CodeLink Mouse Whole Genome Bioarray data from hematopoietic stem cells (HSCs) of miR-125a (+/+) wild-type and miR-125a knockout mice with myeloproliferative disorder (MPD)

ABSTRACT: miR-125a knockout mice develop myeloproliferative disorder (MPD). To investigate the molecular mechanisms of MPD induced by the loss of miR-125a, gene expression profiling on hematopoietic stem cells of miR-125a (+/+), (+/-) MPD, and (-/-) MPD mice was performed by using CodeLinkTM Whole Genome DNA array analysis.

Expression profiles of HSPCs overexpressing microRNA cluster 99b/let-7e/125a, miR-125a, miR-155 and empty vector.

Project description:Hematopoietic stem/progenitor cell (HSPC) traits differ between genetically distinct mouse strains. For example, DBA/2 mice have a higher HSPC frequency compared to C57BL/6 mice. We performed a genetic screen for microRNAs that are differentially expressed between LSK, LS−K+, erythroid and myeloid cells isolated from C57BL/6 and DBA/2 mice. This analysis identified 131 microRNAs that were differentially expressed between cell types and 15 that were differentially expressed between mouse strains. Of special interest was an evolutionary conserved miR-cluster located on chromosome 17 consisting of miR-99b, let-7e and miR-125a. All cluster members were most highly expressed in LSKs and down-regulated upon differentiation. In addition, these microRNAs were higher expressed in DBA/2 cells compared to C57BL/6 cells, and thus correlated with HSPC frequency. To functionally characterize these microRNAs, we overexpressed the entire miR-cluster 99b/let-7e/125a and miR-125a alone in BM cells from C57BL/6 mice. Overexpression of the miR-cluster or miR-125a dramatically increased day-35 CAFC activity and caused severe hematopoietic phenotypes upon transplantation. We showed that a single member of the miR-cluster, namely miR-125a, is responsible for the majority of the observed miR-cluster overexpression effects. Finally, we performed genome-wide gene expression arrays and identified candidate target genes through which miR-125a may modulate HSPC fate.

Gene expression analysis after miR-125a-3p over-expression in oligodendrocyte precursor cells (OPCs)

Project description:MiR-125a-3p over-expression in OPCs impairs their differentiation into fully mature oligodendrocytes. We performed a whole microarray profiling to identify new miR-125a-3p direct targets and altered signaling pathways responsible for its the detrimental effect on oligodendrocyte maturation.

Expression data on Treg cells isolated from wildtype mice and miR-125a deficient mice

Project description:We found miR-125a was a key regulator that stabilizes the commitment and immunoregulatory capacity of Treg cells.To gain insights into the general functional features of miR-125a-deficient Treg cells, we performed a genome-wide gene array analysis on Treg population isolated from the spleens of 6 to 8-week-old miR-125a-deficient and WT mice We sorted CD4+CD25hi Treg population from the spleens of 6 to 8-week-old miR-125a-deficient and their littermate WT mice. Cells were collected and total RNA was extracted for Affymetrix GeneChip®Mouse Genome 430 2.0 Array

miR-125a Confers Multi-Lineage Long-Term Repopulating Stem Cell Activity to Murine and Human Hematopoietic Progenitors

Project description:Umbilical cord blood (CB) is a non-invasive, convenient and broadly used source of hematopoietic stem cells (HSCs) for allogeneic stem cell transplantation. However, limiting numbers of HSCs remain a major constraint for its clinical application. One feasible option would be to expand HSCs to improve therapeutic outcome, however available protocols and the molecular mechanisms governing the self-renewal of HSC are unclear. Here we show that ectopic expression of a single miRNA, miR-125a, in purified murine and human multipotent progenitors (MPP) resulted in increased self-renewal and robust long-term multi-lineage repopulation in transplanted recipient mice. Using quantitative proteomics and Western blot analysis, we identified a restricted set of miR-125a targets which revealed the involvement of the MAP kinase signaling pathway in conferring long-term repopulating capacity to multipotent progenitors in human and mice. Our findings offer the innovative potential to use MPP with enhanced self-renewal activity to augment limited sources of HSC to improve clinical protocols.
