Antibiotics alter development and gene expression in the model cnidarian Nematostella vectensis

PeerJ
Background Antibiotics are commonly used for controlling microbial growth in diseased organisms. However, antibiotic treatments during early developmental stages can have negative impacts on development and physiology that could offset the positive ...

Structural Basis of GABAB Receptor Activation during Evolution

Advanced Science, Volume 12, Issue 37, October 6, 2025.
This study explores the structural and functional mechanisms of the drosophila GABAB receptor, a key role in neurotransmission. Using cryo‐EM, the research reveals how the receptor's activation differs from its human counterpart, highlighting unique evolutionary features.

Regulation ofNematostellaneural progenitors by SoxB, Notch and bHLH genes [PDF]

Development, 2015
Notch signalling, SoxB and Group A bHLH ‘proneural’ genes are conserved regulators of the neurogenic program in many bilaterians. However, the ancestry of their functions and interactions is not well understood. We address this question in the sea anemone Nematostella vectensis, a representative of the Cnidaria, the sister clade to the Bilateria.

Axis Patterning by BMPs: Cnidarian Network Reveals Evolutionary Constraints

Cell Reports, 2015
BMP signaling plays a crucial role in the establishment of the dorso-ventral body axis in bilaterally symmetric animals. However, the topologies of the bone morphogenetic protein (BMP) signaling networks vary drastically in different animal groups ...

Gastrulation in the cnidarian Nematostella vectensis occurs via invagination not ingression

Developmental Biology, 2007
Gastrulation is a central event in metazoan development, involving many cellular behaviors including invagination, delamination, and ingression. Understanding the cell biology underlying gastrulation in many different taxa will help clarify the evolution of gastrulation mechanisms. Gastrulation in the anthozoan cnidarian Nematostella vectensis has been

Graded FGF activity patterns distinct cell types within the apical sensory organ of the sea anemone Nematostella vectensis.

Developmental Biology
Bilaterian animals have evolved complex sensory organs comprised of distinct cell types that function coordinately to sense the environment. Each sensory unit has a defined architecture built from component cell types, including sensory cells, non ...

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

BioEssays, Volume 47, Issue 9, September 2025.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Unravelling the developmental and functional significance of an ancient Argonaute duplication

Nature Communications, 2020
The sea anemone Nematostella vectensis expresses miRNAs and two Argonaute (AGO) proteins. Here the authors show that NveAGO1 and NveAGO2 are loaded with overlapping but different sets of miRNAs and that NveAGO2 binds both miRNAs and endo-siRNAs. Both AGO

β‐Catenin localization in the ctenophore Mnemiopsis leidyi suggests an ancestral role in cell adhesion and nuclear function

Developmental Dynamics, Volume 254, Issue 9, Page 1055-1067, September 2025.
Abstract Background The emergence of multicellularity in animals marks a pivotal evolutionary event, which was likely enabled by molecular innovations in the way cells adhere and communicate with one another. β‐Catenin is significant to this transition due to its dual role as both a structural component in the cadherin–catenin complex and as a ...
