Consequences of reductive evolution for gene expression in an obligate endosymbiont.

Wilcox Jennifer L JL Dunbar Helen E HE Wolfinger Russell D RD Moran Nancy A NA

Molecular microbiology 20030601 6

The smallest cellular genomes are found in obligate symbiotic and pathogenic bacteria living within eukaryotic hosts. In comparison with large genomes of free-living relatives, these reduced genomes are rearranged and have lost most regulatory elements. To test whether reduced bacterial genomes incur reduced regulatory capacities, we used full-genome microarrays to evaluate transcriptional response to environmental stress in Buchnera aphidicola, the obligate endosymbiont of aphids. The 580 genes ...[more]

Hepatic proteome analysis of Atlantic salmon (Salmo salar) after exposure to environmental concentrations of human pharmaceuticals

Project description:Pharmaceuticals are pseudo persistent aquatic pollutants with unknown effects at environmentally relevant concentrations. Atlantic salmon (Salmo salar) were exposed to Acetaminophen: 54.77 ± 34.67; Atenolol: 11.08 ± 7.98 and Carbamazepine: 7.85 ± 0.13 µg•L-1 for 5 days. After Acetaminophen treatment, 19 proteins were differently expressed, of which 11 were significant with respect to the control group (eight up-regulated and three down-regulated). After Atenolol treatment, 7 differently expressed proteins were obtained in comparison with the control, of which 6 could be identified (four up-regulated and 2 down-regulated). Carbamazepine exposure resulted in 15 differently expressed proteins compared with the control, with 10 of them identified (seven up-regulated and three down-regulated). Out of these, 3 features were common between Acetaminophen and Carbamazepine and one between Carbamazepine and Atenolol. One feature was common across all treatments. Principal component analysis and heat map clustering showed a clear grouping of the variability due to the applied treatments. The obtained data suggest (1) that exposure to environmentally relevant concentrations of the pharmaceuticals alters the hepatic protein expression profile of the Atlantic salmon; and (2) the existence of treatment specific processes that may be useful for biomarker development.

Steroids_Effect_on_HUVEC_Response_to_LPS_or_Cytokines

Project description:Pooled first passage cryopreserved, human umbilical vein endothelial cells (HUVEC) were obtained from Cascade Biologics (Portland, OR), thawed, and cultured according to the supplierâs recommendations in Medium 200. After thawing, cells were seeded onto 0.2% gelatin coated tissue culture plates and cultivated under 95% air, 5% CO2 at 37 oC. Confluent cells were cultured in steroids-depleted medium for 96 hrs before the addition of 17Î²-estradiol (17Î²E) or hydrocortisone (H) to 1 ÂµM for 5 hrs. For Lipopolysaccharide (LPS) or cytokine mix (CM)-treatments, cells or pretreated with vehicle (0.1% ethanol), 1ÂµM 17Î²E, or H for 1 hr were exposed to 100 ng/ml LPS or a mixture of proinflammatory cytokines (CM, 500 U/ml IL-1b, 2500 U/ml TNF-Î±, and 1250 U/ml IFN-Î³) for 4 hours. All treatments were done in quadruplicates. At the end of treatment, total cellular RNA was isolated.
