Effects of FBL on the expressions of NF-κB p65 and P-NF-κB p65 in LPS-stimulated RAW 264.7 cells. Control group treated without LPS and FBL; model group treated with only 1 μg/mL LPS for 24 h; positive group treated with 44.70 mg/mL indometacin for 6 h and 1 μg/mL LPS for 24 h; and FBL groups treated with 62.50, 15.62, and 3.91 μg/mL FBL for 6 h, respectively, and 1 μg/mL LPS for 24 h. (a) The picture of NF-κB p65, P-NF-κB p65, and β-actin; (b) the ratio of NF-κB p65 to β-actin; and (c) the ratio of P-NF-κB p65 to β-actin. versus model group.
