Alzheimer’s disease DNA (hydroxy)methylome in the brain and blood: OXT methylation as a preclinical marker.

ABSTRACT: The present study investigated the DNA methylome and hydroxymethylome, as well as unmodified cytosine in relation to Alzheimer’s disease (AD). We identified epigenetic differences between AD patients and age-matched controls in the middle temporal gyrus, in genomic regions associated with genes such as OXT, ACSL1, RHBDF2, C3, and MIR9-3HG. Interestingly, we found that OXT methylation in the blood of aged, non-demented individuals is also associated with conversion to AD dementia. The current GEO submission concerns the middle temporal gyrus Illumina HumanHT-12 V4.0 expression dataset of this study that was used to look at the correlation between the detected epigenetic changes and gene expression.

Non-demented individuals with intermediate Alzheimer's neuropathologies - neuronal expression (6 regions)

Project description:Layer II stellate neurons (entorhinal cortex) and layer III cortical neurons (hippocampus CA1, middle temporal gyrus, posterior cingulate, superior frontal gyrus, primary visual cortex) were gene expression profiled. Brain regions are from non-demented individuals with intermediate Alzheimer's disease neuropathologies Keywords: neuronal gene expression profiling

Genome-wide DNA methylation profiling in the superior temporal gyrus reveals epigenetic signatures associated with Alzheimer's disease

Project description:Recent work has identified roles for environmental, genetic and epigenetic factors in AD risk. Motivated by suspected roles for epigenetic modifications in AD, we performed a genome-wide screen of DNA methylation using the Illumina Infinium HumanMethylation450 array platform on bulk tissue samples from the superior temporal gyrus (STG) of AD cases and non-demented controls. We paired a sliding window approach with linear models that account for age, gender, ethnicity, and estimated cellular proportions (neuronal vs. glial), to characterize AD-associated differentially methylated regions (DMRs).

Project description:Alternative polyadenylation (APA) contributes to post-transcriptional regulation, but its role in Alzheimer’s disease (AD) is largely unknown. Using high-resolution SQUARE multiple 3’ primer-based sequencing, we discovered massive APA differences in temporal gyrus tissues from demented AD patients compared to either healthy controls or non-demented donors with AD neuropathology (NDWP). Advanced statistics, microfluidics RT-PCR and protein measurements validated known and novel APA-modified 3’-intact transcripts. Moreover, APA modifications, more than total transcript counts, distinguished AD patients from both controls and NDWP donors and identified cell type-characteristic, cognition-associated and neuropathology-related changes. AD-enhanced APA variants included known therapeutic targets of brain, vascular and autoimmune disorders, predicting co-involvement of these target genes in AD progression; AD/NDWP increases in 3’-intact proteinopathy-related hnRNP mRNAs were inversely associated with protein decreases, whereas NDWP-potentiated cognition was accompanied by distinct ATP and mitochondrial variants. APA variations thus provide a novel resource of unique value for both basic and translational neuroscience researchers.

Simultaneous sequencing of coding and non-coding RNA from patients with Alzheimer's disease

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.

Dementia Comparison: VaD vs. AD vs. Controls

Project description:Gene expression profiling was performed on frontal and temporal cortex from vascular dementia (VaD), Alzheimer's disease (AD), and non-demented controls (Control) obtained from the University of Michigan Brain Bank. Controls and AD cases had no infarcts in the autopsied hemisphere. Vascular dementia cases had low Braak staging.

Human temporal neocortex brain LC-MS

Project description:We used label-free shotgun mass spectrometry to analyze temporal neocortex samples from AD brain, other neurological disorders and non-demented controls, in order to identify additional proteins thatare altered in AD. The mass spectrometry results were then verified by antibody suspension bead arrays.

Transcriptome changes in the Alzheimer's middle temporal gyrus: importance of RNA metabolism and mitochondria-associated membrane (MAM) genes

Project description:We used Illumina Human HT-12 v4 arrays to compare RNA expression of middle temporal gyrus (MTG; BA21) in Alzheimer’s Disease (AD = 97) and non-demented controls (ND = 98). A total of 938 transcripts were highly differentially expressed (adj p < 0.01; log2 Fold Change (FC) ≥ |0.500|, with 411 overexpressed and 527 underexpressed in AD. Our results correlated with expression profiling in neurons from AD and ND obtained by Laser Capture Microscopy in MTG from an independent dataset (log2 FC correlation: r = 0.504; p = 2.2e-16). Additionally selected effects were validated by qPCR. ANOVA analysis yielded no difference between genders in response to AD, but some gender specific genes were detected (e.g: IL8 and AGRN in males, and HSPH1 and GRM1 in females). Several transcripts were associated with Braak Staging (e.g AEBP1 and DNALI1), ante-mortem MMSE (e.g. AEBP1 and GFAP) and Tangle density (eg. RNU1G2, and DNALI1). At the pathway level we detected enrichment of Synaptic Vesicle Processes and GABAergic transmission genes. Finally, applying the Weighted Correlation Network Analysis (WGCNA) we identified 4 expression modules enriched for neuronal and synaptic genes, mitochondria-associated membrane (MAM), chemical stimulus and olfactory receptor and non-coding RNA metabolism genes. Our results represent an extensive description of MTG mRNA profiling in a large sample of AD and ND. These data provide a list of genes associated with AD, and correlated to neurofibrillary tangles density. In addition, these data emphasize the importance of mitochondrial membranes and transcripts related to olfactory receptors in AD.
