Systematic evaluation of scallop (Argopecten irradians) SoxH reveals its crucial role in spermiogenesis with limited evidence for sex determination

Communications Biology
The transcription factor Sox30 (SoxH), a conserved regulator of vertebrate spermatogenesis, remains poorly characterized in mollusks, despite emerging evidence of its potential role in sex regulation.

Bony pseudoteeth of extinct pelagic birds (Aves, Odontopterygiformes) formed through a response of bone cells to tooth-specific epithelial signals under unique conditions

Scientific Reports, 2018
Modern birds (crown group birds, called Neornithes) are toothless; however, the extinct neornithine Odontopterygiformes possessed bone excrescences (pseudoteeth) which resembled teeth, distributed sequentially by size along jaws.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

Biological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

Gene burden meta‐analysis of 748 879 individuals identifies LGI1‐ADAM23 protein complex association with epilepsy

Epilepsia, EarlyView.
Abstract Epilepsy affects more than 50 million individuals globally and has a substantial genetic component that remains to be completely understood. Traditional studies have focused on severe, early onset cases enrolled through clinical or research settings.

Single-cell RNA sequencing reveals cellular heterogeneity and gonadal niche interactions in the hermaphroditic scallop Argopecten irradians

Water Biology and Security
The process of gonadal development necessitates the self-renewal and differentiation of germ cells, which is a complex and precisely regulated procedure that is inextricably linked with the gonadal microenvironment.

Building brains that can evolve: Challenges and prospects for evo-devo neurobiology

Mètode Science Studies Journal: Annual Review, 2017
Evo-devo biology involves cross-species comparisons of entire developmental trajectories, not just of adult forms. This approach has proven very successful in general morphology, but its application to neurobiological problems is still relatively new ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Regeneration of the lizard heart after cryoinjury

Experimental Physiology, EarlyView.
Abstract Lizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regeneration in the leopard gecko (Eublepharis macularius) to fill the knowledge gap between traditional models of poikilothermic (zebrafish) and ...

Core histone families of mollusca: systematic identification, evolutionary insights, and functional analysis

BMC Genomics
Background Histones are the basic packaging units of eukaryotic DNA and are essential for the dynamics of chromatin and the regulation of epigenetics. Canonical histones and their variants exhibit important functional differences in biological processes.
