(Submitter supplied) Analysis of HSCs from control and c-myc N-myc deficient long-term hematopoietic stem cells. HSCs lacking both c-myc and N-myc display increased apoptosis rates. Data provide insight into the molecular changes occuring upon complete loss of Myc activity, clarifying the resulting apoptotic mechanism and the role of Myc family proteins in HSCs and commited progenitors.

(Submitter supplied) We identified the ubiquitin ligase Huwe1 as a crucial regulator of hematopoietic stem cell (HSC) functions. We generated Huwe1 conditional knock-out mice and discovered that the loss of this ligase causes an increased proliferation and stem cell exhaustion, together with a decreased lymphoid specification in vivo. We observed that the ubiquitin ligase Huwe1 is controlling the expression of N-myc at the level of the most immature stem and progenitor hematopoietic populations, mediating the described effects.

(Submitter supplied) As the major histone H3K4 methyltransferases in mammals, the Set1/Mll complexes play important roles in animal development and are increasingly associated with diseases including hematological malignancies. The role of H3K4 methylation activity of these complexes, however, remains elusive in fate determination of hematopoietic stem and progenitor cells (HSCs and HPCs). Here we address this question by generating a conditional knockout mouse for Dpy30, which is a common core subunit of all Set1/Mll complexes and facilitates genome-wide H3K4 methylation in cells. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) maintain balanced self-renewal and differentiation according to physiological demands, but how different facets of these functions are precisely regulated is not fully understood. N6-methyladenosine (m6A) mRNA methylation has emerged as an important mode of epitranscriptional gene expression regulation affecting many biological processes. We show that deleting the m6A methyltransferase, Mettl3, from the adult hematopoietic system led to an accumulation of HSCs in the bone marrow and marked reduction of HSC reconstitution potential due to a blockage of HSC differentiation. more...

(Submitter supplied) To ensure the rapid response to stimuli, some HSCs are specifically prepared (primed) for tasks involving activation and reconstitution. However, the key factors that regulate the primed state of HSCs are largely unknown. Here we report that Med23 controls the formation of myeloid-primed HSCs. Ablation of Med23 in hematopoietic system leads to lymphocytopenia. Moreover, Med23-deficient HSCs undergo myeloid-biased differentiation and lose the self-renewal capacity. more...

(Submitter supplied) In response to myeloablative stresses, HSCs are rapidly activated to replenish myeloid progenitors, while maintaining full potential of self-renewal to ensure life-long hematopoiesis. However, the key factors that orchestrate HSC activities during physiological stresses remain largely unknown. Here we report that Med23 controls the myeloid potential of activated HSCs.

(Submitter supplied) In blood, the transcription factor C/EBPa is essential for myeloid differentiation and has been implicated in regulating self-renewal of fetal liver hematopoietic stem cells (HSCs). However, its function in adult HSCs is unknown. Here, using an inducible knockout model, we found that C/EBPa deficient adult HSCs underwent a pronounced expansion with enhanced proliferation, characteristics resembling fetal liver HSCs. more...

(Submitter supplied) Hematopoiesis is a series of lineage differentiation programs initiated from hematopoietic stem cells (HSCs) in the bone marrow (BM). To maintain lifelong hematopoiesis, the pool of HSCs is precisely maintained by diverse molecular mechanisms. CCCTC-binding factor (CTCF) is a DNA-binding zinc-finger protein which regulates its target gene expression by organizing higher order chromatin structures. Currently, the role for CTCF in controlling HSC homeostasis is unknown. more...

(Submitter supplied) SET domain containing 2 (Setd2), encoding a histone methyltransferase, is associated with many hematopoietic diseases when mutated. By generating a novel exon 6 conditional knockout mouse model, we described an essential role of Setd2 in maintaining the adult hematopoietic stem cells. Loss of Setd2 results in leukopenia, anemia, and increased platelet accompanied with hypocellularity, erythroid dysplasia, and mild fibrosis in bone marrow. more...
