Geographic structure in the Southern Ocean circumpolar brittle star Ophionotus victoriae (Ophiuridae) revealed from mtDNA and single‐nucleotide polymorphism data
Marine systems have traditionally been thought of as "open" with few barriers to gene flow. In particular, many marine organisms in the Southern Ocean purportedly possess circumpolar distributions that have rarely been well verified. Here, we use the highly abundant and endemic Southern Ocean brittle star Ophionotus victoriae to examine genetic structure and determine whether barriers to gene f...
متن کاملExpression of skeletogenic genes during arm regeneration in the brittle star Amphiura filiformis☆
The brittle star Amphiura filiformis, which regenerates its arms post autotomy, is emerging as a useful model for studying the molecular underpinnings of regeneration, aided by the recent availability of some molecular resources. During regeneration a blastema initially is formed distally to the amputation site, and then a rapid rebuild is obtained by adding metameric units, which will eventual...
متن کاملHabitat Distribution and Comparison of Brittle Star (Echinodermata: Ophiuroidea) Arm Regeneration on Moorea, French Polynesia
Autotomy and regeneration are widespread in many groups of invertebrates and vertebrates, such as annelids, crustaceans, amphibians, and reptiles. Regeneration is common in all classes of Echinodermata and prevalent in ophiuroid brittle stars. Moorea, French Polynesia was surveyed for species of brittle stars living on coastal areas of the island in different habitats. Ophiuroid populations wer...
متن کاملThe Anti-Proliferative and Anti-Angiogenic Effect of the Methanol Extract from Brittle Star
Background: Anti-angiogenic therapy is a crucial step in cancer treatment. The discovery of new anti-angiogenic compounds from marine organisms has become an attractive concept in anti-cancer therapy. Because little data correlated to the pro- and anti-angiogenic efficacies of Ophiuroidea, which include brittle star, the current study was designed to explore the anti-angiogenic potential of bri...
متن کاملThe regenerative properties of the extracted polysaccharide from Brittle star (Ophiocoma erinaceus) on cutaneous wound in male Wistar rat
In traditional medicine, extracts of polysaccharide-containing plants are widely employed for the treatment of cutaneus wounds. The brittle star, as one of marine organisms, encompasses bioactive compounds, which confer the healing potency of damaged arms. The aim of the present study is to investigate the effects of extracted polysaccharide from the Persian Gulf brittle star )Ophiocoma erinace...
