Stimulatory effects of 6-methylsulfinylhexyl isothiocyanate on cultured human follicle dermal papilla cells

Abstract

Wasabi is a member of the Brassicaceae family and produces various isothiocyanates (ITCs). Because 6-methylsulfinylhexyl ITC (6-MSITC) is stable among wasabi ITCs, it has potential as a functional compound. Hair loss can have psychological and social effects on an individual because of its impact on appearance. In this study, we investigated the stimulatory effects of 6-MSITC by culturing on human follicle dermal papilla cells (DPCs). Results showed that 6-MSITC significantly promoted DPC proliferation and upregulated vascular endothelial growth factor (VEGF) mRNA levels compared to control. Furthermore, 6-MSITC significantly upregulated adenosine A2b receptor (ADORA2b) mRNA levels. Previous studies have reported that VEGF was induced through ADORA1 and ADORA2 pathways. We suggest that 6-MSITC stimulates hair growth on DPCs related to the upregulation of ADORA2b mRNA level. Thus, 6-MSITC may be used as a functional compound.
