| Outline of Final Research Achievements |
It is reported that the Slc39a/Zip13 is related to biosynthesis of Type I collagen. Although Zip13 KO mice in root dentine observe the qualitative abnormality for type I collagen, it is still obscure to the onset of Type V collagen. In this study we observed to the onset of type V collagen. As results, the reaction to the antibody of type V and III collagen were not observed both in Zip13 WT and KO mice by ISH. However, the antibody of type I was reacted at alveolar bone in Zip13 WT mice, but observed in not only at alveolar bone but also in root abnormal dentine in Zip13 KO mice by immunohistochemical staining. All over results suggests that the non-collagenous protein such as DSPP, and/or DSP are related to the deposition of qualitative abnormal root dentine in Zip13 KO mice.
