We have developed a method to generate muscle stem cells from pluripotent stem cells via teratoma formation. The goal of this study is to compare the transcriptome of a7+ VCAM+ myogenic cells derived from pluripotent stem cells versus satellite cells Overall design: RNA from a7+ VCAM+ myogenic cells derived from teratoma, transplanted muscles, E14.5 mouse embryos, and hindlimbs of 8-week-old mice. In 3 biological replicates

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
During embryogenesis, the endothelial and the hematopoietic lineages first appear during gastrulation in the blood island of the yolk sac. We have previously reported that an Ets variant gene 2 (Etv2/ER71) mutant embryo lacks hematopoietic and endothelial lineages, however, the precise roles of Etv2 in yolk sac development remains unclear.
Publication Title
Etv2 is expressed in the yolk sac hematopoietic and endothelial progenitors and regulates Lmo2 gene expression.

Description
Juvenile pilocytic astrocytoma (JPA) is one of the most common brain tumors in children. The expression profiles of 21 JPAs, determined using Affymetrix GeneChip U133A, were compared with subjects with normal cerebella. The genes involved in neurogenesis, cell adhesion, synaptic transmission, central nervous system development, potassium ion transport, protein dephosphorylation, and cell differentiation were found to be significantly deregulated in JPA. These 21 JPAs were further clustered into two major groups by unsupervised hierarchical clustering using a set of 848 genes with high covariance (0.5-10). Supervised analysis with Significance Analysis of Microarrays software between these two potential subgroups identified a list of significant differentially expressed genes involved in cell adhesion, regulation of cell growth, cell motility, nerve ensheathment, and angiogenesis. Immunostaining of myelin basic protein on paraffin sections derived from 18 incompletely resected JPAs suggests that JPA without myelin basic proteinpositively stained tumor cells may have a higher tendency to progress.

Description
We identified distict mesodermal sub-populations based on Endoglin (Eng) and Flk1 expression in Brachyury (Bry) positive cells. By using whole-transcriptome analysis, we further characterized these populations and how they changed when Wnt pathway is inhibited Overall design: Reaggregates mRNA profiles of unsorted, Flk1+ Eng+, and Flk1- Eng+ samples were generated by deep sequencing, in triplicate , using Ilumina.

Description
Skeletal myogenic commitment of human pluripotent cells can be achieved by doxycycline-inducible expression of the transcription factor PAX7. To gain further insights on PAX7 function during this process, we performed a time course whole transcriptome analysis of differentiating H9 human embryonic stem cells from doxycycline-treated and untreated cultures. In addition, we identified the genomic binding of PAX7 in one of the selected time point (referred as PAX7+ proliferating myogenic progenitors). Overall design: Gene expression profiling was performed on biological replicates from differentiating H9 cells at the following time points: PAX7+ mesodermal cells (day 14), PAX7+ proliferating myogenic progenitors (approximately day 23), and differentiated myocytes (differentiation stage – around day 30; 7 days in the absence of PAX7 induction). Since PAX7 expression is doxycycline inducible, we also collected uninduced control samples at the same time points (termed mesodermal cells for day 14 and proliferating cells for day 23). PAX7 genomic binding was assessed in day 23 dox-treated cultures.

Description
Sle1c is a sublocus of the NZM2410-derived Sle1 major susceptibility locus. We have previously shown that Sle1c contributes to lupus pathogenesis by conferring CD4+ T cell-intrinsic hyperactivation and increased susceptibility to chronic graft-versus-host disease (cGVHD) that mapped to the centromeric portion of the locus. In this study, we have refined the centromeric sublocus to a 675Kb interval, termed Sle1c2. Recombinant congenic strains expressing Sle1c2 exhibited a T cell-intrinsic CD4+ T cell hyperactivation and cGVHD susceptibility, similar to mice with the parental Sle1c.
Publication Title
Murine lupus susceptibility locus Sle1c2 mediates CD4+ T cell activation and maps to estrogen-related receptor γ.

Description
Protein synthesis belongs to the most energy consuming processes in the cell. Lowering oxygen tension below normal (hypoxia) causes a rapid inhibition of global mRNA translation due to the decreased availability of energy. Interestingly, subsets of mRNAs pursue active translation under such circumstances. In human fibrosarcoma cells (HT1080) exposed to prolonged hypoxia (36 h, 1% oxygen) we observed that transcripts are either increasingly or decreasingly associated with ribosomes localized at the endoplasmic reticulum (ER). In a global setting it turned out that only 31% of transcripts showing elevated total-RNA levels were also increasingly present at the ER in hypoxia. These genes, regulated by its expression as well as its ER-localization, belong to the gene ontologys hypoxia response, glycolysis and HIF-1 transcription factor network supporting the view of active mRNA translation at the ER during hypoxia. Interestingly, a large group of RNAs was found to be unchanged at the expression level, but translocate to the ER in hypoxia. Among these are transcripts encoding translation factors and >180 ncRNAs. In summary, we provide evidence that protein synthesis is favoured at the ER and, thus, partitioning of the transcriptome between cytoplasmic and ER associated ribosomes mediates adaptation of gene expression in hypoxia.

Description
We report gene expression data for FACS sorted zebrafish mpeg1:mCherry + and mpx:EGFP + cells collected from whole embryos at 72 hours post fertilization (hpf). We also report gene expression data for the remaining, transgene negative, portion of these embryos. Overall design: ~1,000 mpeg1:mCherry+; mpx:EGFP+ transgenic embryos were homogenized, filtered, and sorted using FACS into PBS, collecting >50,000 cells for each of the three populations: mpeg1:mCherry+, mpx:EGFP+ and double negative (no double positive cells were collected as there was almost no overlap between mCherry and EGFP expression).
