Project description:Tire-wear particles (TWPs) are considered among the largest contributors of microplastics to the environment. They are subject to break-down due to environmental weathering, which allows for potentially toxic chemicals to be leached from and sorbed onto the particles. In this study, leachate generated from “weathered” and “un-weathered” TWPs were used for sublethal toxicity tests with Americamysis bahia.

Project description:Recently, omics techniques have been widely applied to the discovery of potential bio-markers and explore triggering mechanism. To get a more comprehensive diagnosis of HBCD impacts on marine medaka (Oryzias melastigma), the larvae (within 24 hours post-hatch) were exposed to gradient doses of HBCD. After exposure for 7 days, the profiles of genes expression were examined using a custom-commercial 26, 430-oligonucleotide arrays (4M-CM-^W44K) of Japanese medaka which is shared much genomic information with marine medaka.At the end of the treatment period, 30 larvae/sample were pooled for RNA extraction and labeled by One-Color. A total of twelve independent arrays: three control (DMSO), three low-concentration HBCD (0.2 nM) exposures, three medium-concentration HBCD (2 nM) exposures, and three high-concentration HBCD (20 nM) exposures. The larvae of marine medaka (within 24 hours post-hatch) were exposed to to 0 (control), 0.2nM, 2nM and 20nM of HBCD (dimethyl sulfoxide with a final concentration of 1:30000 v/v water) for 7 days. Each HBCD treatment had three replicates with 100 larvae for each Petri dish. At the end of the treatment period, 30 larvae/sample were pooled for RNA extraction. A total of twelve independent arrays: three control (DMSO), three low-concentration HBCD (0.2 nM) exposures, three medium-concentration HBCD (2 nM) exposures, and three high-concentration HBCD (20 nM) exposures.

Project description:We sequenced mRNA extracted from brains of (1) D. melanogaster larvae exposed to food containing 5% ethanol (v/v) for 6 conscutive days, and (2) an age-matched untreated control larvae, that grew in regular food. Differential gene expression between the two groups was calculated and reported. Each group consisted of 3 biological replicates of 30 brains each.

Project description:This dataset contains results for a semi-untargeted metabolomics study on fungal metabolite identification of the tire wear compounds acetanilide and hexamethoxymethylmelamine. High-resolution Orbitrap mass spectrometry was used along with Compound Discoverer (version 3.1) for downstream analysis. Further information is available in the readme file and related publication.

Project description:Phthalates are added to polymers in order to increase their flexibility, but leach out of the matrix. Given that these plasticizers are mainly found in water bound to particles, aquatic species are exposed to phthalates. Silurana tropicalis eggs were exposed to high concentrations of three pththalates: dicyclohexyl phthalate (DCHP; 19 mg/L), dimethyl phthalate (DMP; 34 mg/L), and monomethyl phthalate (MMP; 1500 mg/L), along to their respective controls: 0.82% DMSO for DCHP, and water controls for DMP and MMP. The exposure lasted 3 days during embryogenesis. Four pooled of 10 larvae were sampled per treatment and analyzed for gene expression changes using a microarray approach.

Project description:ngs2014_07_hevea-hevea_tpd-seq-RNAseq analysis of latex samples from healthy and Tapping Panel Dryness-affected trees.-Identification of Tapping Panel Dryness (TPD)-affected trees in a polyclonal trials grown under standard condition. Trees were tapped since November 2010 every 2 days. Latex yield and TPD occurrence were monitored as well as latex RNA samples were collected twice a year for further analysis. At the end of the experiment, gene expression in latex of healthy and TPD trees were compared.
