Spatial and temporal regulation of Wnt/beta-catenin signaling is essential for development of the retinal pigment epithelium

Original language description

Wnt/beta-catenin signaling is highly active in the dorsal retinal pigment epithelium (RPE) during eye development. To study the role of Wnt/beta-catenin signaling in the RPE development we used a conditional Cre/loxP system in mice to inactivate or ectopically activate Wnt/beta-catenin signaling in the RPE. Inactivation of Wnt/beta-catenin signaling results in transdifferentiation of RPE to neural retina (NR) as documented by downregulation of RPE-specific markers Mitf and Otx2 and ectopic expression ofNR-specific markers Chx10 and Rx, respectively. In contrast, ectopic activation of Wnt/beta-catenin signaling results in the disruption of the RPE patterning, indicating that precise spatial and temporal regulation of Wnt/beta-catenin signaling is required for normal RPE development. Combined, our data suggest that Wnt/beta-catenin signaling plays an essential role in development of RPE by maintaining or inducing expression of Mitf and Otx2.
