Affymetrix Barley Genome Array (barley1)
Description
Barley florets (cv. Morex) were treated with 2.0 microgram deoxynivalenol per floret via a 10 microliter solution or mock inoculated with water. Samples were collected at 1, 12, 24, and 48 hours after inoculation. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Stephanie A. Gardiner. The equivalent experiment is BB62 at PLEXdb.]

Description
Previous studies have reported that microglia depletion leads to impairment of synapse formation and these cells rapidly repopulate from CNS progenitors. However, the impact of microglia depletion and repopulation on the long-term state of the CNS environment has not been characterized. Here, we found by RNA-seq analysis that acute and synchronous microglia depletion results in a type 1-interferon inflammatory signature in degenerating somatosensory cortex in microglia-depleted mice. Transcriptomic and mass cytometry analysis of repopulated microglia demonstrates an interferon regulatory factor 7-driven activation state. Minocycline and anti-IFNAR1 antibody treatment attenuate the CNS type-1 interferon-driven inflammation and restore microglia homeostasis. Together, we found that acute microglia ablation induces a type-1 interferon activation state of grey matter microglia associated with acute neurodegeneration. Overall design: RNAseq analysis of brain cortical tissue from control and microglia-depleted mice.

Description
While skeletal myogenesis is tightly coordinated by myogenic regulatory factors including MyoD and myogenin, chromatin modifications have emerged as vital mechanisms of myogenic regulation. We have previously established that bexarotene, a clinically approved agonist of retinoid X receptor, promotes the specification and differentiation of skeletal muscle lineage. Here, we examine a genome-wide impact of rexinoids on myogenic differentiation through integral RNA-seq and ChIP-seq analyses. We found that bexarotene promotes myoblast differentiation through the coordination of exit from the cell cycle and the activation of muscle-related genes. We uncovered a new mechanism of rexinoid action which is mediated by the nuclear receptor and largely reconciled through a direct regulation of MyoD gene expression. In addition, we determined a rexinoid-responsive residue-specific histone acetylation at a distinct chromatin state associated to MyoD and myogenin. Thus, we provide novel molecular insights into the interplay between retinoid X receptor signaling and chromatin states pertinent to myogenic programs in early myoblast differentiation. Overall design: We have profiled the global effect of bexarotene, a selective agonist of retinoid X receptor on myoblast gene expression by RNA-seq analysis using RNA isolated from C2C12 myoblasts following 12 or 24 hours of differentiation in the presence and absence of 50 nM bexarotene, with 2 biological replicates. Proliferating myoblasts were used as controls.

Description
CTSK-mGFP positive cells from Day 6 old mouse femurs were sorted as single cells into 384 well plates pre-loaded with unique barcoded RT-primers. After sorting, cells were snap frozen on dry ice before being submitted to the New York Genome Center (NYGC) for cDNA synthesis and library preparation. The FACS profile for all the sored cells were collected to co-relate with gene expression. Overall design: Mouse femur was obtained from mice within the same litter. Femur samples was subjected to collagenase digestion, and single cell suspension was obtained. The samples were stained for FACS antibodies and single cell sorting was performed into two individual 384 well plates. The experiment has two replicates from two independant animals. The samples were always kept discrete.

Description
AZD1208 is a novel PIM kinase inhibitor that we have shown inhibits tumorigenesis in tissue recombination models, Myc-CaP allograft models, and human prostate cancer xenografts. We sought to determine the intracellular pathways that are responsible for the anti-tumor effect. To this end we used the tissue recombination protocol to implant MYCCaP cells into castrated mice. MYCCaP cells are an androgen-dependent mouse cell line that overexpresses the oncogene MYC. The mice used for implantation were castrated, so any tumors that result from the grafting procedure are androgen-independent. The grafted mice were divided into a control population receiving vehicle, and a test population receiving AZD1208. The tumors were harvested and in vitro cell lines were made. The new cell lines have been perpetuated in androgen-depleted media.

Description
GS-5759 is a bifunctional ligand composed of a quinolinone-containing pharmacophore found in several 2-adrenoceptor agonists linked covalently to a phosphodiesterase 4 inhibitor (PDE4) related to GSK 256066 by a pent-1-yn-1-ylbenzene spacer. The object of the study was to detemine if gene expression changes induced by GS-5759 were replicated by a 2-adrenoceptor agonist (indacaterol; Ind) and a PDE4 inhibitor (GSK 256066; GSK) in combination.

Description
Electrochemical gradients of monovalent cations across the plasma membrane (high intracellular potassium, [K+]i vs low intracellular sodium, [Na+]i) are created by the Na+,K+-pump and determine a large variety of physiologically important processes. We hypothesized that transcriptomics changes triggered by hypoxia are at least partially caused by Na+i/K+i-mediated excitation-transcription coupling .
