Project description:Construction of a comprehensive spectral library for the coral reef fish, Acanthochromis polyacanthus, from both DIA and DDA MS runs. The spectral library was then used to quantify proteomes of individual fish exposed to different environmental conditions including ocean acidification and ocean warming. Proteomes were measured for both liver and brain tissue and differential expression between environmental conditions was analyzed.

Project description:Gills of teleost fish represent a vital multifunctional organ; however, they are subjected to environmental stressors, causing gill damage. Gill damage is associated with significant losses in the Atlantic salmon aquaculture industry. Gill disorders due to environmental stressors are exacerbated by global environmental changes, especially with open-net pen aquaculture (as farmed fish lack the ability to escape those events). The local and systemic response to gill damage, concurrent with several environmental insults, are not well investigated. We performed field sampling to collect gill and liver tissue after several environmental insults. Using a 44K salmonid microarray platform, we aimed to compare the transcriptomes of pristine and moderately damaged gill tissue. The gill damage-associated biomarker genes and associated qPCR assays arising from this study will be valuable in future research aimed at developing therapeutic diets to improve farmed salmon gill health.

Project description:To identify gene expression differences between Oncorhynchus mykiss that migrate and those that reside in freshwater, we compared gill transcriptomes of fish prior to release from a hatchery with those of fish recaptured eight days post-release while all fish were still in freshwater, but some were captured next to the hatchery (non-migrants) and others were captured moving toward the ocean (migrants). The in-hatchery sampling method represents a highly similar environment for all the fish, and allows for the determination of activated genes predictive of smolting programs prior to release into streams. Morphological (e.g. color) and physiological (gill NaCl-ATPase activity) data were also obtained and correlated to gene expression differences to aid in predictions.

Project description:a salmonid microarray was used to characterize environmentally-regulated shifts in gene expression between ocean and river habitats in gill and liver tissues of wild migrating adult Pacific sockeye salmon (Oncorhynchus nerka). To correlate gene expression with survival, non-lethal biopsy sampling of gill tissue and microarray-based profiling was combined with biotelemetry and genetic stock identification so that transcriptomic profiles could be compared between fish reaching spawning grounds and presumed mortalities.

Project description:We develop a method called open chromatin enrichment and network Hi-C (OCEAN-C) for antibody-independent mapping of global open chromatin interactions. By integrating FAIRE-seq and Hi-C, OCEAN-C detects open chromatin interactions enriched by active cis-regulatory elements. We identify more than 10,000 hubs of open chromatin interactions (HOCIs) in human cells, which are mainly active promoters and enhancers bound by many DNA-binding proteins and form interaction networks crucial for gene transcription. In addition to identifying large-scale topological structures including topologically associated domains and A/B compartments, OCEAN-C can detect HOCI-mediated chromatin interactions that are strongly associated with gene expression, super-enhancers and broad H3K4me3 domains.

Project description:a salmonid microarray was used to characterize environmentally-regulated shifts in gene expression between ocean and river habitats in gill and liver tissues of wild migrating adult Pacific sockeye salmon (Oncorhynchus nerka). To correlate gene expression with survival, non-lethal biopsy sampling of gill tissue and microarray-based profiling was combined with biotelemetry and genetic stock identification so that transcriptomic profiles could be compared between fish reaching spawning grounds and presumed mortalities. Fish were captured fish at two marine sampling sites, one within Johnstone Strait (JS), BC. Canada and one within Juan De Fuca Strait (JDFS), BC Canada. Ocean sites were contrasted to fish sampled within the Fraser River at Whonnock (W), BC, Canada. Gill and liver tissues were dissected at each of these sites. Non-lethal biopsy sampling was performed on migrating sockeye salmon intercepted within the Fraser River at Mission, BC, Canada and genetically-based stock ID was used to determine the stock-specific spawning grounds for each fish, giving an intended end-point of migration for each of the stocks investigated in this study.Gene expression levels were determined by comparing the amount of mRNA transcript in the experimental samples relative to a reference sample. A total of 123 microarrays were used to generate the dataset, corresponding to individual hybridizations of both gill and liver samples collected from JS (gill n=14; liver n=15), JDFS (gill n=15; liver n=13), W (gill n=11; liver n=10), and biopsy sampled gill tissue collected at Mission (n=45).Total RNA was amplified (1 round) with MessageAmpTMII-96 kit (Ambion, TX, USA), and reverse transcribed to cDNA before labelling with ALEXA dyes using the Invitrogen Indirect Labelling Kit. The reference contained the combined aRNA of all individuals used in the experiment, excluding bioposy sampled fish. Individual samples were labelled with Alexa 555 and the reference control with Alexa 647, and no dye swaps were perfromed.

Project description:Zebrafish (Danio rerio) were obtained from the Zebrafish Research Facility maintained in the Center for Environmental Biotechnology at the University of Tennessee. Fish husbandry, spawning, and experimental procedures were conducted with approval from the University of Tennessee Institutional Animal Care and Use Committee (Protocol #1690-1007). Water for holding fish and conducting experiments (hereafter referred to as fish water) consisted of MilliQ water (Millipore, Bedford, MA) with ions added: 19 mg/L NaHCO3, 1 mg/L sea salt (Instant Ocean Synthetic Sea Salt, Mentor, OH), 10 mg/L CaSO4, 10 mg/L MgSO4, 2 mg/L KCl. Embryos were obtained by spawning adult fish with no history of contaminant exposure. Fertilization of embryos took place at the same time (± 15 min.), such that larvae used in experiments were of similar age at the time of exposure. All activities (maintenance of adult fish, spawning, and experiments) were conducted in an environmental chamber with a temperature of 27± 1 ºC and 14:10h light:dark photoperiod.
