TranscriptomicsRNA-seq of different tissues from wild-type and C/EBPα ΔuORF mutant African turquoise killifish Nothobranchius furzeri
The transcription factor CCAAT/enhancer binding protein alpha (C/EBPα) regulates cell differentiation, proliferation, and function in various tissues, including the liver, adipose tissue, skin, lung, and hematopoietic system. Studies in rats, mice, humans, and chickens have shown that CEBPA mRNA und...

TranscriptomicsPBMC response to B. pertussis filamentous hemagglutinin stimulation in vitro
Filamentous hemagglutinin (FHA), Bordetella pertussis' key adhesin, is both present at the cell surface and released in the extracellular milieu. To comprehend the role free FHA plays in the pathogenic process, we analyzed the global transcriptional changes in human peripheral blood mononuclear cell...

TranscriptomicsDifferential production of Type I IFN determines the reciprocal levels of IL-10 and proinflammatory cytokines produced by C57BL/6 and BALB/c macrophages
Pattern recognition receptors (PRR) detect microbial products and induce cytokines which shape the immunological response. Interleukin-12 (IL-12), tumor necrosis factor alpha (TNF-α) and IL-1β are proinflammatory cytokines which can be essential for resistance against infection, but if produced at...

TranscriptomicsTranscription profiling of rat fibroblasts transformed with HRAS and treated with the demethylating agent 5-aza-2-deoxycytidine
Silencing of gene expression by methylation of CpG islands in regulatory elements is frequently observed in cancer. However, an influence of the most common oncogenic signalling pathways onto DNA methylation has not yet been investigated thoroughly. To address this issue, we identified genes suppres...

TranscriptomicsChromatin modifications induced by PML-RARalpha repress critical targets in leukemogenesis as analyzed by ChIP-Chip.
A global view of PML-RAR? transcriptional functions was obtained by genome-wide binding and chromatin modification analyses, combined with genome wide expression data. Complete Abstract: The translocation t(15;17) generates the chimeric PML-RAR? transcription factor that is the initiating event of ...

TranscriptomicsTranscription profiling of procyclic Trypanosoma brucei cultured at 27oC or under heat shock stress conditions at 41oC
Procyclic trypanosomes (strain 427 lister) were grown in culture under standard conditions at 27ºC in SDM79 medium with 10% foetal bovine serume (Brun and Schnenberger, 1979), in a gazed incubator (5% CO2). Logarithmically growing procyclic cells (at about 5*10^6 cells/ml, at 27°C) were added to o...

TranscriptomicsTranscription profiling of human head and neck squamous cell carcinomas that are positive or negative for Human Papilloma Virus
Introduction: Human Papilloma Virus (HPV) is associated with a subset of head and neck squamous cell carcinoma (HNSCC), between 15% and 35% of HNSCC harboring HPV, almost exclusively of subtype 16. Demographic and exposure differences between HPV-positive (+) and negative (-) HNSCCs suggest that HPV...

TranscriptomicsDpiA overexpression
The dpiA and dpiB genes of Escherichia coli, which are orthologs of genes that regulate citrate uptake and utilization in Klebsiella pneumoniae, comprise a two-component signal transduction system that can modulate the replication of and destabilize the inheritance of pSC101 and certain other plasmi...

TranscriptomicsshRNAi profiling of human MDA-MB-231 cells expressing anti-p53 (shp53) short-hairpin RNAs treated with TFGbeta or control
TGFβ ligands act as tumor suppressors in early stage tumors but are paradoxically diverted into potent prometastatic factors in advanced cancers. The molecular nature of this switch remains enigmatic. We now show that TGFβ-dependent cell migration, invasion and metastasis are empowered by mutant-p...

TranscriptomicsTranscription profiling by array of Arabidopsis roots split and grown in media with or without inorganic phosphate
Arabidopsis plants were grown in sand and supplied with full nutrient during 6 to 7 weeks in a growth chamber in controlled conditions (21/18°C day/night temperature, 60 % humidity, 8 h photoperiod). Then for the split-root experiments, the root system was washed in water to discard the sand and sep...
