Mutations in the NPM1 gene represent the most frequent genetic alterations in patients with acute myeloid leukemia (AML) and are associated with a favorable outcome. In 690 normal karyotype (NK) AML patients the complete remission rates (CRs) and the percentage of patients with adequate in vivo blast cell reduction 1 week after the end of the first induction cycle were significantly higher in N...

AIM OF THE STUDY Mutant NPM1 and CEBPA have been reported in patients with acute myeloid leukaemia (AML) and intermediate cytogenetic risk, and they appear to be associated with characteristic demographic and laboratory data, as well as clinical outcome. The objective of the study was to assess the clinical relevance of NPM1 and CEBPA mutations in AML. MATERIAL AND METHODS This retrospective ...
NPM1 mutations were investigated in 400 Southeast Asian leukemia patients and were detectable in 105 cases (26.25%) of acute myeloid leukemia but in no cases of acute lymphoid leukemia or chronic myeloid leukemia. Eight novel and 5 known mutations were identified. All predicted novel proteins shared the last five amino acids VSLRK with the similar gain of nuclear exporting signal motif as known...
Porcine epidemic diarrhea virus (PEDV) replicates in the cytoplasm of infected cells, but its nucleocapsid (N) protein localizes specifically to the nucleolus. The mechanism of nuclear translocation, and whether N protein associates with particular nucleolar components, is unknown. In this study, we confirm that a nucleolar phosphoprotein nucleophosmin (NPM1) interacts and co-localizes with the...
Somatic cell nuclear transfers and the generation of induced pluripotent stem cells provide potential routes towards non-immunogenic cell replacement therapies. Translationally controlled tumor protein (Tpt1) was recently suggested to regulate cellular pluripotency. Here we explore functions of Tpt1 in mouse embryonic stem (ES) cells. We find that Tpt1 is present in the nucleus and cytoplasm of...
Nucleophosmin (NPM1) is an abundant nucleolar protein implicated in ribosome maturation and export, centrosome duplication and response to stress stimuli. NPM1 is the most frequently mutated gene in acute myeloid leukemia. Mutations at the C-terminal domain led to variant proteins that aberrantly and stably translocate to the cytoplasm. We have previously shown that NPM1 C-terminal domain binds...
Nucleophosmin (NPM1, also known as B23, numatrin or NO38) is a pentameric RNA-binding protein with RNA and protein chaperon functions. NPM1 has increasingly emerged as a potential cellular factor that directly associates with viral proteins; however, the significance of these interactions in each case is still not clear. In this study, we have investigated the physical interaction of NPM1 with ...
OBJECTIVE In this study, we evaluated the frequency of FMS-like tyrosine kinase 3 (FLT3-ITD and FLT3-TKD) and nucleophosmin (NPM1) mutations in Iranian patients with cytogenetically normal acute myeloid leukemia (CN-AML). The clinical and laboratory characteristics were compared between wild-type and mutant cases. MATERIALS AND METHODS Seventy newly diagnosed de novo AML patients were recruit...
Nucleophosmin (NPM1) is a nucleocytoplasmic shuttling phosphoprotein, mainly localized at nucleoli, that plays a key role in ribogenesis, centrosome duplication, and response to stress stimuli. Mutations at the C-terminal domain of NPM1 are the most frequent genetic lesion in acute myeloid leukemia and cause the aberrant and stable translocation of the protein in the cytoplasm. The NPM1 C-termi...
