  1. The glutathione-disrupted biofilm of clinical Pseudomonas aeruginosa strains: enhanced antibiotic affect and a novel biofilm transcriptome BioProject

    ID: PRJNA303970

    Keywords: Transcriptome or Gene expression

    Access Type: download

    dataset.description: utum. Antibiotic therapy is stymied by antibiotic resistance of the biofilm matrix, making novel anti-biofilm strategies highly desirable. Within the P. aeruginosa biofilm, the redox factor pyocyanin enhances biofilm integrity by intercalating with extracellular DNA. The antioxidant glutathione (GSH) reacts with pyocyanin to disrupt intercalation. This study investigated GSH disruption by assaying the ph...
  2. Pathways leading to phosphorylation of p450c17 and to the post-translational regulation of androgen biosynthesis ArrayExpress

    ID: E-GEOD-44311

    Description: components of the ERK1/2 and MAPK/ERK kinase (MEK)1/2 pathways, which have been implicated in the insulin resistance of PCOS, were not found in NCI-H295A cells, implying that these pathways do not participate in P450c17 phosphorylation. Treatment with various kinase inhibitors that probe the protein kinase A/phosphatidylinositol 3-kinase/Akt pathway and the calcium/calmodulin/MAPK kinase pathway had no effect on the ratio of 17,20 lyase activity to 17alpha-hydroxylase activity, appearing to eliminate these pathways as candidates leading to the phosphorylation of P450c17. Two inhibitors that target the Rho-associated, coiled-coil containing protein kinase (ROCK)/Rho pathway suppressed 17,20 lyase activity and P450c17 phosphorylation, both in NCI-H295A cells and in COS-1 cells transfected with a P450c17 expression vector. ROCK1 phosphorylated P450c17 in vitro, but that phosphorylation did not affect 17,20 lyase ...

  3. Genome-wide transcriptional response of the archaeon Thermococcus gammatolerans to cadmium BioProject

    ID: PRJNA110723

    Keywords: Transcriptome or Gene expression

    Access Type: download

    dataset.description: ed. We showed that T. gammatolerans exhibits high resistance to cadmium (Cd), cobalt (Co) and zinc (Zn), a weaker tolerance to nickel (Ni), copper (Cu) and arsenate (AsO4) and that cells exposed to 1mM Cd exhibit a cellular Cd concentration of 67µM. A time-dependent transcriptomic analysis using microarrays was performed at a non-toxic (100μM) and a toxic (1mM) Cd dose. The reliability of microarray data was strengthened by real time RT-PCR validations. Altogether, ...
  4. Gsr1 in Arabidopsis thaliana: A locus inferred to regulate gene expression in response to exogenous glutamine BioProject

    ID: PRJNA159173

    Keywords: Transcriptome or Gene expression

    Access Type: download

    dataset.description: segregation and map location so one mutant, gsr1-1, was selected for intensive analysis. Co-segregation of gsr1 with DNA markers showed the gene was on chromosome 5 between markers CA72 and nga151, an interval of about 0.42 Mbp. The co-segregating mutant phenotypes associated with gsr1 included; yellow color caused by a reduction in chloroplast number; reduced chlorophyll content; decreased nitrate reductase (EC 1.7.1.3) activity in the root; and increased glutamate dehydrogenase (EC 1.4.1.2) activity in root and shoot. Decreased transcripts included those encoding several nitrogen metabolism enzymes. In contrast, the mutation increased only 4 and 7 transcript abundances by more than two fold. RT-PCR showed that in the dark, regula...
