Expression of P-glycoprotein in southeastern oysters, Crassostrea virginica

Marine Environmental Research, 2001
These studies provide important fundamental information regarding the expression of P-glycoprotein (p-gp) in southeastern oysters (Crassostrea virginica). Using rhodamine transport studies, p-gp activity was detected in newly fertilized embryos. A monoclonal antibody (C219) was used to evaluate p-gp expression in oyster tissues.

Ultrastructure of the spermatozoon of the oyster, Crassostrea virginica

Journal of Ultrastructure Research, 1960
Electron microscopy reveals the presence in oyster sperm of an axial body, a massive structure extending from the proximal area of the nucleus to the top of the acrosome. The location and structure of this body suggests that it is concerned with the formation and extrusion of the acrosome filament as described for several invertebrates.

Accumulation of cadmium by the American oyster, Crassostrea virginica

Nature, 1976
CADMIUM is a major environmental pollutant potentially harmful to health, and if the sea becomes polluted with this metal there could be a reduction in extensive sources of food1. Seafoods constitute a source of cadmium in the human diet2 and in view of abundant evidence that shellfish accumulate trace metals3–6, it is important to investigate cadmium ...

Seasonal variation in lysosomal destabilization in oysters, Crassostrea virginica

Marine Environmental Research, 2002
Lysosomal destabilization assays have been used as valuable biomarkers of pollutant exposures in a variety of bivalve and fish species. The responses of oysters, Crassostrea virginica, deployed at and native to various reference and degraded sites were evaluated for lysosomal destabilization during both summer and winter seasons.

Crassostrea virginica as an indicator of lead pollution

Marine Biology, 1979
After treatment with 1.0 and 3.3 μg Pb kg-1 for 20 weeks in flowing seawater at ambient salinity and temperature, Crassostrea virginica accumulated as much as 6.57 and 11.42 μg g-1 dry weight, respectively, and no mortalities were recorded. Lead uptake was curvilinear; however, the general trend was an increase in lead concentration over time.

Zinc Enzymes inCrassostrea virginica

Journal of the Fisheries Research Board of Canada, 1970
Nearly all the zinc in oysters is bound, either to soluble high-molecular weight proteins or to structural cellular components such as cell membranes. Oyster alkaline phosphatase is a zinc metalloenzyme, as indicated by in vitro inhibition studies with various metal-binding agents.

Characteristics of Crassostrea virginica crystalline style chitin digestion

Comparative Biochemistry and Physiology Part A: Physiology, 1986
Abstract 1. 1. Fundamental chitin digestion characteristics of Crassostrea virginica crystalline style were investigated. 2. 2. Optimum temperature and pH were 34°C and 4.8. respectively. 3. 3. The colloidal regenerated chitin (0.56mol/0.5 ml: GlcNAc equivalents) was saturating under all enzyme levels encountered. 4. 4. There was no

Hemagglutinin in the blood of the oyster Crassostrea virginica

Journal of Invertebrate Pathology, 1966
Abstract A protein in the blood of normal oysters ( Crassostrea virginica ) agglutinates red blood cells of several vertebrate species. Adsorption tests indicate that this material has a moderate degree of specificity. It exerts an opsonic effect on rabbit red blood cells in vitro and probably influences the rate of phagocytosis of red cells and ...
