Extraction, Characterization and Osteogenic Activity of a Type I Collagen from Starfish (Asterias amurensis)

Marine Drugs, 2023
Outbreaks of starfish (Asterias amurensis) pose a major threat to aquaculture and marine ecosystems in Qingdao, China, and no effective methods have been found to control them. A comprehensive study of collagen in starfish could be an alternative to high

An exceptionally well-preserved starfish fauna (Asteroidea, Echinodermata) from the Early Miocene of southeastern France [PDF]

Swiss Journal of Palaeontology
A new starfish fauna from the Late Burdigalian (Early Miocene) of the Apt basin (Rhodano-Provençal gulf, southeastern France) is described here. This new starfish fauna comes from accumulation levels of marine invertebrates, including exceptionally well ...

Structural analysis of the starfish SALMFamide neuropeptides S1 and S2: The N-terminal region of S2 facilitates self-association [PDF]

, 2014
The neuropeptides S1 (GFNSALMFamide) and S2 (SGPYSFNSGLTFamide), which share sequence similarity, were discovered in the starfish Asterias rubens and are prototypical members of the SALMFamide family of neuropeptides in echinoderms.
