Description
We report the effects of Rapamycin treatment on the transcriptome of normal human dermal fibroblasts isolated from foreskin (designated 2DD). We sequenced mRNA from 2 replicates of proliferative (PRO) quiescent (QUI, serum starved) or treated with 500nM Rapamycin for 5 days (RAP). Comparative analyses with PRO transcripts a baseline indicate that genes that changed expression from Rapamycin treated fibroblasts are significantly different from those of quiescence cells. Rapamycin treated cells showed a significant enrichment for cytokines from the Il-6 cascade. Overall design: Examination of mRNAs from proliferative, quiescent (serum starvation) and Rapamycin (5oonM, 5days) treated 2DD normal human dermal/foreskin fibroblasts.

Description
Heterogeneity in pluripotent cells marks a metastable state where cells may drift between native and lineage-primed populations. While the role for these heterogeneities are unclear, they may reflect the dynamic equilibriums of signaling networks and have a direct effect on differentiation potentialities. Here, we report the role of the cell cycle in establishing heterogeneity of human pluripotent stem cells. By utilizing the FUCCI cell cycle indicator system coupled to fluorescent activated cell sorting (FACS), we have uncovered that the cell cycle drives heterogeneity at the epigenetic, transcriptional and post-transcriptional levels. Our data show widespread dynamics in 5-hydroxymethylcytosine (5hmC) during the cell cycle. Furthermore, transcript profiling by RNA-sequencing identified >500 genes that were cell cycle-regulated, of which the largest cohort of genes were transcriptional regulators. In sum, we demonstrate the role of the cell cycle in coordinating cellular transitions between metastable states in pluripotent stem cells. Overall design: mRNA sequencing of the cell cycle phases; early & late G1, S and G2/S from human ES cells in triplicate.

Affymetrix Pseudomonas aeruginosa Array (paeg1a)
Description
The anaerobic metabolism of the opportunistic pathogen Pseudomonas aeruginosa is important for growth and survival during persistent infections. The two Fnr-type transcription factors Anr and Dnr regulate different parts of the underlying network. Both are proposed to bind to a non-distinguishable DNA sequence named Anr box.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
This dataset contains microarray data from normal controls (aged 20-99 yrs) and Alzheimer's disease cases, from 4 brain regions: hippocampus, entorhinal cortex, superior frontal cortex, post-central gyrus. Changes in expression of synaptic and immune related genes were analyzed, investigating age-related changes and AD-related changes, and region-specific patterns of change.

Description
DNA methylation is essential for mammalian development and plays crucial roles in a variety of biological processes. The DNA methyltransferase Dnmt1 serves to maintain parental cell methylation patterns on daughter DNA strands in mitotic cells, however, the precise role of Dnmt1 in regulation of quiescent adult stem cells is not known.

Description
In order to find a relationship between gene expression of blood and brain in Rett Syndrome (RTT), we performed RNA sequencing on from cerebella and blood of 7 week-old male Mecp2-null mice (a model of RTT) and WT controls. Overall design: Transcriptional profiles were generated from cerebellum and blood of 3 Mecp2-null and 3 WT 7 week-old male mice, by RNAseq performed on an Illumina HiSeq 2000 System, generating approximately 60 million 2x75bp paired-end reads/sample. Blood and cerebellum samples originate from the same animal

Description
We sequenced mRNA extracted from heads of a D. melanogaster population that was sedated with a stream of ethanol saturated vapor, 30 minutes before RNA extraction; and from an age-matched untreated control group. Differential gene expression between the two groups was calculated and reported. Overall design: Examination of mRNA levels in heads of D. melanogaster adult females after ethanol exposure was performed using next generation sequencing (NGS) technology.

- Affymetrix C. elegans Genome Array (celegans)
Description
Very little is known about how animals discriminate pathogens from innocuous microbes. To address this question, we examined infection-response gene induction in the nematode Caenorhabditis elegans. We focused on genes that are induced in C. elegans by infection with the bacterial pathogen Pseudomonas aeruginosa, but are not induced by an isogenic attenuated gacA mutant. Most of these genes are induced independently of known immunity pathways. We generated a GFP reporter for one of these genes, infection response gene 1 (irg-1), which is induced strongly by wild-type P. aeruginosa strain PA14, but not by other C. elegans pathogens or by other wild-type P. aeruginosa strains that are weakly pathogenic to C. elegans. To identify components of the pathway that induces irg-1 in response to infection, we performed an RNA interference screen of C. elegans transcription factors. This screen identified zip-2, a bZIP transcription factor that is required for inducing irg-1, as well as several other genes, and is important for defense against infection by P. aeruginosa. These data indicate that zip-2 is part of a specialized pathogen response pathway that is induced by virulent strains of P. aeruginosa and provides defense against this pathogen.
