The molecular response to hypoxia stress in aquatic invertebrates remains relatively unknown. In this study, we investigated the response of the Pacific oyster Crassostrea gigasto hypoxia under experimental conditions and focused on the analysis of the differential expression patterns of specific genes associated with hypoxia response. A suppression subtractive hybridiza-tion method was used to identify specific hypoxia up- and downregulated genes, in gills, mantle and digestive gland, after 7–10 days and 24 days of exposure....

Calcium metabolism in oysters is a very complicated and highly controlled physiological and biochemical process. However, the regulation of calcium metabolism in oyster is poorly understood. Our previous study showed that calmodulin (CaM) seemed to play a regulatory role in the process of oyster calcium metabolism. In this study, a full-length cDNA encoding a novel calmodulin-like protein (CaLP) with a long C-terminal sequence was identi-fied from pearl oysterPinctada fucata, expressed in Escherichia coliand characterizedin vitro. ...

The effects of pesticide contamination on the metabolism of marine mol-luscs are poorly documented. We investigated the response of a marine bivalve, the Pacific oyster,Crassostrea gigas, using a suppression subtrac-tive hybridization method to identify up- and down-regulated genes after a 30-day exposure period to herbicides (a cocktail of atrazine, diuron and isoproturon, and to the single herbicide glyphosate). A total of 137 unique differentially expressed gene sequences was identified, as well as their asso-ciated physiological process....

Metallothioneins are typically low relative molecular mass (6000–7000), sulfhydryl-rich metal-binding proteins with characteristic repeating cysteine motifs (Cys-X-Cys or Cys-Xn-Cys) and a prolate ellipsoid shape containing single a-andb-domains. While functionally diverse, they play important roles in the homeostasis, detoxification and stress response of metals. The originally reported metallothionein of the American oyster,Crassostrea virginicashowed the canonical molluscanab-domain structure. ...

We found a novel 52 kDa matrix glycoprotein MPP1 in the shell ofCras-sostrea nippona that was unusually acidic and heavily phosphorylated. Deduced from the nucleotide sequence of 1.9 kb cDNA, which is likely to encode MPP1 with high probability, the primary structure of this protein shows a modular structure characterized by repeat sequences rich in Asp, Ser and Gly.

Groups of oysters (Crassostrea gigas) were exposed to 25C for 24 days (controls to 13 C) to explore the biochemical and molecular pathways affected by prolonged thermal stress. This temperature is 4C above the summer seawater temperature encountered in western Brittany, France where the animals were collected.

The mollusk shell is a hard tissue consisting of calcium carbonate and organic matrices. The organic matrices are considered to play important roles in shell formation. We have previously identified a prismatic layer-specific protein named Prismalin-14, which consists of 105 amino acid resi-dues and includes four structurally characteristic regions;

This study investigated the potential of RNA interference, which is techni-cally challenging in bivalve mollusc species, to assess gene function in the oysterCrassostrea gigas. We designed dsRNA targeting the oyster vasa-like gene (Oyvlg), specifically expressed in oyster germ cells. In vivoinjection of oyvl-dsRNA into the gonad provokes a knockdown phenotype correspond-ing to germ cell underproliferation and prematurely arrested meiosis throu-gout the organ.
