- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The transcription factor SOX17 is expressed by fetal, but not adult hematoipoietic stem cells (HSCs), and is required for the maintenance of fetal and neonatal, but not adult, HSCs. In the current study we show that ectopic expression of Sox17 in adult HSCs and transiently reconstituting multipotent progenitors was sufficient to confer increased self-renewal potential and the expression of fetal HSC genes including fetal HSC surface markers.

Description
Excessive or sustained glucocorticoid (GC) exposure causes muscle wasting. Paradoxically, moderate or transient GC exposure elicits ergogenic effects, evidenced by their widespread use as doping agents by endurance athletes and poorly understood efficacy in Duchenne muscular dystrophy (DMD), a genetic muscle wasting disease. While mechanisms underlying GC-mediated muscle wasting are well defined, the molecular basis for the latter remains unknown. In this arm of our studies, we compare expression profiles in quadriceps tissue from KLF15 transgenic (MTg) and non-Tg mice.

Illumina HiSeq 2000
Description
Purpose: Understand the synergistic relationship between the methyltransferases Set1 and Set5 in the regulation of gene expression. Methods: Total mRNA was obtained from two independent biological replicates each of wildtype (WT), set1?, set5?, SET5 Y402A and set1?set5? S. cerevisiae strains. Libraries were generated and sequenced using an Illumina HiSeq2000 platform. The sequence reads that passed quality filters were mapped using TopHat and expression levels were quantified using Cufflinks. Results: We generated FPKM expression values for each transcript and identified the differentially expressed genes using an FDR-adjusted p-value of 0.05. Subsequent data analysis was restricted to genes with fold-change greater than 1.7 relative to WT. Our results show that Set1 and Set5 have roles primarily in transcription repression. Moreover, lack of both Set1 and Set5 results in a synergistic exhacerbation of the transcriptional derepression observed in the single mutants. Further analysis revealed a specific enrichment of the Set5/Set1-repressed genes near repetitive DNA sequences of the genome. Conclusions: Our study uncovers an unexpected synergistic role of Set1 and Set5 in transcription repression of telomeric regions and Ty retrotransposons. Overall design: mRNA profiles of wildtype (WT), set1?, set5?, SET5 Y402A and set1?set5? were generated by sequencing using an Illumina HiSeq2000 platform. Two biological replicates of each strain were used.

Description
As Prdm16 deficiency reduces self-renewal potential and depletes neural stem cells in culture we decided to investigate the underlying molecular mechanisms of the neural stem cells depletion in the Prdm16 deficient animals. For the experiment we used Prdm16Gt(OST67423)Lex (Prdm16LacZ) genetrap mice obtained from the NIH Mutant Mouse Regional Resource Center (http://www.mmrrc.org/).
Publication Title
Prdm16 promotes stem cell maintenance in multiple tissues, partly by regulating oxidative stress.

Description
It has been shown previously that endothelial cells and LepR+ stromal cells are the main sources of SCF in vivo in the mouse bone marrow. We tested whether SCF from endothelial cells and/or LepR+ stromal cells is important for the maintenance of hematopoietic progenitors and erythroid progenitors in mouse bone marrow by conditional deletion of Scf from these two cell types. We discovered that Scf deletion from LepR+ stromal cells, but not endothelial cells, reduced the numbers of hematopoietic progenitors and erythroid progenitors in mice. We performed RNA-Seq on PreCFU-E and CFU-E progenitors from control mice and from mice with Scf deletion from LepR+ stromal cells. We discovered that lack of SCF from LepR+ cells induces a premature differentiation of PreCFU-E and CFU-E progenitors. Overall design: Examination of gene expression profile in 2 cell tyeps from 3 different genetic backgrounds
