Project description:We report the application of high-throughput RNA sequencing to the human prefrontal cortex. The brain dataset was obtained by sequencing total RNAs extracted from the dorsolateral prefrontal cortex of five deceased human patients with no apparent pathology, followed by depletion of ribosomal RNA to obtain all non-rRNA coding and non-coding RNAs in the human brain transcriptome. Five samples were sequenced, four coming from frozen brain tissue (frontal cortex) of deceased female human patients with no remarkable pathology, and one from a male patient with no remarkable pathology.
Project description:FTLD-U is the most common pathological correlate of the neurodegenerative dementia frontotemporal dementia; We used microarrays to perform global expression profiling of FTLD-U brain samples Experiment Overall Design: Postmortem brain samples were isolated from normal controls, FTLD-U patients with progranulin gene mutations (progranulin) and FTLD-U patients without progranulin gene mutations (sporadic). Regional dissections were carried out from frontal cortex, hippocampus, and cerebellum.
Project description:We performed the Chip-seq to brain tissues from prefrontal cortex region in AD Postmortem samples and non-dementia control postmortem samples.

Project description:Understanding the molecular mechanisms underlying frontotemporal dementia (FTD) is essential for the development of successful therapies. Systematic studies on human post-mortem brain tissue of patients with genetic subtypes of FTD are currently lacking. The Risk and Modyfing Factors of Frontotemporal Dementia (RiMod-FTD) consortium therefore has generated multi-omics datasets for genetic subtypes of FTD to identify common and distinct molecular mechanisms disturbed in disease. This experiment contains data from RNA-sequencing of human post-mortem brain tissue of the frontal lobe from patients with FTD caused by mutations in GRN, MAPT or C9orf72 and healthy controls.

Project description:Spontaneous intracerebral hemorrhage (ICH) represents about 15% of all strokes and is associated with high mortality rates. Our aim was to identify the gene expression changes and biological pathways altered in the brain following ICH. Twelve brain samples were obtained from four deceased patients who suffered an ICH including perihematomal tissue (PH) and the corresponding contralateral white (CW) and grey (CG) matter. Brain samples from 4 deceased patients who had a supratentorial intracerebral hemorrhage within the previous 4 days were included in the microarray study. This study group included 2 women and 2 men with a median age of 79 (68-92). On autopsy and during macroscopic exam, perihematomal areas suspected to present edema were identified by an experienced neuropathologist using last available neuroradiology images. Samples from perihematomal areas (PH), contralateral grey matter (CG) and contralateral white matter (CW) were obtained within the first 5 h after death and snap frozen in liquid nitrogen and stored at -80ºC until RNA isolation.
Project description:In this study, we performed the first genome-wide expression profiling of post-mortem brains of a cohort of patients deceased from SVD and compared them to age-matched normal controls. Normal-appearing frontal temporal and occipital cortical and subcortical brain samples were dissected at autopsy from 5 patients diagnosed with pure SVD and 5 control patients without neurological disease and immediately frozen.
