Skeletal muscle biopsies were taken from the middle gluteal muscle before, immediately after and four hours after exercise.Â Three-condition experiment, Pre exercise (T0), Immediately post exercise (T1), 4 hours post exercise (T2). Hybridisations: T0 vs T1, T0 vs T2 Biological replicates: 8 Technical replication Dye swap

<h4>Background</h4>Selection for exercise-adapted phenotypes in the Thoroughbred racehorse has provided a valuable model system to understand molecular responses to exercise in skeletal muscle. Exercise stimulates immediate early molecular responses as well as delayed responses during recovery, resulting in a return to homeostasis and enabling long term adaptation. Global mRNA expression during the immediate-response period has not previously been reported in skeletal muscle following exercise i ...[more]

Automated array-CGH optimized for archival formalin-fixed, paraffin-embedded tumor material

Project description:BACKGROUND: Array Comparative Genomic Hybridization (aCGH) is a rapidly evolving technology that still lacks complete standardization. Yet, it is of great importance to obtain robust and reproducible data to enable meaningful multiple hybridization comparisons. Special difficulties arise when aCGH is performed on archival formalin-fixed, paraffin-embedded (FFPE) tissue due to its variable DNA quality. Recently, we have developed an effective DNA quality test that predicts suitability of archival samples for BAC aCGH. METHODS: In this report, we first used DNA from a cancer cell-line (SKBR3) to optimize the aCGH protocol for automated hybridization, and subsequently optimized and validated the procedure for FFPE breast cancer samples. We aimed for highest throughput, accuracy, and reproducibility applicable to FFPE samples, which can also be important in future diagnostic use. RESULTS: Our protocol of automated array-CGH on archival FFPE ULS-labeled DNA showed very similar results compared with published data and our previous manual hybridization method. CONCLUSION: This report combines automated aCGH on unamplified archival FFPE DNA using non-enzymatic ULS labeling, and describes an optimized protocol for this combination resulting in improved quality and reproducibility. In this study, we optimized the BAC araay-CGH protocol for automated hybridization for FFPE breast cancer samples. We have tested hybridization temperature and duration, different hybridization buffer conditions, and post-hybridization washing.

Facing warm temperatures during migration M-bM-^@M-^S cardiac mRNA responses of two adult sockeye salmon Oncorhynchus nerka populations to warming and swimming challenges

Project description:The main findings of the current study were that exposing adult sockeye salmon Oncorhynchus nerka to a warm temperature that they regularly encounter during their river migration induced an mRNA-level heat shock response that is exacerbated with swimming. Similar immune defense-related responses were also observed. Microarray analyses revealed that 347 genes were differentially expressed between the cold (12-13M-BM-0 C) and warm (18-19M-BM-0 C) treated fish (P < 0.01), with stress response (GO:0006950; P = 0.014) and response to fungus (GO:0009620; P = 0.003) elevated with warm treatment, while expression for genes involved in oxidative phosphorylation (GO:0006119; P = 0.0019) and electron transport chain (GO:0022900; P = 0.00043) increased in cold-treated fish. By studying single genes with RT-qPCR, warm treatment fish from the Chilko population of O. nerka induced expression of heat shock protein (hsp) 90M-NM-1, hsp90M-NM-2 and hsp30, as well as interferon-inducible protein (P < 0.05). A Nechako population of O. nerka with a narrower thermal tolerance window than the Chilko population showed even more pronounced responses to the warm treatment. In conclusion, it appears that during their once-in-the-lifetime migration these adult sockeye salmon encounter conditions that induce several cellular defense mechanisms. As river temperatures continue to increase, it remains to be seen whether or not these cellular defenses provide enough protection for all sockeye salmon populations. Two condition experiment; cold treated fish vs. warm treated fish, n=4 in both group

Transcription profiling by array for comparison of industrial Escherichia coli strains on growth, transcriptome and proteome level in batch cultivations to identify strain specific features (subexperiment K-12 platform)

Project description:The objective of the current study was to evaluate the performance of frequently used E. coli K-12 strains HMS174 and RV308 in the context of industrial cultivations. To meet this objective, we carried out batch cultivations with high-glucose media in computer-controlled bioreactors and applied transcriptome analysis to interpret phenotypic attributes at the molecular level. The resulting enhancement of knowledge about host physiology is expected to contribute to the acceleration of improvements and optimizations in related biotech processes.

Transcription profiling of E. coli HMS174(DE3)(pET30aNproGFPmut3.1) to analyze cellular response to limited induction with IPTG

Project description:This transcription profiling time course experiment was conducted in order to analyze the cellular response of the T7 RNA polymerase based E. coli expression system HMS174(DE3)(pET30aNproGFP) to a limited induction with isopropyl-beta-D-galactoside (IPTG). The used cell material was produced under well controlled and defined conditions in an exponential carbon limited fed-batch cultivation at a growth rate of 0.1 per hour. One doubling past feed start induction was started by continuously feeding limiting amounts of inducer gaining in a constant IPTG to cell dry weight ratio of 1µmol/g. Due to the low induction level a physiologically tolerable recombinant gene expression rate was generated and production period was significantly elongated. Non induced cells sampled at the time point of induction were used as reference and compared to cells subsequently sampled during the production period (sampling frequency 2 hours).

Transcription profiling of E. coli BL21(DE3) to analyze the cellular response to high level expression of recombinant human super-oxide-dismutase (SOD)

Project description:This transcription profiling time course experiment was conducted in order to analyze the cellular response of E. coli BL21(DE3) to high level expression of recombinant human super-oxide-dismutase (SOD) on the transcriptional level. Three biological replicates were generated by using a carbon limited exponential fed-batch cultivation similar to industrial setups for large scale production. For induction of the system a single pulse of isopropyl-beta-D-galactoside (IPTG) yielding in a fully induced system is applied one doubling past feed start. In order to achieve a proper timeresolution of cellular responses sampling starts with a high frequency for the first hours past induction and decreases in the course of the experiment.
