Spatial centrosome proteome of human neural cells uncovers novel interactors and disease hubs

Version 1

This project serves as a centralized repository for omics datasets published by research groups within the SyNergy Cluster. It encompasses investigations such as proteomics and transcriptomics, which are further divided into individual studies led by SyNergy members. Each study is linked to relevant publications, assays and data files (with links to external repositories).

The centrosome provides an intracellular anchor for the cytoskeleton, regulating cell division, cell migration, and cilia formation. We used spatial proteomics to elucidate protein interaction networks at the centrosome of human induced pluripotent stem cell-derived neural stem cells (NSCs) and neurons. Centrosome-associated proteins were largely cell type-specific, with protein hubs involved in RNA dynamics. Analysis of neurodevelopmental disease cohorts identified a significant overrepresentation ...

For proteomic analysis, iPSC-derived neural stem cells at day 15 of culture were treated with 3.3 uM Nocodazole (Sigma) or same volume of DMSO (control) before being washed with ice-cold PBS, scrapped and centrifuged for 10 min at 300 g before lysis in Buffer A, containing 50 mM Tris-HCL (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1% Triton-X100, 0.1% SDS, protease inhibitor (Pierce), at a volume twice that of the pellet. For neurons, day 40 of cultures treated only with DMSO were used. Samples ...
