Full text


Nucleophosmin (NPM1) is a ubiquitously expressed phosphoprotein that belongs to the nucleoplasmin family of chaperones. NPM1 is mainly localized in the nucleolus, and continuously shuttles between the nucleus and the cytoplasm. A high number of proteins have been described to interact with NPM1. NPM1 play a relevant role in diverse cellular functions, including, centrosome duplication, ribosome biogenesis, response to stress and ADN repair. Alterations of the NPM1 gene have been reported in anaplastic non Hodgkin’s lymphoma and acute myeloid leukemia (AML).
AML carrying nucleophosmin mutations (also referred to as NPMc+) displays distinct molecular and clinical–pathological features that led to its inclusion as a provisional entity in the 2008 WHO classification of myeloid neoplasms. Here, we discuss the role of NPM1 in myeloid malignancies focusing on i) involvement in AML pathogenesis; ii) diagnosis; iii) prognostic significance; iv) minimal residual disease monitoring and v) its potential as a target for tailored therapy.

Key words: Nucleophosmin, NPM1, myeloid malignancies.
