Myeloproliferative disorders and its associated mutations
Myeloproliferative Neoplasm (MPN) are a clonal disorder in hematopoietic stem cells (HSC). MPN is categorized to 8 subclasses, including chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocytopenia (ET), primary myelofibrosis (PMF), systematic mastositosis (SM), chronic eosinophilic leukemia (CEL), chronic neutrophilic leukemia (CNL), and unclassified myelofibrosis disorde...
متن کاملLnk constrains myeloproliferative diseases in mice.
Hematopoietic stem and progenitor cell (HSPC) expansion is regulated by intrinsic signaling pathways activated by cytokines. The intracellular kinase JAK2 plays an essential role in cytokine signaling, and activating mutations in JAK2 are found in a number of hematologic malignancies. We previously demonstrated that lymphocyte adaptor protein (Lnk, also known as Sh2b3) binds JAK2 and attenuates...
متن کاملAdaptor protein Lnk negatively regulates the mutant MPL, MPLW515L associated with myeloproliferative disorders.
Recently, activating myeloproliferative leukemia virus oncogene (MPL) mutations, MPLW515L/K, were described in myeloproliferative disorder (MPD) patients. MPLW515L leads to activation of downstream signaling pathways and cytokine-independent proliferation in hematopoietic cells. The adaptor protein Lnk is a negative regulator of several cytokine receptors, including MPL. We show that overexpres...
متن کاملLow Frequency of C-MPL Gene Mutations in Iranian Patients with Philadelphia-Negative Myeloproliferative Disorders
Background Myeloproliferative disorders are a group of diseases characterized by increased proliferation of myeloid lineage. In addition to JAK2V617F mutation, several mutations in the c-MPL gene were described in patients with Philadelphia-negative chronic myeloproliferative disorders that could be important in the pathogenesis of diseases. The aim of present study was to investigate the fre...
متن کاملMutations and promoter methylation status of NPM1 in myeloproliferative disorders.
We determined mutations and promoter methylation status of NPM1 using pyrosequencing in 199 samples of myeloid neoplasia including myeloproliferative disorders (MPD). The mutations were present in 4% of chronic myelomonocytic leukemia, but not in other MPD or myelodysplastic syndromes. Promoter methylation was rare, and was found in only three samples of MPD.
