Quince peel polyphenolic extract blocks the activation of NF-κB. LS174 cells were treated with vehicle or with Peph (5 µg/ml) for 24, 48 and 72 h. Protein extracts (30 µg) prepared were analyzed by western blotting using the indicated antibodies. β-actin was used as a loading control. Data are representative of three independent experiments
