Description
Rationale. Lung inflammation in premature infants contributes to development of bronchopulmonary dysplasia (BPD), a chronic lung disease with long-term sequelae. Pilot studies administering budesonide suspended in surfactant have found reduced BPD without apparent adverse effects as occur with systemic dexamethasone therapy. Objectives. To determine effects of budesonide on differential genes expression in human fetal lung Overall design: Methods. We prepared RNA from 3 samples of human fetal lung at 23 weeks gestation before (preculture, PC) and after 4 days culture as explants with (Bud) or without (Way) budesonide (30 nM) and performed RNAseq on the 9 samples.

Description
To gain comprehensive insight into the OGT-dependent transcriptional program in Treg cells, we performed RNA-sequencing of isolated YFP+ Treg cells from Foxp3YFP-Cre/wtOgtwt/fl and healthy Foxp3YFP-Cre/wtOgtfl/fl females to avoid secondary changes in gene expression caused by inflammation. We were able to identify 269 differentially expressed genes including 154 downregulated and 115 upregulated with p values less than 0.01, OGT-deficient Treg cells had impaired suppressive function and attenuated IL2/STAT5 signaling pathway. Overall design: Examination of the function of OGT in Treg cells

Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Retrograde signaling from axon to soma activates intrinsic regeneration mechanisms in lesioned peripheral sensory neurons; however, the links between axonal injury signaling and the cell body response are not well understood. Here, we used phosphoproteomics and microarrays to implicate ~900 phosphoproteins in retrograde injury signaling in rat sciatic nerve axons in vivo and ~4500 transcripts in the in vivo response to injury in the dorsal root ganglia. Computational analyses of these data sets identified ~400 redundant axonal signaling networks connected to 39 transcription factors implicated in the sensory neuron response to axonal injury. Experimental perturbation of individual overrepresented signaling hub proteins, including Abl, AKT, p38, and protein kinase C, affected neurite outgrowth in sensory neurons. Paradoxically, however, combined perturbation of Abl together with other hub proteins had a reduced effect relative to perturbation of individual proteins. Our data indicate that nerve injury responses are controlled by multiple regulatory components, and suggest that network redundancies provide robustness to the injury response

Description
Trypanosoma cruzi is an obligate intracellular protozoan parasite that causes human Chagas disease, a leading cause of heart failure in Latin America. Using Affymetrix oligonucleotide arrays we screened phenotypically diverse human cells (foreskin fibroblasts, microvascular endothelial cells and vascular smooth muscle cells) for a common transcriptional response signature to T. cruzi. A common feature was a prominent type I interferon response, indicative of a secondary response to secreted cytokines. Using transwell plates to distinguish cytokine-dependent and -independent gene expression profiles in T. cruzi-infected cells, a core cytokine-independent response was identified in fibroblasts and endothelial cells that featured metabolic and signaling pathways involved in cell proliferation, amino acid catabolism and response to wounding. Significant downregulation of genes involved in mitotic cell cycle and cell division predicted that T. cruzi infection impedes cell cycle progression in the host cell.

Description
Mechanical Stimuli are arguably the most important aetiolgical factors in osteoarthritis (OA) development. Not only do we see disease arising from joints where the cartilage has sustained direct (e.g. intraarticular fracture) or indirect (e.g. meniscal injury) trauma, but mechanical factors are considered, at least partly, to explain the disease associations with aging and obesity. It is now well established that OA is not simply due to repeated wear and tear, leading to attrition of the articular surfaces, but that it requires activation of a number of inflammatory genes, which drive catabolic protease activity in the joint. These enzymes lead to breakdown of the major extracellular matrix components of cartilage, namely type II collagen, and the proteoglycan, aggrecan. Although it is unclear precisely which enzymes are responsible for matrix breakdown in human OA, Glasson et al showed that deletion of the aggrecan degrading enzyme, ADAMTS5 substantially protected the joint from surgically induced murine OA suggesting that it is a major aggrecanase in the mouse.

Description
In this study, investigators recruited the largest reported cohort of tolerant kidney transplant recipients who maintained their graft after ceasing to take their immunosuppression drug, and compared this cohort to subjects with stable allograft function while on immunosuppression and healthy non transplated, controls. Using gene expression studies, they identified genetic markers that are strong candidates for predicting kidney transplant candidates who may benefit from minimization or withdrawl of immunosuppression.

Description
Crystal cells are one of the 3 Drosophila blood cell lineages and represent less than 5% of the total hemocytes in wild type larvae. There development is notably controlled by mlf (myeloid leukemia factor), which regulate their number by stabilising the lineage-specific transcription factor Lozenge. To gain insight into the biology of this blood cell lineage and its regulation by mlf, we established the gene expression profile of the circulating crystal cells in wildtype and mlf mutant third instar larvae. This study provides a rich source of information to further characterise crystal cell function and regulation. In addition our data show that mlf is a major regulator of crystal cell gene expression programm and that mlf mutation leads to the accumulation of misdifferentiated crystal cells. Overall design: RNA expression profiles of sorted lz-GAL4,UAS-GFP+ circulating blood cells from wild type and mlf-/- third instar Drosophila larvae were generated by deep sequencing, in triplicate, using Illumina HiSeq2500 sequencing platform.
