Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To find out genes regulated by geranylgeraniol (GGOH) treatment in peritoneal macrophage, we compared gene expression of cells treated with 200ng ml LPS and 250 micromolar compactin versus 200ng ml LPS, 250 micromolar compactin and 100micromolar GGOH.
Publication Title
Sufficient production of geranylgeraniol is required to maintain endotoxin tolerance in macrophages.

Description
Ubiquitylation plays an important role in the control of Na+ homeostasis by the kidney. It is well established that the epithelial Na+ channel ENaC is regulated by the ubiquitin-protein ligase NEDD4-2, limiting ENaC cell surface expression and activity. Ubiquitylation can be reversed by the action of deubiquitylating enzymes (DUBs). One such DUB, USP2-45, was identified previously as an aldosterone-induced protein in the kidney, and is also a circadian output gene. In heterologous expression systems USP2-45 binds to ENaC, deubiquitylates it and enhances channel density and activity at the cell surface. Because the role of USP2-45 in renal Na+ transport had not been studied in vivo, we investigated here the effect of Usp2 gene inactivation in this process. We demonstrate first that the USP2-45 protein has a rhythmic expression with a peak at ZT12. Usp2-KO mice did not show any differences to wild-type littermates with respect to the diurnal control of Na+ or K+ urinary excretion and plasma levels neither on standard diet, nor after acute and chronic changes to low and high Na+ diets, respectively. Moreover, they had similar aldosterone levels either at low or high Na+ diet. Blood pressure measurements using telemetry did not reveal variations as compared to control mice. Usp2-KO did neither display alternations in ENaC or Na+,Cl--cotransporter (NCC) expression, nor were there any changes in regulatory protein levels, as evidenced by immunoblotting and transcriptome analysis. We conclude that USP2-45 is not crucial for the regulation of Na+ balance or maintenance of blood pressure in vivo.

- Affymetrix Maize Genome Array (maize)
Description
At 35 DAP whole kernels (pericarp + endosperm + embryo) without glumes of green house grown ears of heterozygous (+/bt2-H2328), self-pollinated plants were visually divided into pools of phenotypically normal looking kernels (small indentation, slightly smaller than mutant kernels, genotype +/+ or +/bt2-H2328) and pools of phenotypically mutant kernels (plump, round kernels, slightly larger than normal kernels, genotype bt2-H2328/bt2-H2328). Pools consisted of 4 kernels. 3 different ears were used for a biological duplicate.

Description
This study sought to evaluate the effects of dietary MeHg exposure on adult female yellow perch (Perca flavescens) and zebrafish (Danio rerio) reproduction by relating controlled exposures with subsequent reproductive effects. Yellow perch were used in the study for their socioeconomic and ecological importance within the Great Lakes basin, and the use of zebrafish allowed for a detailed analysis of the molecular effects of MeHg. MeHg exposures at environmentally relevant levels were done in zebrafish for a full life cycle, mimicking a realistic exposure scenario, and in adult yellow perch for twenty weeks, capturing early seasonal ovarian development. In zebrafish, several genes involved in reproductive processes were shown to be dysregulated by RNA-seq and QPCR, but no significant phenotypic or physiological changes were observed with ovarian staging, fecundity, or embryo mortality. Yellow perch did not appear to be affected by MeHg, either at a molecular level, as assessed by QPCR of eight genes in the pituitary, liver, and ovary tissue, or a physiological level, as seen with ovarian somatic index, circulating estradiol, and ovarian staging. Lack of impact in yellow perch limits the usefulness of zebrafish as a model and suggests that the reproductive sensitivity to environmentally relevant levels of MeHg differs between yellow perch and zebrafish. Overall design: 12 samples of total RNA isolated from adult zebrafish ovaries were analyzed. Each exposure group (1, 3, and 10 ppm MeHg) had three replicates, as did the vehicle control. Each sample was comprised of pooled total RNA of up to 6 individual fish.

Description
Analysis of effect of long-term cryopreservation on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that long-term cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with decreasing signal intensities over time.
