(Submitter supplied) Latexin is a hematopoietic stem cell (HSC) regulatory gene. Its deletion leads to the expansion of HSC population. The underlying mechanims are largely unknown. We therefore perfored microarrary analysis in HSCs with (Lxn-/-) and without (wild-type, WT) latexin deletion, and determined genes that were altered by latexin deletion. This led us to identify the molecular mechanims by which latexin regulates HSC function.

(Submitter supplied) The Hematopoietically-expressed homeobox transcription factor (Hhex) is important for the maturation of definitive hematopoietic progenitors and B-cells during development. We have recently shown that in adult hematopoiesis, Hhex is dispensable for maintenance of hematopoietic stem cells (HSCs) and myeloid lineages but essential for the commitment of Common Lymphoid Progenitors (CLPs) to lymphoid lineages. more...

(Submitter supplied) Although Hematopoietic Stem Cell Transplantation (HSCT) routinely treats hematologic disease, many patients experience adverse outcomes. Understanding the molecular regulation of HSC engraftment is paramount to improving HSCT regimens. Here, we executed a large-scale transplant-based functional screen for novel regulators of HSC repopulation.. Of >50 gene candidates tested, 18 were required for in vivo hematopoietic repopulation and two were detrimental to repopulation, as their loss enhanced this activity. 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) The mRNA m6A reader YTHDF2 is overexpressed in human acute myeloid leukaemias. To understand the role of YTHDF2 in normal haematopoiesis and ageing, we performed SMART-seq on haematopoietic stem cells (HSCs) derived from young and aged (1 year old) mice. In parallel, to identify transcripts likely methylated in HSCs we performed meRIP-seq analysis of c-Kit+ cells.

(Submitter supplied) Recent epidemiological studies have shown that cancer-associated DNMT3A mutations can be detected in the blood of a large proportion of asymptotic elderly individuals. It is important to understand how these mutations provide a competitive advantage to HSCs and allow them to establish clonal dominance. Here we demonstrate that the stress of serial HSC transplantation immortalizes Dnmt3a-null HSCs.

(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...
