Description
CCAAT/enhancer binding protein ß (C/EBPß) is a transcription factor that regulates the expression of important pro-inflammatory genes in microglia. Mice deficient for C/EBPß show protection against excitotoxic and ischemic CNS damage but the involvement of the various C/EBPß expressing cell types in this neuroprotective effect is not solved. Since C/EBPß-deficient microglia show attenuated neurotoxicity in culture we hypothesized that specific C/EBPß deficiency in microglia could be neuroprotective in vivo. In this study we have tested this hypothesis by generating mice with myeloid C/EBPß deficiency. Mice with myeloid C/EBPß deficiency were generated by crossing LysMCre and C/EBPßfl/fl mice . Primary microglial cultures from C/EBPßfl/fl (named here as WT) and LysMCre-C/EBPßfl/fl (named here as KO) mice were treated with lipopolysaccharide ± interferon ? (IFN?) for 6 h and gene expression was analyzed by RNA sequencing. LysMCre-C/EBPßfl/fl mice showed an efficiency of C/EBPß deletion of 100% in cultured microglia. Transcriptomic analysis of C/EBPß-deficient primary microglia revealed C/EBPß-dependent expression of 1068 genes, significantly enriched in inflammatory and innate immune responses GO terms. This study provides new data that support a central role for C/EBPß in the biology of activated microglia. Overall design: LysMCre-C/EBPßfl/fl genotype (12 samples): 4 samples treated with LPS, 4 with LPS +IFNg, and 4 vehicle. C/EBPßfl/fl genotype (9 samples): 3 samples treated with LPS, 3 with LPS +IFNg, and 3 vehicle. Design Case (Treatment LPS or LPS +INF) control (No treatment or vehicle) in LysMCre-C/EBPßfl/fl genotype and in C/EBPßfl/fl genotype

Description
Many questions about the regulation, functional specialization, computational prediction, and evolution of genomic imprinting would be better addressed by having an exhaustive genome-wide catalog of genes that display parent-of-origin differential expression. As a first-pass scan for novel imprinted genes, we performed mRNA-seq experiments on E17.5 mouse placenta cDNA samples from reciprocal cross F1 progeny of AKR and PWD mouse strains, and quantified the allele-specific expression and the degree of parent-of-origin effect transcriptome-wide. We confirmed the imprinting status of 23 known imprinted genes in the placenta, and found that 12 genes reported previously to be imprinted in other tissues are also imprinted in mouse placenta. Through a well-replicated design using an orthogonal technology, we verified five novel imprinted genes that are not known to be imprinted in mouse. It appears that most of the strongly imprinted genes have already been identified, at least in the placenta, and that evidence supports perhaps 100 additional weakly imprinted genes. Despite previous appearance that the placenta tends to display an excess of maternally-expressed imprinted genes, when the full set of genes is uniformly scored as in this study, this maternal bias disappeared. Overall design: Examine allelic expression in E17.5 placenta tissues from two individual samples, one from each of the two reciprocal crosses.

Description
In this study, we initially screened over 1400 natural products for capacity to inhibit the kinetic enzyme activity of nuclear HDACs isolated from SK-MEL-3 cells. From these findings we evaluate whole transcriptome changes that occur at a 24 hour time point in SK-ME-3 cells in the presence of a known HDAC inhibitor (Trichostatin A) (1uM) or a natural product HDAC inhibitor Grapeseed Extract (120ug/ml), both tested at sub-lethal concentrations relative to untreated controls. Microarrays were acquired for mRNAs and long intergenic non-coding RNA transcripts using the GeneChip Human 2.1ST ARRAY by Affymetrix Inc
