Description
Gene expression along the crypt-villus (C-V) axis was analyzed using cryostat sectioning to isolate fractions representing the crypts (bottom) and villus tops (top). These fractions were used for analyzing gene expression in iron replete Wistar rats (++), iron deficient Wistar rats (low iron), and in iron deficient Wistar rats fed iron for 3 and 6 days (iron-fed). Differences were observed between the crypts and villus tops in the expression of genes associated with Wnt and BNP signaling, cell proliferation and apoptosis, lipid and iron transport and metabolism. Gene expression in villus crypts and tops was also compared between Wistar and Belgrade rats (bb) and Belgrade rats fed iron (iron-fed) particularly as related to iron absorption and metabolism to define the affects of the mutation in DMT1 in the Belgrade rat on the expression of genes related to iron absorption and metabolism and the response to iron feeding.

- Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Duchenne muscular dystrophy (DMD) is an incurable neuromuscular degenerative disease, caused by a mutation in the dystrophin gene. Mdx mice recapitulate DMD features. Here we show that injection of wild-type (WT) embryonic stem cells (ESCs) into mdx blastocysts produces mice with improved pathology. A small fraction of WT ESCs incorporates into the mdx mouse nonuniformly to upregulate protein levels of dystrophin in the skeletal muscle. The chimeric muscle shows reduced regeneration and restores dystrobrevin, a dystrophin-related protein, in areas with high and with low dystrophin content. WT ESC injection also normalizes the amount of fat, a tissue that does not express dystrophin. ESC injection without dystrophin does not prevent the appearance of phenotypes in the skeletal muscle or in the fat. Thus, dystrophin supplied by the ESCs reverses disease in mdx mice globally.

Blastocyst injection of wild type embryonic stem cells induces global corrections in mdx mice.

Description
Dusp5 regulates ERK phosporylation following IL-33 receptor ligation in cultured eosinophils. Dusp5 deficient eosinophils show increased ERK phosphorylation, and as a result are less apoptotic. Since ERK stimulation results in downstream activation of transcription factors, we are utilizing a microarray approach to find alterations in gene expression to uncover potential mechanisms for increased cell survival.
Publication Title
Dusp5 negatively regulates IL-33-mediated eosinophil survival and function.

Description
Delineating the molecular basis of individual differences in the stress response is critical to understanding the pathophysiology and treatment of posttraumatic stress disorder (PTSD). In this study, 7 d after predator-scent-stress (PSS) exposure, male and female rats were classified into vulnerable (i.e., PTSD-like) and resilient (i.e.,minimally affected) phenotypes on the basis of their performance on a variety of behavioral measures. Genome-wide expression profiling in blood and two limbic brain regions (amygdala and hippocampus), followed by quantitative PCR validation, was performed in these two groups of animals, as well as in an unexposed control group. Differentially expressed genes were identified in blood and brain associated with PSS-exposure and with distinct behavioral profiles postexposure. There was a small but significant between-tissue overlap (421%) for the genes associated with exposure-related individual differences, indicating convergent gene expression in both sexes. To uncover convergent signaling pathways across tissue and sex, upstream activated/deactivated transcription factorswere first predicted for each tissue and then the respective pathways were identified. Glucocorticoid receptor (GR) signaling was the only convergent pathway associatedwith individual differences when using the most stringent statistical threshold.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
To identify individual genes with potential diagnostic and therapeutic utilities in lung cancer, we performed gene expression profiling out of a broad coverage of human transcriptome using clinical patient tissues. Six RNA samples extracted from five cancerous tissues and one normal control were subjected to Affymetrix gene array analysis using Human Exon 1.0 ST Array. Data were further processed using Expression Console and Transcriptome Analysis Console softwares. Both core-gene expression analysis and extended-gene expression analysis were performed to discover significantly regulated genes associated with lung cancer progression.
