Project description:Ion channel splice array data from cerebellum brain tissue samples collected from Alzheimer's disease patients. Temporal cortex (Alzheimer's disease affected brain tissue structure) and cerebellum (Alzheimer's disease unaffected brain tissue structure) samples from control subjects were compared to temporal cortex and cerebellum of patients with Alzheimer's disease.

Project description:The project aims to find diagnostic biomarkers for Alzheimer's disease in plasma. We applied discovery based proteomics was used to detect changes in proteins due to Alzheimer's disease using plasma samples collected from four study groups (African American Alzheimer's disease & cognitively normal, non-Hispanic-White Alzheimer's disease & cognitively normal). The data emphesizes the need for inclusion in Alzheimer's disease research.

Project description:FK506 binding protein 51kDa (FKBP51/FKBP5) is part of a mature heat shock protein 90kDa (Hsp90) chaperone complex that preserves tau. Microarray analysis of human brains reveal that FKBP51 gene expression selectively increased with age and Alzheimer's disease, which correlated with demethylation of the regulatory regions in the FKBP5 gene. Moreover, FKBP51 levels significantly correlated with Braak pathological staging. In addition, we show that in brains devoid of FKBP51, tau levels are reduced. Recombinant FKBP51 and Hsp90 synergize to block tau clearance through the proteasome and produce T22-positive tau oligomers. Overexpression of FKBP51 in a tau transgenic mouse model revealed that FKBP51 preserved tau species, including phosphorylated and oligomeric tau that have been linked to Alzheimer's disease pathogenesis. FKBP51 blocked amyloid formation and decreased tangle load in the brain. These alterations in tau turnover and aggregate structure culminated in enhanced neurotoxicity. We propose a model where age-associated increases in FKBP51 levels can out-compete the association of other pro-degradation Hsp90 co-chaperones, resulting in neurotoxic tau accumulation. Thus, strategies aimed at attenuating FKBP51 levels or its interaction with Hsp90 could be therapeutically relevant for Alzheimer's disease and other tauopathies. These AD cases were processed simultaneously with the control cases (young and aged) included in GSE11882 Postmortem brain tissue was collected from ADRC brain banks. Cases were preferentially selected where 3 or more brain regions were available
