Project description:Ion channel splice array data from temporal cortex 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:There is accumulating evidence that amyloid beta and tau proteins may act synergistically to cause synapse and neural circuit degeneration in Alzheimer’s disease. In order to study this, we designed a new mouse model which lacks endogenous mouse tau, but expresses both the APP/PS1 transgene, which causes well-characterised plaque-associated synapse loss, and also reversibly expresses wild-type human tau (which can be suppressed with doxycycline). We examined the transcriptional changes in the frontal cortex of this mouse model, along with behaviour, pathology, synaptic plasticity, synapse degeneration and accumulation of amyloid beta and tau at synapses, and compared with littermate control genotypes: those lacking endogenous mouse tau, those lacking endogenous mouse tau but expressing the APP/PS1 transgene only, and those lacking endogenous mouse tau but reversibly expressing wild-type human tau only.

Project description:This dataset contains microarray data from normal controls (aged 20-99 yrs) and Alzheimer's disease cases, from 4 brain regions: hippocampus, entorhinal cortex, superior frontal cortex, post-central gyrus. Changes in expression of synaptic and immune related genes were analyzed, investigating age-related changes and AD-related changes, and region-specific patterns of change. These AD cases were processed simultaneously with the control cases (young and aged) included in GSE11882 (GSE11882 dataset contains data exclusively from normal control brains).
