(Submitter supplied) To investigate the molecular basis for the reversible suppression of HSCs by leukemia, we sorted the CD45.1+LKS+ population from control or leukemic mice at day 7 and day 14 for gene expression profiling analysis.

(Submitter supplied) We have developed a new conditional transgenic mouse showing that MLL-ENL, at an endogenous-like expression level, induces leukemic transformation selectively in LT-HSCs. To investigate the molecular mechanism of leukemic transformation in LT-HSCs conditionally expressing MLL-ENL, we preliminarily performed comprehensive gene expression profiling of CreER-transduced LT-HSCs and ST-HSCs using cDNA microarray analysis.

(Submitter supplied) Background: MLL (KMT2A)-EB1 (MAPRE1) fusion was identified in a patient with de novo pro-B acute lymphoblastic leukemia. To investigate the leukemogenesis of MLL-EB1 fusion, a retroviral transduction of MLL-EB1 to murine bone marrow cells was performed. A frequent MLL fusion, MLL-AF10(OM-LZ), was used as a positive control. Results: Two MLL-EB1 immortalized cell lines (ME1 and ME2G), and a MLL-AF10(OM-LZ) immortalized cell line (12G) were generated. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) enable hematopoietic stem cell transplantation (HCT) through their ability to replenish the entire blood system. Proliferation of HSCs is linked to decreased reconstitution potential, and a precise regulation of actively dividing HSCs is thus essential to ensure long-term functionality. This regulation becomes important in the transplantation setting where HSCs undergo proliferation followed by a gradual transition to quiescence and homeostasis. more...

(Submitter supplied) Chronic myeloid leukemia is a disease originated at the level of hematopoietic stem cell, characterized by the abnormal overproduction and accumulation, both in blood and bone marrow, of myeloid cells. Treatment options include tyrosine kinase inhibitors that inhibit BCR-ABL activity, however some patients develop resistance to these drugs and has been asociated to the stem cells We have performed a comparative analysis of the global gene expression profiles between CML and normal HSCs. more...

(Submitter supplied) We used a mouse model of human AML induced by the MLL-AF9 fusion oncogene, and an epigenetic shRNA library to screen for novel potential drug targets. One of the best candidate drug targets identified in these screens was Jmjd1c. Depletion of Jmjd1c impairs growth and colony formation of mouse MLL-AF9 cells in vitro, as well as establishment of leukemia after transplantation. Depletion of JMJD1C impairs expansion and colony formation of human leukemic cell lines, with the strongest effect observed in the MLL-rearranged ALL cell line, SEM. more...

(Submitter supplied) We found that composition of cell subsets within the CD34+ cell population is markedly altered in chronic phase (CP) chronic myeloid leukemia (CML). Specifically, proportions and absolute cell counts of common myeloid progenitors (CMP) and megakaryocyte-erythrocyte progenitors (MEP) are significantly greater in comparison to normal bone marrow whereas absolute numbers of hematopoietic stem cells (HSC) are equal. more...

(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) Local renin antiotensin systems have been identified for many extra-renal sites. Bone marrow has been proposed as one such site, although the nature of the renin-expressing cell type(s) has not been established. Affymetrix microarrays were used to characterize the expression profile of renin-expressing GFP positive cells.
