Hyperactivation of the transcription factor Stat5 leads to various leukemias. Stat5 activity is regulated by the protein phosphatase SHP-1 in a phospholipase C (PLC)-β3-dependent manner. Thus, PLC-β3-deficient mice develop myeloproliferative neoplasm, like Lyn (Src family kinase)- deficient mice. Here we show that Lyn/PLC-β3 doubly deficient lyn(-/-);PLC-β3(-/-) mice develop a Stat5-dependent, ...
Success of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia (CML) has given patients hope for a long disease-free-survival. A longer survival raises the question of late effects, including development of another malignancy. Records of 1445 patients with CML/ myeloproliferative neoplasm or other hematologic malignancies treated with TKIs were reviewed to investigate frequency and ch...
PURPOSE The myeloproliferative neoplasm myelofibrosis is characterized by frequent deregulation of Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling, and JAK inhibitors were shown to reduce splenomegaly and ameliorate disease-related symptoms. However, the mutant clone and bone marrow fibrosis persist in the majority of patients. Using preclinical models, we e...
Hyperactivation of the transcription factor Stat5 leads to various leukemias. Stat5 activity is regulated by the protein phosphatase SHP-1 in a phospholipase C (PLC)– 3-dependent manner. Thus, PLC3–deficient mice develop myeloproliferative neoplasm, like Lyn (Src family kinase)– deficient mice. Here we show that Lyn/ PLC3 doubly deficient lyn / ;PLC3 / mice develop a Stat5-dependent, fatal myel...
Success of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia (CML) has given patients hope for a long disease-free-survival. A longer survival raises the question of late effects, including development of another malignancy. Records of 1445 patients with CML/myeloproliferative neoplasm or other hematologic malignancies treated with TKIs were reviewed to investigate frequency and cha...
TET2 converts 5-methylcytosine to 5-hydroxymethylcytosine (5-hmC) in DNA and is frequently mutated in myeloid malignancies, including myeloproliferative neoplasms. Here we show that the level of 5-hmC is decreased in granulocyte DNA from myeloproliferative neoplasm patients with TET2 mutations compared with granulocyte DNA from healthy patients. Inhibition of TET2 by RNA interference decreases ...
According to the World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues, myeloproliferative neoplasms (MPN) include chronic myeloid leukemia and the so-called Philadelphia-negative myeloproliferative neoplasms, i.e. essential thrombocythemia, polycythemia vera and primary myelofibrosis. Myeloproliferative features are also observed in a group of disorders...
"Refractory anemia with ring sideroblasts and thrombocytosis" (RARS-T) is a rare disease, a provisional entity, with a controversial status in the 2008 revised WHO classification. Even at present time, RARS-T is a matter of debate whether it is a distinct clinicopathological entity or more likely a constellation of clinical and pathological features of two well-defined myeloid neoplasms, myelod...
Centriolar satellites are proteinaceous granules that are often clustered around the centrosome. Although centriolar satellites have been implicated in protein trafficking in relation to the centrosome and cilium, the details of their function and composition remain unknown. FOP (FGFR1 Oncogene Partner) is a known centrosome protein with homology to the centriolar satellite proteins FOR20 and O...
