Curcumin Attenuates Asthmatic Airway Inflammation and Mucus Hypersecretion Involving a PPAR<i>γ</i>-Dependent NF-<i>κ</i>B Signaling Pathway In Vivo and In Vitro

<div>Curcumin inhibited IL-4-induced NF-<i>κ</i>B activation and DNA-binding activity in BEAS-2B cells. (a) Western blotting was performed to analyze the phosphorylation of NF-<i>κ</i>B p65 in BEAS-2B cells; (b) DNA-binding activity of NF-<i>κ</i>B p65 was measured by a TransAM™ p65 transcription factor ELISA kit.
