ABSTRACT
This study aimed at exploring the molecular mechanism of fibroin peptide in preventing the Aβ25-35-induced neuronal damages in SH-SY5Y cells.MTT was used to detect the effect of fibroin peptide on the changes of the Aβ25-35-induced injuries in SH-SY5Y cells;Western blot was employed to detect the effect of fibroin peptide on the changes of the Aβ25-35-induced hyperphosphorylation of Tau in SH-SY5Y cells;DCFH-DA probe method was used to detect the effect of fibroin peptide on the Aβ-induced production of intracellular reactive oxygen species (ROS) in SH-SY5Y cells.The results indicated that fibroin peptide could improve the activity of the PP2A and inhibit the activity of GSK-3β to decrease the hyperphosphorylation of Tau induced by Aβ25-35.Fibroin peptide could significantly prevent the Aβ25-35-induced neuronal damages and multisite Tau hyperphosphorylation.In addition,fibroin peptide could also reduce oxidative damage to protect neurons by significantly decreasing the Aβ25-35-induced production of intracellular ROS.
