Description
As part of the civil aviation safety program to define the adverse effects of ethanol on flying performance, we present results of our DNA microarray analysis of samples from a timecourse study of individuals given ethanol orally, and then evaluated by breathalyzer to monitor blood alcohol content (BAC). At five blood alcohol levels, T1-T5, blood was drawn such that the samples represented 0%, 0.04%, 0.08% BAC, and return to 0.04%, and 0.02% BAC. Microarray analysis showed that changes in gene expression could be detected across the time-course. We verified these expression changes by quantitative polymerase chain reaction (qPCR). Candidate target genes identified from the microarray analysis were clustered by expression change pattern, examined for shared functions and functional network membership. Five coordinately expressed groups were revealed and functional analysis showed shared transcription factor binding sites and functions for members of the clusters. These functions include protein synthesis and modification, expected for changes in gene expression, hematological and immune functions, expected for a blood sample, and pancreatic and hepatic function, expected as response to ethanol. The results provide a first look at changing gene expression patterns in blood during acute increase of ethanol concentration and its depletion due to metabolism or excretion and demonstrate that it is possible to detect significant changes in gene expression using total RNA isolated from whole blood. The analysis approach for this study can be utilized as part of a workflow to identify target genes by timecourse changes in gene expression that may affect pilot performance.

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.

NextSeq 500
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
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 Zebrafish Genome Array (zebrafish)
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.
