Project description:The purpose of this study is to comprehensively elucidate the role of nitric oxide and nitric oxide synthase isoforms in pulmonary emphysema using cap analysis of gene expression (CAGE) sequencing.
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.

Project description:The goal of this study was to measure the effects of nitric oxide exposure (using DETA NONOate as a nitric oxide donor) on transcription in Caulobacter.
Project description:RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of nitric oxide-releasing acetylsalicyclic acid may prevent colorectal cancer.
PURPOSE: This randomized phase I trial is studying the side effects and best dose of nitric oxide-releasing acetylsalicyclic acid in preventing colorectal cancer in patients at high risk of colorectal cancer.
Project description:To analyze gene expression pattern in response to nitric oxde in Saccharomyces cerevisiae, we performed microarray analysis using yeast cells treated with a nitric oxide donor S-nitroso-N-acetyl-DL-penicillamine (SNAP). S. cerevisiae S288c strain was cultured in synthetic dextrose (SD) minimal medium up to log phase (OD600 = 1), and then treated with 100 micro molar of SNAP for 10, 30, or 60 min. After treatment with SNAP, cells were disrupted adn total RNA was extracted. We commissioned following experiments to BIO MATRIX RESEARCH Inc. Nitric oxide-induced gene expression in S. cerevisiae was measured at 10, 30, or 60 minutes after exposure to 100 micro molar of nitric oxide donor SNAP.
