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.

Heat Stress Drives Rapid Viral and Antiviral Innate Immunity Activation in Hexacorallia

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT The class Hexacorallia, encompassing stony corals and sea anemones, plays a critical role in marine ecosystems. Coral bleaching, the disruption of the symbiosis between stony corals and zooxanthellate algae, is driven by seawater warming and further exacerbated by pathogenic microbes.

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

Studying Delta-Notch Signaling in Nematostella vectensis [PDF]

, 2019
The overall goal of this project is to investigate the role of epigenetics in the regeneration of the model organism, Nematostella vectensis. This model organism has emerged as an ideal system to study regeneration since it has the ability to fully ...

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).

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 ...

Comparative Analysis of Convergent Jellyfish Eyes Reveals Extensive Differences in Expression of Vision‐Related Genes

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Eyes have evolved in many different lineages, including several times within jellyfish, yet the relative contributions of shared and lineage‐specific genes to convergent eyes are not known. We find that three long‐diverged species of jellyfish have mostly divergent patterns of gene expression in their eye‐bearing tissues, suggesting a major role for ...
