This federal Project Grant award, totaling $690,340.00, was provided by the National Institute of Dental and Craniofacial Research (NIDCR) under the Oral Diseases and Disorders Research program (CFDA 93.121). The grant supports research to study the active transcellular and intracellular phosphate (Pi) movements that dictate enamel mineralization processes during tooth development. The University of Southern California is the primary awardee and will utilize unique mouse models to examine the roles of specific Pi transport proteins (PIT1, NaPi2b, XPR1) in the secretory and maturation stages of amelogenesis. The research aims to achieve a paradigm shift in the understanding of genetic controls and mechanisms involved in enamel biomineralization. Key research activities include in situ hybridization, immunofluorescence, cell culture experiments, and advanced characterization of enamel architecture, composition, and mechanical properties in mutant mouse teeth. This 5-year project, with an award date of April 10, 2025, and a planned completion date of January 31, 2030, seeks to provide new insights that can improve dental practitioners' understanding of enamel formation and mineralization.
