Objectives : The purpose of the study is to examine the cell growth effect and autophagy effect of Scutellariae Radix by ethanol extract in SCC 25 cells. Methods : Cell growth inhibitory effect and autophagy induced by Scutellariae Radix were confirmed by WST-1 assay, monodansylcadaverine(MDC) stain, and flow cytometry by acridine orange(AO) stain. Results : The Scutellariae Radix treatment decreased the cell proliferation in a dose and time dependent manner. Scutellariae Radix has anticancer effects that autophagic vacuoles were apparent by MDC and AO staining in SCC 25 cells. Conclusions : Scutellariae Radix showed anticancer activity against SCC 25 cells via autophagy. The data provided the possibility that Scutellariae Radix may potentially contribute to oral cancer treatment.
