Functional roles of Notch signaling in the cnidarian Nematostella vectensis [PDF]
Developmental Biology, 2012 Notch signaling is among the oldest of known Metazoan signaling pathways and is used in a multitude of developmental contexts to effect cellular differentiation, specification and the maintenance of stem cell state. Here we report the isolation and expression of the canonical Notch signaling pathway in the early branching metazoan Nematostella ...

Associative learning in the cnidarian Nematostella vectensis. [PDF]
Proc Natl Acad Sci U S A, 2023 The ability to learn and form memories allows animals to adapt their behavior based on previous experiences. Associative learning, the process through which organisms learn about the relationship between two distinct events, has been extensively studied in various animal taxa.

Initial Virome Characterization of the Common Cnidarian Lab Model Nematostella vectensis [PDF]
Viruses, 2020 The role of viruses in forming a stable holobiont has been the subject of extensive research in recent years. However, many emerging model organisms still lack any data on the composition of the associated viral communities.

Chromatin dynamics enable transcriptional rhythms in the cnidarian Nematostella vectensis [PDF]
PLOS Genetics, 2019 In animals, circadian rhythms are driven by oscillations in transcription, translation, and proteasomal degradation of highly conserved genes, resulting in diel cycles in the expression of numerous clock-regulated genes. Transcription is largely regulated through the binding of transcription factors to cis-regulatory elements within accessible regions ...

PaxA, but not PaxC, is required for cnidocyte development in the sea anemone Nematostella vectensis [PDF]
EvoDevo, 2017 Background Pax genes are a family of conserved transcription factors that regulate many aspects of developmental morphogenesis, notably the development of ectodermal sensory structures including eyes.

Daily cycle in oxygen consumption by the sea anemone Nematostella vectensis Stephenson [PDF]
Biology Open, 2016 In bilaterian animals, the circadian clock is intimately involved in regulating energetic metabolism. Although cnidarians exhibit diel behavioral rhythms including cycles in locomotor activity, tentacle extension and spawning, daily cycles in cnidarian ...

Using Nematostella vectensis to study the interactions between genome, epigenome and bacteria in a changing environment [PDF]
Frontiers in Marine Science, 2016 The phenotype of an animal cannot be explained entirely by its genes. It is now clear that factors other than the genome contribute to the ecology and evolution of animals.

L’anémone de merNematostella vectensis [PDF]
médecine/sciences, 2021 Nematostella, petite anémone de mer, possède de fascinantes propriétés, telles que la régénération du corps entier, l’absence de signes de vieillissement et d’affections liées à l’âge comme, par exemple, le développement de cancers. Elle se cultive aisément et se reproduit en laboratoire.

Single-cell atavism reveals an ancient mechanism of cell type diversification in a sea anemone
Nature Communications, 2023 Understanding how new cell types arise is essential for understanding the evolution of animal diversity. This study shows that a single gene, NvSox2, acts as a simple switch controlling the development of two alternative types of stinging cells in the ...

MAPK signaling is necessary for neurogenesis in Nematostella vectensis [PDF]
BMC Biology, 2016 The nerve net of Nematostella is generated using a conserved cascade of neurogenic transcription factors. For example, NvashA, a homolog of the achaete-scute family of basic helix-loop-helix transcription factors, is necessary and sufficient to specify a subset of embryonic neurons. However, positive regulators required for the expression of neurogenic
