title: Synthesis, chaperoning, and metabolism of proteins are regulated by NT-3/TrkC signaling in the medulloblastoma cell line DAOY.
abstract: The human medulloblastoma cell line DAOY was transfected with Tropomyosin receptor kinase (TrkC), a marker for good prognostic outcome. Following TrkC-activation by its ligand neurotrophin-3, protein extracts from DAOY cells were run on 2DE with subsequent MALDI-TOF-TOF analysis and quantification in order to detect downstream effectors. Protein levels of translational, splicing, processing, chaperone, protein handling, and metabolism machineries were shown to depend on neurotrophin-3-induced TrkC activation probably representing pharmacological targets.
