Gene expression profiling of fathead minnows (Pimephales promelas) following an acute exposure to pulp and paper mill effluents

ABSTRACT: We evaluated the possible mechanisms by which exposure to a sequentially treated pulp and paper mill effluent affects gene expression in the liver of male and female fathead minnows. Sexually mature fathead minnows were exposed to either river water, which served as our control (C), 10% untreated kraft effluent (UTK), 25% treated kraft effluent (TK) or 100% final effluent (CMO) from a multiprocess pulp and paper mill for 6 days. A total of 4 treatments. Each exposure aquarium consisted of a 42.1 L column that contained individual 5.3 L chambers. Each chamber contained a FHM breeding pair. A total of 3 biological replicates for male and female FHM per treatment were sent for microarray analysis resulting in a total of 24 arrays run as a reference design with a pooled sample of the 6 river water exposed fish serving as the reference sample..

Effects of pulp and paper mill effluents on gene expression in the fathead minnow hypothalamus

Project description:We evaluated the possible mechanisms by which exposures to pulp and paper mill effluents gene expression in the fathead minnow hypothalamus Keywords: Toxicology Sexually mature fathead minnows were exposed to 100% pulp and paper mill effluents for 5 days. Tanks contained 4 females and 2 males. A total 4 tanks per effluents were used in this experiment. TM5, TM6, and KM4 represent different pulp and paper mill effluents from different mills coded for by FPInnovations-Paprican.

Exposure of Feathead Minnows to Municipal Wastewater Effluent Inhibits the Canonical Wnt Signaling Pathway in the Liver

Project description:Municipal wastewater effluent can impact its receiving environment. In the St. Lawrence River, male fish living downstream from Montreal exhibit increased hepatic vitellogenin, intersex, delayed spermatogenesis and altered immune function. Few studies have examined genome-wide effects associated with municipal effluent exposure in fish to decipher the mechanisms of toxicity. The present objective was to identify hepatic cellular signaling pathways in fathead minnows following exposure to municipal wastewater effluent. Immature minnows were exposed for 21 days to either 0% (Control) or 20% municipal effluent, the highest concentration in the St. Lawrence River. Hepatic RNA was extracted and used to hybridize a fathead minnow oligonucleotide microarray containing approximately 15K gene sequences.

Evaluating the endocrine disrupting impacts of paper mill exposure on the Eastern Mosquitofish (Gambusia holbrooki) by gene expression analysis

Project description:Masculinized female Eastern Mosquitofish (Gambusia holbrooki) have resided downstream of paper mills in Florida since the 1980's. The potential impacts of this effluent on the mosquitofish endocrine system are unknown. The objective of this study was to evaluate gene expression patterns of endocrine system genes and global gene expression patterns in female G. holbrooki from a paper mill-impacted site. Masculinized female G. holbrooki were collected from a paper mill-impacted site (Fenholloway River) and from a reference site (Econfina River) and microarray analysis in livers was conducted. Hepatic microarray analysis revealed an increase in the expression of metabolic genes at the Fenholloway, with similarities in individual genes and biological processes compared to G. holbrooki exposed to androgens. These data indicate G. holbrooki from the Fenholloway may be impacted by a mixture of endocrine-active chemicals, including androgens.

Assessment of Endocrine Disruption in the Shenandoah River Watershed – Transcriptome Data from Mobile Laboratory Fish Exposures and Other Experiments Conducted during 2014

Project description:Here, we employed integrated chemical and biological analyses to determine how environmental mixtures affected biological responses in watersheds with different landuse. Adult male fathead minnows (Pimephales promelas) were exposed to water from different locations within the Shenandoah River watershed (VA, USA) in 2014, 2015, and 2016. The exposure locations were chosen to capture unique landuse in surrounding watersheds, including agricultural, municipal, mixed-use, and forested sites. Gene expression profiles were measured in livers of male fish exposed for 7 days using Agilent 60K custom FHM microarrays.
