ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Diverse RNA interference strategies in early-branching metazoans

BMC Evolutionary Biology, 2018
Background Micro RNAs (miRNAs) and piwi interacting RNAs (piRNAs), along with the more ancient eukaryotic endogenous small interfering RNAs (endo-siRNAs) constitute the principal components of the RNA interference (RNAi) repertoire of most animals.

Transcription dynamics and regulation of heat shock protein genes during stress and development in the estuarine cnidarian Nematostella vectensis

bioRxiv
Heat shock proteins (HSPs) are conserved molecular chaperones that function in protecting cells from proteotoxic conditions. Most eukaryotes have multiple HSP genes that encode for proteins localizing in the cytoplasm, endoplasmic reticulum (ER), and ...

Larval swimming in the sea anemone Nematostella vectensis is sensitive to a broad light spectrum and exhibits a wavelength‐dependent behavioral switch

bioRxiv, 2023
In nearly all animals, light sensing mediated by opsin visual pigments is important for survival and reproduction. Eyeless light-sensing systems, though vital for many animals, have received relatively less attention than forms with charismatic or ...

Optimized husbandry and targeted gene-editing for the cnidarian Nematostella vectensis

bioRxiv, 2023
Optimized laboratory conditions for research models are crucial for the success of scientific projects. This includes the control of the entire life cycle, access to all developmental stages and maintaining stable physiological conditions.

Evidences That Host Genetic Background More Than the Environment Shapes the Microbiota of the Snail Bulinus truncatus, an Intermediate Host of Schistosoma Species

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.

Large-scale deorphanization of Nematostella vectensis neuropeptide G protein-coupled receptors supports the independent expansion of bilaterian and cnidarian peptidergic systems

bioRxiv
Neuropeptides are ancient signaling molecules in animals but only few peptide receptors are known outside bilaterians. Cnidarians possess a large number of G protein-coupled receptors (GPCRs) – the most common receptors of bilaterian neuropeptides – but ...

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

bioRxiv, 2023
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 ...

Coral Venom and Toxins as Protection Against Crown‐of‐Thorns Sea Star Attack

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Crown‐of‐thorns sea star (CoTS) outbreaks are a main cause of hard coral cover decline across the Indo‐Pacific, posing a major threat to the resilience of coral reefs. However, the drivers underlying CoTS feeding on preferred (e.g., Acropora species) versus non‐preferred (e.g., Porites species) are poorly understood. We hypothesised that coral

Experimental Tools to Study Regeneration in the Sea Anemone Nematostella vectensis

, 2020
Animal regeneration is a biological process leading to the reformation of injured or lost tissues/body parts. One of the most fascinating regenerative phenomena is the so-called whole-body regeneration, leading to the reformation of fully functional organisms within days after bisection.
