The present study aims to observe the change in expression of heat shock protein 90 (HSP90) along with amyloid-β (Aβ) and phosphorylated Tau (p-Tau) protein levels in the hippocampus tissue of Alzheimer's disease (AD) transgenic animal model with age. APP/PS1 transgenic mice at age of 6-, 9- and 12-month and C57BL/6J mice of the same age were used. The cognitive abilities of these animals were evaluated using a Morris water maze.

To uncover the time-dependent expression pattern of gene and encoded protein, protein tyrosine kinase 2 beta(PTK2B), in the brain tissues of transgenic animal models of Alzheimer's disease (AD) and its relationship with the levels of Aβ phosphorylation of Tau (p-Tau) and low density lipoprotein receptor-related protein-1(LRP-1) in blood and brain tissues. In this study, 5-, 10- and 15-month-old APPswe/PS1dE9 double-transgenic mice harboring the genotype of AD confirmed by the gene test were divided into the 5-, 10- and 15-month-old experiment groups, and simultaneously, age-matched C57BL/6J mice were placed into the corresponding control groups, with 8 mice in each group. All mice were subjected to the Morris Water Maze for test of cognitive and behavioral ability.

The aim of the present study was to explore the correlation between ptk2b/PTK2B (protein tyrosine kinase 2 beta, a ptk2b-encoded protein) and the level of low density lipoprotein receptor-related protein-1 (LRP-1), as well as to uncover the relationship between the changes in beta amyloid protein (Aβ) levels in blood and brain and the expression of ptk2b in Aβ-induced cognitive dysfunction mice. A total of 64 3-month-old C57BL/6J mice were divided randomly into the experimental group and control group. All mice underwent the intracerebroventricular (i.

The aim of this study was to investigate the effects of histone deacetylase-6 (HDAC6) on the functional and pathological changes of the amyloid beta (Aβ)-induced cognitive dysfunction rats by regulating protein tyrosine kinase 2 beta (PTK2B). Ninety Sprague Dawley rats were randomly divided into nine groups, consisting of five experimental groups and four control groups. In five experimental groups, Aβ1-42 was infused intracerebroventricularly and 3 days later, rats in each group were infused intracerebroventricularly with tubastatin A hydrochloride (TSA), the HDAC6-specific inhibitor (Aβ + TSA group), theophylline, the HDACs agonist (Aβ + Theo group), PF431396 (PF), the PTK2B inhibitor (Aβ + PF group), the combination of PF and theophylline (Aβ + PF + Theo group), and normal saline (Aβ + normal saline group), respectively.
