Partial Rescue of the Amelogenin Null Dental Enamel Phenotype

Gerald K. Harrison, Darrin Simmons, Bill Daly, Hanson K. Fong et autres

The amelogenins are the most abundant secreted proteins in developing dental enamel. Enamel from amelogenin (Amelx) null mice is hypoplastic and disorganized, similar to that observed in X-linked forms of the human enamel defect amelogenesis imperfecta resulting from amelogenin gene mutations. Both …
