Spatiotemporal Characterization of Cyclooxygenase Pathway Enzymes During Vertebrate Embryonic Development
Leathers et al., Developmental Biology. 2025.
https://pubmed.ncbi.nlm.nih.gov/39581452/
The cyclooxygenase (COX) pathway plays a fundamental role in embryonic development. Disruptions of the COX pathway during pregnancy cause developmental anomalies, including craniofacial clefts, impaired gut innervation, and neural tube defects in the embryo. Researchers used Gallus gallus embryos to study the expression of COX pathway enzymes during neurulation. COX-1 protein expression was upregulated in cells undergoing mitosis, whereas COX-2 protein expression was ubiquitous. This study provides spatiotemporal expression data of COX pathway enzymes at key embryonic development stages in G. gallus and guides future studies focused on defining the role of these enzymes during embryonic development.

Promoting Validation and Cross-Phylogenetic Integration in Model Organism Research
Cheng et al., Disease Models & Mechanisms. 2022.
https://www.doi.org/10.1242/dmm.049600
Model organisms are essential for biomedical research and therapeutic development, but translation of such research to the clinic is low. The authors summarized discussions from an NIH virtual workshop series, titled “Validation of Animal Models and Tools for Biomedical Research,” held from 2020 to 2021. They described challenges and opportunities for developing and integrating tools and resources and provided suggestions for improving the rigor, validation, reproducibility, and translatability of model organism research.
