TranscriptomicsAssessment of chemical mixtures and ground water effects on Daphnia magna transcriptomics
Small organisms can be used as biomonitoring tools to assess chemicals in the environment. Chemical stressors are especially hard to assess and monitor when present as complex mixtures. Here, Daphnia magna were exposed for 24 hours to five different munitions constituents 2,4,6-trinitrotoluene (TNT)...

TranscriptomicsEffects of a short-term exposure to the fungicide prochloraz on endocrine function and gene expression in female fathead minnows (Pimephales promelas)
Prochloraz is a fungicide known to cause endocrine disruption through effects on the hypothalamic-pituitary-gonadal (HPG) axis. To determine the short-term impacts of prochloraz on gene expression and steroid production, adult female fathead minnows (Pimephales promelas) were exposed to the chemical...

TranscriptomicsGene expression changes in the female zebrafish (Danio rerio) brain in response to acute exposure to methylmercury
Methylmercury (MeHg) is a potent neurotoxin and endocrine disruptor that accumulates in aquatic systems. Previous studies have shown suppression of hormone levels in both male and female fish, suggesting effects on gonadotropin regulation in the brain. We investigated the gene expression profile in ...

TranscriptomicsInfluence of Gross Ovarian Stage on Transcript Profiles in Fathead Minnow (Pimephales promelas) Ovary Tissue
Interpretation of toxicogenomic experiments conducted with ovary tissue from asynchronous-spawning small fish species are complicated by background variation in the relative abundance and proportion of follicles at different stages within the ovary tissue sample. This study employed both real-time ...

TranscriptomicsLinkage of behavioral and genomic impacts of a wastewater effluent on the fathead minnow
Rivers containing effluents from water treatment plants are complex soups of compounds, ranging from pharmaceuticals to natural hormones. Male fathead minnows (Pimephales promelas) were exposed for 3 weeks to effluent waters from the Metropolitan Wastewater Treatment Plant in St. Paul, MN. Fish wer...

TranscriptomicsToxicogenomic analysis of ionic silver and silver nanoparticles on the fathead minnow and implications to human health
Nanoparticles are compounds of emerging concern with largely unknown risks for human and ecological health. It is crucial to evaluate their potential biological impact to prevent unintended adverse effects on human health and the environment. We analyzed the transcriptional effects of polyvinylpyrro...
