RA-induced prominence-specific response resulted in distinctive regulation of Wnt and osteogenesis [mRNA-seq]


ABSTRACT: Proper retinoic acid (RA) signaling is essential for normal craniofacial development. Both excessive RA and RA deficiency in early embryonic stage led to a variety of craniofacial malformations, e.g., cleft palate, which have been investigated extensively. Dysregulated Wnt and Shh signaling were shown to underlie the pathogenesis of RA-induced craniofacial defects. In our present study, we showed a spatiotemporal-specific effect of RA signaling in regulating early development of facial prominences. While inhibited the Wnt activities in E12.5/E13.5 mouse palatal shelves, early exposure of excessive RA induced Wnt signaling and Wnt-related gene expression in mouse embryonic Frontonasal/Maxillary processes. A conserved regulatory network of miR-484-Fzd5 was identified to play critical roles in RA regulated craniofacial development using RNA-seq.
