Western Blot, densitometric analysis and protein activation of CHO-K1 cells stimulated with RES and vitD alone and together. In a (ERK/MAPK), b (Akt), c (SOD) activations by ELISA are reported as means ± SD(%) of five independent experiments. In d (ERβ receptor) and e (VDR receptor) Western blot (on the left) and densitometric analysis (on the right) are reported. In the right column the specific densitometric analysis is reported and expressed as means ± SD(%) of five independent experiments. * p < 0.05 vs control; ** p < 0.05 vs RES alone; ^φ p < 0.05 vs vitD; the bars, p < 0.05 between RES + vitD at different times. RES = resveratrol 50 μM; vitD = vitamin D3 100 nM; RES + vitD = co-stimulation of RES 50 μM with vitD 100 nM
