Project description:Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related. These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. The brown algae are also important because they are one of only a very small number of eukaryotic lineages that have evolved complex multicellularity. This work used whole genome tiling array approach to generate a comprehensive transcriptome map of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for the brown algae. Keywords: high-resolution tiling array, brown algae, ectocarpus
Project description:Here, we integrated high-throughput transcriptome and proteome sequencing to construct a comprehensive protein database for the byssus of Chinese green mussel (Perna viridis), aiming at providing novel insights into the molecular mechanisms of byssal binding to heavy metals.
Project description:Bacillus subtilis vegetative cells switch to sporulation upon nutrient limitation. To investigate the proteome changeover during sporulation, a time-lapse proteomic analysis was performed in a cell population that was induced to sporulate synchronously. Here, we are the first to comprehensively investigate the changeover of sporulation regulatory proteins, coat proteins and other proteins involved in sporulation and spore biogenesis. Protein co-expression analysis revealed four co-expressed modules. Modules brown and green are upregulated during sporulation and are annotated as associated with sporulation. Module blue, which is negatively correlated with modules brown and green, comprised ribosomal and metabolic proteins, and module yellow is co-expressed with module blue and modules brown & green. Notably, several proteins not belonging to any of the known transcription regulons were identified as co-expressed with modules brown and green. We speculate that they may also play roles during sporulation. Finally, amounts of some coat proteins, for example morphogenetic coat proteins, decreased late in sporulation. While we speculate on their possible role in guiding or helping assembly of other coat proteins, after which they can be disposed of, such a hypothesis remains to be experimentally addressed.

Keywords: high-resolution tiling array, brown algae, ectocarpus The slides were hybridised with two, labelled samples: 1) a mixture of labelled cDNA corresponding to RNA samples from mature sporophytes and gametophytes and from immature sporophytes stressed either in high salt medium or by addition of hydrogen peroxide and 2) genomic DNA as a control.

Project description:Next generation sequencing was used to compare transcriptome profiling in brown adipose tissue from Ctrl and BKO mice with mature brown adipose tissue specific deletion of BSCL2. Using an optimized data analysis workflow, we identified 13,525 transcripts in brown adipose tissue. 243 genes were differentially expressed with a fold change ≥1.5 and Padj value <0.05. Only 99 genes showed differential expression between the Ctrl and BKO brown fat, with a fold change ≥2.0 and Padj value <0.05. Results provide insights into the processes and signaling pathways BSCL2-mediated in brown adipose tissue.
Project description:Expression levels of human genes vary extensive among individuals. Gene expression determines cell function and characteristics thus this variation likely contributes to phenotypic variation. Genetic studies have shown that there is a heritable component to gene expression variation, and have identified genomic regions that contain polymorphic regulators. However, most of these regions are quite large, and few regulators have been identified. In this genetic of gene expression study, we used a large sample to search the genome for polymorphic regulators that influence gene expression, and followed up the results with deep sequencing of transcriptomes and molecular analyses. Key word(s): Transcriptome Analysis genetics of gene expression study, 41 Coriell cell line samples examined.
