Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Characterization of genes associated with adipose tissue is key to understanding the pathogenesis of obesity and developing treatments for this disorder. Differential gene expression in the adipose tissue has been described in adulthood but none studies have been developed on childhood. The purpose of this study was to compare gene expression in omental adipose tissue from obese prepubertal and normal weight children. We selected 5 obese (BMI adjusted for age and sex z score >2) and 6 normal weight children. RNA was extracted from omental adipose tissue biopsies and cRNA was hybridizated on the human genome U133 Plus 2.0 Arrays (Affymetrix). Microarray experiments were performed for each sample, and selected group of gene expression values were confirmed with real-time RT-PCR in 10 obese and 10 normal weigth prepubertal children. 1276 genes were found to be differentially expressed at P<0.05. Of those differential genes, 201 were upregulated (Fc>2) and 42 were downregulated (Fc<-2). Genes involved in metabolic and signalling pathways were altered in childhood obesity.

Illumina MouseWG-6 v2.0 expression beadchip
Description
The distinct phenotypic and prognostic subclasses of human hepatocellular carcinoma (HCC) are difficult to reproduce in animal experiments. Here we have used in vivo gene targeting to insert an enhancer-promoter element at an imprinted chromosome 12 locus in mice, thereby converting ~1 in 20,000 normal hepatocytes into a focus of HCC with a single genetic modification. A 300 kb chromosomal domain containing multiple mRNAs, snoRNAs and microRNAs was activated surrounding the integration site. An identical domain was activated at the syntenic locus in a specific molecular subclass of spontaneous human HCCs with a similar histological phenotype, which was associated with partial loss of DNA methylation. These findings demonstrate the accuracy of in vivo gene targeting in modeling human cancer, and suggest future applications in studying various tumors in diverse animal species. In addition, similar insertion events produced by randomly integrating vectors could be a concern for liver-directed human gene therapy.

Illumina HiSeq 2000
Description
We profiled the skeletal muscle transcriptome between wild type and aB-crystallin/HspB2 knock mice exposed to normal chow and high fat diets to examine the role of aB-crystallin/HspB2 in diet induced obesity. Combined with metabolic profiling of the mice, these data reveal that aB-crystallin/HspB2 is involved in the genesis of insulin resistance on a high fat diet, and we provide extensive RNA profiling to illuminate potential mechanistic insights into the muscle-specific role of aB-crystallin/HspB2. Overall design: Hind limb muscle mRNA profiles of wild type and aB-crystallin/HspB2 knock mice exposed to either normal chow or high fat diets using RNAseq analysis

Description
IL-4 plays an important role in the induction of Th2 and Th9 cells as well as in the inhibition of Th1 cell generation. We herein show that a combination of IL-4 and TGFbeta augment the development of Th1 cells that express CD103 (CD103+ Th1 cells) if IFNgamma is present. The T-box containing transcription factor, eomesodermin (Eomes) is preferentially expressed in CD103+ Th1 cells, and is involved in IFNgamma production. The induction of T-bet during early T cell activation is essential for the formation of the active chromatin at both the Eomes and IFNgamma gene loci. TGFbeta is required for the induction of Eomes and CD103, as well as the inhibition of Th2 cytokine expression. In addition, IL-4 induces Eomes transcription through activation of the Stat6 signaling pathway. IFNgamma-producing CD103+ Th1 cells are detected in the IEL of normal mice, and their numbers significantly decrease in Tbet- and Stat6-deficient mice. These results represent the first molecular mechanism of IL-4/TGFbeta-dependent augmentation of Th1 cell generation, and raise the possibility that IL-4 and TGFbeta may simultaneously enhance the Th1 cell-mediated immune responses under certain cytokine conditions.
