Abstract:
:Labial grooves in maxillary incisors have been reported in several wild-type rodent species. Previous studies have reported age-dependent labial grooves occur in moderate prevalence in C57BL/6 mice; however, very little is known about the occurrence of such grooves. In the present study, we observed age-dependent groove formation in C57BL/6 mice up to 26 months after birth and found that not only the frequency of the appearance of incisor grooves but also the number of grooves increased in an age-dependent manner. We examined the molecular mechanisms of age-dependent groove formation by performing DNA microarray analysis of the incisors of 12-month-old (12M) and 24-month-old (24M) mice. Amelx, encoding the major enamel matrix protein AMELOGENIN, was identified as a 12M-specific gene. Comparing with wild-type mice, the maxillary incisors of Amelx-/- mutants indicated the increase of the frequency and number of labial grooves. These findings suggested that the Amelx gene impacts the age-dependent appearance of the labial incisor groove in C57BL/6 mice.
