Project description:We show that loss of Arid1a impairs the differentiation-associated cell cycle arrest of tooth root progenitors through Hh signaling regulation, leading to shortened roots. Our data suggest that Plagl1, as a cofactor, endows Arid1a with its cell type/spatial functional specificity.

Project description:Primary cilia function as critical sensory organelles that mediate multiple signaling pathways, including the Hedgehog (Hh) pathway, which is essential for organ patterning and morphogenesis. Disruptions in Hh signaling have been implicated in supernumerary tooth formation and molar fusion in mutant mice. Cilk1, a highly conserved serine/threonine-protein kinase localized within primary cilia, plays a critical role in ciliary transport. Loss of Cilk1 results in severe ciliopathy phenotypes, including polydactyly, edema, and cleft palate. However, the role of Cilk1 in tooth development remains unexplored. In this study, we investigated the role of Cilk1 in tooth development. Cilk1 deficiency resulted in downregulation of Hh target genes, leading to the formation of supernumerary teeth. This study reveals a previously unrecognized role of Cilk1 in controlling tooth morphology via Hh signaling.
Project description:This study aimed to perform transcriptome profiling of Nfic-/- and corresponding control tooth germ at root initiation stage to identify differentially expressed for key regulators of root development. Coordination between the Hertwig’s Epithelial Root Sheath (HERS) and apical papilla (AP) is crucial for proper root development process. The Hedgehog (Hh) signaling pathway and Nfic are both involved in tooth root development.
