Red ginseng oil (RGO) has been shown to possess anti-inflammatory and hepatoprotective activity. In this study, we evaluated the inhibitory effect of RGO on 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated neoplastic transformation of JB6 P+ cells. RGO pretreatment abolished the transformation of JB6 P+ cells challenged by TPA. RGO suppressed the transactivation of activator protein-1 (AP-1) and nuclear factor kappa B (NF-κB) transcription factors as well as protein levels of cyclooxygenase-2, cyclin D1, cyclin E, and Bcl-2 in the TPA-treated cells. Additionally, TPA-induced phosphorylations of extracellular signal-regulated kinases, 90 kDa ribosomal S6 kinase 2, c-Jun N-terminal kinases, and glycogen synthase kinase 3β were downregulated in the presence of RGO. Furthermore, RGO induced the nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated antioxidant enzyme heme oxygenase-1 (HO-1) expression, and effectively blocked the overproduction of TPA-induced reactive oxygen species. These results suggest that RGO exerts a potent chemopreventive activity in skin cell model.
