Oyster reproduction is affected by exposure to polystyrene microplastics
TLDR
Evidence is provided that micro-PS cause feeding modifications and reproductive disruption in oysters, with significant impacts on offspring, providing ground-breaking data on microplastic impacts in an invertebrate model, helping to predict ecological impact in marine ecosystems. Expand
Oyster vasa-like gene as a marker of the germline cell development in Crassostrea gigas.
TLDR
It is postulate that the germline of C. gigas is specified at early development by maternal cytoplasmic determinants including Oyvlg mRNAs, in putative PGCs that would differentiate into germinal stem cells in juvenile oysters. Expand
Temperature and photoperiod drive Crassostrea gigas reproductive internal clock
TLDR
The gametogenic cycle of Crassostrea gigas was examined in controlled conditions over one year, with a focus on the initiation of gametogenesis, and the role of temperature and photoperiod in the regulation of oyster reproduction was analysed. Expand
Exposure of marine mussels Mytilus spp. to polystyrene microplastics: Toxicity and influence on fluoranthene bioaccumulation.
TLDR
Results suggest that under the experimental conditions of this study micro-PS led to direct toxic effects at tissue, cellular and molecular levels, and modulated fluoranthene kinetics and toxicity in marine mussels. Expand
Cellular and molecular hemocyte responses of the Pacific oyster, Crassostrea gigas, following bacterial infection with Vibrio aestuarianus strain 01/32.
TLDR
The interactions between the Pacific oyster immune system and Vibrio aestuarianus strain 01/32, a pathogenic bacterium originally isolated from moribund oysters, are investigated, providing new insights into the cellular and molecular bases of the host-pathogen interactions in C. gigas oyster. Expand
The oyster vasa-like gene: a specific marker of the germline in Crassostrea gigas.
TLDR
Oyvlg is the first germ cell specific marker in oyster and will be very useful in studies of oyster germline formation. Expand
Microplastics in seafood: Benchmark protocol for their extraction and characterization.
TLDR
The protocol using a KOH 10% solution and incubation at 60 °C during a 24 h period led to an efficient digestion of biological tissues with no significant degradation on all tested polymers, except for cellulose acetate. Expand
Interactions between microplastics and phytoplankton aggregates: Impact on their respective fates
TLDR
The results clearly show that marine aggregates can be an efficient sink for microplastics by influencing their vertical distribution in the water column, and opens new questions regarding the impact of plastics on sedimentation fluxes in oceans. Expand
Evidence in oyster of a plasma extracellular superoxide dismutase which binds LPS.
TLDR
The purified Cg-EcSOD was shown to bind to oyster hemocytes and to be immunocolocalized with a beta-integrin-like receptor and to display an affinity to Escherichia coli bacteria and with LPS and Lipid A. Expand
Influence of environmental and anthropogenic factors on the composition, concentration and spatial distribution of microplastics: A case study of the Bay of Brest (Brittany, France).
TLDR
The presence of buoyant microplastics (PE, PP and PS) in sediment suggests the existence of physical and/or biological processes leading to vertical transfer of lightweight microplastic in the Bay of Brest, and it is suggested that the observed spatial MP distribution is related to proximity to urbanized areas and to hydrodynamics in the bay.
