Discoveries of FHL EIMD Course Published

This week the manuscript “Development of Genomic Resources for a thraustochytrid Pathogen and Investigation of Temperature Influences on Gene Expression” was published.   Photo: Students in FHL EIMD course hard at work on bioinformatic analysis of transcriptome and genomic data from the hard clam pathogen quahog parasite unknown (QPX).   Abstract: Understanding how environmental changes influence the pathogenicity and virulence of infectious agents is critical for predicting epidemiological patterns of disease. Thraustochytrids, part of the larger taxonomic...

Shotgun proteomics and the Pacific oyster

Emma’s paper on shotgun proteomics was recently  published where she describes the value of shotgun proteomics in physiological studies. Timmins-Schiffman EB* Nunn BL, Goodlett DR and Roberts SB. (2013) Shotgun proteomics as a viable approach for biological discovery in the Pacific oyster. Conservation Physiology. doi:10.1093/conphys/cot009   Abstract: Shotgun proteomics offers an efficient means to characterize proteins in a complex mixture, particularly when sufficient genomic resources are available. In order to assess the practical application of shotgun proteomics in the...

Genomic resource development for shellfish of conservation concern

We recently published the sequenced transcriptomes (suite of expressed genes) of pinto abalone and Olympia oyster in the journal Molecular Ecology Resources. The focus of this study was to identify genomic resources to aid conservation efforts for these two native shellfish species. Historic commercial exploitation has depleted native populations of pinto abalone and Olympia oyster along the west coast of the United States. Habitat degradation and climate change have contributed towards inhibited recovery of both species. A better understanding of the species’ transcriptomes and genomes...

Environmental stress can influence Hsp70 expression in a discordant fashion

In this month’s issue of the Journal of Shellfish Research, results from a research project carried out in the lab section of FISH441: Integrative Environmental Physiology was published. David Metzger, a recent graduate from our lab, is the first author on the paper entitled: Characterizing the Effects of Heavy Metal and Vibrio Exposure on Hsp70 Expression in Crassostrea gigas Gill Tissue. Not only does this work demonstrate a role of HSPs in metal exposure, but nicely demonstrates that gene expression and protein expression can be inconsistent. An excerpt from the manuscript: This...

Could lipid content in shellfish diet impact immune signaling?

Most people might only associate ceramide with a key ingredient in hand lotion, however Emma Timmins-Schiffman’s recent paper “Characterization of genes involved in ceramide metabolism in the Pacific oyster (Crassostrea gigas)” sheds light on a role for ceramide in responding to stress. Specifically, Emma examined the role of ceramide in adult oysters’ physiological response to being experimentally challenged with the pathogenic bacteria, Vibrio vulnificus. Two genes demonstrated increased expression during the bacterial challenge: a gene involved in hydrolytic...
