Description
Hydrogen peroxide is known to promote skin keratinocyte migration, although the mechanism of action is unclear. In an attempt to identify signaling pathways regulated by hydrogen peroxide in the skin, 3 day post fertilized (dpf) zebrafish larvae (nacre strain) were treated with 3mM hydrogen peroxide for 2 hours and subjected to RNA-seq analyses. Pools of about 1000 embryos for each of three biological replicates were derived from 5 independent mating pairs and raised to larval stages until 3 dpf. All larvae were subsequently homogenized in Trizol and total RNA was extracted using a chloroform extraction protocol treated with DNAse. Messenger RNA (mRNA) was subsequently purified from total RNA using biotin-tagged poly dT oligonucleotides and streptavidin-coated magnetic beads, followed by quality control using an Agilent Technologies 2100 Bioanalyzer (values >7 were used for sequencing). The poly(A)-tailed mRNA samples were fragmented and double-stranded cDNA generated by random priming for deep sequencing studies. Overall design: 6 samples total were analyzed. 3 untreated, and 3 hydrogen peroxide treated (3mM, 2hr)

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
GM-CSF controls the development of granulocytes but little is known about the contribution of the downstream mediating transcription factor STAT5A/B. To elucidate this pathway, we generated mice lacking the Stat5a and 5b genes in blood cells. Peripheral neutrophils were decreased and administration of 5-FU and GM-CSF failed to induce granulopoiesis in Stat5a/b-mutant mice. GMPs were isolated and cultured with GM-CSF. Both the number and size of STAT5A/B-null colonies were reduced and GM-CSF-induced survival of mature STAT5A/B-null neutrophils was impaired. Time-lapse cinematography and single cell tracking of GMPs revealed that STAT5A/B-null cells were characterized by a longer generation time and an increased cell death. Gene expression profiling experiments suggested that STAT5A/B directs GM-CSF signaling through the regulation of cell survival genes.

Description
Diseases involving the distal lung alveolar epithelium include chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and lung adenocarcinoma. Accurate labeling of specific cell types is critical for determining the contribution of each to pathogenesis of these diseases. The distal lung alveolar epithelium is comprised of two cell types, alveolar epithelial type 1 (AT1) and type 2 (AT2) cells. While cell type-specific markers, most prominently surfactant protein C (SFTPC), have allowed detailed studies of AT2 cell differentiation and their roles in disease, studies of AT1 cells have been hampered by lack of genes with expression unique to AT1 cells. To address this, we performed genome-wide expression profiling of multiple rat organs alongside purified rat AT2, AT1 and in vitro differentiated AT1-like cells, resulting in identification of 54 candidate AT1 cell markers. Cross-referencing with genes upregulated in human in vitro differentiated AT1-like cells narrowed the potential list to 18 candidate genes. Testing the top four candidate genes at RNA and protein levels revealed GRAM domain 2 (GRAMD2), a protein of unknown function, as unique to AT1 cells, while SCNN1G within lung is restricted to AT1 cells. RNAseq confirmed that GRAMD2 is transcriptionally silent in human AT2 cells. Immunofluorescence of mouse alveoli verified that GRAMD2 expression is restricted to the plasma membrane of AT1 cells. These new AT1 cell-specific genes, with GRAMD2 as a leading candidate, will enhance AT1 cell isolation, investigation of alveolar epithelial cell differentiation potential, and contribution of AT1 cells to distal lung diseases. Overall design: RNAseq of purified primary human alveolar epithelial type 2 (AT2) and in vitro differentiated type 1 (AT1-like) cells.

Description
Background: Cerebral ischemia/reperfusion injury is a common secondary effect of cardiac arrest which is largely responsible for postresuscitative mortality. Therefore development of therapies which restore and protect the brain function after cardiac arrest is essential. Methylene blue (MB) has been experimentally proven neuroprotective in a porcine model of global ischemia-reperfusion in experimental cardiac arrest. However, no comprehensive analyses have been conducted at gene expression level.

Description
The ubiquitin proteasome system (UPS) is known to possess important regulatory functions in the immune response. To gain a better and first comprehensive insight into the mechanisms of remodelling of UPS related gene expression inresponse to interferon-gamma, we undertook a comparative gene expression profiling during interferon-gamma stimulation at very early time points.

Description
Mutations in the gene encoding the transcription factor forkhead box P1 or FOXP1 occur in patients with neurodevelopmental disorders, including autism. However, the function of FOXP1 in the brain remains mostly unknown. Here, we identify the gene expression program regulated by FoxP1 in both human neural cells and mouse brain and demonstrate a conserved role for FOXP1 transcriptional regulation of autism and Fragile X Mental Retardation Protein (FMRP) mediated pathways. Coexpression networks support a role for Foxp1 in neuronal activity, and we show that Foxp1 is necessary for neuronal excitability. Using a Foxp1 mouse model, we observe defects in ultrasonic vocalizations. This behavioral phenotype is reflected at the genomic level as striatal Foxp1-regulated overlap with genes known to be important in rodent vocalizations. These data support an integral role for FOXP1 in regulating signaling pathways vulnerable in developmental disorders and the specific regulation of pathways important for vocal communication. Overall design: We carried out RNA-sequencing (RNA-seq) and ChIP-sequencing of human neural progenitors cells. We carried out RNA-sequencing (RNA-seq) of mouse striatal tissue, mouse hippocampal tissue and mouse cortical tissue. For the RNA-seq, four indipendent replicates were used for the neural progenitor cells and mouse tissues. For the Chip-seq, a single neural progenitor cell line was used.
