Corneal dysmorphologies (CDs) are a group of acquired but predominantly genetically inherited eye disorders that cause progressive vision loss and can be associated with systemic abnormalities. This study aimed to identify candidate CD genes in humans by looking at knockout mice with targeted deletions of orthologous genes that exhibited statistically significant corneal abnormalities. Analysis of data from 8,707 knockout mouse lines identified 213 candidate CD genes; 176 (83%) genes have not been implicated previously in CD. Bioinformatic analyses implicated candidate genes in several signaling pathways (e.g., integrin signaling pathway, cytoskeletal regulation by Rho GTPase, FAS signaling pathway), which are potential therapeutic targets.

Spatiotemporal Characterization of Cyclooxygenase Pathway Enzymes During Vertebrate Embryonic Development

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.
