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

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We compared the transcriptomes of isogenic diploid fibroblasts expressing progerin or elevated levels of wild-type prelamin A with that of wild-type fibroblasts. We subsequently used the reversion towards normal of two phenotypes, reduced cell growth and dismorphic nuclei, by treatment with farnesyltransferase inhibitor (FTI) or overexpression of ZMPSTE24, as a filtering strategy to identify genes linked to the onset of these two phenotypes.
Publication Title
A filtering strategy identifies FOXQ1 as a potential effector of lamin A dysfunction.

Description
Single O-GlcNAc modification orchestrate by O-GlcNAc Transferase (OGT) and O-GlcNAcase (OGA alias MGEA5) enzymes, affects signal transduction and gene expression by chromatin modulation. We developed Oga deleted MEF (mouse embryonic fibroblast) cells to investigate effects of O-GlcNAc modification in mice. RNA isolated from Mouse Embryonic Fibroblast cells generated from Oga Knock out (KO) Heterozygous (Het) and wild type (WT) cells and subjected to microarray analysis.

Description
We isolated RNA from sorted common myeloid progenitor cells from wild-type fetal liver, wild-type adult bone marrow, transgenic Lin28b bone marrow, let-7b/c knock-out bone marrow, and Lin28b-deficient fetal liver and compared mRNA expression profiles. Overall design: Examination of mRNA expression in common myeloid progenitors from multiple developmental time points and genotypes. Please note that iLin28* samples represent Lin28-induced samples, while the iLin28_*_vavcre samples represent hematopoietic-specific induction of Lin28.

Description
We aimed to identify specific biomarkers of IFN-beta bioactivity in order to compare their gene expression induction by type I IFNs with the MxA, and to investigate their potential role in MS pathogenesis. Gene expression microarrays were performed in PBMC from MS patients who developed neutralizing antibodies (NAB) to IFN-beta. Nine genes followed patterns in gene expression over time similar to the MX1 and were selected for further experiments: IFI6, IFI27, IFI44L, IFIT1, HERC5, LY6E, RSAD2, SIGLEC1, and USP18. In vitro experiments revealed specific induction of selected biomarkers by IFN-beta but not IFN-gamma, and several markers, in particular USP18 and HERC5, were significantly induced at lower IFN-beta concentrations and more selective than the MX1 as biomarkers of IFN-beta bioactivity. In addition, USP18 expression was deficient in MS patients compared with healthy controls (p=0.0004). We propose specific biomarkers that may be considered in addition to the MxA to evaluate IFN-beta bioactivity, and to further explore their implication in MS pathogenesis.
