Parallel evolution of gravity sensing [PDF]
Frontiers in Cell and Developmental BiologyOmnipresent gravity affects all living organisms; it was a vital factor in the past and the current bottleneck for future space exploration. However, little is known about the evolution of gravity sensing and the comparative biology of gravity reception.

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens
Methods in Molecular Biology, 2022 AbstractPlacozoans are a promising model system to study fundamental regeneration processes in a morphologically and genetically very simple animal. We here provide a brief introduction to the enigmatic Placozoa and summarize the state of the art of animal handling and experimental manipulation possibilities.

Evolution of glial cells: a non-bilaterian perspective [PDF]
Neural DevelopmentNervous systems of bilaterian animals generally consist of two cell types: neurons and glial cells. Despite accumulating data about the many important functions glial cells serve in bilaterian nervous systems, the evolutionary origin of this abundant ...

Early Animal Origin of BACE1 APP/Aβ Proteolytic Function [PDF]
BiologyAlzheimer’s disease is characterized, in part, by the accumulation of β-amyloid (Aβ) in the brain. Aβ is produced via the proteolysis of APP by BACE1 and γ-secretase.

Evolution of iGluR ligand specificity, polyamine regulation, and ion selectivity inferred from a placozoan epsilon receptor [PDF]
Communications BiologyEpsilon ionotropic glutamate receptors (iGluRs) are a recently defined clade of neurotransmitter receptors that are found in all major metazoan lineages that are distinct from α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), kainate, delta ...

Transposon-derived transcription factors across metazoans
Frontiers in Cell and Developmental Biology, 2023 Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788
