Project description:In this exploratory study, we used laser microdissection to extract dopaminergic neurons from 10 human SNpc samples obtained at autopsy in Parkinson’s disease patients and control subjects. Extracted RNA and proteins were identified by RNA sequencing and nano-LC-MS/MS, respectively, and the differential expression between Parkinson’s disease and control group was assessed.
Project description: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.
Project description:Alzheimer’s disease (AD) is the most common neurodegenerative disorder being characterized by progressive impairment of memory and cognition, resulting in dementia. To investigate brain region vulnerability to AD and which pathways are altered in certain areas in AD, we performed proteomic profiling of human brain samples during AD progression in regions early (medial temporal lobe - MTL) and late affected (neocortex) by tau pathology. We employed a mass spectrometry-based approach to interrogate the human brain proteome during AD progression (B/B stages) in four distinct brain regions: entorhinal cortex (EC), parahippocampal cortex (PHC), temporal cortex (TC) and frontal cortex (FC). Importantly, we wanted to evaluate brain areas that are affected by tau pathology in different disease stages, in order to gain insights if there are common mechanisms or patterns shared between different brain regions during disease progression. A total of 103 samples were analyzed by nanoLC-MS/MS.
Project description:Human brain samples from control and advanced Alzheimer's Diseased subjects were subjected to HITS-CLIP to monitor nELAVL binding changes during AD progression Human brain samples were obtained from the Mount Sinai Brain Bank; samples were UV-irradiated and subjected to nELAVL HITS-CLIP (detailed desription in accompanying paper)
Project description:To demonstrate the utility of the newly developed dendron-coated phosphokinase antibody array(DPA) in which the antibodies are immobilized on a dendron-coated glass slide, the phosphorylation profiles of brain tissue samples obtained from Alzheimer's disease (AD) model mice were generated.
Project description:Ion channel splice array data from cerebellum 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:TRMT1L is a paralog of the tRNA m22G-methyltransferase TRMT1 and, similarly to TRMT1, it is involved in cognitive functioning. To functionally dissect the biological role of TRMT1L, here we have employed a combined strategy of LC-MS/MS and next-generation sequencing of both long and short RNAs, to compare the levels and locations of m2,2G in brain tissues from TRMT1L knock-out mice, relative to wild-type.
