Contrasting patterns of expression divergence in early and late stages of population divergence in mice

ABSTRACT: We compared gene expression differences in the polytypic species complex Mus musculus (Mus musculus musculus, Mus musculus domesticus, Mus musculus castaneus and Mus musculus ssp) with that of Mus spretus via oligonucleotide microarrays representing more than 20,000 genes. Analysis of the results by two way ANOVA statistics suggests that the most genes with significant differences in expression levels among the subspecies are found in liver and kidney and the least in testis. This picture is different when one compares with Mus spretus, where the largest number of differences is found in testis. The design we employed is a reference design. All tissues were hybridized against a pool of that same tissue from 9 C57BL6 mice. All mice were roughly 12 weeks of age. To control for biological variation, we have used several individual males from each sub-species. RNA was isolated from three different organs, namely brain, liver/kidney and testis.

Regulatory changes in genes involved in reproduction are thought to be prime targets for divergence during speciation, since they are expected to play an important role in sexual selection and sexual conflict. We used microarray analysis of RNA from different wild populations of house mouse subspecies (including Mus m. musculus, Mus m. domesticus, and Mus m. castaneus) and from the sister species Mus spretus to test this assumption. A comparison of expression divergence in brain, liver/kidney, a ...[more]

Project description:Microarray analysis was used to identify the fludioxonil-responsive genes dependent on SskA, SrrA, HogA, and AtfA in the filamentous fungus Aspergillus nidulans. In order to identify such genes, we conducted the several types of experiment. One was a comparison between wild type treated with fludioxonil and without the treatment (Exp.1). Others were comparison between wild type treated with fludioxonil and each mutant (sskA, Exp.2; srrA, Exp.3; hogA, Exp.4; atfA, Exp.5) treated with fludioxonil. Compared the result of Exp.1 with that of other experiments, we could identify the genes whose expression was induced or repressed in response to fludioxonil in a manner dependent on SskA, SrrA, HogA, or AtfA. KEY WORD; Aspergillus nidulans, fludioxonil, SskA, SrrA, HogA, AtfA Conidia of wild type or each mutant were cultured at 37C in 100ml CD medium containing 2% glucose for 18h and treated with fludioxonil (final concentration; 10 ug/ml) or DMSO (as a solvent control) for 15 min. The mycelia were harvested and frozen in liquid nitrogen, ground to powder, and used for RNA preparation. mRNA was purified and used for hybridization experiments. A total of 2 hybridizations were performed for each microarray experiment described in the summary. The following replicates were carried out: 1. In-slide replicates were carried out for each analysis. 2. Dye swap replicates were carried out for each experiment. The slides were scanned with an Axon GenePix 4000B scanner (Molecular Devices). The resulting TIFF images were imported into GenePix Pro and fluorescent intensity of spots were calculated for each of the Cy3 and Cy5 channels. Global normalization was applied to all analyses. Following normalization, spots whose Cy3 or Cy5 intensity was less than 0 were removed from the data set (the exceptional case was that intensity of the other channel was more than 100). The dye-swap replicates and in-slide replicates were subjected to all analyses. Finally, gene expression ratios (test/reference) were calculated for each replicates. Gene expression was considered to be significantly higher or lower whenever the spot intensity changed by at least 3-fold in all four replicates for each experiment.

Project description:Microarray analysis was used to identify the calcium-responsive genes dependent on CrzA in the filamentous fungus Aspergillus nidulans. In order to identify such genes, we conducted the two types of experiment. One was a comparison between wild type with calcium treatment and wild type without calcium treatment. Another was a comparison between wild type with calcium treatment and crzA mutant with calcium treatment. From a comparison between the results of these experiments, we could identify the genes whose expression was induced or repressed in response to calcium in a manner dependent on CrzA. KEY WORD; Aspergillus nidulans, calcium response, crzA Conidia of wild type or crzA mutant strains were incubated at 37C in CD medium for 18h and treated with or without calcium (final concentration; 50 mM) for 15 min. The mycelia were harvested and frozen in liquid nitrogen, ground to a powder, and used for RNA preparation. mRNA was purified and used for hybridization experiments. A total of 2 hybridizations were performed for each microarray experiment described in the summary. The following replicates were carried out: 1. In-slide replicates were carried out for each analyses. 2. Dye swap replicates were carried out for each analyses. The slides were scanned with an Axon GenePix 4000B scanner (Molecular Devices).

Following normalization, spots whose Cy3 or Cy5 intensity was less than 0 were removed from the data set (the exceptional case was that intensity of the other channel was more than 100). The dye-swap replicates and in-slide replicates were subjected to all analyses. Finally, gene expression ratios (channel 2/channel 1) were calculated for each replicates. Gene expression was considered to be significantly higher or lower whenever the spot intensity changed by at least 2-fold in all four replicates.

Project description:Microarray analysis was used to identify the osmotic stress-responsive genes dependent on HogA and AtfA in the filamentous fungus Aspergillus nidulans. In order to identify such genes, we conducted the several types of experiment. One was a comparison between wild type with and without osmotic shock (Exp.6). Others were comparison between wild type with osmotic shock and each mutant (hogA, Exp.7; atfA, Exp.8) with osmotic shock. Compared the result of Exp.6 with other experiments, we could identify the genes whose expression was induced or repressed in response to osmotic stress in a manner dependent on HogA and AtfA. KEY WORD; Aspergillus nidulans, osmotic stress, HogA, AtfA Conidia of wild type or each mutant were cultured at 37C in 100ml CD medium containing 2% glucose for 18h, and 50 ml of 3 M sorbitol was added (final concentration; 1 M) or equivalent volume of water (as a control) for 15 min. The mycelia were harvested and frozen in liquid nitrogen, ground to powder, and used for RNA preparation. mRNA was purified and used for hybridization experiments. A total of 2 hybridizations were performed for each microarray experiment described in the summary. The following replicates were carried out: 1.

Gene expression was considered to be significantly higher or lower whenever the spot intensity changed by at least 2-fold in all four replicates for each experiment.

Project description:The induction of genetic competence is a strategy used by bacteria to increase their genetic repertoire under stressful environmental conditions. Recently, Streptococcus pneumoniae has been shown to co-ordinate the uptake of transforming DNA with fratricide via increased expression of the peptide pheromone responsible for competence induction. Here, we document that environmental stress-induced expression of the peptide pheromone competence-stimulating peptide (CSP) in the oral pathogen Streptococcus mutans. We showed that CSP is involved in the stress response and determined the CSP-induced regulon in S. mutans by microarray analysis. Contrary to pneumococcus, S. mutans responds to increased concentrations of CSP by cell lysis in only a fraction of the population. We have focused on the mechanism of cell lysis and have identified a novel bacteriocin as the M-bM-^@M-^Xdeath effectorM-bM-^@M-^Y. Most importantly, we showed that this bacteriocin causes cell death via a novel mechanism of action: intracellular action against self. We have also identified the cognate bacteriocin immunity protein, which resides in a separate unlinked genetic locus to allow its differential regulation. The role of the lytic response in S. mutans competence is also discussed. Together, these findings reveal a novel autolytic pathway in S. mutans which may be involved in the dissemination of fitness-enhancing genes in the oral biofilm. Streptococcus mutans UA159 were grown with 2 uM CSP or without (uninduced control) to mid-log phase. Total RNA was extracted as described above. The cDNAs were prepared for hybridization using the PFGRC protocol. Microarray chips were scanned using a Gene Pix 4000B (Axon) and analyzed using the TM4 Microarray Software Suite (http://www.tm4.org/). Transcript levels were measured by cDNA hybridized to a fourfold redundant S. mutans microarray and averaged for three replicated hybridizations. Differential gene expression was based on a post-normalization cut-off of M-BM-1> twofold.
