TranscriptomicsNickel and binary metal mixtures in Daphnia magna after 96h
The recent development of a custom cDNA microarray platform for one of thé standard organisms in aquatic toxicology, Daphnia magna, opened up new ways to mechanistic insights of toxicological responses. In this study, gene expression and (sub)organismal responses (Cellular Energy Allocation, growt...

TranscriptomicsDevelopment of a microarray for Enchytraeus albidus (Oligochaeta): Preliminary tool with diverse applications
Standard bioassays allow hazard assessment at the population level, but much remains to be learned about the molecular level response of organisms to stressors. The main aim of this study was the development of a DNA microarray for Enchytraeus albidus, a common soil worm species. Further, this micro...

TranscriptomicsEffect of Cu-Nanoparticles versus Cu-salt in Enchytraeus albidus (Oligochaeta): differential gene expression through microarray analysis
Despite the increased utilization of nanoparticles, the behavior and effect in the environment is largely unknown and few resources are available for health and environmental effect studies. Enchytraeids are extensively used in studies of soil ecotoxicology and recently, a cDNA microarray for Enchyt...

TranscriptomicsGene transcription profiles and potential transgenerational epigenetic effects related to Zn exposure history in Daphnia magna
A reduced level of DNA methylation has recently been described in both Zn-exposed and non-exposed offspring of Daphnia magna exposed to Zn. The hypothesis examined in this study is that DNA hypomethylation has an effect on gene transcription. A second hypothesis is that accumulative epigenetic effec...

TranscriptomicsDifferential gene expression analysis in Enchytraeus albidus exposed to natural and chemical stressors at different exposure periods
The soil oligochaete Enchytraeus albidus is a standard test organism used in biological testing for Environmental Risk Assessment (ERA). Although effects are known at acute and chronic level, through survival, reproduction and avoidance behaviour endpoints, very little is known at the sub-cellular a...

TranscriptomicsD. magna exposed to fluoranthene and pyrene - both as single compounds and binary mixtures
Daphnia are an important and widely studied model species in ecological and toxicological studies throughout the world and an official (OECD) recommended test organism. Their small size, wide distribution and easy growth conditions make this an organism ideal for functional genomics based studies, i...
