125I-Porcine brain natriuretic peptide (125I-pBNP) bound to mouse astrocytes in primary culture in a time-dependent manner (t1/2 = 4.5 min), similar to 125I-human atrial natriuretic peptide (125I-hANP) (t1/2 = 5 min). Binding was saturable and reached equilibrium after 90 min at 22 degrees C for both radioligands. Scatchard analysis suggested a single class(More)
Meis1 is recognized as an important transcriptional regulator in hematopoietic development and is strongly implicated in the pathogenesis of leukemia, both as a Hox transcription factor co-factor and independently. Despite the emerging recognition of Meis1's importance in the context of both normal and leukemic hematopoiesis, there is not yet a full(More)
Hematopoiesis depends on a tightly controlled balance of self-renewal, proliferation, cell death and differentiation. Although the disturbance of this equilibrium creates a predisposition to leukemogenesis, targeted manipulation or modulation can in turn lead to therapeutic advances. In addition to chromosomal aberrations and frequently mutated genes such(More)
Extensive molecular profiling of leukemias and preleukemic diseases has revealed that distinct clinical entities, like acute myeloid (AML) and T-lymphoblastic leukemia (T-ALL), share similar pathogenetic mutations. It is not well understood how the cell of origin, accompanying mutations, extracellular signals or structural differences in a mutated gene(More)
Atrial natriuretic peptide (ANP), first isolated from rat atrial cardiocytes, is a potent natriuretic, diuretic and vasorelaxant hormone when given intravenously. In keeping with increasing evidence that many bioactive peptides that were first discovered in peripheral organs, are often present in the central nervous system, ANP and its binding sites have(More)
