Project description:Alkalinity stress is considered to be one of the major stressors for fish in saline-alkali water. Thus, it is of great significance from both aquaculture and physiological viewpoint to understand the molecular genetic response of aquatic organisms to alkalinity stress. The objective of this study is to determine genome-wide gene expression profiles to better understand the physiology response of medaka (Oryzias latipes) to high carbonate alkalinity stress. In lab-based cultures, adult fish were exposed to freshwater and high carbonate alkalinity water .We designed a microarray containing 26429 oligonucleotides and describe our experimental results for measuring gene expression changes in the gill of carbonate alkalinity stress exposed fish. The fish were exposed to freshwater (FW) and high carbonate alkalinity water (AW) for 96h, each with three replicates.

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:Infectious pancreatic necrosis virus (IPNV) is an aquatic virus that causes acute infection in freshwater and marine fish. The stage-specific expression of TNFα regulates Bad/Bid-mediated apoptosis and RIP1/ROS-mediated secondary necrosis in IPNV-infected fish cells. Using microRNA microarray and real-time quantitative PCR assays, the expression patterns of microRNA were characterized in different replication stages of IPNV or stimulation of LPS.
