A shining starlet: Nematostella vectensis as a model for developmental, regenerative, and comparative biology

Developmental Dynamics, EarlyView.
Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

A systematic 15N‐amino‐acid tracer framework to identify sources of pelagic marine organic matter

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurately tracing organic matter sources in marine systems remains challenging, particularly where natural and anthropogenic inputs coexist. Compound‐specific stable isotope analysis of amino acids (CSIA‐AA) offers strong potential for organic matter source discrimination, but its application is limited by the small number of validated δ15N ...

A putative nursery pollination mutualism between Japanese Chrysosplenium plants and Nipponorhynchus sawflies

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding ecological interactions is increasingly important for biodiversity conservation. This study reveals a unique nursery pollination mutualism between Japanese endemic plants and sawflies. These partners exhibit tightly synchronized life cycles in riparian forests, making them sensitive to environmental changes.

Insights into the lifestyle and preservation of Arenactinia ipuensis n. gen. et n. sp. (Anthozoa, Actiniaria) from the Early Silurian (Ipu Formation, Parnaíba Basin, Brazil)

Earth History and Biodiversity
Soft-bodied cnidarians are scarce in the fossil record and only a few sea anemones are documented in Paleozoic, mainly in Konservat Lagerstätten. We present a new cnidarian taxon exhibiting wide intraspecific morphological diversity: Arenactinia ipuensis

Betulinic Acid Enema Alleviates Colitis by Targeting Vitamin D Receptor to Protect the Intestinal Mucosal Barrier and Modulate Mucosa‐Associated Microbiota

Phytotherapy Research, EarlyView.
ABSTRACT Ulcerative colitis (UC) is a chronic inflammatory disease of the colon with limited effectiveness and safety of current drug therapies. Betulinic acid (BA) is a naturally occurring pentacyclic triterpenoid present in traditional Chinese medicines used clinically as retention enemas for UC, but its direct effects and mechanisms remain unclear ...

Interactions among sea anemones, their algal endosymbionts, and associated communities on California rocky intertidal shores [PDF]

, 2021
Sea anemones in the genus Anthopleura are conspicuous community members on California rocky shores. They live symbiotically with algae and exchange nitrogen for photosynthetically derived sugars and lipids. The mutualism between host and endosymbiont has
