- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
HESC-H9 and iPSC lines 3.5, 3.6 and 3.12 were analyzed using Affymetrix microarray before and after Definitive Endoderm (DE) formation. DE was induced using the ActivinA differentiation protocol described by D'Amour et al., 2006 (PMID: 16258519) Clustering analysis of transcripts that were differentially regulated during DE formation indicated that iPSC lines 3.5 and 3.12 differentiate in manner that is highly similar to HESC-H9 cells iPSC line 3.6 had a more divergent transcriptional profile.

- Affymetrix Rat Expression 230A Array (rae230a)
Description
The Dahl salt-sensitive (S) rat model develops chronic hypertensive disease when fed a high salt diet that ultimately results in renal and heart failure, as well as prevalent cerebrovascular pathologies. Phenotypic changes in the cerebral vasculature are preceded by changes in gene expression, and evidence supports a role for extracellular signal-regulated kinase 1/2 (ERK1/2) in vascular cell proliferation, yet little is known regarding ERK1/2 regulated gene transcription in cerebrovascular smooth muscle during hypertension. Findings presented here support the hypothesis that salt-induced hypertensive disease results in upregulation of ERK1/2 activity and ERK1/2-regulated genes that promote remodeling in cerebral resistance arteries. Dahl S rats were fed either a 0.4% NaCl (low salt, LS) or 8% NaCl (high salt, HS) diet until evidence of left ventricular dysfunction. Gene expression profiling using oligonucleotide array analysis detected a significant fold-change of 1.5 or greater in 133 out of 15,923 genes examined. Mitogen-activated protein kinase (MAPK)-regulated genes were overrepresented and provided a link to genes involved in proliferation and extracellular matrix signaling including plasminogen activator inhibitor I (PAI-1), osteopontin (OPN) and junB. These data suggests that salt induced hypertensive disease promotes hyperplasia and changes in matricellular genes that are likely important in vascular remodeling.

- Affymetrix Xenopus laevis Genome 2.0 Array (xlaevis2)
Description
Exostosin 1 (Ext1) is a glycosyltransferase involved in the biosynthesis of the extracellular matrix Heparan Sulfate Proteoglycan (HSPG). Knockdown of Ext1 caused gastrulation defects and formation of an abnormal body axis. Since ext1 has been implicated as an indirect contributor to multiple signaling pathways in vertebrate development, microarray was used to identify genes expressed in gastrulae that would be affected by a reduction in ext1 expression. Microarray-based comparisons of gene expression in control vs. Ext1 MO embryos showed that Ext1 is involved in regulating genes that are related to metabolic process, development and signaling pathways. Half of the hits from the microarray are uncharacterized genes. Approximately forty-five percent of genes are related to metabolic process and thirty percent of genes are belonged to signaling and developmental process categories. Ten percent of each up-regulated and down-regulated gene set is predicted to function in establishment of localization by GO, which is consistent with EXT1 being involved in the movement of extracellular substances. The transcription factors or signaling protein, Isl1, Pitx2, TBX5A, Wnt5A, Wnt7A, WT1, Pax3, Wnt1, and Xbra were identified as Ext1 regulated genes. This analysis investigating the role of Ext1 during gastrulation and provide the information that EXT1 plays an important role in Xenopus early development.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
RNA from 5 mice with postdevelopmental knockout of myostatin and 5 mice with normal myostatin expression was analyzed with comprehensive oligonucleotide microarrays. Myostatin depletion affected the expression of several hundred genes at nominal P < 0.01, but fewer than a hundred effects were statistically significant according to a more stringent criterion (false discovery rate < 5%). Most of the effects were less than 1.5-fold in magnitude. In contrast to previously-reported effects of constitutive myostatin knockout, postdevelopmental knockout did not downregulate expression of genes encoding slow isoforms of contractile proteins or genes encoding proteins involved in energy metabolism. Several collagen genes were expressed at lower levels in the myostatin-deficient muscles, and this led to reduced tissue collagen levels as reflected by hydroxyproline content. Myostatin knockout tended to down-regulate the expression of sets of genes with promoter motifs for Smad3, Smad4, myogenin, NF-B, serum response factor, and numerous other transcription factors. Main conclusions: in mature muscle, myostatin is a key transcriptional regulator of collagen genes, but not genes encoding contractile proteins or genes encoding proteins involved in energy metabolism.
