Selection Over Small and Large Spatial Scales in the Face of High Gene Flow

Molecular Ecology, Volume 34, Issue 6, March 2025.
ABSTRACT Local adaptation represents the balance of selection and gene flow. Increasingly, studies find that adaptation can occur on spatial scales much smaller than the scale of dispersal, resulting in balanced polymorphisms within populations.

Comparative DNA damage and repair in echinoderm coelomocytes exposed to genotoxicants. [PDF]

PLoS ONE, 2014
The capacity to withstand and repair DNA damage differs among species and plays a role in determining an organism's resistance to genotoxicity, life history, and susceptibility to disease.

Effects of silver nanoparticles (NM-300K) on Lumbricus rubellus earthworms and particle characterization in relevant test matrices including soil. [PDF]

, 2014
The impact of silver nanoparticles (AgNP; at 0 mg Ag/kg, 1.5 mg Ag/kg, 15.4 mg Ag/kg, and 154 mg Ag/kg soil) and silver nitrate (AgNO3 ; 15.4 mg Ag/kg soil) on earthworms, Lumbricus rubellus, was assessed.

Properties of sea urchin coelomocyte agglutinins [PDF]

Italian Journal of Zoology, 1996
Abstract We examined some biological activities of a 200‐kDa glyco‐protein, referred to as Paracentrotus lividus vitellogenin, contained both in the coelomic fluid and in a subpopulation of coelomocytes called ≪colourless spherula cells≫. Cell‐free coelomic fluid, coelomocyte lysate and supernatant obtained after coelomocyte washings were assayed for ...

HSP110 is a modulator of amyloid beta (Aβ) aggregation and proteotoxicity

Journal of Neurochemistry, Volume 169, Issue 1, January 2025.
To prevent proteotoxicity, the cell has evolved a proteostasis network comprised of molecular chaperones and proteolytic pathways. HSP110 is a poorly characterized chaperone that has recently been implicated in Alzheimer's disease. In vitro studies have shown that human HSP110 can inhibit Aβ1‐42 fibril formation either alone or with other chaperones ...

Presence and biodistribution of perfluorooctanoic acid (PFOA) in Paracentrotus lividus highlight its potential application for environmental biomonitoring

Scientific Reports, 2021
The first determination of presence and biodistribution of PFOA in ninety specimens of sea urchin Paracentrotus lividus from two differently contaminated sites along Palermo’s coastline (Sicily) is reported.

Potency of Antioxidant Peptides Encrypted in Commercially Important Marine Invertebrates: A Bioinformatics Approach

Journal of Food Biochemistry, Volume 2025, Issue 1, 2025.
Efficient and beneficial food utilization calls for sustainable and innovative practices that add value at every stage of production. In this study, we conducted a computational analysis of protein sequences from the bivalve Mytilus galloprovincialis, the crustacean Penaeus vannamei (whiteleg shrimp), the purple sea urchin Paracentrotus lividus, and ...

The effect of oxidative stress on phagocytosis and apoptosis in the earthworm Eisenia hortensis [PDF]

Invertebrate Survival Journal, 2010
The effect of exogenous hydrogen peroxide (H202) on phagocytic function and apoptosis in coelomocytes from Eisenia hortensis was investigated. Treating coelomocytes with H202 (0.26 to 8.4 mM) evoked a significant increase in phagocytosis for one or more ...

STUDIES ON HOLOTHURIAN COELOMOCYTES. II. THE ORIGIN OF COELOMOCYTES AND THE FORMATION OF BROWN BODIES

The Biological Bulletin, 1965
1. Coelomocyte and brown body production were studied in four species of holothurians, Cucumaria miniata, Eupentacta quinquesemita, Parastichopus californicus, and Psolus chitonoides.2. Available evidence suggests that at least some, if not all, lymphocytes possibly originate from mesenchymal cells in the hemal vessels of holothurians, and possibly ...
