Food Modulation Controls Astaxanthin Accumulation in Eggs of the Sea Urchin Arbacia lixula
Marine Drugs, 2018 The carotenoid astaxanthin has strong antioxidant properties with beneficial effects for various degenerative diseases. This carotenoid is produced by some microalgae species when cultivated in particular conditions, and, interestingly, it is a ...

Specification of cell fate in the sea urchin embryo: summary and some proposed mechanisms [PDF]
, 1998 An early set of blastomere specifications occurs during cleavage in the sea urchin embryo, the result of both conditional and autonomous processes, as proposed in the model for this embryo set forth in 1989.

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice
Andrology, EarlyView.ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Antibacterial and Antioxidant Characteristics of Pigments and Coelomic Fluid of Sea Urchin, Echinodermata Mathaei Species, from the Persian Gulf [PDF]
Journal of Kerman University of Medical Sciences, 2015 Background & Aims: Sea urchin immune responses are directly exposed to potentially pathogenic microorganisms and develop defence responses mainly based on immunocytes and humoral factors contained in the coelomic fluid.

EST analysis of gene expression in early cleavage-stage sea urchin embryos [PDF]
, 1999 A set of 956 expressed sequence tags derived from 7-hour (mid-cleavage) sea urchin embryos was analyzed to assess biosynthetic functions and to illuminate the structure of the message population at this stage.

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Conservation Biology, EarlyView.Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...
