Gene expression profiling and phenotype analyses of S. cerevisiae in response to changing copper reveals six genes with new roles in copper and iron metabolism.

Physiological genomics 20050510 3

Exhaustive microarray time course analyses of Saccharomyces cerevisiae during copper starvation and copper excess reveal new aspects of metal-induced gene regulation. Aside from identifying targets of established copper- and iron-responsive transcription factors, we find that genes encoding mitochondrial proteins are downregulated and that copper-independent iron transport genes are preferentially upregulated, both during prolonged copper deprivation. The experiments also suggest the presence of ...[more]

Tiling path analysis of seven temperature sensitive S. cerevisiae BY4741 mutants

Project description:Seven temperature sensitive Saccharomyces cerevisiae BY4741 mutants (rsc3-1, abf1-101, reb1-212, rap1-1, mcm1, tbf1 and cep3-1) were grown at restrictive temperatures until a difference in OD600 was observed relative to a wild-type control. Nucleosomal DNA, whole genomic DNA and total RNA were isolated and hybridized onto yeast whole-genome tiling arrays.

Transcription profiling of mouse embryonic stem cells with a doxycycline-inducible Xist cDNA transgene introduced into chromosome 17

Project description:A doxycycline-inducible Xist cDNA transgene was introduced into mouse chromosome 17 at approximately 71.24Mb (NCBI Build m36). Insertion of the transgene was heterozygous, so only one copy of chromosome 17 carried the transgene, and the other chromosome 17 was wild-type. Upon doxycycline induction, the transgene is expressed, producing Xist transgene RNA which localises to autosomal material in cis, leading to silencing of genes adjacent to the transgene. Due to the heterozygous nature of transgene insertion and the cis nature of silencing, for any silenced gene, the maximum possible downregulation in expression levels was 50%. To quantify the changes in the levels of gene expression in response to Xist transgene expression, total RNA was extracted from undifferentiated and differentiated ES cells treated with doxycycline. As background control, total RNA was also prepared from uninduced cells (both undifferentiated and differentiated, cultured in parallel to doxycycline-treated cells). The total RNA was then used to make labelled cRNA, which was hybridised to an Affymetrix GeneChip Mouse Genome 430 2.0 array.

Transcription profiling of mouse embryonic stem cells with a doxycycline-inducible Xist cDNA transgene introduced into chromosome 3

Project description:A doxycycline-inducible Xist cDNA transgene was introduced into mouse chromosome 3 at approximately 99.79Mb (NCBI Build m36). Insertion of the transgene was homozygous, so only one copy of chromosome 3 carried the transgene, and the other chromosome 3 was wild-type. Upon doxycycline induction, the transgene is expressed, producing Xist transgene RNA which localises to autosomal material in cis, leading to silencing of genes adjacent to the transgene. Due to the homozygous nature of transgene insertion and the cis nature of silencing, for any silenced gene, the maximum possible downregulation in expression levels was 50%. To quantify the changes in the levels of gene expression in response to Xist transgene expression, total RNA was extracted from undifferentiated and differentiated ES cells treated with doxycycline for three days. As background control, total RNA was also extracted from uninduced cells (both undifferentiated and differentiated, cultured in parallel to doxycycline-treated cells). cRNA was labelled from the total RNAs, and then hybridised to Affymetrix GeneChip Mouse Genome 430 2.0 arrays.

Gene transcription from the linear plasmid pBClin15 leads to cell lysis and extracellular DNA dependent aggregation of B. cereus ATCC 14579 in response to quinolone induced stress

Project description:Several members of the Bacillus cereus group of bacteria carry lysogenic phages of the family Tectiviridae. The Bacilus cereus reference strain (ATCC 14579) harbor a linear plasmid (pBClin15) that is highly similar to the genomes of the Tectiviruses. Production of active phages has however never been reported for pBClin15 and the role of pBClin15 in B. cereus physiology has been enigmatic. We have for the first time demonstrated an effect of pBClin15 on the physiology of B. cereus ATCC 14579 whereby the wild type is more sensitive to DNA damaging antibiotics compared to a pBClin15 cured strain. The microarray experiments in this study were designed to highlight transcriptional differences between the B. cereus ATCC 14579 wild type and a plasmid cured variant that potentially could explain the impact of pBClin15 on the B. cereus physiology. Microarray experiments were carried out under non-stressful conditions (growth in logarithmic phase in LB medium) under which there were no phenotypic difference between the wild type and pBClin15 cured strain as well as under stressful conditions under which there were phenotypic differences between the two strain (growth in LB medium supplemented with 0.5M-5g norfloxacin per ml).

Transcription profiling by array of Burkholderia cenocepacia J2315 was exposed to heat stress and to stress form reactive oxygen species

Project description:B. cenocepacia J2315 was exposed to heat stress and to stress form reactive oxygen species. To expose the cultures to heat stress, cells were grown at 37ºC to an O.D. of 0.4 to 0.45 and then transferred into a different shaking incubator at 42.5ºC, incubated for 1 hour at 150 rpm and harvested. To expose cultures to oxidative stress by reactive oxygen species, cells were grown at 37ºC to an OD of 0.5. Then t butyl hydroperoxide or hydrogen peroxide solution were added to the culture at 0.001% and 0.15% final concentration. The culture was further incubated for 15 min and then harvested. The expression profiles were compared to cells grown in LB medium without exposure to stress.
