Fig. 2From: 1,25-dihydroxyvitamin D3 suppresses lipopolysaccharide-induced interleukin-6 production through aryl hydrocarbon receptor/nuclear factor-κB signaling in oral epithelial cellsVDR, AhR and CYP1A1 expressions in LPS-treated oral epithelial cells were examined using western blot analysis. OKF6/TERT-2 cells were cultured for 6 h (a), 12 h (b), 24 h (c) or 48 h (d), in the presence of LPS (1 μg/ml) and 1,25D3 (0, 10, 20, or 30 nM)Back to article page
