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.

Genetic Diversity of 1,845 Rhesus Macaques Improves Genetic Variation Interpretation and Identifies Disease Models

Nonhuman primates are ideal models for certain human diseases, including retinal and neurodevelopmental disorders. Using a reverse genetics approach, researchers profiled the genetic diversity of rhesus macaque populations across eight primate research centers in the United States and uncovered rhesus macaques carrying naturally occurring pathogenic mutations. They identified more than 47,000 single-nucleotide variants in 374 genes that had been previously linked with retinal and neurodevelopmental disorders in humans. These newly identified variants can be used to study human disease pathology and to test novel treatments. Supported by ORIP (P51OD011107, P51OD011106, P40OD012217, S10OD032189), NEI, NIAID, and NIMH.
