Hinokitiol increases the angiogenic potential of dental pulp cells through ERK and p38MAPK activation and hypoxia-inducible factor-1α (HIF-1α) upregulation.

Abstract:

:Hinokitiol, a natural iron-chelating agent, is known to have diverse biological and pharmacological activities in various cell types. However, the effect of hinokitiol on dental pulp cells has not yet been reported. In this study, hinokitiol increases hypoxia-inducible factor-1α (HIF-1α) protein levels and vascular endothelial growth factor (VEGF) secretion in human dental pulp cells. The extracellular-signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) pathways are involved in hinokitiol-induced HIF-1α protein expression in dental pulp cells. Conditioned media from hinokitiol-treated pulp cells enhances angiogenesis in vitro and in vivo. Overall, these results show that hinokitiol promotes ERK and p38MAPK activation and HIF-1α-induced VEGF production, thus increasing the angiogenic potential of dental pulp cells.
