View SamplesTo study the effects of previous exposure to mechanical ventilation may modify the development of Ventilator-induced lung injury, preconditioning was induced by low-pressure ventilation for 90 minutes. After 1 week, intact (sham) and preconditioned mice were sacrificed, the lungs extracted and gene expression measured in order to identify differences responsible for the observed tolerance to ventilator-induced lung injury observed in preconditioned animals.

View SamplesThe whole blood was collected pre-treatment from rheumatoid arthritis patients starting the anti_TNF therapy. All patients were nave to anti_TNFs. The disease activity was measured using the DAS28 score at the pre-treatment visit1 (DAS28_v1) and 14 weeks after treatment visit3 (DAS28_v3). The response to the therapy was evaluated using the EULAR [European League Against Rheumatism] definition of the response. The objective of the data analysis was to identify gene expression coorelating with response as well as to identify genes that differentiate responders versus non-responders pre-treatment. The results of this investigation identified 8 trainscripts that predict responders vs. non-responders with 89% accuracy.

View SamplesThe heat shock response (HSR) is a mechanism to cope with proteotoxic stress by inducing the expression of molecular chaperones and other heat shock response genes. The HSR is evolutionarily well conserved and has been widely studied in bacteria, cell lines and lower eukaryotic model organisms. However, mechanistic insights into the HSR in higher eukaryotes, in particular in mammals, are limited. We have developed an in vivo heat shock protocol to analyze the HSR in mice and dissected heat shock factor 1 (HSF1)-dependent and -independent pathways. Whilst the induction of proteostasis-related genes was dependent on HSF1, the regulation of circadian function related genes, indicating that the circadian clock oscillators have been reset, was independent of its presence. Furthermore, we demonstrate that the in vivo HSR is impaired in mouse models of Huntington's disease but we were unable to corroborate the general repression of transcription after a heat shock found in lower eukaryotes. Overall design: RNA-Seq was performed on mRNA isolated from quadriceps femoris muscle of 24 mice. These mice were of wild type, R6/2, and Hsf1-/- genotypes. Two mice of each genotype were tested in four conditions: (1) heat shock, (2) control heat shock, (3) HSP90 inhibition (NVP-HSP990), and (4) HSP90 inhibition vehicle.

View SamplesPhosphorylation of histone H3 at Serine 10 emerges as a mechanism increasing chromatin accessibility of the transcription factor NF-kB for a particular set of immune genes. Here we report that a bacterial pathogen uses this strategy to shape the transcriptional response of infected host cells. We identify the Shigella flexneri type III protein effector OspF as a Dual Specific Phosphatase. OspF dephosphorylates MAP kinases within the nucleus impairing histone H3 phosphorylation at Serine 10 in a gene-specific manner. Therefore, OspF reprograms the transcriptional response for inactivation of a subset of NF-kB responsive genes. This regulation leads to repression of polymorphonuclear leukocytes recruitment in infected tissues. Thus, pathogens have evolved the ability to precisely modulate host cell epigenetic information as a strategy to repress innate immunity.
An injected bacterial effector targets chromatin access for transcription factor NF-kappaB to alter transcription of host genes involved in immune responses.
