Slc26a2-mediated sulfate metabolism is important in tooth development.

ABSTRACT: The sulfate transporter gene SLC26A2 is crucial for skeletal formation, as evidenced by its role in diastrophic dysplasia, a type of skeletal dysplasia in humans. Although SLC26A2-related chondrodysplasia also affects craniofacial and tooth development, its specific role in these processes remains unclear. In this study, we explored the pivotal roles of SLC26A2-mediated sulfate metabolism during tooth development. We found that Slc26a2 was predominantly expressed in dental tissues, including odontoblasts and ameloblasts. Slc26a2 knockout (Slc26a2-KO-Δexon2) mice exhibited distinct craniofacial abnormalities, such as a retrognathic upper jaw, small upper incisors and upper molar hypoplasia. These mice also showed flattened odontoblasts and loss of nuclear polarity in upper incisors and mola
