The coelomocytes of the sea urchin, Strongylocentrotus droebachiensis, may be prevented from clotting with 50 mM ethylene glycol-bis(beta-aminoethyl)-N,N,N',N'-tetraacetate, 50 mM Tris-HCl, pH 7.8 and subsequently separated into various cell types on sucrose gradients. One cell type, the petaloid coelomocyte, spontaneously undergoes a striking morphological transformation to a form exhibiting ...
The present study aimed to evaluate the effects of endogenous compared commercial probiotics on growth, digestive enzyme activity, and non-specific immunity sandfish juveniles. Treatments were: A. diet without probiotic; B. supplemented with Gamma proteobacterium strain M-4, Bacillus subtilis Q-1, sp. E-2; C. a probiotic containing subtilis, licheniformis, pumilus. research was conducted for 4 ...
Background: sea urchins belonging to phylum echinoderms of marine invertebrates them found to possess excellent. Diabetes mellitus, metabolic diseases most prevalent in the world with a group of metabolic disorders characterized by different degrees is the first increase in blood glucose levels. The aim of the present research was undertaken to study the anti- diabetes activity of different ext...
The marine environment is becoming increasingly contaminated by environmental pollutants with the potential to damage DNA, with marine sediments acting as a sink for many of these contaminants. Understanding genotoxic responses in sediment-dwelling marine organisms, such as polychaetes, is therefore of increasing importance. This study is an exploration of species-specific and cell-specific dif...
We have isolated a novel type of lectin named Arenicola marina lectin-1 (AML-1) from the lugworm A. marina. The lectin was purified from the coelomic fluid by affinity chromatography on a GlcNAc-derivatized column and eluted with GlcNAc. On SDS-PAGE, AML-1 showed an apparent molecular mass of 27 and 31 kDa in the reduced state. The N-terminal amino acid sequences were identical in these two ban...
Extracts of the soluble cytoplasmic proteins of the sea urchin egg form gels of different composition and properties depending on the temperature used to induce actin polymerization. At temperatures that inactivate myosin, a gel composed of actin, fascin, and a 220,000-mol-wt protein is formed. Fascin binds actin into highly organized units with a characteristic banding pattern, and these actin...
Background: In recent years, there has been a growing interest in the development of sub-lethal earthworm biomarkers as they are relevant indicators of environmental change and they are among the five key indicators for ecotoxicological testing of industrial chemicals determined by the OECD. In the present study, the effects of an organophosphate pesticide dichlorovos on lysosomes of coelomoc...
