Associative learning in the cnidarian Nematostella vectensis

Proceedings of the National Academy of Sciences, 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 ...

Loss of Twist impairs tentacle development and induces epithelial neoplasia in the sea anemone Nematostella vectensis

bioRxiv
The basic helix-loop helix transcription factor Twist plays diverse roles in mesodermal development across bilaterians, but its function in cnidarians remains unclear.

The nascent RNA labelling compound 5-ethynyl uridine (EU) integrates into DNA in some animals [PDF]

BMC Molecular and Cell Biology
Background The detection of de novo synthesized mRNA transcripts is crucial for understanding the regulation of eukaryotic transcription. Using nucleoside or nucleotide analogues to label nascent RNA is potentially jeopardized by the ubiquitous presence ...

NvashA function reveals temporal differences in neural subtype generation in cnidarians [PDF]

Scientific Reports
Understanding how cnidarians pattern their nervous systems can provide insight into the ancestral mechanisms of neurogenesis that are shared with bilaterians, shedding light on the evolution of nervous systems.

Feeding-dependent tentacle development in the sea anemone Nematostella vectensis [PDF]

Nature Communications, 2020
How the developmental capacity of long-lived animals copes with fluctuations in the food supply is unclear. Here, the authors show using the sea anemone Nematostella vectensis that the crosstalk between Target of Rapamycin and fibroblast growth factor ...

β-catenin-driven endomesoderm specification is a Bilateria-specific novelty [PDF]

Nature Communications
Endomesoderm specification by a maternal β-catenin signal and body axis patterning by interpreting a gradient of zygotic Wnt/β-catenin signalling was suggested to predate the split between Bilateria and their sister clade Cnidaria.

miRNA-target complementarity in cnidarians resembles its counterpart in plants [PDF]

EMBO Reports
microRNAs (miRNAs) are important post-transcriptional regulators that activate silencing mechanisms by annealing to mRNA transcripts. While plant miRNAs match their targets with nearly-full complementarity leading to mRNA cleavage, miRNAs in most animals

Notch, β-catenin and MAPK signaling segregate endoderm and mesoderm in the diploblast Nematostella vectensis

bioRxiv
Cnidaria are typically considered diploblastic (i.e. consisting of two germ layers) in contrast to their triploblastic sister clade, the Bilateria. However, a recent study suggested that sea anemones and other cnidarians have three segregated germ layer ...

Prolonged starvation deepens quiescence in Vasa2/Piwi1-expressing cells of a sea anemone. [PDF]

PLoS Biology
Animals with lifelong growth adjust their growth rates to nutrient availability, yet the underlying cellular and molecular mechanisms remain poorly understood.

Doublecortin-like kinase is required for cnidocyte development in Nematostella vectensis

Neural Development
The complex morphology of neurons requires precise control of their microtubule cytoskeleton. This is achieved by microtubule-associated proteins (MAPs) that regulate the assembly and stability of microtubules, and transport of molecules and vesicles ...
