In this study, we investigated the effect of cdk-5 overexpression on tauhyperphosphbrylation in neuroblastoma N2a cells. We demonstrated that Overexpression of cdk-5 whichresulted in a 3.5-fold Cdk-5 activation in thetransfected cells induced a dramatic increase inphosphorylation of tau at severalphosphorylatiosites. Overexpression of cdk-5 led to a reducedstaining with antibody Tau-1 and an enhanced staining with antibody PHF-1, suggestinghy-perphosphorylation of tau at Serl99/202 and Ser396/404 sites. It implies that in vitroOverexpression of cdk-5 leads to Cdk-5 overactivation and tau hyperphosphorylation may be theunderline mechanism.展开更多
