VPA對(duì)OA處理的SH-SY5Y細(xì)胞tau蛋白磷酸化水平的影響
[Abstract]:Objective to study the effect of sodium valproate (VPA) on phosphorylation of tau protein in human neuroblastoma cell line (SH-SY5Y) treated with (OA). Methods the effect of OA on the activity of SH-SY5Y cells was observed by MTT. The cell model of tau protein hyperphosphorylation was prepared to detect the effect of OA and VPA on tau protein phosphorylation at Thr231 site. Results the results of MTT showed that when the concentration of OA was more than 40 nmol/L, the cell activity was significantly inhibited, but the effect of OA below this concentration on cell viability was not obvious.; Western blotting results showed that the phosphorylation level of Tau protein in SH-SY5Y cells treated with OA (40 nmol/L,12 h) increased significantly, and the phosphorylation level of Tau protein decreased significantly after treatment with VPA (10 mmol/L) for 12 h. Conclusion VPA can inhibit the hyperphosphorylation of tau protein in SH-SY5Y cells treated with OA.
