Cellular and interpatient heterogeneity and the involvement of different stem and progenitor compartments in leukemogenesis are challenges for the identification of common pathways contributing to the initiation and maintenance of acute myeloid leukemia (AML). Here we used a strategy of parallel transcriptional analysis of phenotypic long-term hematopoietic(More)
[URE3] is a prion of the yeast Ure2 protein. Hsp40 is a cochaperone that regulates Hsp70 chaperone activity. When overexpressed, the Hsp40 Ydj1p cures yeast of [URE3], but the Hsp40 Sis1p does not. On the basis of biochemical data Ydj1p has been proposed to cure [URE3] by binding soluble Ure2p and preventing it from joining prion aggregates. Here, we(More)
How hematopoietic stem cells (HSCs) coordinate the regulation of opposing cellular mechanisms such as self-renewal and differentiation commitment remains unclear. Here we identified the transcription factor and chromatin remodeler Satb1 as a critical regulator of HSC fate. HSCs lacking Satb1 had defective self-renewal, were less quiescent and showed(More)
1. In a study of 595 Little League pitchers, approximately 17% had a history of elbow symptoms: only 1% had elbow symptoms which had ever excluded them from pitching. There was no correlation between the presence of symptoms and years of pitching experience. 2. Some limitation of active extension of the elbow was seen in 12% of the pitchers; however, there(More)
Poor clinical outcome of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) has been attributed to failure of current chemotherapeutic regimens to target leukemic stem cells. We recently identified p21-activated kinase (PAK1) as a downstream effector molecule of H2.0-like homeobox (HLX), a gene functionally relevant for AML pathogenesis. In(More)
Despite the identification of several oncogenic driver mutations leading to constitutive JAK-STAT activation, the cellular and molecular biology of myeloproliferative neoplasms (MPN) remains incompletely understood. Recent discoveries have identified underlying disease-modifying molecular aberrations contributing to disease initiation and progression. Here,(More)
