Deciphering a functional gene network underlying robustness to protein overproduction

ABSTRACT: We systematically investigated the impact of genetic variation and the environment on protein overproduction costs in Saccharomyces cerevisiae To identify genes mediating protein overproduction costs, genetic perturbations were applied. The yEVenus overexpression plasmid was crossed into gene deletion backgound. The generation of double mutant strains enabled us to investigate the transcriptional response of the cells under two different internal stress: deletion of a given gene, plus the overexpression of a gratuitous protein To explore the cellular response under gratuitous protein overproduction, a sensitized background was used (sse1 deletion). Our aim was to identify differentially expressed genes upon protein overproduction. 3-3 biological replicates were used for the control (single deletion strain with an empty plasmid) and for the overexpression strains (single deletion strain with yEVenus multi-copy plasmid) as well. The cellular response to overexpression was normalized to the control sse1 deletion strain, without overexpression.

Membrane protein overproduction stress in Bacillus subtilis

Project description:Comparison of the transcriptome of Bacillus subtilis under going membrane protein overproduction in the wild type, sigW and cssRS deletion strains. We demonstrate that the dynamics of the stress systems involved in membrane overproduction are far more complicated than was first hypothesised and that many more systems than SigW and CssRS are involved in membrane protein overexpression stress. Interestingly the cssRS genes are repressed in the sigW deletion strain.

Comparing the transcriptional profiles of a Caulobacter crescentus phyR null mutant to a xylose-inducible phyR overexpression strain

Project description:phyR encodes a general stress regulator protein that is conserved among several alpha-proteobacteria. This experiment is quantifying transcription in two Caulobacter strains: one strain is overexpressing phyR (gene CC3477); the other carries a phyR in-frame deletion. Both strains were cultured in M2 defined medium with xylose as the sole carbon source. The first strain (FC626) carries a plasmid integrated into the xylX locus; phyR is fused to the xylX promoter in this plasmid, generating a xylose-inducible phyR overexpression strain. The second strain (FC799) carries an in-frame deletion at the chromosomal phyR locus.

Ssn6 Overexpression

Project description:We have performed a genome wide expression profile study of the essential transcriptional co-repressor protein Ssn6 in Schizosaccharomyces pombe. Ssn6 affected targets were identified by over expression of Ssn6 protein in a WT strain. A WT strain holding a plasmid expressing Ssn6 (pDUAL-Ssn6) was compared against the expression in a WT with the empty plasmid (pDUAL-EMPTY) strain. Keywords: Overexpression/WT

A trade-off for maintenance of multidrug-resistance IncHI2 plasmids in Salmonella Typhimurium through co-evolution

Project description:Plasmid maintenance costs to bacterial hosts is closely linked to the mechanisms that underlie plasmid fitness and how these costs are resolved. Herein, we performed multiple (63) serial passage to explore the compensatory mechanisms of co-evolution of multidrug-resistant IncHI2 plasmid pJXP9 and S. Typhimurium strain ATCC 14028 with or without antibiotic selection. pJXP9 could be maintained at for hundreds of generations even without drug exposure. Decreased lag times and higher competitive advantages were observed in end-point evolved strains bearing pJXP9 compared to ancestral strains. Genomic and transcriptomic analyses revealed that the fitness costs of pJXP9 in ATCC 14028 were derived from not only specific plasmid genes, particularly the multidrug-resistant region and conjugation transfer region I, but also the conflicts resulting from chromosomal gene interactions. Correspondingly, plasmid-borne deletions of these regions could compensate the fitness cost due to the presence of the plasmid. Furthermore, mutations and mRNA alterations in chromosomal genes involved in physiological functions were also adaptative. These functions included decreased flagellar motility, oxidative stress resistance and fumaric acid synthesis, and increased Cu resistance. Our findings suggest that plasmid maintenance through plasmid-bacteria co-evolution is a trade-off between increasing plasmid vertical transmission and impairing its horizontal transmission and bacterial physiological phenotypes.

RNA-seq of E. coli strains overproducing DNA \\"damage-up\\" proteins (DDPs)

Project description:This experiment assesses gene expression changes in response to the overproduction of DNA \\"damage-up\\" proteins (DDPs). These proteins, when overproduced, activate the SOS DNA damage response and were identified in a genome-wide overproduction screen using the mobile plasmid collection (Saka et al 2005). For the RNA-seq experiments, 7 DDP overproduction strains were compared to an empty vector control strain.

Transcription profiling by array of abx1 deletion or over expression in Streptococcus agalactiae and comparision with the effect of CovS and CovR deletion

Project description:Analysis of the impact of the abx1 deletion or over expression on S. agalactaie transcription profile and comparision to the effect of CovS and CovR deletion on transcriptomic profile. Some of the mutants are gene_knock_out mutants, but in other strains we have tested the over expression of the Abx1 protein by an chromosomic overexpression, or by a plasmid overexpression. Chromosomic overexpression is indicated with a K and plasmid overexpression with a V.

Agarase overproduction in Streptomyces lividans

Project description:The gene dagA encoding agarase in Streptomyces coelicolor was cloned in the multicopy plasmid pIJ486 generating plasmid pAGAs5. Plasmid pAGAs5 and pIJ486 were propagated in S. lividans TK21 to obtain S. lividans TK21(pAGAs5) and its isogenic strain S. lividans TK21(pIJ486). Transcriptional profiling of the bacterium that overproduces agarase mainly resulted in the downregulation of the genes involved in the biogenesis and function of ribosomes, together with the downregulation of the genes involved in nitrogen, aminoacids, purine/pyrimidine and central carbon metabolism as well as ABC transporters, redox processes and fatty acids biosynthesis. The number of genes upregulated in the agarase overproducer strain is lower than in the downregulated ones. Almost 50% of the dowregulated genes have been described as forming part of the stringent response in streptomycetes. Therefore, the overproduction of agarase may lead to a condition of nutrient depletion that triggers the stringent response.
