SMEF suppresses RANKL-induced NF-κB and AP-1 activation in dose-dependent manner. (A–D) RAW 264.7 cells were pretreated with SMEF (0, 12.5, 25, and 50 µg/mL) for 12 h and then exposed to RANKL for 10 min. Cytosolic fractions were analyzed for protein content of IκB-α degradation, whole-cell lysates were used to determine phosphorylation levels of NF-κB p65, and nuclear fractions were analyzed for NF-κB p65 and AP-1(c-Jun) translocation (assayed by Western blotting as described in the Materials and Methods section).
