Smad5 is dispensable for adult murine hematopoiesis.
Smad5 is known to transduce intracellular signals from bone morphogenetic proteins (BMPs), which belong to the transforming growth factor-beta (TGF-beta) superfamily and are involved in the regulation of hematopoiesis. Recent findings suggest that BMP4 stimulates proliferation of human primitive hematopoietic progenitors in vitro, while early progenitors from mice deficient in Smad5 display inc...
متن کاملMyelodysplastic Disorders, 5q-Syndrome
The myelodysplastic syndromes (MDSs) are characterized by ineffective erythropoie‐ sis and progressive cytopenia and ultimately affected patients develop acute myeloid leukemia (AML) or die from advanced bone marrow (BM) failure. Myelodysplastic syndrome (MDS) with isolated del (5q) is a common type of MDS with specific pathological and clinical manifestations including refractory anemia. It is...
متن کاملAurora kinase A is required for hematopoiesis but is dispensable for murine megakaryocyte endomitosis and differentiation.
Aurora kinase A (AURKA) is a therapeutic target in acute megakaryocytic leukemia. However, its requirement in normal hematopoiesis and megakaryocyte development has not been extensively characterized. Based on its role as a cell cycle regulator, we predicted that an Aurka deficiency would lead to severe abnormalities in all hematopoietic lineages. Here we reveal that loss of Aurka in hematopoie...
متن کاملSecretion of Wnts is dispensable for hematopoiesis.
In this issue of Blood, Kabiri and coworkers report the hematopoietic deletion of the endoplasmic reticulum–localized O-acyltransferase porcupine (PORCN), which is necessary for acylation of Wnts in the endoplasmic reticulum, enabling their secretion and binding to the frizzled receptors. Unexpectedly, the absence of secreted Wnt factors does not have major effects on steady-state in vivo hemat...
متن کاملVan den Berghe's 5q- syndrome and myelodysplastic syndrome with isolated del(5q)
The del(5q) cytogenetic abnormality was first described by Van den Berghe et al. in 1974. 1 The original manuscript described five patients with a macrocytic anemia, dyserythropoiesis with erythroid hypoplasia, normal to elevated platelet count, hypolobulated megakaryocytes and an interstitial deletion involving the long arm of chromosome 5. However, a deletion of chromosome 5q in myelodysplast...
