(Submitter supplied) The WT and Tg(RE:HSE:EGFP) F2 generation embryos were heated shocked at 38°C for 1 hour at 16 hpf, then raised to 3 dpf. Total RNAs were isolated with Trizol (Invitrogen). The samples were processed and subsequently analyzed in triplicate on Zebrafish Oligo Microarrays (Agilent Technologies Italia, Italy) which contain 43,554 sets of probes. The microarrays were scanned in an Agilent DNA Microarray Scanner and the images were processed using Feature Extraction software to identify changes of gene expression signatures in Tg(RE:HSE:EGFP) zebrafish embryos.

(Submitter supplied) Erg is an ETS family transcription factor frequently overexpressed in human leukemias and has been implicated as a key regulator of hematopoietic stem cells (HSCs). However how Erg controls normal hematopoiesis, particularly at the stem cell level, remains poorly understood. Using homologous recombination, we generated an Erg knockdown allele (Ergkd) in which Erg expression can be restored upon Cre-mediated excision of a Stopper cassette. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) and lymphoid-primed multi-potential progenitors (LMPPs) are able to initiate both lymphoid and myeloid differentiation. We show here that the transcriptional repressor Gfi1 (growth factor independence 1) implements a specific gene expression program in HSCs and LMPPs that is critical for their survival and lymphoid differentiation potential. We present evidence that Gfi1 is required to maintain expression of genes involved in lymphoid development such as Flt-3, IL7R, Ebf1, Rag1, CCR9 and Notch1 and controls myeloid lineage commitment by regulating expression of genes such as Hoxa9 or M-CSFR. more...

Analysis of Lin-Sca1+ckit+Flt3- (LSKFlt3-) hematopoietic stem cells (HSC) depleted of growth factor independence 1 (Gfi1). Transcriptional repressor Gfi1 restricts HSC proliferation and is essential to self-renewal. Results provide insight into molecular mechanisms underlying Gfi1 effects in HSCs.

(Submitter supplied) Regulation of quiescence is critical for the maintenance of adult hematopoietic stem cells (HSCs). Previous studies by gene disruption during mouse embryonic development have shown that transcription factor gene Prdm16 is important for the generation/maintenance of fetal liver HSCs; however, the underlying mechanisms and the function of Prdm16 in adult HSCs remain unclear. To investigate the role of Prdm16 in adult HSCs, we generated a novel conditional knockout mouse model and deleted Prdm16 in adult mouse hematopoietic system using the interferon inducible Mx1-Cre. more...

(Submitter supplied) MicroRNAs are critical post-transcriptional regulators of hematopoietic cell-fate decisions, though little remains known about their role in aging hematopoietic stem cells (HSCs). The microRNA-212/132 cluster (miR-212/132) is enriched in HSCs and is up-regulated during hematopoietic aging. Both over-expression and deletion of microRNAs in this cluster leads to inappropriate hematopoiesis with age. Enforced expression of miR-132 in the bone marrow compartment of mice led to rapid HSC cycling followed by their depletion. more...

(Submitter supplied) Obesity is a chronic organismal stress that disrupts multiple systemic and tissue-specific functions. Here, we describe the effects of established obesity on the activity of the hematopoietic stem cell (HSC) compartment. We show that obesity promotes the selection of a quiescent HSC subset primed for activation, leading to aberrant hematopoietic stress responses. We establish that the transcription factor Gfi1 is a key regulator of the HSC fate in obesity as its increased expression in obesity induces their abnormal activity. more...

(Submitter supplied) B cell CLL/lymphoma 11A (BCL11A) is a transcription factor and regulator of hemoglobin switching that has emerged as a promising therapeutic target for sickle cell disease and thalassemia. In the hematopoietic system, BCL11A is required for B lymphopoiesis, yet its role in other hematopoietic cells, especially hematopoietic stem cells (HSCs) remains elusive. The extensive expression of BCL11A in hematopoiesis implicates context-dependent roles, highlighting the importance of fully characterizing its function as part of ongoing efforts for stem cell therapy and regenerative medicine. more...

(Submitter supplied) ARID1A is a component of the mammalian SWI/SNF complex involved in chromatin remodeling. A functional SWI/SNF complex is required for diverse physiological processes including hematopoiesis, however, the precise role played by ARID1A in hematopoietic development is unclear. Here we utilize hematopoietic cell-specific deletion of Arid1a in mice to uncover its role during adult hematopoiesis. We demonstrate that ARID1A is essential for maintaining the frequency and function of hematopoietic stem cells and its loss impaired the differentiation of both myeloid and lymphoid lineages. more...
