Genome-Wide Transcriptional Responses of Nitrosomonas europaea to Zinc

(Submitter supplied) Nitrosomonas europaea is a Gram-negative obligate chemolithoautotroph that derives energy for growth through oxidation of ammonia and participates in the process of nitrification in global nitrogen cycling. The physiological, proteomic, and transcriptional responses of N. europaea to zinc stress were studied. The nitrite production rate and ammonia-dependent oxygen uptake rate of the cells exposed to 3.4 uM ZnCl2 decreased about 61 % and 69 % within 30 minutes, respectively. more...

Steady state growth under inorganic carbon limitation increases energy consumption for maintenance and enhances nitrous oxide production in Nitrosomonas europaea

(Submitter supplied) Nitrosomonas europaea is a chemolithoautotrophic bacterium that oxidizes ammonia (NH3) to obtain energy for growth on carbon dioxide (CO2), and can also produce nitrous oxide (N2O), a greenhouse gas. We interrogated the growth, physiological, and transcriptome responses of N. europaea to replete (> 5.2 mM) and limited inorganic carbon (IC) provided by either 1.0 mM or 0.2 mM sodium carbonate (Na2CO3) supplemented with atmospheric CO2. more...

Nitrosomonas europaea cells treated with chloroform for one hour and compared to untreated cells

(Submitter supplied) We analyzed the global transcriptional response of N. europaea when exposed to chloroform (7 µM for 1 h). Chloroform led to down regulation of 501 genes and up regulation of 251 genes. These up regulated genes included genes for heat shock proteins, sigmafactors of extracytoplasmic function subfamily and newly identified genes of toxin-antitoxin loci in N. europaea. Our study showed that despite a significant decrease of transcription in response to the stress, N. more...

Expression data from brain tissue of Rattus norvegicus treated with D-Serine

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...
