Description
We inoculated ARPE-19 human retinal pigment epithelial cells with EBOV, and followed course of infection by immunocytochemistry and measurement of titer in culture supernatant. To interrogate transcriptional responses of infected cells, we combined RNA sequencing with in silico pathway, gene ontology, transcription factor binding site and network analyses. Human retinal pigment epithelial cells were permissive to infection with EBOV, and supported viral replication and release of virus in high titer. Unexpectedly, 28% of 560 up-regulated transcripts in EBOV-infected cells were type I IFN responsive, indicating a robust type I IFN response. Overall design: Transcriptomic profiles of ARPE-19 cells 24 hours following infection with EBOV or mock-infection

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
KATP opposes depolarization of cells in the heart, smooth muscle, and other tissues by permitting the efflux of potassium ions and this efflux is evidently required to prevent unopposed vasoconstriction and insufficiency of coronary artery blood flow triggered by one or more cytokines induced in response to LPS. The cytokine(s) involved must elicit a dysfunctional response in the Kir6.1-deficient environment, and to gain further insight into the effects of the mutation, we examined the transcriptional status of whole heart, isolated from normal C57BL/6J mice or KcnJ8Md/Md mice, before and after injection of 1 g of LPS

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Murine Cytomegalovirus (MCMV) infection leads to early activation of various immune cells, including B and T lymphocytes, before the actual initiation of antigen-specific adaptive immunity. This activation is partly driven by innate cytokines, including type I interferon (IFN), which are induced early after infection. The objective of this study was to address the role of type I IFN in shaping early/innate B and T cell responses to a primary acute viral infection.

Description
A highly metastatic breast cancer cell line, 4T1, was used to generate stable Wnt5a expressing and vector only control cells. Cells were generated using lentivirus infection and selection with blasticidin. Expression of Wnt5a was confirmed using western blot. Cell behaviour was characterized. Wnt5a expressing cells exhibited reduced migration in a transwell assay and reduced metastasis in a tail vein injection assay. Growth was not significantly affected.

Description
To investigate differential gene expression that might account for the differing glomerular phenotype of NPHS2-Cre +/+ mice when compared with wild-type control, including altered GBM thickness, loss of normal foot process morphology, and decrease in podocyte number, RNA sequencing analysis was performed on glomeruli extracted from both NPHS2-Cre +/+ and wild-type control mice. Overall design: Following isolation of glomeruli using Dynabeads from NPHS2-Cre +/+ and wild-type control mice (n=2 biological replicates per genotype, singly isolated), total RNA was extracted and RNA samples were submited for sample preparation and sequencing.

Description
It is well known that both recipient cells and donor nuclei demonstrate a mitotic advantage as observed in the traditional reprogramming with somatic cell nuclear transfer (SCNT). However, It is not known whether a specific mitotic factor plays a critical role in reprogramming. Here we identify an isoform of human bromodomain-containing 3 (BRD3), BRD3R (BRD3 with Reprogramming activity), as a reprogramming factor. BRD3R positively regulates mitosis during reprogramming, upregulates a large set of mitotic genes at early stages of reprogramming, and associates with mitotic chromatin. Interestingly, a set of the mitotic genes upregulated by BRD3R constitutes a pluripotent molecular signature. The two BRD3 isoforms display differential binding to acetylated histones. Our results suggest a molecular interpretation for the mitotic advantage in reprogramming, and show that mitosis may be a driving force of reprogramming. Overall design: Human BJ cells transduced with lentiviral particles of the conventional reprogramming factors (OCT3/4, SOX2 and KLF4) were used as controls. Two types of controls were used: 1) BJ transduced with OSK (OCT4, SOX2 and KFL4) viruses; 2) BJ cells transduced with OSK plus GFP viruses. Experimental treatment was BJ cells transduced with OSK plus BRD3R viruses. RNA was extracted from cells at day 3 of reprogramming because the reprogramming cells are still homogeneous and transgenes are well expressed at this time point.

Description
Rad21 is a subunit of cohesin. The main function of cohesin is to hold replicated chromosomes together until cells divide, but it also plays a role in gene expression. To find out which genes might be regulated by cohesin, a study was conducted to look for global changes in gene expression in zebrafish embryos lacking cohesin component Rad21.
Publication Title
Positive regulation of c-Myc by cohesin is direct, and evolutionarily conserved.

Description
In addition to satisfying the metabolic demands of cells, mitochondrial metabolism helps regulate immune cell function. To date, such cell-intrinsic metabolic-immunologic cross-talk has only been described operating in cells of the immune system. Here we show that epidermal cells utilize fatty acid -oxidation to fuel their contribution to the immune response during cutaneous inflammation. By live imaging metabolic and immunological processes within intact zebrafish embryos during cutaneous inflammation, we uncover a mechanism where elevated -oxidation-fueled mitochondria-derived reactive oxygen species within epidermal cells helps guide matrix metalloproteinase-driven leukocyte recruitment. This mechanism requires the activity of a zebrafish homolog of the mammalian mitochondrial enzyme, Immunoresponsive gene 1. This study describes the first example of metabolic reprogramming operating within a non-immune cell type to help control its contribution to the immune response. Targeting of this metabolic-immunologic interface within keratinocytes may prove useful in treating inflammatory dermatoses.
