Transcription profiling of Streptomyces ceolicolor M600 and J2139 (sigR deletion) strains

ABSTRACT: In Streptomyces coelicolor the SigR sigma factor controls genes involved in coping with the deleterious formation of disulphide bonds in cellular proteins. This experiment provides global gene expression patterns of M600 and J2139 (sigR deletion) grown in NMMP plus glucose medium to mid-log phase then treated with diamide. The data reveal that sigR activates, directly or indirectly, more than 65 transcription units, encoding functions that include thiol-disulphide oxidoreductases, thiol buffers, and ATP-dependent proteases. The sigR regulon partially overlaps the ClgR and HspR regulons, that include functions for protein degradation and protein refolding. Diamide also leads to the transient down-regulation of central metabolic gene expression, in particular ribosomal protein expression.

Transcription profiling of Streptomyces coelicolor wild type and zur deletion strains

Project description:Description: In Streptomyces coelicolor the Zur repressor controls genes involved in zinc uptake and alternative ribosomal proteins that lack structural zinc. This experiment provides global gene expression patterns of M145 and S121 (zur deletion) grown in NMMP plus glucose medium to mid-log phase. The data reveal that Zur also controls genes involved in production of a non-ribosomally encoded siderophore-related peptide designated coelibactin.

Transcription profiling of Streptomyces coelicolor wild type and phP-null mutants at different time points during phosphate starvation

Project description:S. coelicolor was grown in low-phosphate concentration R5 liquid medium which facilitated the transition to a phosphate starvation induced stationary phase and the subsequent induction of the PhoP regulon. Global gene expression profiling of a wild-type and a phoP-null mutant was performed using samples isolated, respectively, at 24, 30, 35 and 45 h of growth. RNA was extracted and the resulting cDNA was hybridised to S. coelicolor high density DNA microarrays.

Transcription profiling of community-acquired invasive and nasal carriage S.aureus isolates to identify genes associated with invasion, genomic variability and population structure

Project description:Staphylococcus aureus is the most common cause of hospital-acquired infection. In healthy hosts outside of the health care setting, S.aureus is a frequent colonizer of the human nose but rarely causes severe invasive infection such as bacteremia, endocarditis, or osteomyelitis. To identify genes associated with community-acquired invasive isolates, regions of genomic variability, and the S.aureus population structure, we compared 61 community-acquired invasive isolates of S.aureus and 100 nasal carriage isolates from healthy donors using a microarray spotted with PCR products representing every gene from the seven S.aureus sequencing projects. The core genes common to all strains were identified, and 10 dominant lineages of S.aureus were clearly discriminated. Each lineage carried a unique combination of hundreds of core variable (CV) genes scattered throughout the chromosome, suggesting a common ancestor but early evolutionary divergence. Many CV genes are regulators of virulence genes or known or predicted to be expressed on the bacterial surface and to interact with the host during nasal colonization and infection. Within each lineage, isolates showed substantial variation in the carriage of mobile genetic elements and their associated virulence and resistance genes, indicating frequent horizontal transfer. However, we were unable to identify any association between lineage or gene and invasive isolates. We suggest that the S.aureus gene combinations necessary for invasive disease may also be necessary for nasal colonization and that community-acquired invasive disease is strongly dependent on host factors.

Transcription profiling of mouse liver and kidney from PAR bZip triple knockout mice to wild-type or heterozygous mutant mice to identify genes contributing to the morbidity of PAR bZIP triple KO mice and circadian liver detoxification

Project description:The PAR-domain basic leucine zipper (PAR bZip) transcription factors DBP, TEF, and HLF accumulate in a highly circadian manner in several peripheral tissues, including liver and kidney. Mice devoid of all three of these proteins are born at expected Mendelian ratios, but are epilepsy-prone, age at an accelerated rate and die prematurely. In the hope of identifying PAR bZip target genes whose altered expression might contribute to the high morbidity and mortality of PAR bZip triple knockout mice, we compared the liver and kidney transcriptomes of these animals to those of wild-type or heterozygous mutant mice. These experiments revealed that PAR bZip proteins control the expression of many enzymes and regulators involved in detoxification and drug metabolism, such as cytochrome P450 enzymes, carboxylesterases, and constitutive androstane receptor (CAR). Indeed, PAR bZip triple knockout mice are hypersensitive to xenobiotic compounds, and the deficiency in detoxification may contribute to their early ageing.
