Time series (T= 0-4 hours) for E. coli K-12 MC4100 after a shift from 23˚C to 37˚C (M9 minimal glycerol medium, exponential phase growth)

ABSTRACT: We investigated the effect of a temperature shift from 23˚C to 37˚C, mimicking the temperature transition experienced by a microbe as it enters a human host. This strategy allowed the exploration of the kinetics of gene expression changes in immediate response to a temperature upshift and to characterize the suite of genes required to respond to 37˚C in the first few hours. We demonstrate that a significant number of genes are rapidly altered in expression within minutes to hours after a temperature shift. Some are only induced transiently, while are required for long-term adaptation. Many of these genes are related to metabolism, stress response, and immune evasion suggesting that temperature may serve as a sentinel cue to predict and prepare for niche adaptation in the host.

Gene expression in E.coli K-12 MC4100 at 37˚C and 23˚C in M9 glycerol exponential phase growth

Project description:Because many virulence genes in E. coli and other pathogens are regulated by temperature, we wanted to determine on a genome-wide scale which genes are modulated in adapting to both human host temperature (37˚C) and ambient room temperature (23˚C). Overall, 126 genes were found to be more highly expressed at 37˚C (1) whereas 297 genes were more highly expressed at 23˚C (2). Genes involved in the uptake and utilization of amino acids, carbohydrates, and iron dominated the 37˚C list, supporting a model in which temperature serves as a host cue to increase expression of bacterial genes needed for growth. 122 of the 297 genes more highly expressed at 23˚C are RpoS-controlled, confirming genome-wide the model that low temperature serves as a primary cue to trigger the general stress response. Several genes expressed at 23˚C overlap with the cold shock response, suggesting that strategies used to adapt to sudden shifts in temperature also mediate long-term growth at 23˚C. Another category of genes more highly expressed at 23˚C are associated with biofilm development, implicating temperature as an important cue influencing this developmental pathway. 1.)

Transcription profiling by array of Candida albicans populations exposed to a temperature shift from 25 degrees to 37 degrees

Project description:Seperate White and Opaque Candida albicans populations were exposed to a temperature shift from 25 degrees to 37 degrees. Samples were then harvested at various time points to follow the effects of the shift on the two cell types, particularly the opaque cell type which switches to the white cell type after several hours at 37 degrees.

Temperature dependent gene expression levels at 28°C and 37°C for Pseudomonas aeruginosa PAO1

Project description:To further understand the gene expression characteristics of Pseudomonas aeruginosa PAO1, we have applied whole genome microarray expression profiling as a discovery platform to specify the temperature dependent expression of PAO1 genome at soil and human body temperature. We selected 28°C as temperature representative of the soil niche and 37°C for human body. The results from the temperature dependent transcriptome analysis are consistent to our previous published data that the phzM, ptsP and lasI genes expression is upregulated at 37°C [11]. The comparison analysis of the M18 genome expressional profiles at 28°C and 37°C indicated a total of 596 genes expressed in a temperature dependent manner over two fold.
