Description
Transcriptomic analysis of gene expression during the differentiation of cell suspension cultures into tracheary elements using the biological system published by Pesquet et al., Current Biology (2010): tracheary element differentiation was triggered by externally supplying hormone-free habituated cell suspension cultures of Arabidopsis thaliana Col-0 with auxin, cytokinin and epibrassinolides; RNA samples extracted from 3 independent time-courses every 12h from 0h to 4 days were analyzed using ATH1 Arabidopsis Affymetrix micro-array

Description
The inflammatory response of preterm infants' intestine underlines its inability to respond to hemodynamic stress, microbes and nutrients. Recent evidence suggests that exogenous epidermal growth factor (EGF) exerts a therapeutic influence on neonatal enteropathies. However, the molecular mechanisms underlying the beneficial effects of EGF remain to be clarified. The purpose of this study was to evaluate the impact of EGF on the gene expression profiles of the developing human small and large intestine at mid-gestation in serum-free organ cultures using Illumina microarrays.

Description
Necrotizing enterocolitis (NEC) is the most frequent life-threatening gastrointestinal disease experienced by premature infant occuring in neonatal intensive care units. NEC is associated with severe intestinal inflammation, intestinal perforation leading to mortality. The challenge for neonatologists is to detect early clinical manifestations of NEC. Therefore, one of the strategies to prevent or treat NEC would be to develop an early diagnostic tool allowing identification of preterm infants either at risk of developing NEC or at the onset of the disease. Illumina’s deep sequencing technology (RNA-seq) was used to establish the gene expression profile between resected ileal healthy preterm (control, n=5) and NEC diagnosed preterm infant (NEC, n=9) and analyzed by IPA Core analysis system. IPA analysis indicated that the most significant functional pathways overrepresented in NEC neonates were associated with innate immune functions, such as altered T and B cell signaling, B cell development, and the role of pattern recognition receptors in recognition of bacteria and viruses. Among genes that were strongly modulated in NEC neonates, we observed a high degree of similarity with those linked to the development of IBD. By comparing gene expression patterns between NEC and Crohn’s disease, we identified several new potential protein targets for helping to predict and/or diagnose NEC in preterm infant. Gene expression profile revealed an uncontrolled innate immune response in the intestine of NEC neonates. Moreover, comparative analysis between NEC and Crohn’s disease evidenced high degree of similarity between these two inflammatory diseases and allowed us to identify several new potential NEC biomarkers. Overall design: Illumina’s deep sequencing technology (RNA-seq) was used to establish the gene expression profile between resected ileal healthy preterm (control, n=5) and NEC diagnosed preterm infant (NEC, n=9)

Description
Allergic diseases correspond to a broad range of hypersensitivity reactions, often occurring as co-morbidities. Investigation of the molecular basis of allergy is a challenge because of its highly heterogeneous nature. We combined large-scale and high-throughput gene expression technology and systems biology approaches to retrieve relevant biomarkers and signalling pathways.

Description
Mesenchymal stem cells (MSCs) And osteolineage cells contribute to the hematopoietic stem cell (HSC) Niche in the bone marrow of long bones. However, Their developmental relationships remain unclear. Here we demonstrate that different MSC populations in the developing marrow of long bones have distinct functions. Proliferative mesoderm-derived nestin- MSCs participate in fetal skeletogenesis, And lose MSC activity soon after birth. In contrast, Quiescent neural-crest-derived nestin+ Cells in the same bones preserve MSC activity, But do not generate fetal chondrocytes. Instead, They differentiate into HSC-niche-forming MSCs, Helping to establish the HSC niche by secreting Cxcl12. Perineural migration of these cells to the bone marrow requires the ErbB3 receptor. The neonatal Nestin-GFP+ PDGFR- Cell population also contains Schwann-cell precursors, But does not comprise mature Schwann cells. Thus, In the developing bone marrow HSC-niche-forming MSCs share a common origin with sympathetic peripheral neurons and glial cells, And ontogenically distinct MSCs have non-overlapping functions in endochondrogenesis and HSC niche formation. Overall design: Total RNA was isolated from small numbers of FACS sorted stromal cells, obtained from neonatal Nes-Gfp bone marrow preparations (2 biological replicates). Each independent set of samples was obtained from pooled skeletal elements (long bones and sterna) form multiple littermates.

Description
The Cytoplasmic Polyadenylation Element Binding (CPEB)-family of RNA-binding proteins regulates pre-mRNA processing and translation of CPE-containing mRNAs in early embryonic development and synaptic activity. However, the specific functions of each CPEB in the adult organism are poorly understood. Here we show that CPEB4 is required to suppress high fat diet- and aging-induced endoplasmic reticulum (ER) stress, and its subsequent hepatic steatosis. Stress-activated expression of CPEB4 in the liver is controlled through a double layer of regulation. First, Cpeb4 is transcriptionally regulated by the circadian clock and then, its mRNA translation is regulated by the Unfolded Protein Response (UPR) through the upstream Open Reading Frames (uORFs) present in its 5’ UTR. Thus, CPEB4 is synthesized only upon ER-stress but the amplitude of the induction is circadian. In turn, CPEB4 activates a second wave of UPR-translation required to maintain ER and mitochondrial homeostasis. Our results suggest that combined transcriptional and translational regulation of CPEB4 generates a “circadian mediator”, which?coordinates the hepatic UPR activity with periods of high ER protein-folding demand preventing non-alcoholic fatty liver disease (NAFLD). Overall design: mRNA profiles of total liver RNA and liver ER-associated RNA from WT and CPEB4-KO mice
