Project description:Human post-mortem brain samples (middle temporal gyrus) from Alzheimer's disease (AD) and control individuals were processed for simultaneous coding and non-coding RNA-Seq analysis using a novel RNA-Seq protocol. These data were then analyzed for differential expression.
Project description:Epigenome Analysis of Post-Mortem Human Temporal Pole Brain Tissue For more information, please refer to DOI: 10.3233/JAD-141989 Temporal Pole regions from 24 age-matched causcasian males: 8 samples which died of normal causes, 8 samples with Alzheimer's disease (stage 3/4) and 8 samples with dementia with lewy bodies
Project description:Short RNA sequencing of post-mortem human hippocampi from the Calgary Brain Bank. The dataset includes patients with Alzheimer's disease (AD) and healthy control individuals (Ctrl).
Project description:Protein from astrocytes (glial fibrillary acidic protein-positive cells), neurons (beta-III tubulin-positive cells), and unsorted (cell suspension without any enrichment based on astrocyte or neuron markers) from human, post-mortem Alzheimer's disease (AD) and aged-matched non-symptomatic (NS) prefrontal cortex brain samples.
Project description:Human tauopathies including Alzheimer's disease are characterized by alterations in the post-translational modification (PTM) pattern of Tau, leading to the formation of insoluble aggregates, neuronal dysfunction and degeneration. We immunoprecipitated Tau from post-mortem brain tissue of early stage Alzheimer's disease patients and age-matched controls, and analyzed PTMs on this soluble pool of Tau protein. In addition to known serine, threonine and tyrosine phosphorylation events, we identified a number of previously unknown monomethylation events on lysines in both control and Alzheimer's patient tissues.

Project description:We quantified genome-wide levels of H3K27ac in post-mortem entorhinal cortex tissue samples, identifying widespread Alzheimer's disease (AD)-associated acetylomic variation. Differentially acetylated peaks were identified in the vicinity genes implicated in both tau and amyloid neuropathology (MAPT, APP, PSEN1, PSEN2), as well as genomic regions containing variants associated with sporadic late-onset AD (CR1, TOMM40). Both MAPT and PSEN2 are characterized by an extended hyperacetylated region upstream of the TSS mapping to enhancers in the brain. We show that genes annotated to AD-associated hyper- and hypoacetylated peaks are enriched for brain- and neuropathology-related functions.
