Description
G9a is an H3K9m2 methyltransferase, which is critical in controlling gene suppression and DNA methylation. We used microarray analysis to identify the target genes that are regulated by G9a in MDA-MB231 cells, in which E-cadherin is silenced.
Publication Title
G9a interacts with Snail and is critical for Snail-mediated E-cadherin repression in human breast cancer.

Description
Background. Chronic fatiguing illness remains a poorly understood syndrome of unknown pathogenesis. We attempted to identify biomarkers for chronic fatiguing illness using microarrays to query the transcriptome in peripheral blood leukocytes. Methods. Cases were 44 individuals who were clinically evaluated and found to meet standard international criteria for chronic fatigue syndrome or idiopathic chronic fatigue, and controls were their monozygotic co-twins who were clinically evaluated and never had even one month of impairing fatigue. Biological sampling conditions were standardized and RNA stabilizing media were used. These methodological features provide rigorous control for bias resulting from case-control mismatched ancestry and experimental error. Individual gene expression profiles were assessed using Affymetrix Human Genome U133 Plus 2.0 arrays. Findings. There were no significant differences in gene expression for any transcript. Conclusions. Contrary to our expectations, we were unable to identify a biomarker for chronic fatiguing illness in the transcriptome of peripheral blood leukocytes suggesting that positive findings in prior studies may have resulted from experimental bias.

Description
Besides the established selection criteria based on embryo morphology and blastomere number, new parameters for embryo viability are needed to improve the clinical outcome of in vitro fertilization (IVF) and more particular of elective single embryo transfer (eSET). The aim of the study was to analyse genome-wide whether the embryo viability was reflected by the expression of genes in the oocyte surrounding cumulus cells. Early cleavage (EC) was chosen as a parameter for embryo viability.
Publication Title
Differential gene expression in cumulus cells as a prognostic indicator of embryo viability: a microarray analysis.

Description
Cells are constantly exposed to stress. Most of those stresses do not necessarily cause cell death or visible damage. The present study explores the way the immune system responds to such sub lethal stressed cells.
Publication Title
Cells exposed to sublethal oxidative stress selectively attract monocytes/macrophages via scavenger receptors and MyD88-mediated signaling.

Description
Previously, long-term effects on body weight and reproductive performance have been demonstrated in the chicken model of prenatal protein undernutrition by albumen removal. Introduction of such persistent alterations in phenotype suggests stable changes in gene expression. A genome-wide screening for differences in hepatic transcriptome by RNA-Seq was performed in adult Isa Brown hens (55 weeks of age). Albumen-deprived hens were created by removal of 3 ml of the albumen from fertilized eggs and replacement with saline early during embryonic development (embryonic day 1). Results were compared to mock-treated sham hens and non-treated control hens. Correlation between relative expression levels obtained from the RNA-Seq and qPCR results was very high (Pearson’s correlation coefficiënt = 0.85), confirming the validity of the RNA-Seq results. In addition, after expansion of the sample size, 7 out of 15 selected genes demonstrated the same significant gene expression differences in the qPCR as in the RNA-Seq dataset, and were thus biologically confirmed. Grouping of the differentially expressed (DE) genes according to biological functions revealed the involvement of processes such as ‘embryonic and organismal development’, ‘organ morphology’, ‘organ and tissue development’, ‘reproductive system development and function’. Molecular pathways that were altered were ‘amino acid metabolism’, ‘molecular transport’, ‘small molecule biochemistry’, ‘cell death and survival’, ‘cell-to-cell signaling and interaction’, ‘carbohydrate metabolism’ and ‘protein synthesis’. In conclusion, the present results demonstrated for the first time that prenatal protein undernutrition by albumen removal leads to long-term alterations of the hepatic transcriptome in the chicken. Overall design: 3 biological replicates per group (control, sham, albumen-deprived) were analyzed
