Disease relevance of Corbicula

• The aim of this work was to evaluate the potential utility of several biochemical parameters as indicators of the toxic effects of cadmium in the freshwater clam Corbicula fluminea under two levels of oxygenation (normoxia 21 kPa and hypoxia 4 kPa) [1].
• Acute toxicity, toxicokinetics, and tissue target of lead and uranium in the clam Corbicula fluminea and the worm Eisenia fetida: comparison with the fish Brachydanio rerio [2].

High impact information on Corbicula

• Kinetic properties and structural characteristics of an unusual two-domain arginine kinase of the clam Corbicula japonica [3].
• We expressed three mutants of Corbicula AK domain 2 (His-60 to Gly or Arg, Asp-197 to Gly), and determined their K m arg and Vmax values [3].
• When rats were fed for 2 weeks on 3% fat diets containing 0.5 or 1%corbicula (Corbicula japonica PRIME), clam (Tapes japonica) or oyster (Callocorchina) triglycerides, serum and liver triglyceride levels were significantly lowered [4].
• Each dietary group was further divided into subgroups whose diet contained 0, 5 or 10% (dry weight) of minced corbicula (Corbicula japonica Prime) [5].
• Though corbicula contains several sterols, sterols other than cholesterol were almost not absorbed [5].

Biological context of Corbicula

• Increased genotoxicity of acetylaminofluorene by modulators of multixenobiotic resistance mechanism: studies with the fresh water clam Corbicula fluminea [6].
• (iii) Arsenic concentrations in Corbicula from perennial flow reaches of the San Joaquin River varied directly with the HNO3-extractable (pH 2) As:Fe ratio of suspended matter, providing evidence that sorption to oxyhydroxide surfaces is an important control on the biological availability of As [7].
• Tissue distribution of inorganic mercury, methylmercury and cadmium in the Asiatic clam (Corbicula fluminea) in relation to the contamination levels of the water column and sediment [8].
• A set of experiments was performed to investigate the bioavailability and the effect of Se on the ventilatory activity of the bivalve Corbicula fluminea, under different conditions of both algal cell densities and dissolved Se chemical forms and concentrations [9].
• To establish the phylogenetic position of Xenophyophorea, we analysed the small subunit (SSU) rRNA gene sequence of Syringammina corbicula Richardson, a newly described xenophyophorean species from the Cape Verde Plateau [10].

Associations of Corbicula with chemical compounds

• Serum and liver triglyceride levels were significantly reduced by feeding corbicula meat in all the dietary groups [5].
• Activities of glucose-6-phosphate dehydrogenase, malic enzyme and acetyl-CoA carboxylase were also markedly reduced by feeding corbicula [5].
• Opsonizing and agglutinating activities of plasma from the freshwater clam, Corbicula fluminea, were found to be inhibited by the sugars, 2-deoxy-D-glucose (deoxy-Glu) and N-acetyl-D-galactosamine (GalNAc) [11].
• The study was performed in the Asiatic clam Corbicula fluminea and applied to cadmium [12].
• Laboratory experiments were carried out to analyze the first valve closure response of a freshwater bivalve (Corbicula fluminea) exposed to uranium during a 5-h period [13].

Gene context of Corbicula

• The presence of a 'multixenobiotic resistance' [MXR] mechanism in gills of the freshwater clam Corbicula fluminea was investigated [6].
• Phylogenetic analyses of the COI dataset revealed that Corbicula members are subdivided into two well-supported clades: estuarine and freshwater [14].
• To understand the unusual polar body formation in the androgenetic clam, Corbicula leana, whole-mount eggs stained with monoclonal antibodies against alpha-tubulin, gamma-tubulin, and 4'-6'-diamidino-2-phenylindole were examined [15].
• Mean Cd and Cu concentrations in Corbicula were elevated in the Merced and Tuolumne Rivers, Orestimba Creek and a perennial flow reach of the San Joaquin River which receives water directly from the Delta Mendota Canal [7].
• Carotenoids in three species of Corbicula Clams, Corbicula japonica, Corbicula sandai, and Corbicula sp. (Chinese Freshwater Corbicula Clam) [16].
