OBJECTIVE: Constitutive overexpression of nucleophosmin/anaplastic lymphoma kinase (NPM/ALK) is a key oncogenic event in anaplastic large cell lymphomas (ALCL) that carry the t(2;5)(p23;q35) translocation. Global proteomic analysis of NPM/ALK-positive ALCL would improve understanding of the disease pathogenesis and yield new candidate targets for novel treatment and diagnostic strategies. MATERIALS AND METHODS: To comprehensively determine the inventory of proteins from NPM/ALK-positive ALCL SUDHL-1 cells, the membrane, cytoplasm, and nuclear subcellular fractions were resolved by one-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The MS spectra were interpreted using SEQUEST to search the electronic UniProt protein database, and analyzed by ProteinProphet and INTERACT. RESULTS: A total of 623 proteins consisting of 210 membrane, 229 cytoplasm, and 184 nuclear proteins were identified with a
