TranscriptomicsCOMPARATIVE SYSTEMS TOXICOLOGY ANALYSIS OF CIGARETTE SMOKE AND AEROSOL FROM A CANDIDATE MODIFIED RISK TOBACCO PRODUCT IN ORGANOTYPIC HUMAN GINGIVAL EPITHELIAL CULTURES: A 3-DAY REPEATED EXPOSURE STUDY.
Smoking is one of the major lifestyle-related risk factors for periodontal diseases. Modified risk tobacco products (MRTP) offer a promising alternative in the harm reduction strategy for adult smokers unable to quit. Using a systems toxicology approach, we investigated and compared the exposure eff...

TranscriptomicsA Universal RNA Polymerase II CTD Cycle Is Orchestrated by Complex Interplays Between Kinase, Phosphatase and Isomerase Enzymes Along Genes
Transcription by RNA polymerase II (RNAPII) is coupled to mRNA processing and chromatin modifications via the C-terminal domain (CTD) of its largest subunit, consisting of multiple repeats of the heptapeptide YSPTSPS. Pioneering studies showed that CTD serines are differentially phosphorylated along...

TranscriptomicsExpression data from maternally inflamed and Dap12-mutant microglia at E17.5.
Microglia colonize the brain parenchyma at early stages of development and accumulate in specific regions where they actively participate in cell death, angiogenesis, neurogenesis and synapse elimination. A recurring feature of embryonic microglial distribution is their association with developing a...

GenomicsE2F7 represses a transcriptional network of oscillating cell cycle genes to control S-phase progression.
E2F transcription factors are known to be important for timely activation of G1/S and G2/M genes required for cell cycle progression, but transcriptional mechanisms for deactivation of cell cycle regulated genes are unknown. Here, we show that E2F7 is highly expressed during mid to late S-phase, occ...

TranscriptomicsChromatin immunoprecipitation of human cell lines with oestrogen receptor (ER), the E2F transcription factor 4 (E2F4),
The Goal of the experiment was to validate the predicted regulatory modules identified by an algorithm.For this we took advantage of the the genome-wide location analysis technique (or ?ChIP/chip?). We selected modules predicted to be bound by the estrogen receptor (ER), the E2F transcription factor...

TranscriptomicsDSIF and RNA polymerase II CTD Phosphorylation Coordinate the Recruitment of Rpd3S to Actively Transcribed Genes
Histone deacetylase Rpd3 is part of two distinct complexes: the large (Rpd3L) and small (Rpd3S) complexes. While Rpd3L targets specific promoters for gene repression, Rpd3S is recruited to ORFs to deacetylate histones in the wake of RNA polymerase II, to prevent cryptic initiation within genes. Meth...

TranscriptomicsIN VITRO ASSESSMENT OF ACUTE EXPOSURE OF THS2.2 AEROSOL ON ORGANOTYPIC ACUTE HUMAN BRONCHIAL TISSUE CULTURES
In vitro toxicology approaches have evolved, from a focus on the molecular changes within a cell to understanding of toxicity-related mechanisms that simulate the in vivo environment. The recent development of three dimensional (3-D) organotypic nasal epithelial culture models offer a physiologicall...

TranscriptomicsHuman splenic marginal zone precursors (MZP) differentiation into marginal zone B cells (MZB)through a Notch2 signalling pathway
RNA microarray profiling analysis was performed on different ex-vivo human splenic B cell subsets (M-^SNaM-oveM-^T, marginal zone precursors or M-^SMZPM-^T, marginal zone B cells orM-^T MZBM-^T, M-^SMTG+CD45+M-^T cells) and on M-^Sp27M-^T cells, corresponding to the fraction of MZP cells that diff...
