Project description:Purpose: The aim of this study is to analyse and compare the differentially expressed genes between nitric oxide treated and thalidomide treated chick embryos Methods: The trancriptome sequencing was performed using Illumina HiSeq 2500 ® platform. The sequence reads were aligned to the reference genome of chicken (Galgal4) downloaded from Ensembl Release 75 database. Alignment was performed using TopHat (v2.0.8) program to the Ensembl Release 75 gene model of chicken with default parameter settings. After alignment, Cuffdiff (v2.2.0) program was used for performing differential expression analysis. Pathway analysis of differentially expressed genes was performed using DAVID program. Heat maps were constructed using R package software 3.1.0.
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. Untreated Caulobacter crescentus were grown to a density of 0.3 (at OD660) in PYE medium (pH 7) in rolled culture tubes. DETA-NONOate treated Caulobacter crescentus were grown to a density of 0.3 (at OD660), and then treated with 100 mM DETA NONOate for 30 minutes.

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: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.
