Expression data from 45 Month Slovak Children with high POPs exposure

ABSTRACT: Exposure to Persistant Organic Pollutants (POPs) is known to cause serious health effects in human but the gene expression profiles leading to development of differnet diseases and disorders are not fully understood. The knowledge of global gene expression will help us to devlop early disease or disorder biomarkers for POP induced health effects. We used microarrays to detail the global gene expression profile underlying the effects of high POP exposure to Slovak 45 month children leading to identification of distinct classes of up-regulated and down-regulated genes and cellular processes. High POP Exposed 45 month Slovak Children: Extraction of total RNA was performed by using Qiagen PAXgene Blood RNA Kit IVD according to the manufacturer's instructions. Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 microgram of total RNA (Expression Analysis Technical Manual, 2001, Affymetrix). Following fragmentation, 10 microgram of cRNA were hybridized for 16 hr at 45C on GeneChip Human Genome Array (HGU133 plus 2.0). GeneChips were washed and stained in the Affymetrix Fluidics Station 450 and scanned using the Affymetrix GeneArray Scanner 3000. The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 150.

Integrative DNA, RNA and protein evidence connects TREML4 to coronary artery calcification

Project description:Peripheral blood RNA-Seq from human coronary artery calcification cases and controls; Coronary artery calcification (CAC) is a heritable and definitive morphologic marker of atherosclerosis that strongly predicts risk for future cardiovascular events. To search for genes involved in CAC, we used an integrative transcriptomic, genomic, and protein expression strategy using next-generation DNA sequencing in the discovery phase with follow-up studies using traditional molecular biology and histopathology techniques. Eight cases and eight controls (matched for gender, age and ancestry); RNA sequencing of peripheral blood from a discovery set of eight CAC cases and eight matched controls was used to identify dysregulated genes, which were validated using the NanoString® and Affymetrix GeneChip® Human Exon ST Array platforms. The median CAC scores for cases in the screening and validation sets were 1531.5 and 668.5, respectively, while all controls had a score of zero.

Autoinflammation with enhanced type I interferon signaling due to DNASE2 mutations

Project description:In humans, microbial nucleic acid recognition serves as the major stimulus to an antiviral response, implying a requirement for cellular mechanisms to limit misrepresentation of self nucleic acids as non-self and the subsequent induction of type I interferon-mediated autoinflammation. This RNA-seq study was done on individuals with upregulated type I interferon signaling autoinflammatory disease.
