Dynamic mRNA gene expression during a nutritional upshift from proline to glutamine

ABSTRACT: Dynamic mRNA gene expression from the wildtype YSBN6 during a nutritional upshift from proline to glutamine. Glutamine was added to yeast cells growing exponentially on proline as the sole nitrogen source. A sample was taken at steady-state 10 minutes before the shift, and then 3, 7, 10, 14, 24, 56 and 120 minutes after the glutamine addition. Biological triplicate gene expression was measured for samples -10, 7 and 24 minutes after shift, for a total of 14 chips. Changes were generally evaluated relative to the steady-state point (-10 minutes). Biological variability can be assessed from the replicates time points. Other dynamic omics data are associated with this dataset. Consult the publication for more details.

Dynamic mRNA gene expression during a nutritional downshift from glutamine to proline

Project description:Dynamic mRNA gene expression from the wildtype YSBN6 during a nutritional downshift from glutamine to proline. Glutamine and proline were initially together in the media, with cells consuming exlusively glutamine (proline utilization inhibited due to nitrogen catabolite repression). The concentration of glutamine was frequently evaluated at-line, and the moment at which glutamine was not detected anymore is referred to as the time of the shift. Given the uncertainty of the exact time of the shift, two samples were taken at steady-state, approximately 10 and 5 minutes before the shift. Once the shift was identified, samples were taken 3, 7, 10, 14, 24, 56 and 120 minutes after the glutamine depletion. Biological triplicate gene expression was measured for samples -10, 7 and 24 minutes after shift, for a total of 15 chips. Changes were generally evaluated relative to the steady-state point (-10 minutes). Biological variability can be assessed from the replicates time points. Other dynamic omics data are associated with this dataset. Consult the publication for more details.

Dynamic mRNA gene expression following a rapamycin treatment

Project description:Dynamic mRNA gene expression from the wildtype YSBN6 during a rapamycin treatment (rapamycin-induced downshift). Rapamycin was added to yeast cells growing exponentially on glutamine as sole nitrogen source. A sample was taken at steady-state 10 minutes before , and then 3, 7, 10, 14, 24, 56 and 120 minutes after rapamycin treatment. Biological triplicate gene expression was measured for samples -10, 7 and 24 minutes after shift, for a total of 14 chips. Changes were generally evaluated relative to the steady-state point (-10 minutes). Biological variability can be assessed from the replicates time points.

Effect of L-Proline on mouse embryonic stem cells (ESCs)

Project description:We found that the non-essential amino acid L-Proline (L-Pro) acts as a signaling molecule that promotes the conversion of embryonic stem cells (ESCs) into mesenchymal-like, spindle-shaped, highly motile, invasive pluripotent stem cells. This embryonic stem cell-to-mesenchymal-like transition (esMT) is accompanied by a genome-wide remodeling of the transcriptome We used microarrays to elucidate whether a diverse transcriptional program is the basis of the morphological and motility differences between ESCs and L- Proline treated ESCs (PiCs) Total RNA was extracted from Control (ESCs) and L-Proline treated mouse embryonic stem cells (PiCs) and hybridized on Affimetrix microarrays.

Comparison of Aspergillus fumigatus transcriptome grown on selected nitrogen sources

Project description:Transcriptome of A. fumigatus shifted from ammoniumtartrate to different nitrogen sources and incubated for a defined time was compared. After 16h preculture, the fungus was transferred into fresh medium containing ammonium tartrate, sodium nitrate, proline or bsa as nitrogen source. After 1h, fungus was reisolated, RNA was prepared from fungus, transcriptome was assessed and used for further analysis. Ammoniumtartrate, sodiumnitrate, BSA and proline as nitrogen sources, 2 biological replicates for each source. A. fumigatus liquid media shifts were performed according to ref. (Narendja et al.,2002) with minor modifications: 200 ml minimal medium base with 5 mM ammonium tartrate was inoculated with 10^8 conidia freshly harvested. A. fumigatus ATCC 46645 conidia were grown at 37°C and 150 rpm for 16 hours. This pre-culture was then harvested, washed liberally with sterile saline and divided into mycelial masses of equal size on a sterile surface. The portions were then added to 100 ml of minimal medium base without nitrogen source. When a defined carbon source was needed, 1% glucose was added. Flasks were incubated for 20 min at 37°C. Thereafter, one of the following sterile nitrogen sources was added: ammonium tartrate to a final concentration of 5 mM, Sodiumnitrate to a final concentration of 10 mM, 1 g proline suspended in 2 ml minimal medium base, or 0.5 g BSA (Albumin Fraktion V, Roth), suspended in 15 ml minimal medium base. The cultures were incubated for another 60 minutes, harvested by filtering through Miracloth, snap frozen in liquid nitrogen, and ground using a cooled mortar to obtain a fine powder.

mRNA degradation in Mycobacterium smegmatis under aerobic conditions

Project description:Transcription was arrested using 50 ug/ul of rifampin leaving RNA degradation as the sole vector responsible for mRNA abundance. mRNA half-lives were calculated from the decay of signal intensity from T0. Three replicates were sampled before transcription arrest, and after 5 and 10 minutes of mRNA decay for a total of 9 arrays. Five minutes of RNA degradation occurred during the processing of these samples, therefore sample times, indicated in the sample name, represent 0, five, and ten minutes of RNA degradation.

Dynamics of Short-term transcriptomic response of S. cerevisiae to doxorubicin

Project description:Dynamics of short-term effects of doxorubicin, a chemotherapy agent, on S. cerevisiae cells were investigated. After five residence times at steady-state, Yeast cells in chemostat was introduced a doxorubicin pulse to get 20 µM initial doxorubicin concentration. Samples were collected at steady state and at 1, 5, 10, 15, 20, 25, 30, 60, 90, 120 and 180 minutes after the pulse.

Expression data from Pseudomonas putida KT2440: Fuelling the central metabolism with aromatic compounds

Project description:We used Progenika oligonucleotide arrays to monitore the gene expression of P. putida during carbon source stimulus experiments. After ensuring steady state conditions on benzoate, the stimuli were introduced by changing the carbon source from benzoate to glucose, from glucose to fructose and from fructose to benzoate, respectively. The single stimuli were monitored over a time period from 10 to 120 minutes after changing the carbon source by three representative timepoints. Moreover, the steady state conditions were compared among each other. Supplementary file: Individual normalized signal intensity VALUES for each channel of each array are provided in the FullNormalizedMatrix.txt file.
