Active Notch signaling is required for arm regeneration in a brittle star. [PDF]
PLoS One, 2020 Cell signaling pathways play key roles in coordinating cellular events in development. The Notch signaling pathway is highly conserved across all multicellular animals and is known to coordinate a multitude of diverse cellular events, including ...

One-pot green synthesis of silver nanoparticles using brittle star Ophiocoma scolopendrina: Assessing biological potentialities of antibacterial, antioxidant, anti-diabetic and catalytic degradation of organic dyes. [PDF]
Heliyon, 2023 In the current study, aqueous extract of O. scolopendrina (OSE) was used to synthesize AgNPs in a simple and environmentally friendly manner. The biosynthesized OSE-AgNPs were also assessed for its catalytic, antibacterial, anti-diabetic, antioxidant and

<i>Youngimonas ophiurae</i> sp. nov., a Quorum-Quenching Marine Bacterium Isolated from a Brittle Star in the South China Sea, and Reclassification of <i>Lutimaribacter litoralis</i> as <i>Youngimonas litoralis</i> comb. nov. [PDF]
MicroorganismsTwo novel bacterial strains, designated S70T and S69A, were isolated from a marine brittle star collected in the South China Sea. These strains are Gram-stain-negative, non-motile, aerobic, and rod-shaped.

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star <i>Gymnolophus sexradia</i> sp. Nov. [PDF]
Ecol EvolThe brittle star of genus Gymnolophus Brock, 1888 (Ophiuroidea: Ophiotrichidae Ljungman, 1867) is commonly found in epizoic relationships with crinoid hosts, such as Comaster schlegelii (Crinoidea: Comatulidae Fleming, 1828), benefiting from food and ...

Genetic variation in the brooding brittle-star: a global hybrid polyploid complex? [PDF]
R Soc Open SciThe widespread and abundant brooding brittle-star (Amphipholis squamata) is a simultaneous hermaphrodite with a complex mitochondrial phylogeography of multiple divergent overlapping mtDNA lineages, high levels of inbreeding or clonality and unusual ...

Sequencing and analysis of the gastrula transcriptome of the brittle star
EvoDevo, 2012 Background The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states ...

A puzzling homology: a brittle star using a putative cnidarian-type luciferase for bioluminescence. [PDF]
Open Biol, 2017 Bioluminescence relies on the oxidation of a luciferin substrate catalysed by a luciferase enzyme. Luciferins and luciferases are generic terms used to describe a large variety of substrates and enzymes.
