Research Abstract |
In this project, we examined the molecular mechanism of caries progression caused by dentin pulp complex derived MMPs. First, we examined the secretion of MMP-1 and MMP-3 from cultured dental pulp fibroblast. Pro-inflammatory cytokine TNFa increased secretion of the MMPs. We found JNK inhibitor SP601245 suppressed TNFa induced MMP-3 secretion. Next, to know the key transcription factor for the MMP-3 production in response to TNFa, we had screened possible transcription factors and found CREB as a candidate. To elucidate whether the activity of CREB is controlled by JNK1/2, we conducted pharmacological and genetic suppression of JNK1/2 and found that suppression of JNK 1/2 resulted in deactivation of CREB.
