Outline of Final Research Achievements

Odontoblast-like cell line (KN-3) enhanced chemokines production through the innate immune receptor NOD1 and p38-AP-1 signaling pathway. Caffeic Acid Phenethyl Ester, which is one of polyphenols, reduced their production but induced VEGF production even under calcification induction conditions. Regarding the innate immune response, tolerance was observed in both odontoblasts and dental pulp fibroblasts. microRNAs (miRNAs) involve in the regulation of gene post-transcription and miRNAs whose expression was changed 2-fold in KN-3 cells were identified. These findings suggest that the applications of CAPE and post-transcriptional regulation, such as miRNA, may be useful for dental pulp preservation and calcification / regeneration therapies.
