The nucleophosmin (NPM1) activates cancer development and progression in many malignant tumors. However, the regulatory role and underlying mechanisms of NPM1 in pancreatic cancer are unknown. In this study, we showed that NPM1 was up-regulated in PDAC, which indicated a poor prognosis. We also identified NPM1 could stimulate aerobic glycolysis and repress fructose-1, 6-bisphosphatase 1 (FBP1) ...
Somatic mutations in isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) were recently demonstrated in acute myeloid leukemia (AML), but their prevalence and prognostic impact remain to be explored in large extensively characterized AML series, and also in various other hematologic malignancies. Here, we demonstrate in 893 newly diagnosed cases of AML mutations in the IDH1 (6%) and IDH2 (11%) gene...
زمینه و هدف : لوسمی حاد میلوییدی یک بیماری بدخیم بافت خونساز است که با تجمع سلول های غیرطبیعی و تمایزنیافته به نام سلول های بلاستیک میلوئیدی در مغز استخوان و اختلال تولید سلول های طبیعی خونی مشخص می شود. این مطالعه به منظور تعیین جهش ژنی flt3 و npm1 و یافته های آزمایشگاهی در بیماران مبتلا به لوسمی حاد میلوییدی در شمال غرب ایران انجام شد. روش بررسی : این مطالعه توصیفی - تحلیلی روی 40 بیمار (24 م...
BACKGROUND DNMT3A mutations represent one of the most frequent gene alterations detectable in acute myeloid leukemia (AML) with normal karyotype. Although various recurrent somatic mutations of DNMT3A have been described, the most common mutation is located at R882 in the methyltransferase domain of the gene. Because of their prognostic significance and high stability during disease evolution, ...

BACKGROUND Despite the molecular heterogeneity of standard-risk acute myeloid leukemia (AML), treatment decisions are based on a limited number of molecular genetic markers and morphology-based assessment of remission. Sensitive detection of a leukemia-specific marker (e.g., a mutation in the gene encoding nucleophosmin [NPM1]) could improve prognostication by identifying submicroscopic disease...
Mutations in the nucleophosmin gene (NPM1(mut)) are one of the most frequent molecular alterations in acute myeloid leukemia (AML), and immune responses may contribute to the favorable prognosis of AML patients with NPM1(mut). In the present study, we were able to demonstrate both CD4(+) and CD8(+) T-cell responses against NPM1(mut). Ten peptides derived from wild-type NPM1 and NPM1(mut) were s...
tions. It is tempting to speculate that these cases are linked by a common underlying mutation that predisposes to DNA replication errors. What “unlinks” WT1 and NPM1 are their different prognostic influences. This study makes it clear that WT1 mutations are associated with unfavorable outcomes in childhood AML, as shown in the figure. Another important difference between WT1 and NPM1 mutations...
We investigated the NPM1 mutation status or subcellular expression of NPM protein (nuclear vs. aberrant cytoplasmic) at diagnosis and relapse in 125 patients with acute myeloid leukemia from Italy and Germany. All 52 patients with acute myeloidleukemia carrying at diagnosis mutated or cytoplasmic NPM (NPMc(+) acute myeloid leukemia) retained this feature at relapse. Notably, cytoplasmic mutated...
During polyadenylation, the multi-functional protein nucleophosmin (NPM1) is deposited onto all cellular mRNAs analysed to date. Premature termination of poly(A) tail synthesis in the presence of cordycepin abrogates deposition of the protein onto the mRNA, indicating natural termination of poly(A) addition is required for NPM1 binding. NPM1 appears to be a bona fide member of the complex invol...
