TranscriptomicsTranscription profiling of Daphnia magna treated with: cadmium, pH, lufenuron, calcium limitation and ibuprofen for 24 performed in replicate to assess their effect on stress reponse and growth
Microarray Construction The D. magna microarray was constructed using DNA fragments from three sources: i) Stress-specific cDNAs were generated using Selective Subtractive Hybridisation (SSH) on organisms exposed to the stressors shown in Table 1. SSH was performed with forward and reverse subtrac...

TranscriptomicsGenome-Wide Transcriptional Responses of Nitrosomonas europaea to cadmium
Heavy metals have been postulated as significant nitrification inhibitor in wastewater treatment plant. The effect of heavy metals such as Cd2+, Cu2+ and Hg2+ to nitrifying bacterium, Nitrosomonas europaea, was studied in pseudo-steady state batch reactor. Under incubation of Nitrosomonas europaea w...

TranscriptomicsDepleting cytosolic cysteine compromises the antioxidant capacity of the cytosol in Arabidopsis thaliana
Plant cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes involved in Cys biosynthesis and located in different subcellular compartments. These enzymes are made up of a complex variety of isoforms resulting in different subcellular Cys pools. To unravel the contribution of cytosolic C...

TranscriptomicsTranscriptome Analysis of North Atlantic Right Whale Kidney Fibroblast Cell line exposed to cadmium
An 8X15k oligonucleotide microarray was developed consisting of 2334 E. glacialis probes and 2166 Tursiops truncatus probes and used to measure the transcriptome level effects of right whale kidney fibroblast cells exposed to cadmium. Cells were exposed to three concentrations of cadmium chloride (C...

TranscriptomicsTranscriptome analysis of the WalKR regulon in Staphylococcus aureus
The WalKR regulon was studied by comparing genes expression in a strain producing a constitutively active WalR regulator (WalRc) versus the wild type strain carrying the empty expression vector. Hybridizations were performed with three independent biological replicates. Our data allowed to identify ...

TranscriptomicsGenome-wide profiling of responses to cadmium in the diatom Phaeodactylum tricornutum
The only group of organisms in which a biological function for cadmium has been shown is the diatoms, which are unicellular phytoplankton. Yet diatoms exhibit similar sensitivity to Cd as other groups of phytoplankton. We have investigated responses of Cd on molecular, metabolic and physiological le...

TranscriptomicsEffects of maternal Cd on the female reproductive functions, gametes development and genes expression of zebrafish
The impacts of maternal Cd on zebrafish from female to embryo which included fecundity, gametes development, growth, other reproductive functions, and gene expression of 5hpf embryo were up and down regulated after female pretreated with Cd. The mating rate decreased by 30 %. It can be observed in g...

TranscriptomicsTranscriptome analyses of a C. glabrata strain deleted for the transcription factor Aft2.
In these experiments, we compared the transcriptomes of a wild type strain and an aft2 deleted strain of the pathogenic yeast Candida glabrata. The comparisons were performed in four different growth conditions: iron starvation (BPS treatment), selenite treatment, cadmium treatment and optimal growt...

TranscriptomicsRed algae Gracilaria tenuistipitata: control vs. high copper and high cadmium concentration
The study of macroalgae capacity to acclimate and recover in environments contaminated with Cu and Cd could prove a promising way to understand the tolerance mechanisms of these seaweeds against different pollutants. This study used as a model organism Gracilaria tenuistipitata (Rhodophyta), a macro...
