RNAseq in Alzheimer's Disease patients

ABSTRACT: Human brain samples from healthy and advanced Alzheimer's diseased patients were subjected to RNA-seq analysis to monitor RNA level changes during AD progression. Human brain samples were obtained from the Mount Sinai Brain Bank; RNA was Trizol extracted, ribominus selected and submitted for high-throughput sequencing.

Neuronal ELAV-like (nELAVL) RNA binding proteins have been linked to numerous neurological disorders. We performed crosslinking-immunoprecipitation and RNAseq on human brain, and identified nELAVL binding sites on 8681 transcripts. Using knockout mice and RNAi in human neuroblastoma cells, we showed that nELAVL intronic and 3' UTR binding regulates human RNA splicing and abundance. We validated hundreds of nELAVL targets among which were important neuronal and disease-associated transcripts, inc ...[more]

Molecular Signatures Underlying Selective Regional Vulnerability to Alzheimer's Disease

Project description:Alzheimer's disease (AD) is the most common form of dementia, characterized by progressive cognitive impairment and neurodegeneration as a result of abnormal neuronal loss. To elucidate the molecular systems associated with AD, we characterized the gene expression changes associated with multiple clinical and neuropathological traits in 1,053 postmortem brain samples across 19 brain regions from 125 persons dying with varying severities of dementia and variable AD-neuropathology severities. 125 human brains were accessed from the Mount Sinai/JJ Peters VA Medical Center Brain Bank (MSBB). This brain resource was assembled after applying stringent inclusion/exclusion criteria and represents the full spectrum of clinical and neuropathological disease severity in the absence of discernable non-AD neuropathology. RNA samples from 19 brain regions isolated from the 125 MSBB specimens were collected and profiled using Affymetrix Genechip microarrays. There were 50 to 60 subjects per brain region with varying degrees of AD pathological abnormalities.

Myeloid cell derived inducible nitric oxide synthase suppresses M1 macrophage polarization

Project description:Analysis of gene expression between WT and iNOS defecient M1 macrophage RNA microarray was performed using RNA isolated from M1 polarized macrophages from WT and iNOS deficient mice stimulated with LPS/IFNγ for 6 hours. Total RNA was extracted using a RNeasy plus kit (QIAGEN, Valencia, CA), and the array was performed on an Illumina MouseRef-8 v2.0 expression beadchip (Illumina, USA) by the Genomics Core Facility at the Mount Sinai School of Medicine.

Cerebellum Alzheimer's Disease

Project description:Ion channel splice array data from cerebellum brain tissue samples collected from Alzheimer's disease patients.

Expression data from skin fibroblasts derived from Setleis Syndrome patients and normal controls

Project description:Setleis Syndrome is a rare type of facial ectodermal dysplasia characterized by an aged leonine appearance with puckered skin about the eyes, absent eyelashes on both lids or multiple rows on the upper lids and none on the lower lids, eyebrows that slant sharply upward laterally, and a rubbery feel of the nose and chin. Some of the patients showed bilateral temporal marks superficially like forceps marks and like the lesions seen in focal facial dermal dysplasia. We have evidence that Setleis Syndrome is caused by nonsense mutations in the gene coding for the small bHLH transcription factor known as TWIST2 in Puerto Rican and Omani patients. We performed expression microarray analysis of RNA samples derived from skin fibroblasts grown from skin biopsies of Setleis Syndrome patients and normal controls in order to identify genes potentially involved in facial development and the pathogenesis of Setleis Syndrome. A total of 4 control and 4 Setleis Syndrome RNA samples were hybridized to U133 plus 2 Affymetrix 3'IVT arrays in the Mount Sinai School of Medicine Microarray Core Facility.
