Project description:In this project we aimed to establish a proteome-based pipeline for a non-model Baikal endemic amphipod species Eulimnogammarus cyaneus (Dybowsky, 1874). We used next-generation transcriptome sequencing to create a database for protein identification and investigated the proteome of E. cyaneus with LC-MS with particular emphasis on sexual dimorphism and response to acute thermal stress. We were able to characterize ca. 1000 protein groups and found male- and female-specific proteins, as well as proteins specific for thermal stress conditions.

Project description:Despite the fact that deep sea mining is becoming more popular nowadays in terms of obtaining metals ores for daily life purposes, its potential impact to the deep sea habitat, which is originally stable and converse, stills remains uncertain. In order to estimate and regulate the imapct of deep sea mining activities, an in-situ exposure experiment is performed to observe the change in proteomics expression of the deep-sea scvangers, Abyssorchomene distinctus, to copper exposure. This project aims to suggest a potenial protein bio-marker in Abyssorchomene distinctus to assess the impact of mining activities towards deep sea organisms and also discuss the potential application of other deep sea in-situ exposure experiment in the future.

Project description:modENCODE_submission_3082 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq.

The resulting plasmid was used for biolistic transformation of an unc-119(ed3) strain. The SEA-2::EGFP fusion protein is expressed in the correct sea-2 spatio-temporal expression pattern. This strain was used for ChIP-seq experiments to map the in vivo binding sites for the SEA-2 transcription factor. made_by : ); Developmental Stage: L3; Genotype: unc-119(ed3); wgIs193(sea-2::TY1 EGFP FLAG C; unc-119); Sex: Hermaphrodite; EXPERIMENTAL FACTORS: Developmental Stage L3; Target gene sea-2; Strain OP193(official name : OP193 genotype : unc-119(ed3); wgIs193(sea-2::TY1 EGFP FLAG C; unc-119) outcross : 3 mutagen : Bombard tags : GFP::3xFlag description : This strain's transgene was constructed by Mihail Sarov at the Max Planck Institute for Cell Biology in Tubiginen using Tony Hyman's recombineering pipeline.

Project description:The sea cucumber Apostichopus japonicus withstands high water temperatures in the summer by suppressing metabolic rate and entering a state of aestivation. We hypothesized that changes in the expression of miRNAs could provide important post-transcriptional regulation of gene expression during hypometabolism via control over mRNA translation. The present study analyzed profiles of miRNA expression in the sea cucumber respiratory tree using Solexa deep sequencing technology. We identified 279 sea cucumber miRNAs, including 15 novel miRNAs specific to sea cucumber. Animals sampled during deep aestivation (DA; after at least 15 days of continuous torpor) were compared with animals from a non-aestivation (NA) state (animals that had passed through aestivation and returned to an active state). We identified 30 differentially expressed miRNAs ([RPM (reads per million) >10, |FC| (|fold change|) ≥1, FDR (false discovery rate) <0.01]) during aestivation, which were validated by two other miRNA profiling methods: miRNA microarray and real-time PCR. Among the most prominent miRNA species, miR-124, miR-124-3p, miR-79, miR-9 and miR-2010 were significantly over-expressed during deep aestivation compared with non-aestivation animals, suggesting that these miRNAs may play important roles in metabolic rate suppression during aestivation.
