Transcriptional responses to nitric oxide are widescale and source-dependent (calcium)

Project description:The transcriptomic effects of nitric oxide (NO) have been widely studied across phylogeny. However, while gene expression is canonically altered by NO, general principles have not emerged. Here, we characterize genetic regulation within a single cell type after exposure to NO derived from endogenous or synthetic donor compounds or produced by three different NO synthase (NOS) isoforms under basal and activated conditions. Using RNAseq, we uncover distinct, source-dependent effects of NO on as many as ~10,000 genes mediated largely by S-nitrosylation. NOS enzymes and NO donors each generated unique transcriptional responses. Our data reveal non-overlapping transcriptional responses to NO that are likely mediated by distinct effectors and enzymes and highlight that NO-treated cell systems may undergo a dramatic and widespread transcriptional response.

Transcriptome response to nitric oxide in Pseudomonas aeruginosa

Project description:DNA microarray analysis was employed to investigate the transcriptome response to nitric oxide in Pseudomonas aeruginosa. We focused on the role played by the nitric oxide-response regulators DNR and FhpR and an oxygen-response regulator ANR in the response. The transcriptome profiles of the P. aeruginosa strains before and after exposure to nitric oxide under the microaerobic conditions were analyzed. Wild type, its anr, dnr, and fhpR mutants, and the anr mutant that express dnr were used for the analyses. Pseudomonas aeruginosa wild type (PAO1ut), anr mutant (RManr), dnr mutant (RMdnr), anr mutant that constitutively expresses DNR (RManrEXdnr), and fhpR mutant (PDM2665) were cultivated microaerobically in LB in 1-liter jar fermenter. When optical density at 600 nm reached 0.3, nitric oxide-saturated water was added to the medium (final nitric oxide concentration was 20 micro-M). RNA was isolated from a 10 ml aliquot of the culture prior to the addition of nitric oxide and at 5 min after the addition. The experiment was performed in duplicate independent cultures.

Nitric oxide-dependent changes in Schistosoma mansoni gene expression

Project description:Nitric oxide (NO) is a gaseous intercellular signaling molecule that also plays a role in host-parasite relations. NO acts rapidly, either via regulation of soluble guanylate cyclase, or by direct interactions with enzymes and other proteins, and has also been shown to have effects on gene expression. Here, we use SAGE (Serial Analysis of Gene Expression) to identify NO-responsive changes in gene expression in Schistosoma mansoni following a 3 hour exposure to sodium nitroprusside, an NO donor. Overall, these results indicate that NO does not rapidly induce large-scale changes in schistosome gene expression, but that expression of particular genes of interest appear to respond to NO. Keywords: Schistosoma, SAGE, NOS, nitric oxide, gene expression
