5 μmol/L) and MPP+ (1 mmol/L) for 48 h named model group ,1 ,3 ,5 μmol/L SchA group respetivly .The content of nitric oxide(NO) were measured by NO kit ;The expression levels of total Akt and p-Akt proteins were detected by Western blot .Results Compared with the control group ,the content of NO in group significantly in-creased after MPP+stimulating(P0 .05) .The expression levels of p-Akt in model group significantly lowered ,while SchA(1、3、5 μmol/L) significantly increased the expression levels of p-Akt in comparision with cells in model group .Conclusion Decreasing MPP+ induced SH-SY5Y cell damage of SchA may be related to the content of NO and p-Akt expression .
