Abstract

Ethnopharmacological relevance: Kaempferia pandurata Roxb., an edible tropical medicinal plant (Zingiberaceae), has been traditionally used to treat dental caries. However, its efficacy on inhibition of matrix metalloproteinase (MMP)-9 for preventing periodontal inflammation has been rarely studied to date. Aim of the study: This present study was focused to investigate the effects of the ethanolic extract of Kaempferia pandurata Roxb. on inhibition of Porphyromonas gingivalis supernatant-induced MMP-9 expression through activation of mitogen-activated protein kinase (MAPK) signaling pathways in human oral epidermoid KB cells. Materials and methods: MMP-9 expression and its signaling pathways in KB cells induced by Porphyromonas gingivalis supernatant were determined by gelatin zymogram, Western blotting and reporter gene assays. Results: Kaempferia pandurata significantly decreased MMP-9 expression at both protein and mRNA levels in a dose-dependent manner. Kaempferia pandurata interfered Porphyromonas gingivalis supernatant-induced MMP-9 expression in KB cells by downregulating MAPK phosphorylation (extracellular signal-related kinase 1/2, p38 kinase and c-Jun N-terminal kinase), inhibiting transcriptional expression (Elk1, c-Jun and c-Fos), and blocking AP-1 and NF-κB activities. Conclusions: Kaempferia pandurata could be employed as a candidate for MMP-9 inhibitor with therapeutic potential for treatment of periodontal inflammation.
