Effect of ovariectomization on Alzheimer-like phosphorylation of Tau in hippocampus of rats / 中国病理生理杂志

ABSTRACT

AIM: To explore the effect of ovariectomization on Alzheimer-like phosphorylation of Tau in hippocampus of Sorague-Dawlery rats. METHODS: An animal model was developed using ovariectimized (OVX) rats, and the phosphorylation of Tau protein was measured by Western blot. RESULTS: The levels of phosphorylated Tau at PHF-1epitope were elevated in ovariectimized rat brain hippocampus 4 weeks and 8 weeks after ovariectomization, when compared with sham-OVX rats (P0.05). CONCLUSION: Ovariectomization may induce Alzheimer-like hyperphosphorylation of Tau protein in brain hippocampus of rats. [
