Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Cell-state transitions and collective cell movement generate an endoderm-like region in gastruloids

eLife, 2022
Shaping the animal body plan is a complex process that involves the spatial organization and patterning of the different germ layers. Recent advances in live imaging have started to unravel the cellular choreography underlying this process in mammals ...

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

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Dad's Diet Shapes the Future: How Paternal Nutrition Impacts Placental Development and Childhood Metabolic Health

Molecular Nutrition &Food Research, EarlyView.
This review highlights the emerging connection between paternal nutrition‐induced sperm epigenetic changes and placental phenotypes that may influence offspring metabolic health. An accompanying interactive ShinyApp allows exploration of these sperm–placenta gene networks, a framework for future research seeking to explore candidate biomarkers or ...

Spinal dysraphism illustrated; Embroyology revisited

Indian Journal of Radiology and Imaging, 2017
Spinal cord development occurs through three consecutive periods of gastrulation, primary nerulation and secondary neurulation. Aberration in these stages causes abnormalities of the spine and spinal cord, collectively referred as spinal dysraphism. They

Protein Target Highlights in CASP16: Insights From the Structure Providers

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT This article presents an in‐depth analysis of selected CASP16 targets, with a focus on their biological and functional significance. The authors highlight the most relevant features of the target proteins and discuss how well these were reproduced in the submitted predictions.

Interactions between the bone morphogenetic protein and the planar cell polarity pathways lead to distinctive ethanol‐induced facial defects

Alcohol, Clinical and Experimental Research, EarlyView.
Gene–ethanol interactions lie at the heart of FASD. However, the relationship between ethanol‐sensitive genes and the timing and duration of exposure is not well‐understood. Using morphometric and multivariate analyses in zebrafish, vangl2 and gpc4 mutants are ethanol‐sensitive from 10 to 24 h postfertilization, not before or after, leading to facial ...

In vivo modeling of lethal congenital contracture syndrome 1 suggests pathomechanisms in cellular stress responses

The FEBS Journal, EarlyView.
Gle1 knockout mice fail to segregate cell lineages at the blastocyst stage, resulting in very early embryonic lethality. Gle1 knock‐in (KI) mice harboring a pathogenic variant giving rise to lethal congenital contracture syndrome 1 show both known and novel innervation defects, supportive of multiorgan pathology in human fetuses.
