Affymetrix HT Mouse Genome 430A Array (htmg430a)
Description
Identify genes in the aorta whose expressions under genetic regulation in the Hybrid Mouse Diversity Panel (HMDP). The HDMP is comprised of classical inbred and recombinant inbred wild-type mice. The RMA values of genes were used for genome-wide association as described in Bennett et al. Genome Research 2010 (PMID 20054062). These data were used to identify candidate genes at loci associated with atherosclerosis.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The endoplasmic reticulum (ER) is the site of secretory lipoprotein production and de novo cholesterol synthesis, yet little is known about how these activities are coordinated with each other, or with the activity of the COPII machinery, which transports ER cargo to the Golgi. The Sar1B component of this machinery is mutated in Chylomicron Retention Disorder, establishing that this Sar1 isoform secures delivery of dietary lipids into the circulation.
Publication Title
The endoplasmic reticulum coat protein II transport machinery coordinates cellular lipid secretion and cholesterol biosynthesis.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The therapeutic potential of pro-resolution factors in determining the outcome of inflammatory events has gained ground over the past decade. However, the attention has been focused on the non-genomic effects of these endogenous, anti-inflammatory substances. In this study, we have focused our attention on identifying specific annexin 1 (AnxA1) protein/ALX receptor mediated gene activation, in an effort to identify down-stream genomic targets of this well-known, glucocorticoid induced, pro-resolution factor.
Publication Title
Downstream gene activation of the receptor ALX by the agonist annexin A1.

Description
Pan-Hdac inhibitors (HDACi) are endowed with a potent anti-inflammatory activity, but the relative role of each of the eleven Hdac proteins sensitive to HDACi to the inflammatory gene expression program is unknown. Using an integrated genomic approach we found that Hdac3-deficient macrophages are unable to activate almost half of the inflammatory gene expression program when stimulated with lipopolysaccharide (LPS). A large part of the activation defect is due to loss of basal and LPS-inducible expression of IFNb, which in basal cells maintains Stat1 protein levels, and after stimulation acts in an autocrine/paracrine manner to promote a secondary wave of Stat1-dependent gene expression. We show that loss of Hdac3-mediated repression of nuclear receptors leads to hyperacetylation of thousands of genomic sites and associated gene derepression. The upregulation of the constitutively expressed prostaglandin endoperoxide synthase, Ptgs1 (Cox-1), has a causative role in the phenotype, since its chemical inhibition reverts the Ifnb activation defect. These data may have relevance for the use of selective Hdac inhibitors as anti-inflammatory agents.

- Affymetrix Human Genome U219 Array (hgu219)
Description
Activation of the innate immune system leading to a persistent state of low-grade of tissue inflammation greatly influences the risk of developing metabolic complications associated with obesity. In this study, we characterized the inflammatory state in adipose tissue from obese patients and explored the potential of the specialized pro-resolving mediator (SPM) resolvin D1 (RvD1) to actively terminate inflammation and promote its resolution. By means of high-troughput transcritomic analysis we identified a cytokine-related molecular signature in obese omental adipose tissue, characterized by a remarkable overexpression of interleukin (IL)-6, IL-1 and IL-10 associated with a concomitant increase in macrophage infiltration, which gradually increased in a body mass index-dependent manner.

Illumina HiSeq 2000
Description
In this study, we analyzed the impact of a mutation in the wrn-1 gene compared to wild type worms and the dietary supplementation of vitamin C on the global mRNA expression of the whole C. elegans by the RNA-seq technology. Overall design: Whole C. elegans mRNA profiles at the L4 stage of wild type and wrn-1(gk99) mutant animals treated with or without 10 mM ascorbate were generated by deep sequencing, in triplicate, using the HiSeq 2000 machine form Illumina. Detailed statistics on the quality of the reads were calculated with FastQC (http://www.bioinformatics.babraham.ac.uk/projects/fastqc/). The 50 base pairs raw sequences were aligned on the C. elegans ce10/W220 genome with TopHat using the Ensembl annotations provided with the Illumina iGenomes. The htseq-count software (http://www-huber.embl.de/users/anders/HTSeq) was used to count the number of reads aligned to each gene. These counts were then normalized relative to the sequencing depth with DESeq.
